After a Decade, the Bathroom Wall is Done!

It’s hard to imagine how we lived with our grey and orange unfinished bathroom wall for a decade. It wasn’t pretty, but it worked. The task of doing a whole-wall mosaic seemed too daunting and permanent to commit to a design. Finally, with the kid off to college, it needed to get finished.

Using the templates we printed a decade ago to lay this wall out, we decided to shrink the mosaic to just a border around the window with the rest being large white tiles. It seemed more digestible now with only 10 inches of mosaic on the sides and 4 on the top and bottom. It should also be easier to clean and less overwhelmingly busy to look at.

Outside the bathroom window would be a long planned greenhouse window. I set to working on the frame in the studio using old steel bought for this purpose years ago and 1/2″ acrylic gifted to me early in the pandemic. Grind, chop, weld, grind, paint. I added a sturdy lifting point on the top guessing at where the center of gravity would end up once the acrylic was in. It was pretty hard to choose a sealant that would work with painted steel and acrylic and allow for some movement as the temperature swings from season to season. I took some chances using an EPDM sealant to affix the acrylic into the frame. I scuffed up the acrylic edge to improve my chances of it bonding. Only a few seasonal cycles will prove if it works. Between the frame and the uneven brick surface we used adhesive backed 1×1 inch weather stripping foam. On a night in December, we gathered some neighbors and a block and tackle and got to lifting all 200lbs of it into place careful not to damage the weather stripping. With the extra hands of neighbors it went quickly; the greenhouse window box was bolted in place within about 10 minutes without any panels falling out, although one does have a leaky gap from the flexing experienced it during the lift; I’ll reseal in the spring.

Since the greenhouse window is keeping the elements [mostly] out, we removed the old, pest eaten double hung wooden window. I made some simple window trim to match the rest of the bathroom and nailed it to the treated frame I replaced years before. The end result is a MUCH larger opening in the wall that lets in tons of light. You can stick your head into the box to look down the alley which is important now that you can’t open the window.

We started with the big 16×8 inch white tiles being extra careful to nail the spacing and flatness. We left some squares out on the sides to work in some elements that to extend out of the square. A pattern was drawn on with chalk, transferred to a mesh backer and we laid everything out in the basement over the next few weeks. We glued down the tiles which allowed us to carry them up, test fit, fix and eventually mortar into place. Sure beats placing them one at a time like Siri did with the shower curbing 10 years ago.

With the holidays, it took a few weeks to get back to it, but eventually we were done laying things out. There is a mix of 1/2 inch and 1/4 tiles here making it even more of a pain. Getting small enough chunks of 1/2 inch tile was hard and there was a lot of use of a tile saw to get everything to fit together without having to spend hours searching for the perfect piece each time.

We carried up a section at a time on the mesh. Everything was mortared into place in a pretty fast paced 4 hour evening. Next up was grout. We gave it a few days to harden the mortar first and then went to it.

To finish things off, we gathered some plants from friends and even IKEA. There will be more to add over time, but this is a good step toward privacy. If the plants are not enough a blackout curtain can be rolled down. Finally some real privacy in the bathroom after a decade. As for the mosaic, the end result is pretty great. The design is a vine with some very abstract flowers and a few leaves with a background that fades from light to dark blue as you go up. It’s been cleaned and sealed with our big reveal being today at our Chinese New Year party. It’s good to be done.

Paid Off the Mortgage

Today is a huge day at Formstone Castle. We’ve paid off the mortgage! We set an ambitious goal to pay the house off in 5 years, but still set the terms of the mortgage to 10. 8 years in, and during a pandemic, we’ve managed to scrape together enough money to make those final payments.

We were hoping to have a huge 4th of July block party and bash to celebrate, but Covid-19 has postponed that plan. For now we’ll enjoy the view from the deck and have a little champagne with Siri’s family over Zoom.

Mesh Panels

This year started with the idea to clear out some Mind Freight(TM) from the warehouse of my brain. Biggest among these mental heavy lifts was finishing up the deck. The physical manifestation of this is the steel stored on my basement floor for the last few years waiting for me to get motivated enough to finish the stairs for the deck.

Before the pandemic ground things to a halt this winter I managed to finish some tricky posts going up the wood stairway. Each one was unique so there was no good way to make a jig. I had to figure out a way to keep the visual language consistent even on these unique posts. One has the only outside angle on the deck and the other has an inch and a half offset. Another consideration is that they reinforce the important connection between the stringers and the deck. Lots of measuring, strings, and running up & down from the roof to the back yard.

Next were the mesh panels. Two rectangle panels were made to finish off the top deck: one big and one little. I’ve made 15 already so the final two came out quick. The hard ones were next though. 6 odd shaped ones coming down from the stairs and transitioning into the spiral landing. Again, lots of running up & down. Saved some time making cardboard templates, but even then things needed to be tacked and checked.

In here I was also working on the fill mesh for the spiral. With 16 to make, I was not going to be able to fit each one exactly so I decided to build a wooden jig to weld them up in. A day of cutting pieces to shape – some with the dry cut saw, some with the plasma cutter if it seemed to dangerous of an angle for the saw and LOTS AND LOTS of angle grinding. Another day of welding… lots and lots of ends of mesh… and of course angle grinding to clean up the faces. A day of drilling holes. And two days of painting.

It took some flexing and some creativity to hold things into place, mark them and drill holes, but I worked my way up and luckily everything ended up decently aligned.

Still need to figure out a cap and the graspable handrail, but at least the terror of falling over the edge is gone. It’s starting to feel like a deck!

The Giant Deck Update

The deck was something we first drew up right after we bought the house.  We’ve pretty much stuck with the original idea since then: A deck on the roof, a deck off the 2nd floor and a sunken in hot tub.  It was the icing on the cake once we finished everything else.  Finally we were ready to make it happen.

I clear my schedule starting in July 2016 by quitting my job of 4 years.  That really helped free up some time!  We pulled a demolition permit and I got to take out some end-of-career rage with a sledge hammer and prybar.  The first squares went well prying up as one piece and then breaking to pieces by dropping them.  Then we found the 2nd layer.  Just like the rest of the house, when things started to fall apart, they just covered them up with another layer.  This took weeks and I managed to lose a finger nail in the process, but it was good work and enjoyed being outside getting a workout.

Drawings and Permits (Aug 2016)

While this was happening we started the next step of getting an official architect to put his name on some drawings so we could pull the permits.  We were dreading this step as it was the first time we really had to get the city and a third party involved.  In the end it cost us $900 for the drawings and another hundred or so dollars for the permits.  Including a demolition permit to take out the old patio.

“Prep work”

The next few months can only be described as “prep work”.  Unfortunately, prep work gets a little complicated when I’m involved.  I don’t like things to build onto things that are wrong.  Still enjoying the weather, I dug a trench to the shack and buried two conduit pipes just in case I needed them one day.  Then came fixing the drainage at the back of the house.  From early on the concrete sloped towards the back door and during heavy rains would actually back up into the house, rotting away the boards under the rear entryway.   Also, below grade the mortar wasn’t looking too good so I repointed that. While I was added, I fixed up some problem spots near the kitchen window / sink drain.

At this point things are starting to get a little crazy. We’ve got to jack up the corner up the house so that we can dig a proper footer and build it back up in order to put the house back down on it. We also take off the back corner of the house and have to button it up in a day.

Redoing the Back Entry (Sept 2016)

There also was a really awkward stair setup with a terribly built set of 3 steps that came halfway out into the 6′ wide room.  To fix this we decided to raise the floor 12 inches, adding one step down to the basement, one to the outside and reduce the 3 up into the house down to one stair.

We couldn’t just lay down a new floor though.  For this we had to dig down 30 inches and pour a new footer and build up a short 5′ cinderblock foundation back up to where we could put down a treated sill board and then lay down some joists.  It was all quite an undertaking.  The walls had to come off the back of the corner of the 1st floor.  A little at a time so we wouldn’t be wide open for too long.  I jacked up the 6×6 post in the corner that held up Siri’s office above and cut off it’s completely rotted away nub so that I could rest it on a treated 6×6 carrying that load back down to the new footer.

The Roof (Oct 2016)

Now the next part of “prep work” was what most people consider a major project by itself: a new roof.  We knew the old roof needed to be replaced soon and it was better done before rather than after the deck and we didn’t want to be throwing all the old roof material debris down onto the new deck below.  The new deck was an EPDM rubber roof.  These systems are all made by car tire companies and its essentially a giant sheet of inner tube rubber and a big bucket of rubber cement.  Out of the other roofing options this one lasts a pretty long time (50ish years) and is generally the most expensive option around Baltimore.  Strangely it seems to also be one of the easiest for a DIY job.  No major tool investments as it’s not something you need to torch down or heat weld together.  It’s just like a bike tire: glue down on both surfaces, wait until it gets tacky, carefully make contact (one chance to get it right!) and go over it with a broom or a roller to apply pressure.  All the factory training videos on on youtube.  It does need a fresh surface to be glued to so tearing off all the old and adding a fresh layer of OSB was needed.  It was easy work.  We cut the old roof with an end-of-life circular saw blade into manageable 3’x3′ squares.

Cedar Shakes (Nov 2016)

Now that we had the new walls and that damn yellow siding was gone I could cover it all up again.  This is another thing that was in my plans from that first Sketchup drawing; I wanted ceder shakes.  We ordered a few squares of shakes.

Figuring the next steps would go ahead smoothly we went ahead and ordered our lumber. We jumped the gun though. I think the order was delivered in October and we didn’t get beyond posts until the following June.

The first deck to go up was on the roof. I had already added in posts back in October when we did the roofing. Framing of the deck took about 2 days and I can’t for the life of me find a photo of that process.

Footers (July 2017)

Finally we can start a deck… or can we?  Footers!  Our architect drew in some pretty serious footers for our tub supporting deck.  18″ x 24″.. oval. I got some 18″ forms and for the oval ones, cut them in half, added 6″ of plywood and made my own ovals. It was a challenge because things got really busy with Light City starting in 2017.

After freezing, filling with water, collapsing, being dug out again, I finally got around to footers done in July 2017, nearly a year after demolition started. In addition to being 18″ x 24″ ovals, the party wall footers had go go behind the 36″ deep (code is 30″ here) holes down to 48″. Turns out that is a LOT of dirt. We had to move out so much dirt and then move back in all the sand, gravel, and cement. All in buckets from the street.

The drawing also called for rebar reinforcements, so I fabbed some up with the welder. There were several different sized for all the different shapes and depths.

Finally it was time for concrete. Our amazing and magical friend Becca ran the cement mixer the first day. It was 100+ degrees under a tarp that mostly just made it more still, humid and converted the sun that hit the top if it to heat underneath. It took a 2nd day with Siri running the cement mixer to get the last ones done.

Going up! After a little break to let the concrete cure… I think a few weeks? We erected the posts. Lots of posts. Our drawings called for twelve 6×6 posts. Four of those form a small, lower structure that exists only to hold the hot tub. Again with the Becca’s help, Siri and I flew through this step.

Because of the hot tub, and wanting to keep the party going underneath on the patio, we chose to add our rubber roofing material to direct water to gutters.

Hot Tub Lift (Aug 2017)

Since the start of this plan, we’ve been asked pretty much the same question over and over: how are you getting the hot tub up there? Our architect recommended getting a crane, but at $5000, it went well beyond our budget, plus I don’t think a crane could put outriggers far enough out on Castle Street to clear the 35′ house. Luckily I had lots of time to day dream about this solution. Here is how I did it.

Prefabricate the tub deck platform on the ground. Using the main deck, I could lift the platform up and stage it off to the side on top of the scaffolding. Lift the tub straight up and slide the deck under it.

The lift! With the help of dad and our friend Logan, we used (against the manufacturer’s recommendation) four comealongs with straps slung around boards run underneath the tub. It was a slow process, but eventually we got the tub about 3″ above where it needed to end up. Careful to not get underneath too much, we installed the doubled 2×12 beams onto the posts, put down two pieces of rigid conduit as rails, and slid the platform into place. Once it was settled into place and a few missing pieces added, we lowered the tub onto the platform.

It was pretty quick after that to add the rubber and decking boards. Then it was off to Burning Man, but that’s a whole other story.

The Patio (Nov 2017)

With all the messy stuff done above, and not wanting to walk on gravel forever, next step was the brick pavers. Just like taking out the old concrete, we brought in the new materials 2 buckets at a time. A layer of stones to help drain away any water, a layer of semi-perm membrane, sand and finally 800 or so reclaimed bricks from The Loading Dock.

Railings Part 1 (Feb 2018)

I’ve wanted to do steel posts with metal mesh from the get go as I wanted to see as clearly as possible the trees while in the hot tub. It took a little while to get to them. We even had a few hot tub parties on a deck 15′ off the ground with no railings at all. Safety 3rd!

Winter outdoor metal fabrication is not my favorite thing, but we a week or two with warmish weather so I started on my posts and squares. I painted them just before we left on a trip to Puerto Rico and let them dry inside while we were away. I put up what I had done for our Chinese New Year party after we returned with early arriving guests helping to drill the last holes. With no mesh, we just zig-zagged paracord to hopefully catch anyone from going through until we could track down mesh.

Railings Part 2 (Oct 2018)

Due to Light City 2018’s crazy schedule and having to build some lasers again to pay the bills, things sat pretty still for 8 months. Over that time we tracked down a galvanized 3″ mesh. For some reason, there wasn’t any locally that couldn’t be called chicken fencing. What we ended up ordering from Boston, was 11 gauge. So back to posts and rectangles I went. It took until around Solstice to get everything cut, welded, painted, and installed.

Up Next: Stairs

Light City 2018 – What Lies Beneath

In March we teased of our massive light art project entitled What Lies Beneath. It was all consuming in both time and space.  Now that we’re on the other side looking back at it, it seemed to go smoothly, but it took everything we had to pull it off.  Here is a look back on What Lies Beneath.

Motivated by the values of Formstone Castle, we brought together a group of artists and pushed them out of their comfort zone to try new things with the skills we knew they could develop.  Justin Duvall brought his strengths as an an animator of strange creatures, Kate Haberer brought in her skills as an illustrator and Andrew Dixon brought in his skills as a graphic designer.  Each of them created a short clip, not fulling knowing what it would look like on a first of it’s kind display.  For backup, I filmed some clips at the aquarium to flesh it all out.  Last but not least, Adam T. Rush returned to a Formstone Castle project creating a score tying it all together.  Here is the result:

Now what’s behind this magic?  I’ll try to break down the 6 months of work and try to explain it for those that want to see what lies beneath.

From the ground up this was designed to be modular.  Each section is 10 feet wide and 37 feet long.  Each module has it’s own power supply, controller and ethernet switch.  Plug it into 120v-240v power and into it’s neighbor for signal. We built 14 modules, but for safety reasons, we only installed 12 for Light City.

1500 Watts (24v) with 8 channel LED control over Ethernet. We had 12 of these installed.

To keep it all dry, all the LED strips are run through 1″ vinyl tubing.

Because we could only supply power from one end and had to send that power from shore, the power wires were up to 20′ long + 37′ if you count the LED strips. For this reason our LED strips are custom 24v with a thicker PCB foil. For WS2811 LEDs, our 24v requirement meant each pixel contained 6 LEDs. This worked out in our favor. Each 10 ft module contained 16 LED strips making the length of our pixels and the spacing between our strips the same. 1:1 made mapping much easier for our animators. Here are some spicy facts:

  • 192 LED strips (+ spares) @ 11 meters each
  • 2.1km of LED strips
  • 330 LEDs per strip
  • 63,360 LEDs
  • 192 x 55 pixels
  • 1500 watts x 12 = 18,000 watts of power

Special thanks to all our friends who helped us to pull this off

Light City 2017 – Part II

Following Puerto Rico, I was offered a gig building lasers for a company in Baltimore.  I had been out of work for a few months and needed the money so I took on several weeks to build 30 lasers for Paul McCartney’s world tour.  It would test my time management skills, but the practice in soldering and crimping would save my butt in the end.

The next few months was a balancing act.  Every hour not working on lasers was money lost, but an hour less to work on the couch.  We had a few things to figure out and build beyond the upgraded brakes and wheels.  A coffee table, side pods covering the wheels, back and front panels and chandeliers.

Luckily we had some collaborators all doing their part.  Adam had the music pretty much by January so we had music to listen to while working.

Charlotte was working on the creature outfit.  She had the ghillie suit but wasn’t sure where to go next.  We wanted to hang out anyway so we headed out on an expedition to find inspiration around the harbor itself.  This helped her get a idea of the way the trash and weeds and bay become intertwined.

An inspirational walk

And Katlyn worked on the mural for the back first drawing up a everything on the computer in order set up the layers and then being able to project it on to the wall.  The end result is pretty incredible and a piece of hangable art all by itself.

Katlyn’s amazing mural showing The Wave, a painting from Baltimore’s sister city Kawasaki Japan as it crashes over the Fells Point Pier

First I found time to build up the side pods.  We used thin plywood panels reinforced with bulkheads and mostly wood glued together.  This we covered with chrome vinyl.

It’s pretty amazing how close this turned out to the renderings considering I was just winging it the whole time.

From there we played around with our materials and found a cool way to put LED strips behind chrome covered acrylic.  When the lights were off it was just chrome, but when they were on the would since right through.

<iframe width=”854″ height=”480″ src=”” frameborder=”0″ allow=”autoplay; encrypted-media” allowfullscreen></iframe>

For the table we decided we wanted it to look thick, but not weigh or cost a ton so we drew it up on Sketchup to get the most out of a single 4×8 sheet of 3/8″ acrylic.  We doubled up the perimeter to 3/4″ by welding them together and added 4″ underneath to make it more rigid.  We sort of got it right, but with a ton of mini bubbles trapped inside.  Whatever!  Cleaned up the sides and lit it with a strip in the center.  It was amazing at night.  The acrylic carries the light from the led’s through to the edge where it GLOWS.

Once the table was done we needed to put some things on it.  A global positioning system and some disco snacks.

I had to wire up each piece of fruit.  4 male, 4 female pins on each.  Something like 80 pins to crimp total.  Can plug it into a regular 12v power brick though and is controlled by a remote so we can use it anywhere in the house.

In the end we built a pretty sweet couch

Beyond the physical couch was the hours of work provided by our performance artists / spotters.  For six hours each night, our team of dedicated workers would suit up and escort the couch around little piece of the festival.

Light City 2017 – Part 1

It has been a busy winter at Formstone Castle (Actually it’s been super busy since July, but those posts will come later).

Last spring we visited the very first Light City Baltimore festival. ¬†Saturday night in particular was a wild conversion of friends, neighbors, art, music, and weather. ¬†We began thinking of ways to get involved in 2017, but couldn’t quite figure out what we should do. ¬†It wasn’t until May when we resurrected the Kinetic Couch that we focused on an idea. ¬†Our 2016 KSR was a great success. ¬†We won our second (2/2!) major award: “The Next To Last Award”.

We’re still not exactly sure where the convergence of ideas came from, but we decided to apply the look of Japanese Dekotora trucks with our 3 person couch and coffee table. In about 3 weeks we put together a killer proposal for Light City 2017. ¬†In the process of writing the proposal the project evolved, took on collaborators, fed back their input into the piece over and over until we came up with this:

In the process we also roped in artist friends to collaborate.  Katlyn Wyllie would make the mural on the back, Charlotte Hager would make the costume for the creature, Adam Rush would make a 6 hour music mix and Siri and I would build the couch and coordinate all of the other details.

As winter settled in, we wanted to have lights and controllers in hand to being building prototypes and playing with code.  Our first orders were placed within hours of hearing we were selected so that we could have them by Christmas to play with.  We wanted to order as much as we could locally, but some parts did come from over seas such as the controllers and WS2811 LED light strips.   The battery was sourced from Best Battery in Baltimore.  It is a giant 12v 150lb 255Ah deep cycle battery.  This was all set up in the basement with our fuses and wires run up through our floor vent into the living room where we used the lights as our Christmas tree, but also to test our ability to power them from the battery, charge the batter and program the controllers.  If you got our Christmas card, this was in the background.

We also started the the process of strengthening the rear wheels and brake as they’d need to hold several hundred additional pounds with the new design. ¬†I wanted cast aluminum wheels to be able to handle serious side loads. ¬†A quick trip to Baltimore Cycle Salvage led to some dope 1981 Suzuki GS400 Enkei wheels with mesh disc brakes, calipers and brake/clutch levers. ¬†I can’t overstate how generous Dean at Baltimore Cycle Salvage was. ¬†He practically gave us the parts and was fully supportive of our way outside of the box project.

Around this time we moved into Spirits Tavern’s garage on Bank Street in Upper Fells Point. ¬†We didn’t want to work outside in the winter so we made sure to add this into the budget. ¬†Here is a good spot for a pause. ¬†The following day we left to Puerto Rico for a quick winter vacation to prepare us for the wildest 2 months finishing this up. ¬†Details in following post.

The Kinetic Couch Awakens


It will be spring soon and with spring comes the annual AVAM Kinetic Sculpture Race.

Waayyyyyy back in 2011 the DC Couchsurfing group got together to raise money, design and build¬†an entry for AVAM’s Kinetic Sculpture Race (KSR). ¬†Friends used their skills to help with different aspects from fundraising, cad drawing to fabrication. ¬†We even had team members donating bikes for parts.

Couch FrameCouch

While pretty simple looking on the outside, the couch was pretty complex and took us a few months to build. ¬†This was a KSR race entry after all and it needed to be able to tackle the city by land and sea. ¬†It had to float. ¬†On top of the tubular steel frame (made from an old trampoline), we fitted a 12″ thick 3’x 6′ block of styrofoam.


Steering is pretty neat as we were trying to hide the front wheel under the coffee table the best we could.



Three people can ride at once.  Power goes from the three cranks to an idler with freewheeling gears.  This makes it so riders can rest and take turns.  Power is then transferred via a beefier farm chain to a lawnmower differential so we can get this thing to turn.


While we were off to a great start, our day ended early. ¬†We bent an axle, likely during the enthusiastic Le Man’s start, and that eventually led to a broken axle at the bearing. We packed up about a mile in and drank¬†away our sorrows in the very neighborhood Siri and I would move to a year later.

It wasn’t all a waste though. ¬†Our breakdown was spectacular enough that we won the coveted Golden Dinosaur Award that evening. Those of us who were still upright had gone to the ceremony for the free beer and were pretty well sloshed when we went up to receive our statue.


After a few years sitting in the bushes I finally have the space and tools in Baltimore to resurrect this machine. ¬†We can fix it.. we can make it better. ¬†I’ve brought it down and am announcing our 2016¬†entry. ¬†We’re hoping to find support from the local bike and couchsurfing communities.

Things¬†we’d like to accomplish:

  • Move bearings outboard to be closer to the wheels.
  • Repair broken axle.
  • User stronger wheels with better brakes (moped wheels?)
  • Re-grease cranks as they’ve sat in the elements for 5 years.
  • Possibly add derailleurs so we can have multiple gears.
  • Testing, testing, testing.


As it sits today.
