From Raymond…
I saw these boards a while back after seeing a wooden build someone else had done. I loved the concept and ended up picking one up to tinker with.
I don’t have a 3D printer, and don’t have the right woodworking tools, so I ended up going a different direction; these boards are perfect for potting in resin! With no cabling for power or data, there’s no reason not to embed them in a block of resin.
I Embedded one of these E-Z Lok inserts for tap threading. I sealed the upper end with Scotch tape to prevent the threading from being filled with resin. (Filling with wax might have worked better, but it did the job)
I poured the resin in two stages; front layer then positioned the board face down on the cured first layer and poured the second layer.
Turns out there are reasons not to pot these boards in resin; you run the risk of putting the NFC chip out of range of your phone if you bury the boards in too thick a layer. I had to sand down the surface until I could get the board to synch up with my phone’s NFC transmitter again.
The resin kit I bought. Easy to find on Amazon, and easy to use.
- Environmental Technology 8-Ounce Kit Casting’ Craft Casting Epoxy, Clear
- Search Amazon for “Easycast Clear Casting Epoxy” to shop around
A test tap handle I made cause I had the materials and molds.
After sanding and polishing on my buffing wheel.The “finished” handle. If you look, you can see where the tape came up a bit on the threaded insert, and some imperfections are visible on the backside.
I also oopsed and used too large a mold; I’ll need to trim it down and re-sand/polish if I want to use large tap handles on the other two taps.
All told I’m moderately pleased with how this came out. I’ll probably build another one at some point, using a different mounting method
