- I mounted a wood beer mug to a motor to spin it so that the epoxy wouldn't run while it cures

A couple of weekends ago, I went to a small Renaissance Faire event. One of the vendors was selling very nice wood mugs! They were well crafted, but expensive. It made me wonder if I could make my own.
I put together a "fail-fast" project out of scrap pine using my table-saw. After not being happy with my original finish (and getting a crack in it) I thought I would try a two-part epoxy finish. While I was at the big box store for other reasons, I saw some epoxy on clearance, so I bought it. The epoxy was pre-tinted and called "Weathered Wood".
I followed the epoxy directions and brushed it on the mug with a chip brush. Unfortunately, the epoxy ran, and made an uneven coat. Worse than that, since the epoxy had a tint in it, it's almost clear where thin, and very dark where it's thick - so uneven color as well. Frankly, I don't like how the color turned on on pine - it just looks dirty. Tests on other types of wood look much better.

After curing, I lightly sanded the mug and needed to figure out how to do a better job on a second coat.
My thought was to simply rotate the mug the entire time it was curing. I have an electric wheelchair motor, which I have used on several projects before. It's powerful, but also has excellent speed control with a small generic motor controller. amzn.to/43bLyJL
I power the whole thing off a Ryobi 18V cordless drill battery and "PowerWheels Adapter". amzn.to/3Mx7eZu
This is the same motor which I used recently to help me with a solar installation: • DIY Solar Panel Lifter.
I simply cut a piece of 1/2" plywood to a small square and drilled holes in it for the wheel bolts on the motor. I screwed a short piece of scrap pine to that and then in turn superglued the bottom of the mug to that sacrificial piece.
The mug stayed on nice and solid to the motor. I stuck a shim under the motor to get it so the mug was level.
I slowly spun the mug, then applied the epoxy to it with a chip brush. Then I left it to rotate and cure over-night.

very cool!
I built something similar for my wife a couple years ago when she wanted to epoxy mugs. She put different sizes of foam on the ends of sticks so she could just slide the holder inside the mug instead of supergluing to the bottom of it.
How do you work on the INSIDE of a mug with that design?
@@BenjaminNelsonX we weren't epoxying the inside or the lip because the resin we were using wasn't food safe and the mugs had finished insides when we bought them
Cheers!
I see Valance batteries and some transmissions
Sharp eyes would spot a Nissan Leaf gearbox.
I have all sorts of cool junk in my garage.
just run it on the battery charger! you are only burning 20W
One of the things I like about DC is how easy it is to run from a variety of sources.
This motor was already rigged up with the Ryobi battery adapter from the last project, so I just slapped a battery in there.
There are other ways to power it as well.
Please my name Napoleon Charles, would want us to really talk about a project that can skyrocket your finances and mine too
