Just wanted to share my Acetone Vapor Bath setup.
The glass container has a 4.25" mouth opening which a standard coffee mug top fits through easily.
I merely pried the metal rim off of a portable coffee mug top to be used as a rest at the bottom. To keep it centered, I drilled 4 holes on the sides and threaded bolts with nuts though them. Once inside the jar, the bolts are turned until they each hit the sides of the jar.
For the basket, I found a metal food skimmer, removed the plastic handle and bent the loops upwards. I squished the mesh (which allows the acetone to smooth the bottom as well) until it formed somewhat of a flat surface for the prints to sit on. I then took some wire and looped it in and around the loops while making sure the top of the wire would fit inside the jar.
Next came the lid... I decided to design it to keep as much of the vapor inside while having a safety feature that wouldn't allow pressure to build up. Hence the safety BB and Mini Clothespin pressure valve was born.
I took a mini clothespin and drilled a small hole on both sides of the contacts making sure that they weren't too deep. When the BB is inside, the wood doesn't touch which ensures that pressure is on the BB. I then attached the clothespin to the top of the lid with some superglue. Once it was solidly bonded, I drilled a smaller hole through the center of the hole in which the BB sits. To make sure the clothespin had a good seal and won't break off, I hot glued around its base.
When pressure builds, the BB allows the pressure to be released rather than having it blow the lid off. This keeps the majority of the vapors inside where we want them to stay and helps prevent the Acetone from evaporating.
- I noticed people are trying to download this project... all you'll get is a slab with a photo of the jar grouped to it... figured I'd save you the time and effort.
