After taking the course offered by photo engineer, I decided to try building a small tabletop coating machine that I could use to coat paper and film up to 16" wide. I received all the machined parts yesterday from the local machine shop and plan to start working on construction this weekend. I imagine that there will be some tweaking required to get it to work consistently, but I believe I have a sound design. It will be a one shot deal, in that a single pull will coat a substrate up to 16x20.
I hope to have it working well enough by the end of the winter to use for coating Photo Engineers emulsions. If not, well.... I'll have some really cool looking stainless steel scraps that will function as very effective paper weights....
