What is the best RPM for epoxy application and where do you get the motors?

I've got a Pac Bay I believe it is 9rpm. Works well for me. Opinions on this are going to vary depending on the builder. What works for me may not work for you.

I have used from 1 1/2 RPM to 9 RPM, and I tend to like the 9 a lot better. The picture I posted under Timed dryer that I built has both 9 RPM motors on it.

I like the 200 rpm setup form Flex Coat, makes for quick application of finish and I get straighter edges of finish to the blank. Not sure if you can still do it, but I was able to get just the motor and chuck and not the complete unit. I then put the rod in a dryer that is 6 rpm.

Mine runs @ 20 rpm as recommended by David Norwich of Scotland one of the finest custom rod builders in the UK.

Walt,
If you have a power wrapper, you already have the best finish motor around. With a wrapper, you can start, stop, and vary the speed of the blank as needed.
There are times, when the rod needs to be stopped, but there are times that you can spin the rod at 500 rpm to get the finish on the rod.

After finishing the rod, checking and aligning the guides, doing a double check for any sign of guide contamination and removal, I simply put the rod back on the wrapper- with cardboard under the blank to keep any finish from building up on the wrapper, and apply the finish.
After the finish is applied, and cleaned up to the builders satisfaction, the rod is moved to the dryer for overnight drying.

You can use a 1 rpm motor if you want and it will work fine. It will just take longer with the slower motor. The one thing that is nice about any finish application system is to be able to easily stop a rod at any position on command and then resume rotation on command. When you are applying finish on the edges and by the guide foot, it is very helpful to be able to completely stop the rods rotation easily.

Take care
