Research sand casting. The pan should be a relatively easy project, just need to get a few casting supplies.

Mine just has three 1/4" pieces of weather stripping type foam.

Does your unit have the set screws on the side that clamps the pan in?

If you are using a two speed evaporative cooler type motor, the low speed is around 1120 RPM which would give you the 14 RPM you are seeing. A 9" pully would put it around 17 RPM, to get in the 25 RPM range use a 6" pulley.
Hope this helps. Tim

Throwing your numbers in excel, your tumbler should be turning ~21 RPM, if you go with a 9" 2nd pulley you would be around 26 RPM. Assuming it is a 1750 RPM motor.

When mohs and I stopped for pizza in Tonopah our server was a member of the Otteson clan. I'll be driving that way again in a few weeks, maybe I can pony up and get my 2 hours in their tailings pile, meet a TV star. It has the flavor of the staged reality TV crisis and conflict drama, but the mining and discovery is still fun. I have Prime as part of my cell service, watched the first 2 episodes so far. I am entertained. Next trip to Tonopah try the Tonopah Brewing Co. Good BBQ and craft beer at good price, www.tonopahbrewing.com/

From my personal experience, Vib laps are not something that you can leave unintended for long period of times, the pans will dry out (At least in Az). As far as the three wire cord, it never hurts to have the extra safety of the Ground wire since will be working with water. I generally go to HD and buy short extension cords and cut them down as needed.
Good luck.

Do you have saw marks on the slab? If not, step 1 is very aggressive. I went from saw to dry sand with worn out 600, then step 3.

I have polished several brazillian agate slabs on an 8" expando with a worn out 600 grit sc belt at high speeds, worked real well. Just do it in a well ventilated area.

I always polish my 'Onyx' with a dry buffing wheel and some Zamm, works great for softer rocks. Just use in a well ventilated area, I hear it can be bad for your lungs.

I am thinking these are Tabu Tabu Jasper. These next 2 pics are from the same piece of rough. One end was all brecciated red and slowly morphed to what you see in the 2nd picture. I had a 3rd pic where the red was all gone but that shot was blurry so I didn't include it. I don't think I have ever seen a piece of rough with such a pronounced change like this where both patterns are interesting. Usually you only see interesting pattern give way to uninteresting host rock. No idea if this has a name. IMG_4947 by Shiny Objects, on Flickr IMG_4948 by Shiny Objects, on Flickr

Nice looking little saw, originally I was thinking Beacon Star, could not find one close online. Maybe Tony or Lee#2 might have a clue. Good luck, if you find out, please post manufacturer's name.
