When replacing the expando drums is there anyway to just get new drums to add to this equipment? When i search expando drums it looks like I have to buy an entire new set up. What grits and size expando drums should I get?

You can buy loose expando drums. The belts are sold separately. They come in grit sizes from around 90 grit up to 600 grit in silicon carbide. In diamond they go way up into the thousands grit sizes.

As stated earlier, if you're just getting started in lapidary, start out with the cheaper silicon carbide belts. Get at least 2 of each grit size. They will wear out in time.

When a 600 grit belt is worn out, don't throw it away. It'll still contain broken down grit & makes an excellent pre-polish belt.

I'll see if I can find links to expando drums & belts for you.

These are from Kingsley North. A reputable dealer that many of us buy from. You can access their complete catalog online, or they'll send you a hard copy catalog if you wish.

Hi K

After looking at the pictures it looks to me that the wheel on the right side is a silicon carbide grinding wheel. If it was taken care of it might have a lot of life left in it.

The wheel on the left does look like an expando type but of an odd size. You probally well need to replace it unless your other machines have wheels on them also. If they do please show pictures. If not then an new expando would be the way to go. The first thing that you need to know is your shaft size. From the picts you have enough room for a 6 or 8 inch wheel. Width will probally deside.

There are many ways to do it, & I'm sure others will tell you their methods. For mine I have an old 2 gallon garden sprayer sitting on a shelf above my machines. I just fill it with water & let gravity do the rest. If I need a little extra water, I just give the sprayer a couple of pumps.

Shawn: I am about to upload picture of the two other grinder/polishers I have. Using parts from one to make the other better is a great idea! Let me know what you think when I upload the pictures.

Jake: Thank you very much! Sounds simple enough!

OK

Now I see. Those machines are not junk so keep them. My thought is you want to get something up and running as quick/cheep as you can.

So I would work on the first machine if you have turned it on and it does run. If so then I think you need you need to work on making the left wheel a new and improved expando type wheel. As said before the sanding/polishing belts come in many grits and 1 wheel will get you to the point of final polish. Now do any of your machines look like polishers?

It doesn't look like I have a polisher at the moment. But the guy I am working for is bringing more equipment Sunday. Do you think I can use one of the wheels from one of the other machines to use as a new and improved expando wheel or do I need to buy a new one?
