What kind of grinding wheel is used to make the donut beads outer edge? I've found the 1" wide concave grinding wheels and they appear to be too wide. For a couple donuts, one could just do a double sided cab. I'm looking for a setup to be able to do a bunch of uniform size donut beads.

I'll bet you can't stop at just one saw . . .

the link belts work great. I've used them on the old HP saws with the pillow block bearings on the outside. If the main belt breaks, one has to disassemble all the bearings and ruin the alignment to change the belt.

How does one polish 6" x 6" slabs of UT septarian nodules? Normally, I would use the vibrating laps with grit. I have concern the grit will cause undercutting. How will the calcite handle the heat of high speed dry sanding?

Use a thick wall bucket for the shop vac bucket head. The cheap buckets from Lowes, Home Depot, or Ace Hardware will collapse.

I've used the same shop vac bucket head for 3 to 4 years now and haven't had any problems. I run 7 saws and try to do more than a 1000 cuts a year. The shop vac bucket head has kept up with my needs. It saves a lot of time.

Saddle Mtn has petrified wood. Go to Vantage and see the Gingko Petrified Forest Interpretive Center. www.parks.wa.gov/288/Ginkgo-Petrified-Forest Call first to make sure they are open. There is also a hiking trail that winds around several large logs. The logs are gated in. Take water. Also, see Bill Rose's rock shop in Vantage. www.roadsideamerica.com/story/22439 Call first to make sure they are open.

You're retired now . . . move the saw to the top of the list. The other items can wait.

The 3450 is too fast for lapidary purposes. I also would not attempt jewelry work at that speed either.

I use three vibrating flat laps to sand and polish. I would recommend staying away from aluminum pans as they wear and can dish. Especially with heavy rock such as bookends. I use a thick plastic sheet to cover the lap and hold it in place with clothes pins. This eliminates any splash. The plastic also minimizes evaporation so the pan doesn't run dry. I run them 24/7 and check them 3 or 4 times a day. Ask around and look for estate sales for the best deals.

We run 9 to 11 tumbler barrels at a time. Three of those are Lortone. My wife loves the Lortone barrels for ease of opening and sealing. Leaking is not an issue with the Lortone barrels.
