Lap wheel

Does anyone out there have a lap wheel they are getting rid of?
I only need the wheel I can manage the stand, motor and such. I just want a second grit.

well, how flat, how big. I have a 38 inch not so flat that would make a nice coffee table. 1.29 " bore

Here's a option that worked for me and may be of interest to others.
Call your local bearing supplier and tell them you need a flat faced sprocket of whatever diameter you want. You can also buy the shaft, shaft collar, bearings and pulleys. If you looking for something in the 24" to 36" range it will be 2" thick or better. I found that to be the cheapest solution and they will pay the shipping. You of course need to be able to pick it up lol. I thought I would have to have them blanchard ground but to my surprise they are surfaced on a lathe and good enough for my needs.

If you can wait about 6 weeks I'm planning on getting some made if you want to jump in.

If you get surplus drops in larger machine shops, you'll get better price on the steel. If you buy a 4x7 sheet in 1.5 inch, it will cost you. I just bought what I found in surplus drop land. Sometimes 30 inch 1.5 inch. Sometimes 28 inch 3" thick. In my life I've worn through about six wheels down to too thin to true. I'd give you a 38 inch that can't be lathe ground. Too thin and it chatters. It could be run on a blanchard.

And max, I won't be here in July.

I am trying to imagine a worse idea than a group buy on wheel heads. Size alone will cause a crisis, thickness, then crating and shipping.. It is not a well thought through idea.

It's probably cheaper to have them made yourself. Although I would be up for shipping and crating -- probably $250-350 for that alone.

I know where I can get some sizable drops (probably) for a decent price. Otherwise a fresh 24"x24" sheet 1.5" thick is $320 and weighs 244lbs.

I don't think there are any machine shops in town that can handle the job... other than the engineering school, which I have a good connection. They have a huge water jet also (probably 10'x20' just cool), if that would help in the process.

The fabrication lab at the National High Magnetic Field Laboratory down the street is also droolworthy.....

Pete is sending me a copy of the Hot Glass Info Exchange so I'll keep you updated on this journey

Note: I'll definitely be completing one first before I start taking orders!

24x 24? That,s not a sheet.

I was thinking a 4ft x 7 ft sheet of the same material. The only way you save a dime is to use the whole sheet, all at once. All processed the same so the lathe/ cutting tool set up needs no adjustments at all.

You're talking an expensive wheel.

a 4 ft x 8 ft sheet is $1764. Which would make 12 two-foot wheels. Which would make each wheel about $150 or half the price of buying it cut ($320).

Trying to sell 12 wheels though, hah!

I bet I can get decent drops in the $200-250 range. They do a lot of bridges and steel-frame buildings. So getting them to cut up a big drop ain't no thang, they had some nice 2ft x 6 or 8ft last time I was there.

All the sheets I bought were 4x7 sheets which I always thought odd.
But have it clear faced ( machine shop speak) both sides, chamfered edge and center bored to 1.29.

You'll be a lot happier with a 30 inch wheel over a 24. My 38's were my favorites. That took a 2HP motor.
