To bad it's so far away. I'd buy it.

I do not know if you can cut large pieces of glass with that.
Maybe a maximum size of 25 inches wide x 25 inches heigh.

But what do I know?...

That set up looks more like it was used for glassware or engraving star bursts on small bevels. Probably also why there are so few wheels.

I may be able to get this for the price of crating shipping 1000.00. Anybody think it's worth it?

[erik winkler]

I have seriuous doubts......
But if there is nothing else to get there, how is your friend pat doing with his brilliant cutting rig?
Maybe he can help you out here and give you/us some advise.

My question is, how small a wheel can be put on it and still clear the fairly large looking bearings.

1) In fact, looking at Rich Samsel's cutting lathe as well as Pat's, I have the same question, and have had for awhile, regarding their respective setups. Rich tells me that despite the trade-offs, he does like the small wheels (cost+tight curves) he can use with this type of lathe (as opposed to Stuart Norton type of lathe), but I don't rightfully see how the glass clears the bearing housing when using small wheels. It can't from what I can figure.

2) Also, (and this is not in respect to any particular machine) not being very mechanically minded, I would like to understand the physics of what holds the shaft in place. Is it simply the belt drive that keeps it locked in place, when coupled by the stationary bearings not allowing it to move against the opposite axis?

Being able to actually see Dave's equipment on his new (lovely!!!) film has helped to answer a lot of questions that I have had.
The thing that has made me continually perplexed is that Rich Samsel once told me that he can use smaller (therefore less expensive, when it comes to diamond composition) wheels than you can use on the Norton and Smith type of machine and I just don't really see that.

It looks to me like this Craigs List machine can only work on small pieces of glass unless the wheel is larger than about 6-7". If I am right (???), that would make for about a 1.5+" diameter punty (at 1/8" depth)...or something like that.....Hmmmmm.......that may be a bit large if that is the smallest punty it can go.....

Maybe I am wanting to think that a smaller wheels is neccessary for certain things than I thought, as I now can see that Dave seems to have lots of rather large wheels on his wall. Still, doesn't the diameter of the wheel correspond directly to the tightness/curvature of the cut that can reasonably be made with it?

Aaahhhhh....."babbit" bearings with pressure fed grease pots to keep them from burning up. Hey, I'm just a girlie-girl. You guys seem to come out of the womb knowing all this stuff.
