There is a glass grinder for sale near me, would it be a good start for a grinder or would I be better off making my own?
 
Just about any belt grinder can be used for a glass grinder. The type of belts used makes the difference., Silicon carbide belts are often used. Is this a 2X 48" or a 2X72" size?It doesn't seem to have either a platen or table But sure, you can use the usual metal grinding belts on it for metal grinding slack belt work but not much else. It could be very useable is you had a regular 2X72 for handle work. Frank

Looks like it was designed as a wet grinder with the bottom being submerged. Depending on the price, you could canibalize the parts and make your own with a bit of modification. If you have access to a welder you could fab up a quick frame out of some scrap steel and transfer the parts over. If it was near me I would at least go look at it and see the condition.

As it sits there may not be much value as a knife grinder, but it has all the parts to become something more. Just have to look at it the right way.

It appears to be a 2 x72? This could be a great start? If the water trough system man be a good add on. It looks like a rubber contact wheel of some size and the bottom and bracket looks like you could built a work rest and possibly a flat Platen on it?

Frank may be correct as far as using it for slack belt handle contouring and I would add profiling if you can build a work table on that bracket?

Give us some more info? As mentioned.

Size of belt?
Variable speed or not?
HP of motor?
Kind of belts coming with? Looks like at least 30 belts?
And if you can dicker with the seller on price?
Where do you live?

Wow, it's so early in the morning I didn't even see the boxes of belts sitting there!
I don't see it being worth a high price for a grinder with such limited potential as is, though. I think price is the most valuable information as I would probably throw no more than $300 bucks IF all of the variables lined up.
At least 3/4 horse motor(ie: stronger than a 2x42 craftsman)
Ability to modify said work table/flat platen
Vs motor would increase price but I don't see it
Size of belt with 2x72 being ideal. Check availability and price of off size belts prior to purchase.
May not be a deal in the long run once these factors are added up. Definitely do your homework.

With some modifications, a glass wet grinder can make a great knife wet grinder. They normally have much longer and wider belts than a 2X72, and are often 3X132. Many are 3Ph. Motors run in the 1HP size.

Get the specs on that grinder....but ( unless it was roached out) if it was for sale in my area, I would take it in a heartbeat for $300....especially with a stack of belts.

That is most certainly a 4 X 106. I have one like it that was made between 1937 and 1964. It has (had) a solenoid valve that sprays water on the belt. If the upper and lower wheels are worn it won't track properly. I resurfaced both wheels using some 1/8" rubber matting. If the belts are old they will break at the splice ln short order.

I'd use the hell out of that thing!
 
It has a 1hp baldor motor, single speed 1725rpm, 4" x 106" belts. He wants $300 for it, haven't tried negotiating yet. The model number is CRL2200RP. It appears to be missing the "roller platen" which I don't think would be of much use to me anyways and the solenoid for the water system. I might let it sit a day or two and shoot him an offer, the ad makes it seem like he's not certain what It's worth.

See if you can find out a date of MFG on the boxes of belts and price those w x 106" at www.trugrit.com Ebay etc.

I like the idea of a wet grinder since I grind after HT. Even dry the machine may make a great handle sculptor?

Truth is, he probably doesn't know what it is worth and probably hasn't had much interest for it. Like Laurence said, price out the belts to see the value. If it works well and you can get belts at a decent price it would be worth having if you can do a few mods to it. I'm sure getting the wet system back up and running wouldn't be too difficult if you wanted it.
Let us know how it goes and try to get us some more pictures of it!
