I need to replace the top wheel of my flat platten. The rubber came dry rotted and came off. I need one that is 1.5 inches. Everything that I have found is either 2 or 3 inches. Does anyone know where I might be able to do d one that is 1.5 inches?

Thanks
Mike

I fixed the wording for you.


First, you need to tell us what type platen and grinder you have. They are not all the same.

Second, why can't you use the standard 2" wheels. They are sold by most every grinder maker and knife parts supplier as well as industrial suppliers.

Last, the 1.5" wheels should be available from an industrial supplier like McMaster-Carr, or can be made by anyone with a metal lathe. If you had a good wood lathe, you could probably turn the aluminum wheels on that. Oregon Blade Maker would probably make you a set - www.oregonblademaker.com
 
It doesn't have a manufacturer plate on it although the machine was definitely not a garage project. The platten on the other hand probably was. If I go to a 2 inch I would have to cut the flat some but then I am worried my geometry would be off and I would get convex grinds.

That's an odd duck. I would take this as an opportunity to replace that entire platen with an adjustable one. The whole kit, wheels, platen, platen mount, from Oregon blade maker is relatively inexpensive.

It wouldn't hurt


Different wheels mount differently

If he wants direct replacement swap outs, it would actually be helpful.

He posted a pict? Did it help :rolleyes:

1.5" contact wheels are not common and have to be ordered for that size.
 
As far as recovering goes, I see that mentioned here often, but I just got quotes on multiple wheel sizes and they were all the same or near the same as buying new wheels.

So how much for a 10"?
 
Adam I made a spreadsheet on my work computer I'll check tomorrow.

Just because he posted a useless photo to ID the grinder doesn't mean that a grinder ID is useless.
I was / am thinking if it's that old, it may be a square wheel = and those have a completely different mounting system than the typical put a bolt through a bearing mount.
 
After work today I can post a pic of the grinder. I do like the idea of a new platten but would rather just get a wheel.

I didn't get a 10" quoted. An 8" would be $96 and a 14" $196, and given the sizes/prices I got a 10" would be right about $130.

When you can get this: http://www.ebay.com/itm/2-x72-Belt-Grinder-Rubber-Contact-Wheel-250mm-10-Knife-Making-Contact-Wheel-/201700652559?hash=item2ef64bb60f:g:iqoAAOSwr7ZW8dRi for $160 shipped with new bearings.

I have 3 wheels from this seller. Two 3" wheels and a 6". They are excellent. Balanced well, and the spacer between the bearings is an excellent addition. You can crank your axle bolt down tight without any impingement on the inner races.

I got these quotes because I was going to machine a bunch of steel wheels and have them covered if covering was less expensive than this. Possibly to sell. But the covering prices are just too close to cost of a new wheel to make sense.

It may be slightly cheaper to have a large wheel recovered than buying new, if your bearings are good. Also the prices I got were for covering bare metal wheels, and didn't include removing old rubber so an actual recovering might be slightly more. Then there's shipping back and forth.

2.5" to 3" was $50-$60
4" to 6" was $60-$75
8" - $96 (smooth)
14" - $180 smooth, $196 treaded

This was from Contact Rubber. I also got quotes from Conestogo Rubber, they were higher.
 
Thank you for the pricing info on recovering a wheel - just as I expected, by the time shipping is included, a new wheel isn't much more.

These new over seas wheels people are bringing in really has dropped the price.

When I started a 10" wheel was over $300

I bought my first wheel about 10 years ago (actually getting going making knives has been a long road lol) I remember seeing everything out there being $300+ except the Grizzly wheel, which required machining if you wanted bearings in the wheel. So I bought one of those for I think about $75.



I'd still like to try casting my own rubber around a hub I've made myself. But the chinese wheels have made that almost moot. So first I'll try castable rubber as a knife handle and see how that works out.
