My 8" contact wheel has a problem, the rubber portion has become "unglued" in a section of it. The result is that portion is slung out with centrifugal force and it is like using an out of round wheel. No good!
Can it be reglued? I doubt it, as it screams.
I was told that Bader may be able to repair it (my grinder is a Wilton Square Wheel, single speed screamer).
The bearings and metal wheel seem to be perfectly fine.
Or is there another place that you recommend?
Or, do I need to replace it, and where is the best place to buy one?
I definately want a serrated wheel, like the one I have. What is the difference between 50 durometer and 90 durometer?
Thanks in advance!

Why serated again? Serated wheels were made for course grinding with heavy belts. A smooth wheel will do a better job for you unless you are using two.
 
Hmmm, I only have one grinder, and it was recommended that a smooth wheel would give an annoying bump where the seam is on some belts like the 3m engineered abrasives belts.
I thought serrated wheels would also give longer belt life.
I have never used a smooth wheel and have so it seemed that serrated was the best way to go.
Do you disagree?
Thanks for the replies so far. Any more info is appreciated.
Thanks, Dan

Hi Dan: I think a smooth wheel will give you a better feel than a serrated wheel. And, a smooth wheel is better able to handle finishing work than a serrated wheel. Also, a smooth wheel is easier to re-dress freehand, which you will need to do at some point. As to bumping, there is about a 50/50 chance the splice will end up riding on a serration, so I don't see that as a consideration. If I was only given one hardness of wheel, it would be 70 durometer.

Just my opinion....Good luck, have fun.
 
check out the Sunray website. I've bought two wheels, an 8" and a 10" from them for my ancient pre-Wilton Square Wheel, and gotten good quick service. Their prices are great, especially compared to Wilton's absurd pricing.
 
Contact rubber , $95.00 to re-tire a wheel . They are good folks and your wheel will be balanced . I bought a new wheel , hub and all for $235.00 . I use the serrated for the hard profile grinding and the smooth for the bevel grinding . 70 duro on the serrated and 60 on the smooth
 
I have a 90 here in the Shop and it is hard as a rock! Way harder than a car tire. Bumps like hell!

Serrated is good for hogging. All the extra noise and vibration will get to you after years of use.

A smooth 70 doesn't bump. It's like riding in a Roll's compared to a buck board. Especially if you have a 90-d serrated! A spare wheel in 90 is great for shaping the blank from the bar. It's fast. Terrible for grinding the blade though.

I now have apx. 12 or more contact wheels. Start adding to your collection. It will help you in the long run.

Another concideration if you buy a new wheel is one larger than 8" It will allow you more freedom in the grind to thickness thing. Mine is a smooth 10" but I also do flat grinding. Frank
 
i like finishing with the gator belts as they dont have any bump to them

and as far as building a collection of wheels i only have liek 6 but am thinking about settign up a KMG to run 3 inch wide wheels
