I have a 10" diameter 2" wide CRC serrated contact wheel that is showing excessive wear on the left side.
It has a gap at the extreme left that is is 3/64 and tapers across the wheel for 3/4".
I don't know how it could be wearing.Is this something I can fix or am I going to have to have it re-tired?
I would appreciate any help.

Thanks
 
If it was mine, I'd send it to be recovered. It's very hard to get one of those trued up playing with it with sandpaper on a piece of barstock, files, etc.
This place is very good. They do excellent work.

Be very careful sending anything to Chicago Rubber corp. :eek: :barf:
 
Man, those guys have a 30 inch contact wheel! :D I think I'm gonna have to start thinking about building a grinder again...
 
What's wrong with Chicago Rubber? They just trued up my 10" contact wheel for my Burr King, cost was $30.00 ,even got to watch them do it.

It's a very long story, but I sent them a 10" Burr King wheel and they not only sent it back out of round, and with run out side to side, but had it three weeks to accomplish that. When I returned it to them, they had it another month, and sent it back so badly damaged as to be almost unbelievable, like I'd never notice the new arbor bushing they welded in to try to compensate for eggholing my original one, and turning the built in hub off the inside of the rim in an attempt to cover up the very sheety welding job, full of blow holes etc. I could go on for quite some time with the rest of the problems, but maybe you get the idea.
The biggest problem was, they knew what they did, and tried to pass it off on my like I was some bozo, and when I called them on it, they just shrugged. They couldn't have cared less.
They ended up buying me a new 10" from Tru Grit and having John direct ship it to me.
I cut the old one up for rubbing blocks as they didn't even want it back.
Never again! :eek: :barf:
 
I talked to CRCs customer service rep and made arrangements to return my wheel.
I'm going to ship it to them Monday.
I'll let you know how it turns out.
 
If you want to get a solid wheel, instead of continuing with the serrated, or get higher or lower durometer rubber(harder, or softer), now's the time. It won't cost anymore at this point. :eek: :D
Good luck!
 
What are the advantages and disadvantages of solid and serrated?
The wheel I have now is 70 duro.Any reasons to change?
I still have plenty of rubber left on this wheel,so his suggestion was to regrind and true it up.
 
Solid gives a better finish than serrated, but serrated supposedly hogs material faster, though that's not a concern with me. I can profile a blade from barstock faster on a solid contact wheel, that I can on a bandsaw.

It's the finish that does concern me, and that's why I use solid wheels. They also run with less vibration than serrated.

70 durometer is fine, but you can get slightly better finishes the higher you go, but it becomes a trade off. The 70 is easier to get a bevel going, like using padded grinding belts(norton), but the higher duro's(80-90) last longer, but can be less forgiving. I bought a 14", 90 duro wheel from CRC awhile back, and it's HARD. :eek: ;)
I think a 70 is fine for most applications, but you would be the better judge for your uses. :)
