I almost finished a hollow ground bowie blade on my Burr King and realized that my 8" wheel was in trouble. On the right side of the wheel the rubber on about 1/3 of the wheel is missing up to about 1/4" wide and about 1/8" deep. Can I get this wheel repaired somehow or do I need to get it re-rubbered (is that the word:confused: ) Also can anyone suggest someone who can repair or re-rubber this wheel for me. Thanks for the help. Dave
 
Hi Dave
You can dress the face of your contact wheel yourself. Glue a piece ( 12" ) of fresh 60 grit belt to a piece of timber and using your rest run it across the face of the wheel while its running. Make sure you are grinding parallel to your axle. When you have removed all the wear wrap the face of the wheel in 3 or for layers of masking tape (2" wide). This will protect the surface of your wheel in the future. As the tape wears replace it.
I am asuming your contact wheel is direct drive or belt driven off the motor. Hope this helps

Hi Dave

I haven't had to do this yet, because I don't do much hollow grinding. There are places that will recoat yur wheel, but it can be fairly pricey. The "do it yourself" dressing that peter mentions sounds like a great idea. If you are removing as much as 1/8 of an inch, you may find that the radius is s lightly different from the groove you've already ground on that knife.

You might also want to consider a second wheel - one reserved just for hollow grinding ( maybe a smooth wheel) and one reserved for hogging, profiling, working corners and all the other things that would wear a wheel quickly.

No offense to anyone, but I'd recomend against trying to true it yourself. You will end up with an out of balance wheel that is much smaller. I know others say they do this all the time, but maybe vibration to them is different than to me. I won't tolerate it in a grinder my life depends on.

Call these people and they will recover your wheel better than it was stock.

You have to be very careful when you drift the belt off to one side that you don't hit the exposed edge with the blade blank.
Your eyes have to watch several things in close proximity at once to keep bad things from happening.
 
Good advice from Mike Hull. I've had Contact Rubber recover several wheels for me and had them true up one. All the work they've done for me has been outstanding.
 
Hey Rob, how's everything going. Good I hope. Thanks for the info everyone. I'm not sure how this damage happened but it's definately taught me to be much more careful and attentive when grinding, especially when just hogging off steel. I've been meaning to get a 10" wheel anyway so maybe I'll do everything at one time.
