Pup: if you do end up putting a full inch wide stone on your block can you tell us how it runs and post up a few pictures?
Finally I got the 6"x1"x1"AH wheels in 60 & 80 grit. I decided not to get Norton wheels even though I have a few wheels by them and many online swear by them. Why? Because they're now made in China

I went with Camel Grinding Wheels (CGW), made in Israel. I figured I give them a try over the Norton imports. Cost each about $20 with shipping from Suncoast Precision Tools on ebay. Also on ebay from Drill Spot I ordered two sets of 1" to 1/2" Reducer bushings for $6 for both sets.


Both wheels installed, I noticed that the reducer bushings did not have a snug fit around the 1/2" diameter shaft. The bushings ID are 10 thousands larger. I had to by eye center the wheels the best I could with minimal runout. When I get my lathe up and running, I'll make my own. The covers went on with no issues as far as the outside washer hitting. There's an 1/8" gap on both outsides of the grinder and 3/32" gap on the inside.




Fired it up and the wheels ran with no problems, no hesitation or slow start up. The left guard was cupped in so I had to straigten/flatten it out in the vise because the wheel would hit a bit from the inboard washer being out of true. After fixing that minor issue the wheel does wobble more so than the right one. Another lathe project at a later point. After installing the left cover I noticed the grinder took a hit at the tool rest area. In the second picture above you can see the inner side cover leaning to the right, so the tool rest now won't sit square to the wheel. Also two cracks in the casting near the tool rest. Guess I'll be shopping for a side cover for this grinder. I had to put a small washer at the bottom screw behind the cover so it won't distort it.
Here's a video of it running with the two new grinding wheels. Hope this helps any one thinking of installing 1" wide wheels and thanks all for the great info here.

Um, ah.....does any one know how to embed a video hare. If not it'll just be a link to my Photobucket account. Thanks again.
