“Last summer I purchase an older tool grinder as part of a package deal with some other equipment I wanted. As luck would have it, the motor data plate is long since gone, so it has been a bit of a research project to determine a model number. After a lot of web-searching, I have finally figured out that it is a Rockwell Delta (Delta Rockwell?) model 23-505, manufactured sometime in 1945. The machine is in pretty good condition overall, although it is missing the miter gage and the coolant cup (I think I can figure out replacements for those…). More to the point, both grinding wheels are pretty well worn and need to be replaced. I found reprints of both the operator manual with parts list/drawing, and the original sales catalog for the machine. According to the literature, this grinder was equipped with 6 inch silicone wheels, 1-1/4” arbor hole, 1 inch face. One wheel was 60 grit, the other was 120. Catalog numbers for them were 1661 and 1662 respectively.
So now for the hard part: where to find replacements that fit? I have been poring over the McMaster Carr website trying to find something close, but have not really come across anything that matches all the parameters yet. I am going to contact MC tech support to see if they can help, but I can already see they are going to be pretty spendy if they have anything that will work. If any of you have other recommended sources for replacements I would appreciate the help.”
I’ve checked EBay and not found any wheels meeting all his specs, 6” x 1” with 1 1/4 inch hole. So they must be hard to find. Please find a 60mand a 120 grit wheel for him. I think he’ll need to be flexible regarding the exact material in the wheel.
