Shopsmith Forums

Well I know 2008 was a long time ago, but at that time the MFG was Amana ...

Certainly could be someone else by this point.

If Doug says CMT, it is probably CMT. Doug is in a position "to know" and has no reason to tell us otherwise. But, where did Doug say this?

One clue that makes me think it may be CMT now rather than Amana is the little semicircular notch in the bore on CMT blades. Same as on my Shopsmith blades. I don't see that on Amana blades. You can see it on my Shopsmith blade in the photo below.

My Infinity blades have the same laser mark from cutting that hole.

Ed,
I'm referring to the notch at the end of the arrow. I don't see that on Infinity blades on their website.

This is just a guess but could the notch be intended to key an adapter so the blade can be used on a 5/8 inch arbor?

I just got back in from some hours in the shop but I'll go get a blade and take a picture. The hole is when the laser cuts the hole, if the holes are punched you will not see this. That is a good sign on the shopsmith blades.

Need a coffee to warm up with first but I'll try to get it done soon. It was just 42 in the shop when I first went out, turned the heater on, came back in and did a few things, by then it was about 47. When I was near the end of my time out there it was 58. Turned it off for the last half hour and it was down to 54 when I left. Just 9 degrees out and lots of wind, gusts into the plus 30mph range.

Not the best picture but if you look close you can see it. It is more of an arc then a circle.

From the web site:

"Laser-Cut Arbor Hole

In the photo above, you’ll notice that the arbor hole on the Super General features a small bump, or nipple, as we call it. This is proof that the arbor hole is cut with a laser instead of being stamped which can distort the saw plate. Cutting out the hole with a laser not only guarantees maximum accuracy with less runout, but it also hardens the edges of the arbor hole for longer life."

Interesting! I think that cutout on the Infinity looks a little different than the cutout on the Shopsmith blades I have, which look identical to the cutout on the CMT blades I looked at on line. And I don't see any on the Amana blades. Although maybe I just need to see a better photo of one.
