Steel Sanding Plates by Shopsmith True?
I am going to make a stationary disc sander with quick change discs. I am considering using Shopsmith steel sanding plates, but don’t know how good they are. Do they run true? They are pretty thin, but if they work well, it would simplify my design.
Thanks

Strangely enough they run pretty true, I get equal loading all the way around and very little vibration. They mike out to .120 thick X 12"Dia. 5/8 arbor hole X 2 3/13" deep. The plate I have is the flat version, not the crowned version. By the way you can make it double sided if you build a clever table top.
Work Safe, Count to 10 when your done for the day !!

I Haven't used mine in years. Having purchased it in 1984, I can't remember the runout, but it is substantial in my opinion. I contacted them when I got it; they said it wasn't designed to run true. But rather, if you run the stock back and forth using the miter gauge, it would "average out" and the stock would be square to the miter gauge, based on the portion of the disc running closest to the work. I could never use mine for accurate work.
I've got both the old style aluminum and the new steel disc.. never had any problems with either one.
The new steel disc is bolted on to a machined hub, so I'd expect it to be very accurate.
Maybe the other guy's got dropped too many times in shipping?
Mine is made out of steel. But I believe the stresses induced during welding the plate to the collar left it not perpendicular to the centerline of the hub.
<!---->We were created for more than shaping wood!<!---->
Strange.. Maybe they've changed the design since then. Mine has 4 screws that hold it to the hub. I don't know.. I don't have any complaints.
SS has got a sale going right now where you get 2 discs and a bunch of paper for 25 or 30% off.. maybe you guys should split one.
I better go check mine out. I responded purely from memory from 1984. I do know I could not count on getting square joints or square chisel/plane irons when I used it to sharpen. So I simply quit using it. I may have inadvertently posted a false statement about the disc being welded to the hub. I so remember a few conversations with SS. I was told to run the piece back and forth while clamped to the miter gauge so that any high spot on the disc would cut each fiber of wood during the process.Now that you mention it, I seem to recall some screws in the face as well. ,I will check, but mine has still got the original sand paper disc on it.GREG-->•••••••
