Disk Sanding Question

[Richard Marsh]

I suppose this ranks in the category that if I have to ask, it probably isn't safe, but I will ask anyway. I have a 10" aluminum disk made for my table saw that uses PSA sandpaper (max speed 5800 rpm). Would it be safe to use this with my oneway talon chuck with jaws expanding within the arbor hole?
Thanks,
Richard

Richard, I don't think I've ever seen that done. I suppose it would be safe as long as there's a secure connection. For very little time and expense, you could create a sanding disc by mounting smooth flat material to a faceplate. A lamination of two layers of 3/4" MDF works well. If you seal the MDF, the sanding disc will stick better and you won't be restricted to the 10" size.

Most table saw arbors are 5/8 inch, and that seems a bit small for a chuck to expand into. If it fits and goes flush against the jaws of your chuck, then it should be fairly stable. Like Malcolm says, it might be easier to make a specialized one for your lathe.

+1 for easy to make. A 15-3/4" disc of 3/4" particle board on a dedicated faceplate works well. As mentioned, seal with a coat or two of varnish.
