I recently acquired a Stanley No. 7, and while the base is not too far out of flat, it needs a bit of work. Being lazy, I was wondering if I could flatten it, at least for the first pass, on a 6/89 belt sander, running either 220 grit, or 120 zirconium alumna. If so, this would save condierable effort and time. Has anyone tried this? My belts are edge joined, not overlap joined.
Thanks for the help.
