SWMBO finally let me have my Unisaw (30" Biesemeyer, left-tilt, WAHOO!)
When I got it unpacked, main table was out .027". Ouch. Delta promtly
sent me another. Only .005" out in a single place, but otherwise ok.
When I attached the extention table to the left, it sagged--almost
.030"--no matter how I tried to tweek it. Didn't want to send it all
back again, so I shimmed between the main and extension tables.
Here's the quandry: I didn't want to cut up a feeler gage to shim, so I
used a doubled piece of kitchen foil. Sag solved. The entire table is
as flat as my singing. But is aluminum foil ok? Am I looking at a
problem with aluminum oxidization down the road affecting the iron? Or
any other problem? Should I go back and use a feeler gage shim instead?
Thanks very much!
