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!

Pretty much all the crush happens when tighten the bolts. In 5 years my
tables are still level.

Don't use paper nor masking tape as a shim. Installing extension tables puts
a lot of pressure on whatever is used. Paper, especially the crepe paper and
adhesive layer in masking tape will crush over time and the alignment will
be out again. Aluminum could flow over time but it is a better choice than a
paper product. Aluminum soda or beer cans could be used, or brass shim
stock.

Home Depot has brass shim stock.

Many have used and recomend masking tape.

That amount that it crushes tends to not be much at all and will most likely
show when tightening the bolts. IIRC the manufacturers even suggest doing
this for the table extensions.
