Don,
if your equipment is already wired for 110 then I would leave them
alone. Typically 220V would be used when your equipment is rated
2-3HP or above. Your TS is probably 1 1/2 HP and could be run on
either 110 or 220 but, as I said, there is marginal benefit to wiring
the 1 1/2 HP motor to 220.

Hey Tom,
I think the operative factor here is that he's setting up new. When I
put my power in, I figured there was so little in the way of extra
time/energy/expense to installing 220 that it didn't make sense _not_
to do it. For my one-man shop, one run of 220 around the baseboard,
then about 15 minutes per machine to change motor wiring and I'm done.
Lotta benefit for little work. However, If I had an existing shop
with _only_ 110, I'm not sure I'd have bothered to run an extra line,
figuring the occasional tripped breaker and the "110 is less powerful
under load" argument wouldn't justify the effort.

New construction is just so much easier than retrofitting, y'know?

Whoops, my mistake. I thought this was an existing building (I'm
embarrassed to say I took his comment about building a doghouse
literally). You are absolutely right, if I were building a new
workshop I would put 220 conduit in the ceiling or flooring so I could
direct wire any new equipment I installed. The 220 could be split to
2 x 110 circuits or a single 220 circuit. After using a 3HP TS I
could NEVER go back to something running on 110...

Like Mike said, anything worth doing is worth overdoing...
