Probably not the gear motor you have said was spendy, but just the light
kind off a backyard rotisserie. With proper support, and minimal
resistance, should do smaller amounts of meat. Going to buy the next
rotisserie I see and build a small one. But it will be enclosed, not open
like the one Ig posted.

Looks like a nice, good motor from a chicken rotisserie. Doubtfully it
will turn a 50 lb pig. I bought this motor on eBay:

It is 1/10 HP and I think that it could turn a 50lb pig at 4 RPM after
reduction. I can make sprockets with CNC, so making a reducer should be
easy.

I don't think you really want to turn a pig on a spit more than 1 RPM.
The latest Surpluscenter catalog just arrived in the mail and I see a
motor that looks promising, item 5-1741 12VDC, 1.6 RPM, 78 in-lb torque,
$18.99. Couple to the spit with 1.6:1 drive ratio or so. It would seem
to have enough torque to handle 10# of imbalance 12" out from the spit,
which is more than you're likely to see on one of those small pigs.
