Re: sewing machine advice
Is the TacSew model number T111-155? If so, apparently it is similar to the Singer 111W155 which is a compound (both bottom-feed also called drop-feed, and top-feed also called needle feed) walking foot (alternating pressure-foot) sewing machine.
As for pictures, upload them to phtobucket.com and post the link here.
Running a machine with a motor below the machine has the advantage of being able to change out what is probably a clutch motor for a servo motor that gives much more control.
