What's your model of industrial sewing machine?
Depending on your model I'd be more inclined to spend the $$ to fix the industrial machine. If I understood correctly, you got bird nesting on the bottom thread and the needle bar somehow got bent?
A new needle bar shouldn't be more than $10 and it sounds like you need to check your timing and watch your tension adjustment when sewing through thicker materials.
You might be able to get away with using the home machine if you used the handwheel to drive the needle rather than relying on the motor, unless you messed up the timing on that one too!
Between the two, the industrials are easier to work on and I find the parts a bit cheaper. I just finished repairing an old Yamata GC8500 that I saved from its previous owner who had somehow managed to snap off every arm on the thread lifter assembly, crack the presser bar, cracked the oil pan (?!), and snapped the needle lifter lever in two. With owner's manual in hand it was cheaper to fix this industrial myself than it was to have my home machine tuned up and certainly cheaper than having to buy a whole new machine.
Best of luck!
