Ken,
Years ago we used to modify them to sew 3/4" of leather & sold alot of them,but from the factory as-is they'll do 1/2",it has a very large bobbin & can take large thread the biggest problem with them is the feet,they are large & will probably have to be narrowed down so you can sew close to things assuming of course you want to sew leather.
We have most parts,needles & thread in stock for it.
Bob
