How rare are the Heavy 12 lathes (technically 12 3/4")? A few years back I had a chance to buy this South Bend Heavy 12 lathe. It was misidentified, showed little use and had a fair price. I believe it was in Scottsdale Arizona and I even drove over and looked at it because they had other tools also. I passed because I had a Heavy 10 and this 12 had an extremely short bed. I even considered swapping the beds but that e would have been extreme for the extra inch of swing. I do think about it whenever I try to clamp an oversize item in mine. I have even owned a SB 13" since then but I always liked the idea of a Heavy 12. I found info in a manual I have but I have never seen another.
