largest 4 jaw chuck that will fit on a heavy 10l

[Ohio Mike]

Generally a 6 inch chuck is consider optimal, the Heavy 10 will swing a tad less than 6 inch over saddle. So for long works its a nonissue.

I recently turned bearing seats in a heavy wall piece of pipe on my heavy 10. Piece was 6 1/4” OD, 3/4” wall thickness and 8” long. I held it on the ID in a 6” four jaw chuck. I couldn’t hold it as well in a 7 1/2” four jaw chuck I have as the jaws were too big to fit completely inside and would not clear the ways on the outside.

Probably the largest piece of stock I would attempt turning unsupported by a center of some sort. I removed the cross slide cover for clearance to cleanup turn the OD. Light cuts and slow rpm.

Hope this helps.

That was probably low back gear speed, plus low on the motor-countershaft belt too!

I bet that had a pucker factor of @ 6-7 .
