The '42 South Bend Heavy 10 toolroom lathe I just purchased came with a much abused and badly worn 5" 3-jaw chuck. There are a couple of almost invisible hairline cracks in the body and it looks as though the chuck was threaded on to a big piece of pipe and used as a hammer. I haven't checked the jaws but wouldn't be surprised if they were badly tapered. The chuck functions... but barely.
Four Questions:
EDIT: Side question... the machined piece that mounts the chuck to the lathe, I've seen the called mounting plates, backing plates, and adapter plates. Is one preferred? Are they actually referring to the same thing?
Four Questions:
- As a newbie, what do I look for in a replacement? I have seen them go from $100 to $650. Given my status as a total noob, I don't think I'll get $650 of precision out of a $650 chuck, but is $100 too cheap? Would a $650 chuck really be more than 5X the precision/quality than a $100 chuck?
- Are the backing plate bolt hole patterns standard or should I plan on machining a backing plate (which right now is a little above my pay grade). I would really like to avail myself of a "plug and play" option.
- Can I reuse the current backing plate or just get a new one with the chuck?
- 5" or 6" - The 3-jaw is 5", but my 4-jaw is 6"
