Large Diameter Clam Shell Knurler

[Shelly142]

Paul,

Thanks for the positive comments. The tool presented here will only accommodate about a 3” dia. max.

Honestly, I didn’t really give much thought to the possibility of a wrench coming in contact with a 3 or 4 jawed chuck. At this time when I have had occasion to use this tool it has been in conjunction with a 5C collet chuck. But that is something to consider for obvious safety reasons. Thanks for highlighting the possible safety issue.
