Little Things Make Me Crazy

knobs and wedges 005

 

I’m slightly anal about some things, while other things don’t bother me at all. I have been masquerading as normal for a long time, but sometimes the little things just get the better of me. A while back I bought a quick change quill lever for my Bridgeport mill that was obviously an offshore piece (by the price), but good enough quality for me to ignore that it was Chinee. One of the most obvious tip-offs is that it came equipt with a LOVELY  red knob. This has been making me crazy for six months or better.

Can You Identify This Tapping Head?

I could use a little help, I bought this tapping head at last years CAMS Yard Sale, and have been unable to find any info on the manufacturer. I was able to get a J440 collet last week from Ebay seller C178, and a R8 adapter from JTS Machine, so I’m about ready to start tapping. I really needed to get a larger tap collet than the one I got with the head, because most of the tapping I do is 5/16 or larger. the J441 collet is for a much smaller tap. I was able to (finally) find a collet that went to 5/8 (tap capacity).

What I would like to find out is: What is the maker of this tapping head (there are no markings), and what are the service requirements? I don’t know if the head needs oil, or is it run dry? There appears to be a drain plug in the bottom, which I don’t want to remove unless I have some info first. Heres a couple of shots and the specs off the chuck.
