QCTP Boring Bar Holders

I’m a firm believer that you can never have too many boring bars. If nothing else, this is an application where rigidity is always a problem as you reach down a hole with that long skinny boring bar. Shorter bars and fatter bars are more rigid, but they don’t work for every case. So you wind up needing a big enough selection so that when you go to find the shortest fattest bar that will work, you’re in luck.

With those random thoughts in mind, I enjoyed seeing this photo over on Chaski of Frank Ford’s set of boring bar holders for the QCTP lathe:

They look like they’ll hold the bars with less chatter than the usual cheezy stick-the-bar in a square slot holders…

And while we’re on the topic of boring, though not of QCTP boring, how about Glenn Wegman’s horizontal boring setup on his lathe from the same Chaski thread:

Notice he built a table to sit on the cross slide to hold the work…

With machinists, where there is a will, there is a way!
