- Jun 3, 2002Phil,I'm still here. I just bought an old 10" shaper at a sale a few weeks ago so I got a little distracted.I also use my boring head on my lathe. A while back I bought a cheap wedge style tool holder and one of the holders it came with had a cheap Jacobs type chuck mounted on a 3/4" shaft which fits in a 3/4" hole in the holder. I happen to have a small boring head mounted on a 3/4" arbor so I just stick it in the tool holder and away I go!Mario----- Original Message -----From: philteagueSent: Monday, June 03, 2002 5:28 PMSubject: [mill_drill] Re: Running out of things to postArt:
I do the same thing with my lathe. However, I needed to bore a hole
that was a little more than 3" deep so that my longest 1/2" carbide
boring bar would not reach quite as far as I needed. I did make it
work, but, it got me figuring on how I could make a boring bar as I
described. I also have used HSS bits in a boring bar as I mentioned.
I thought as long as I had this mill/drill I might as well try and
make something (the boring bar) with it.
I have used my mill/drill to bore holes and I am sure I will continue
to do it in the future, however, I think I actually prefer using the
lathe to bore holes. One thing about using the lathe is that I have a
power feed, something I lack on the Z axis of my mill/drill.
PS It's good to hear that others are still reading this newsgroup.
