     I need a 3D drawing.

All looks like I can finally do something for the group. I have a

lathe,

TIG, and unemployment. I would be willing to do a bit

of machining to make a few of the notcher's. Perhaps we can make a

few

loaners that we ship around within the group. Lets get a

design together that makes sense.

Perhaps later we can also do something about a nice tubing notcher

for

engine mounts and etc.

Karl

Karl and Paul, and others,
I made a copy of the plans for the tube beader that was in contact mag a
few years ago intending to make one myself, but never did. A Fedex
machinist who was in my a/p class in Memphis opined that it wasn't the
best he had seen, but might work for awhile, he wanted to beef it up,
but we never got around to it. I found the drawing, and if you like will
send it to you, (wish I could scan if, I could fax it), so send me
whatever works best to get it to you and I will send it to you. Email me
at cardmarc@charter.net to let me know
