Re: Does anyone else get this message

BDD: Thanks for the IT advice. I do nearly all that you suggest, but back up only once a month or so, because I don't work from home or do anything that I need that isn't already backed up. The worst thing that happened was my personal user file was corrupted by a MS upgrade, and it took a few MS ph...

dorin: Thanks for the revised URL

BDD: "....but I'm completely baffled why anyone uses that junk."

What do you recommend instead of McAfee? I have used it for years with no problems, but am not stuck on it.

Re: Does Dykem go bad?

Me too, No amount of shaking restored it to its former glory. Bought a new can from McM-C. I use markers for small coverage but the Dykem for serious mistakes... I mean use.

Re: 4-way toolpost build

Steve, I forgot to mention the obvious. Make the slot in the tool holder low enough so that the largest bit to be used does not have to be ground down on the top to reach the center height. Not a problem with 1/4 " or 5/16" bits, but easy to do with 3/8" bits.
Just a heads up.

Re: 4-way toolpost build

Steve: This is the tool block that I use on the Atlas 12" and it uses 1/4-20unc set screws for clamping. I made the slots 3/8 deep by 1/2" wide so there could be a clamping shim on top of the tool bit so the bit doesn't move when the screws are tightened. No problems have been found in the 10 or so ...

Re: Undercuts and stress risers

I looked in the textbook "Formulas for Stress and Strain" 5th ed, by Raymond Roark and there is a 3 page section explaining what stress concentration is along with formulae. There are also 20 pages of Stress Concentration factors in the table XVII. It is interesting to note that all the stress loadi...

Re: Determining an angle of a blind pocket ?

Woods Metal which melts at 165°F is often used for this purpose. I have used it for many things including rifle chamber casts.

Re: Mill tooling

Lots of posters will not agree, but with this setup of a #40V flange EM holder that is keyed to the spindle and holding the EM with a set screw on a flat, I have never had an EM move or slip. Break, yes. no slip tool holder.jpg I have a friend who used to work for SGS Tool, testing cutting tools. Hi...

Re: Another dumb question...

John: The overarm support on my Horizontal has a brass bushing adjustable for diameter like a collet. It runs on a polished stud that is smaller than the thread minor diameter that clamps the bushings and cutters tightly.
