Re: Rant about Home Depot

My son in law supplemented his oil furnace with a pellet fed stove in the living room. It works better for not so cold days. He lives in N.J. but that is another story.
Somewhere I lost the transition from HD to heating. Did I fall asleep? :)

Re: Tesla cars

The next time you go near a hospital, I'd bet that you'd see at least one in the staff parking lot. Probably black or dark blue in color.

Re: Dreaming of Rachmaninov on a Train

Thanks, I forwarded this on to my musically inclined grownup kids, one of whom is a music teacher.
Nice video.

Re: Morse taper end mills

The end mill holder that came with the 1958 ATLAS 12" Lathe milling attachment is a #3MT to fit the headstock, but it has a drawbar to make sure it stays in place. Just another vote for the drawbar.

Re: metric drill set explained?

And then there are us poor US educated MEs that learned stress analysis in 'conventional' units and then got hired by a company that only used metric units. It was a struggle trying to deal with MPa or GPa instead of #/in^2 or N-m instead of Ft-# or °C instead of °F or kN instead of #, or rememberin...

Re: Anyone need a chuck?

Check the small tools guys in the link above. As mentioned their 3 jaw 5" chucks had removable top jaws. You'd need a threaded back plate. A note to be cautious about though. The 5" Atlas 3 jaw chuck weighs about 5.5# and the 6" SHAR 3 jaw with replaceable top jaws and back plate weighs 27#. BIG dif...

Re: Spindle collet grub screw

A friend of mine has an older Rockwell VMill and the collet orienting pin is so worn that one has to feel it with a finger and then carefully insert the collet. Some of his collets have buggered slots where he or someone was not careful to get it right. He'd take the pin out but it is practically im...

Re: Twist drill prices

Got to add an example from the Midwest. Ace hardware 1 each 11/32 cobalt twist drill = $11.15 + 6.75% tax = $11.90 I'd say Liveaboard got the better deal, AND his were German made, not Irwin (Chinese). If I had gone to McMaster-Carr it would have been $10.36 + 7.25% tax and not marked as to country ...

Re: lapping internal taper?

If yours is not a production shop, you could get away with making your collet holder from 4x40PHT material and not grind, but polish the finish. A standard brake cylinder hone will do for the cylindrical section. At least it did for a 5C. It may not collapse small enough for an R8 and definitely not...

Tap guides

After all these years I have finally figured out how to get around the fact that the tap guide always has the wrong end out. :idea: I bought a second one. Now I can choose the one with the proper end showing. No more hunting for the screw or spring under the bench or in the chip tray. HAH! --earlgo

Re: Craftsman Micrometers

Thanks to Mr. Marks, it looks like my 'old' Craftsman 2-3 x .001 and my 'new' Craftsman 0-1 x .0001 mics are both made by Sherr-Tumico. Wonder what the initials 'D.J.' mean that are etched in the barrel between the 'Craftsman' and the 'Made in U.S.A.' indicate. It is on both micrometers. I also wond...

Re: Why 27 TPI?

Recall that 1/8 NPT is 27tpi and perhaps the early microphones were mounted on a pedestal that required the wire to pass thru the stand. Maybe this is where the 27tpi is held over from.
Just a theory.
