The Home Machinist!

It's pretty "industrial" but you may pick up some usable info.

You're welcome you Lucky Dog!!

I wish I was located that close to Tahoe

ASTM A529 Steel Categories: Metal; Ferrous Metal; ASTM Steel; Carbon Steel; Low Carbon Steel Material Notes: Copper content of 0.20% is a minimum when copper steel is specified. For plates wider than 610 mm, the tests were taken in the transverse direction and the elongation requirement is reduced b...

Usually I see machinability qualities listed, but in this instance, only cutting and welding. I would suspect for that reason it is a structural steel, but I am not...

Some decent info on coolants and filtration here.

As I mentioned toward the beginning of this thread, using the 3:00, 6:00, and 9:00 method works well for round holes. Another simple solution in many cases is to simply hold the DTI by tho top dovetail ss the dial remains flat ehile rotating. http://img.photobucket.com/albums/v647/Fighter1/P1030909....

Ahhh, this is unfair!!

Attempting to shame me into yet another research/development project eh?

I already purchased everything I needed to do it about 7 years ago. Couldn't purchase the time though!

Hmmmmm

Actually, Music Wire is very common for commercially wound springs, if not the most common generic spring material for smaller size springs. A few other varieties from the Catalog are.

Ever seen one of the old Hardinge "Super Slant" lathes?

Slant beds are now fairly common on CNC turning centers.

Not really what Tim is asking about, but since Jose brought up enclosures:

I use Zero/Haliburton

They got 'em all, and boy are they nice!

Lots of great info here!

Thanks!!!

Sort of relavent.

A suggestion is to possibly keep some Stressproof or 1144 on hand for shafts if warpage during machining is a concern. A little harder than 1018 etc. and machines nicely too!
