PFG Live Kinetic Precision - Spencer Webb

Lapping From Ra to Rz - I was challenged by @proteummachining to start looking at Rz rather than Ra for surface roughness. Let's see why.

Wireless Devices In The Shop - In which I cross the streams. Inspired by @JohnGrimsmo having issues with his Bluetooth probe, I find it necessary to talk antennas. Again.

The Joy Of Unnecessary Precision - We love to chase it, but at what cost? If you're doing it as a business, know your limits.

3-inch ToolMakers Flat: First Lapping! - After all the preparation, I finally do the first lapping... and it rocks. Process improvements will, of course, ensue.

The Expensive Stuff Is Cheaper... Again. - In which I buy a carbide tool which was cheaper, and end up breaking it. Then buying what I should have bought in the first place.

Buying Stuff To Take Apart And Learn - My son, Jared, asks if we can buy a thing to take apart. Because he wants to design a better one. Correct parental answer?? "OF COURSE!!".

Of Clock Springs And Toolmakers Flats: Turning the 52100 steel produced some pretty evil chips. Some of them broke.

52100 Steel: Planning The Heat Treatment: We are ALMOST running the recipe recommended by the NBS (now NIST) many years ago. Will our minor deviations matter? We'll see.

A Box Of Grinding Gems From Tom: Books and goodies from Tom Lipton. Very neat stuff, and the knowledge was hard-earned by our ancients.
