Re: CBN cemented/insert tooling

I was told the same and picked up a few boxes of inserts that came up cheap on eBay and which fit some holders I use.
I haven't had a use for them so far ;-)

Anybody with LED lighting notice the wagon wheel effect on rotating machinery?

Re: LED Shop Lighting

I would love to get in a time machine and go back to McDonald's, back to the days when they dumped 50-pound blocks of beef tallow into their frying machines. Mmmmmmmm There are still a few Fish & Chip shops in Yorkshire frying the fish and chips (fries to you guys but there's nothing French about Y...

There is one academic study out there that purports to show eye damage from LEDs. It studied mice kept surrounded by intensely glowing LED display screens.
Display screens with a refresh frequency?

This is about the amount of time I use a micrometer or vernier caliper. I worked for several years in a tube man...

Re: Books on machining

If you get THOSE at a pawn shop, how would you know that they are accurate? If you visually inspect the surfaces and they are near mirror finish and they wring easily then you know they aren't worn and haven't been "fettled" by an amateur, if you polish a gauge block face at home it can look right ...
