It's Alive - It's A Live Tailstock Center with a Tach attack omiter
Well, not truely alive by purist terms, but live is commonly used to
describe a ball bearing center. This center appears to have a built-in tach. Are there other centers with built-in tachometers?

Ahh crap, I think it's actually a pressure indicator. Looking more closely
at the picture, I think the gauge face reads "lbs x 10". This is one that reads pressure, although the dial isn't visible ROHM LIVE CENTER W/PRESSURE INDICATOR 5 #5MT eBay Item 33009763354 http://cgi.ebay.com/ROHM-LIVE-CENTER... 286.m20.l1116 WB ..................

No problem, just mount a Tachulator pickup on your live center.

Thanks for describing the purpose, Fred, since I didn't have a clue.
My guess was that the pressure reading might've been useful in precision grinding. WB .......... metalworking projects www.kwagmire.com/metal_proj.html "ff" wrote in message ...

Because the forces in precision grinding are low, and the operation is almost always carried out with coolant, spring loaded tailstocks generally use dead centers, carbide preferred. They don't introduce error, unlike a live center. Harold |

Great to see you comment on grinding again, Harold. It makes sense that
temperatures are negligible in high precision grinding, and that dead centers would be a logical choice.
