I've gone indicator crazy lately. 
Couple of weeks ago I bought a couple of Mitutoyo DTI's on a one-day 30% off sale. (Standard and long stylus's.)
Yesterday I got these as well. The two Teclock's are for a "spindle square" that I am going to make - "just because". Reviews of the import jobs (SPI, Edge Technology) are pretty poor due to the quality of the gauges (Chinese I assume) and the Starrett version doesn't seem to fair much better. My late FIL gave me a couple of older Teclocks when he retired and I've found them to be really nice, smooth gauges. Made in Japan.
The Mitutoyo gauge will be a replacement for my Central Tools bore gauge which has been a PITA since the day I bought it off of the Snap-On truck decades ago. The morons that designed it didn't think it through as they used a "normal" dial gauge on it and it reads backwards. Small bores display a larger diameter, and larger bores display a smaller diameter.
I didn't notice it until the first time I used it about a month later , and the **** on the Snap-On truck wouldn't take it back. It works fine for checking tapers but it's useless for direct measurements unless you transfer the reading to a micrometer. The reverse reading Mitutoyo gauge will correct that.
I even contacted Central Tools trying to obtain a new dial face for the gauge and this is the B.S. excuse they gave me.
Yeah, right - somebody specifically ASKED for a bore gauge that works bass-ackwards!

Quote:I am told by our engineer that the reverse reading was requested by the automotive industry many years ago. The 6467 was purposely designed to have the reverse reading. Unfortunately, there is no way to change it.
