What Did You Buy Today?

[woodchucker]

I'd hesitate to say "fetish" since I don't worship them, but they are sometimes in the back of a drawer like a good luck charm, only brought out for special occasions.

I often wonder at my interest in acquiring tools that can measure orders of magnitude smaller than my capabilities to achieve this, and certainly my SPI Bore Gauges, which indicate out to 0.00005":

(only spent $175 on them, otherwise something like this would never be in my collection)

All of my setting rings also go out 5 significant figures to the right of the decimal point; somewhat ridiculous when checking an inside micrometer that reads to 0.001".

only $175??? where'd you steal them from? New or used?

Calibrated and never used; @twhite got them as part of a haul last year, didn't need them, I was first to contact him and we agreed on a price. I know, he & I both suck!

My attempt at humor


I didn’t zoom in on the pair so didn’t notice: that makes a nice mixed set!

I saw during my eBay search that they came both ways and not sure which part numbers indicate the difference. My 0 - 1”/25mm is digital metric as is the 2”/50mm - 3”/75mm but I don’t know about the 1”/25mm - 2”/50mm as it’s in an unopened sealed new box (fingers crossed that I don’t need to use eBay’s guarantee).

Ah the nuances of board postings. My understanding, without double-checking the Mitutoyo catalog, is the Mitutoyo #159-101 has the imperial digital read out & metric thimble. The #159-211is the metric digital read out & imperial thimble. There are also 193 models, I haven't looked to see what the differences are.

So only 189 more to go?

I've purchased a Jacobs rubberflex chuck and a set of collets for my old Hendey gearhead lathe. I mounted it and chucked up a .500 guage pin and checked the runout... it was 0.003"...

I dismounted the chuck and inspected the taper inside the back and the taper on the spindle nose (L1 taper)... the chuck looked good, but the spindle had some dings in it. I lightly stoned the spindle taper to remove any high metal, then re-mounted the chuck... that brought the runout down to 0.0009"...





Is 0.0009" typical of these rubberflex chucks? It's probably close enough for what I do...

Tile and sheetrock from the bathroom demo . It did not arrive so it's holding me up .

I thought it looked cute

Actually should work good in my very small wood working area. Have a shelf above the bench I'll replace with one wide enough to hold this. Maybe get a couple more or do something similar with the laser.

I must admit, I have one of these myself, though of a different "brand" (SGS)..

Smaller than expected though I am sure I can find a use for it......... eventually.
