How the heck is all that used?

Cool. Not something you see very often 2nd hand. There have been a couple times over the years where I'd wished I'd had one, but would never use it enough to justify the cost. Something I keep looking for at industrial auctions hoping to pick up for pennies though.

There are various points and ends, but the gist of it is, you can clamp together a stack of blocks with say "points" or "pins" and have a very accurate spacing between them. Used to calibrate gauges or machines, for layout, or for hard gauging parts like a go/nogo situation. That set also includes a base, so you can stand it up like a height gauge.

That's a hot deal. They sit under the bench undisturbed for decades, but still, as a shelf-holder-downer its a heck of a deal .

Got me. It had the requisite words (Mitutoyo, gage block) so I linked it. Was hoping for an explanation. Thx, @Dan Dubeau.

I'm getting there but still foggy.

I'm leery of anything that interferes with my gauge block measurements.

Can you expand on that Dan?

I think its a super precsion height gauge, without spending thousands of $. You stack up the blocks to the height you require and attach the stack to the base (bottom left in that photo).

See the half round pins, of various types? They are a set/known diameter, and you compensate for that # when making your stack of gauge blocks if you need inside/outside compensation. You then take a suitable sized clamp and clamp those on the ends of the stack, and you now have a very accurate set of points/pins at a very accurate known distance apart.

We had to do various labs in college using them to measure and set various things. One of the places I worked had some too, and we'd would use them to set various fixture components into alignment when other means were not viable. Very handy things when you need them, but not an everyday use item for most. You can use them in a variety of ways limited only by your imagination. Just another way to make a gauge block set more versatile.

Every few months we run into a situation at work where they'd be very handy, but I typically find another way to figure it out. Usually taking a scrap of material and putting a couple reamed holes in at a specific distance to aid in setting a fixture component in relation to another one. Not as accurate as gauge blocks, but pretty close, and close enough for our purposes. We can tap stuff around on the CMM to get it closer.

Tres kewl. @Susquatch, you need this. No, really...

 

[Susquatch]

Watched the whole video.

The video is fine and very informative, but.....

all that to scribe a line......!!!!

I think it's best if I just keep all of my negative comments to myself.

Thanks Stel. I get the idea. But his example totally sucks. Can you read/use a scribed line to a tenth, to a thou, or even several thou? I'm in the latter camp and I wanna meet the guy who can do better.

Stack precision blocks to scribe a line ......... Not me.

Yes, but that was used before the era of digital high precision metrology equipment.

I get that. But I bet it wasn't often used to scribe lines......

The set I have is not a height gauge, but has various pieces you'd put at the end of the stack of blocks. That makes the tool somewhat useful, to be able to hold the stack firmly together so you can manipulate it and take precise readings. Last time I remember using it was to space tool makers buttons, had a piece with pressed in dowel pins and want to make precisely located holes in a mate.... short of a swiss jig borer not many to get things that accurate, but also only happens .5 times a decade (at least in my shop)
