What Did You Buy Today?

That is a good idea, but in doing so, you loose the ability to disassemble. Even thought about putting a bolt in its place but the nut and head would protrude past the flats on the holder. The best my pea brain has been able to think of so far is to upset one side of the pin creating an interference fit, but that would likely result in opening up the hole the pin rides in.
Its a competent little tool, just clunky to set up.

not really, you disassemble the pin by heating it with a torch, and punching it out with a pin punch.
none of them is perm, all break free with heat.

Clamping the workpiece at an angle on the vice

I am wondering if anyone has attempted to make use of this kind of digital angle finder or protractor to quickly set the workpiece at the wanted angle on the vice. I have bought one at a good price ( ~ 8 USD ) and measurement with my DRO-equipped mill indicates that the error is within 0.1...

Just wanted to show the wrench I made for my collet block set. The knurled ring was not sufficient to lock the collet so I fabed up this wrench. Pin is from a turned down set screw. Fits nice in the collet set case. Even the short handle allows for plenty of torque to lock the collet. 20220303_215400.jpg20220303_215253.jpg

Ah, now you're going to need a set of gauge blocks to set up angles with the sine bar! Yes, it's a slippery slope! And guess what, there is no bottom to the slippery slope on this hill!

Good question ! My set came with probably the same sheet lol. No idea what the units are. Millionths of an inch?

Bought another one of these "head lights" today. I've been working on my nova and for the last 40 plus years I've been fighting drop lights trying to get the light to stay where I wanted it so I could see what I was working on. I saw an ad for a light like this and ordered one. Right now I don't even know where my drop light is. I automically just grab my "head light" when I walk into the shop no matter what I'm working on. It's made working on the car much easier now, and on my lathe and mill nicer also. I bought a second one for when the battery goes dead in about 3 hours.

I am doubting that my set has proper deviations. Some of the blocks are negative, and I see them as positive.. so I don't match. On others I am right on, or close. Some show more than they show. Did they really run these, or do they make them up? I have some real Johanson blocks, just a few.. They match my mics, and they match their blocks... So I believe my mics are calibrated. Starrett and Mitutoyo.
They do not have a certification stamp, but they match and then they don't.
