Metric slip gauges, I nearly ruined them ( making my own )

[@eddiewoolfie3891]

Well done, Darren, jings you have some amount of patience. The slips look spot on. Great job 👏 👌

[@bryansbasement5331]

Great job buddy, hard work and patience payed off, shame about the microphone but you rescued the video, time spent in the workshop is always therapeutic even if it’s a long tedious 👍🏼👍🏼👍🏼

[@helenmcgarry42]

You have made them better than they were when you got them. I call that a good job and as long as you are happy with them seen as how you are the one using them then thats all that matters. Proud of you no matter what

[@WobblycogsUk]

Good job, I'm sure you'll get stick for them not being factory accurate any more but as long as they are accurate enough for what you want to do with them they are fine. I would be tempted to try and get a more accurate micrometer and a known good standard, measure them all and make up a chart with the sizes.

[@Darren_Barclay]

@@WobblycogsUk yeah I had thought about that, but I was happy that they are good enough. Its definitely a smart idea to know exactly what they measure and how much they are off.

[@barrymcdonald7521]

I think a lot of people are gonna be triggered by this video so be prepared for that. The blocks were unusable from the start though because of rusting so no harm done and you have a set that you like and enjoy so good for you.
I would however not use these as gauges. The accuracy you should trust these to will be the same as the accuracy you can read on a set of calipers, anything that needs higher accuracy should be measured using gauge blocks within much tighter tolerances of what yours are in now. These I would just put on a shelf as a nice piece of workshop furniture. I would also suggest you use the ratchet on your micrometer to get a more precise reading, otherwise you risk over tightening. Thanks for making content for us to watch.

VPI paper is not the same as greaseproof paper

[@Darren_Barclay]

@@johncuthbert1888 basically the same. Well it never done its job really, since it was the moisture that built up on that paper, I debated whether to even put it in, it’s a fine replacement.

[@Darren_Barclay]

The only difference between them is one has wax and the other silicone.

[@johncuthbert1888]

@@Darren_Barclay The difference is that one has something, typically a volatile salt of a high molecular weight amine which acts as a corrosion inhibitor. It doesn't last forever; that goes with the territory of being volatile.

[@Darren_Barclay]

@@johncuthbert1888 yeah I get it, but the silicone grease paper is a suitable substitute, especially the price. That was the point in doing them, I wanted to do them without spending a lot of money, I could have just bought new ones.

[@robertfontaine3650]

While you may be able to clean them up you can never make them true.

[@Darren_Barclay]

@@robertfontaine3650 true to what scale but, am not making parts that have to be true down to the microns, they are good enough for me, the measurements don’t lie.

[@spuhr_ex_gunsmith7375]

I don't like this at all., I do understand the acid and polishing part but the idea of measuring with a caliper and milling them is just no good.

[@Darren_Barclay]

@@spuhr_ex_gunsmith7375 I hear you, I spent days thinking about it, then I just went, might as well try I knew I wasn’t gonna use the imperial set. Rest assured I’ve got myself another incomplete set with the ones missing so think I’ll just swap them, but as said in the video, they measure pretty good, they will be off a few hundred microns but good enough for me. But remember they were a rusted mess, surely ive made them better no.
