Soft metal lead has a very high co-efficient of friction. But does lead grip well in a vise? Sadly, not according to my test. Thanks for your help making these VJOs! I made some funny safety stickers here:

If it didn't make me dumb I'd be smart enough to use it.
You could electroplate the jaws. Its an easy process and a machined surface finish will create an electro layer of uniform thickness.
Well if the lead is gonna go around the object shouldnt you test it with a object with something for the lead to catch on??? If its smooth youre just gonna displace it and then it will slide right off.

Very impressive HAHA
Wipe the hot solder with a piece of VERY CLEAN cotton cloth. The solder will spread, like a coat of paint.
id love to hear from u bestfixit@gmale dot snot
I watched your other Vjo on comparing the other vise jaws and I think I know why the softer stuff doesn’t clamp as well.
You’re clamping at the tip top of the jaws where there’s no steel backing it and so the jaws are flexing back ever so slightly. Try backing the soft jaws with some steel up to the full height of the jaws (parallels work in a pinch, or better yet the steel jaws themselves). I’ve always used a soft shim on the moving jaw side backed by steel and have had tons of clamping pressure though I’ve never tried pushing it out with a jack before.
speaking of holding power, would love to see a comparison between R8 collets vs ER32 collets. Most home shop folks have mills that use R8 collets, but I have noticed occasional bit slippage with them. Have gone to ER32 sollets and have not seen any slippage with the ER32 collets. Would love to see some quantitative testing

"Penishield" that's a weird name for a tool thing
I'm crossing my fingers for stickers more the size for hard hat'n
"Once it is set up though, man she runs like a-… An alarmed hominid." Nobody here is for the tools. We're all here for you. Dammit man, never change.
Wouldn't copper be a bad choice because it would work harden?
Cut a 2,5mm dovetail in the soft jaw and a 2mm in the part. Nothing will rip it out and you can fly cut it out in the last op.
I remember the old days as a 6 year old, smelting kilos of lead on my grandma's kitchen……
Aluminum and copper have even stronger galvanic interaction.
