I have to say, every once in a while I use it, but 99.5% of the time I use the first vise. I just move what I am holding in it, to get a different position. The Proxxon was supposed to be good, it's ok, but as in all the adjustable ones I have tried, it moves around no matter how tight you make it. Tightening on a ball mount is not really holding much.
I use leather on the jaws my vises. It allows me to hold all kinds of delicate parts, as well as gripping all parts without slipping.
These tiny ones make me smile. My dad has 2 vises(?) in his workshop. The lighter one can withstand smashing it with a 10lb hammer until your arm feels numb.
I'm not sure I could easily lift the heavier one by myself. I'll have to snap some pics and post them. :D
Come to think of it, I think he even has an old fashioned anvil somewhere as well.
I got train tracks near if i need to smash pennies. Laughs
What need is small swivel vice like this one that can reach across small circuit boards. Three inches seems plenty big for flashlight work. Metal of course in case i need to heat up a pill or something. Any serious cutting, grinding, hacking you know general "human lathe" stuff, should i attempt, would do on my heavy shop vice. Think ill look see what HarborFreight.com has also.
Wouldn't you be better suing something less thermally conductive? I tend to use an old firebrick from a storage heater. Especially with a butane soldering iron that doesn't care where the heat goes - more comes out of the sides than the tip
If you do a google image search for "peg vise" you can see all the different ways that these little vices can be useful. Also worth nothing, the handle unscrews and you can then clamp the vise into another vise.
