Lantern pin vise

[mklotz]

It's impossible to securely grip a bolt, or anything shaped like a bolt, securely in a conventional lathe chuck with the head end of the bolt in the chuck jaws. This difficulty led to the creation of something called a lantern chuck which provides a recess to accommodate the larger diameter portion.

I've often thought that it would be handy to have a hand vise that had the same feature for holding bolt-shaped objects. I made a trial version from aluminum...

because, at the time, I didn't have any suitable steel. This isn't something one uses very often so the softer metal hasn't been a problem; besides, it prevents marring the workpiece.

Interesting idea. Did you cut a longitudinal v in the jaws?

I'm often having to shorten bolts and screws and this looks like a good basis for what I need. I also think I'd do away with the thumb wheel and either use an Allen head or a screw the other one on your vise so it could lay flat on the bandsaw table I usually end up using.

Thanks for sharing.

No, I didn't but only because I never got a round toit. It's a simple job and I'll do it the next time I have the mill set up to cut V-grooves. So far I've only used it on small non-cylindrical parts.

Marv,

I am always impressed by your ingenuity. Thank for sharing this handy tool and also thanks to C-Bag for the suggestion for laying the vice flat. I will be making one these in a similar style to your vise and in aluminum.

Yes, a deep bow to your vast knowledge and expertise Marv. I have learned so much from your posts. Especially nomenclature.

I'd never heard of the term pin vise before one of your past posts, now a lantern pin vise. Is that because of the hole for head of the bolt? I'd always seen lantern style referred to on some lathe tool posts and never thought about it thinking is was just an obscure reference. But I guess if it didn't have the tool holder in it, it would resemble an old lantern. But I almost never saw them without a tool holder in them.

Lantern in this usage refers to anything that sort of looks like a lantern. A "lantern" tool post has a sort of cartouche-shaped opening into which one inserts the lathe tool. Viewed conceptually, it looks a bit like an antique lantern, the hole representing the "window" through which the candle flame was seen.

Jump forward to modern times (well the early 20th century) and a lathe chuck with a window to accept mushroom-headed parts comes to be called a "lantern" chuck. See this post...

for my version of same for machining the ends of screws.

As you surmised, I carried the nomenclature over to this pin vise because it accommodates the handling of mushroom parts.

Nothing sacred about the name; if it looked as if it had grown underground, I would have called it the truffle pin vise. :-)

Thanks Marv, yet another thing in the to do list !

I'll never get caught up. I like it enough to go and build one.
