I need an end vise, I would like a twin screw. Does anyone think this would work, to mount
two tail vise screws on the same end face, would it work well that way? Maybe buy two
bicycle sprocket gears, have the local machinist bore the centers to fit the shafts outside of
the mounting flanges, and weld them on. Any advise or ideas on this?

I don't see any theoretical reason this wouldn't work. One downside of this
approach is - unless you incorporate some method of disconnecting one sprocket
from the shaft - you have no convenient way to cant the vise jaws.

Another downside might be - and I haven't run any numbers, so I'm not certain
about this - when all is said and done, you may well have as much or more money
(and time) tied up in the home-designed vise as if you had bought one. I'm often
surprised to find out how much it costs me to "improve" on a commercially
available item, not counting the time invested.

What a pain for minimal savings. Just get the Veritas and support a great
US based company, Lee Valley.

I was thinking of their LV tail vise screws because they are 2nd to the the least expensive
I can find on the 'net. Minimal savings? 32.50 x 2 = 65.00, bike gears 12.00 = 77.00,
machinist 20.00 = 97.00, chain 6.00 = 103.00 hardwood handle doweling xx.xx etc etc...
mounting nuts and bolts xx.xx jaw wood 15.00 to 30.00 on and on, you might be right.
But a PAIN? No, the creativity compensates for that.

Now that is too true Tom, good point! Unless I use a chain breaker, that would
be inconvenient.

Another downside might be - and I haven't run any numbers, so I'm not certain
about this - when all is said and done, you may well have as much or more money
(and time) tied up in the home-designed vise as if you had bought one. I'm often

That I answered in reply to Brian's reply. Very true point as well.

It is a great company, but isn't it based in Canada? It isn't part of the US yet...

Hehe, fine. North American based. :-) Still a rarity these days.

I think most companies are N. American based... we just won't pay what
it costs for them to sell American made tools..

I just posted some WIP pics (@ ABPW) of a pipe-clamp based end vise I am
building. Look for:

I know I replied there. Might be a cool idea for me. 'Cause I be a po' boy!
