Just want to bounce some ideas off of you guys. I'm planning to build a ratcheting board jack that can be clamped into my tail vise. Thinking about cutting a groove into the linear part and using dowels to function as the catches. I plan to make a pawl out of ironwood and apply light tension with a coil spring.
Have any of you guys built this or something similar?

Hi Brian
I have a sliding deadman, but out of interest I Googled and came up with this ..

There must be many ways to do this. All should work.

More like this:

But where the jack actually ratchets for a quick height adjustment.

how much quicker than setting a peg do you need? seems that those holes could come in handy too for other things that might fit in the dog holes anyway....

More often than not I use my bench slave/sliding dead man to support boards much shorter then the length between my front vise and tail vise. Don't know what your distance is or if that would present a difficulty for you but something to think about.

I'm not as creative when it comes to a board jack - although I need one often. This solution was cheap, but it's worked pretty well since 08.

I always wondered about this board jack in the tailvise. What do you do when the board to be clamped is just a little too short to reach it?

Going back to the drawing board on this.
