I made my vise too, I undersized my first screws ~1.45", while they worked there was too much slop in the front jaw. So I remade them and got them about .010 under the 1.5" That was much better. Some squeaking with them that some wax took care of. I had some 8/4 poplar in the rack that was only 4.5" wide so I used that. Here is a shot

I like the octagon handles…

I built the twin screw vise.
I used a Woodcraft Screw box and the metal tap that goes with the box.
Problems I had were as follows:
I turned the screw blanks a bit oversize and the diameter was not even along the lenght of the screw (lack of good turning skills). I had to adjust the diameter after I cut the threads, a bit tricky so you don’t destroy the threads.
I had to adjust the cutter in the screw box to cut a lot deeper than the factory setting.
I added a garter, and it works well.
Inserting the screws into the vise they seem to be very loose and sloppy, but when I tighten down on a piece of wood, the loosness seems to disappear and the vise holds the workpiece very well.
Cutting the threads with the metal tap worked well when a lot of lubricant is used (Linseed oil and/or wax).
The tap is very hard to turn and should be done very slowly.
Roy Underhill describes screw cutting and nut making without the benefit of a metal tap in one of his books.
He also descrines how to forge your own metal tap.
I can get the title of the book if anyone is interested.
He also did one of his "Wood Wright Shop" video series on Public TV.
There is a website that has all the programs in the series can be viewed.

This was a good project, I love my vise!

Garrett Wade sells the thread box tap & die, sizes 1/2" – 3/4" -1" – 1-1/4" – 1-1/2". I’ve found the cutters normally need sharpening between uses.

You might consider running your tap through your die to make sure they have matching pitches. Any SLIGHT irregularities can be smoothed out this way. Remove the cutting blade from the die first.

Checked out the Charles Neil video. It doesn’t really address the problems I’ve been having which are 1. tear out tangential to the grain, and 2. mismatch between the tapped hole and threaded rod. I only get 3/4 of the way into a 2" hole before the thread binds. I cut a reasonable depth of thread, so it isn’t binding from interference, which really only leaves a small inconsistency between the thread pitches.

I’m not sure who posted the previous comment “After several days of struggling with the thread box,…”, however, before you give up, please look at the following Charles Neil video on using the thread box. FYI.

After several days of struggling with the thread box, I’ve given up on it. Maybe I’m not persistent enough, but time is a rarer commodity than money. I’ve put an order in for a Beall Threading Kit. Given that it’s only double the price, I think I should have sprung for it originally.

The need for this project would be moot if you had simply built your bench at the proper height in the first place
