This jig weighs 26lbs and is a handful. If you have a bigger one, I'd like to see it. Not joking.
I use a 14 inch, long angled lath bastard, file to cut shoulders. When I built this; I wanted a jig that would give, opportunity, to use the whole length of the file and keep it straight as I filed.
You can adjust the rails, that carry the file, so they set 90 Degrees to the tang, giving you shoulders that are square off the face of the ricasso. The adjustment, is accomplished, by turning the threaded bolts, on the back, in or out. {the small ratchet is on one of them }
The jig is spring loaded. When you set it in the vise the pressure of the springs, holds the jaws apart allowing you to insert the blade. This also keeps the jig from falling out of the vise. That would not be good.
The rails are made from S7 steel. They can be removed and surfaced which I do every couple of years.
It is a bit cumbersome to move about, but it produces perfect shoulders.
Happy to answer questions, Fred
If you go to build this, make sure to machine for the adjustment bolts. Adjusting the plane of both sides aligns the rails where the safe edges, of the lath bastard file, rides.
Once I have the blade in the jig, I screw the bolts, in or out, depending on which way the rails need to move. Align the top of the rails, with a straight edge, tap into alignment, tighten the c clamps. File away!
There are machined pockets that carry the springs. When you loosen the wing nut, shown in photo, the springs push and hold the jaws open.
