Butt Ugly Mitre Jack
Inspired by looking at Auscabs lovely Blackwood Mitre Jack and Gradine benchcrafted version.Tehe vines reminded me of my limitations of what I could achieve with angled dense timbers on shooting boards _and the pain it can be working precisely on the sides on angled parts- aka angled tenon
So I put this thing on top of my bench vise.

Thea vertical member below the vices to ensure parts are installed 90° and the funny stepped part of clamped to the vertical for angled parts- I can knock up other angles as per need.
The thing is satisfyingly accurate - it would close 4 mitres of 100mm thick members with no gap, based on the measurements I took and I could likely active better.
And this is with nice crisp shot edge.
It's held on with the 3 bolts and one pin, removal sis expected be easy and the timber itself is sacrificial.
Have some thoughts of rebuilding these end of the bench to incorporate the sacrifical timber at bench top level, and perhaps improve raking control, but this can wait

Good problem-solving there, Martin...
While it would be a fun project to make a 'real' mitre jack, it's probably something only pros or very busy amateurs doing a lot of work that needs accurate trimming who would really benefit from having one. Your solution is probably as good as the more elaborate vise for those of us only needing to trim an occasional mitre. I've often thought about making one (using a wooden screw), but I'd probably use it once every two years, and I already have too many bits & bobs sitting on shelves gathering thick layers of dust...
Cheers,IW

Common problem that one- I have a list of gear for "enhancing precision" - way to long and unlikely. This does the job along with the disston 77 style saw and its cleaner cuts -( reduced chip out).
Next problem is building it in and replacing the vise with front screw vise with minimal racking- maybe replace with a twin screw vice and put an extension/ corner one end. the extension could act a tail vise. - no hurry this,good for now, feels better.

One more thing- intend to insert angled jaws to the vise as well- long edges can then be shot or crazy parts the sweep on two angles. Will make the jaws as need then dispose of cause they would gather dust.

I felt the same way. At the time, about to make one and found one nearly unused from England for $125 shipped.
And at that, i can't even justify wasting the 16/4 beech in a bigger billet.
i've used it about four times, so buying was a good idea. I remember thinking how much more work I'd need to do on a complex moulding that I used it for if I didn't have it - and was glad I did. but the work would've still been less than making one, even to trim and fit freehand by hollowing the center of the miter and adjusting the outer edges. Which I still had to do, but a lot less.

Fitting something to the vice is a good idea.
A more complex step would be this. For tenon cutting, its slightly easier to make than a mitre jack. If you have the screw cutting gear. Or use steel square or acme thread clamp parts that can be bought. It clamps to the rail and the rail sticking out underneath is clamped in the bench vice.

This is an interesting set up I saved pictures of. It looks like tenon cutting device built into the bench end.

If only that bench could talk, Rob! Looks like it's had a very long & busy life....
