Jet Mortiser with a XY Vise Mod!

I made this modification to my Mortiser some time ago and it really has made the procedure far more repeatable, easier, faster, and safer.

I was tired of the really bad fence and stop that came with the Jet so I started doing some homework (back in the days before the internet and you had to go dig up that old copy of Woodworking Magazine) and found an article that showed you how to reverse the top of this vise to get it to work on the custom base I made.

Not a rocket science project but I hope it helps someone who suffers through the same issues I once fought when mortising.

Nice. “There is nothing like a mechanical advantage.”

What’s the base made from?

I just laminated a bunch of scrap 3/4” MDF together, making sure everything was as plumb and square as I could make it. I left an edge on both sides so it can be clamped to the bench.

Very nice improvement Brad. I have a horizontal mortiser on my combo machine, but I often wished I had a vertical one like yours that can cut squared holes.

I set up my mortise in similar fashion…. and would note that you can smooth out the ways on these China vises with either a stone or emory paper on a plate. This will enable you to keep the force required to index the vise low when you tighten up the gibs to get the wiggle out of them.

You are absolutely right. The vise is what it is. But, I had my machinist friend take it apart and put it back together and he took all the play out of it and made everything operate far more smoothly.

Tuning tools has become so second nature over the years that I forget sometimes that it is not in everyone’s bag of tricks.

Thanks for bringing it to everyone’s attention.

Good job on the mod, also if you ferret around you will find a chuck extender,

If you cut the shaft down you an fit a chuck to the morticer and use it as a drill press, fixed speed though!!
