Moxon Twin Screw Vise - Budget Version

I finally broke down and decided to buy a real vise. Then, I remembered the Benchcrafted Moxon Vise.

The store had one, but I didn’t have $300 for something that excels at squeezing real tight. $83 and a new friend at Woodcraft later, I had a tap/thread kit, some 8/4 popular and a hardwood dowel.

I spent the better part of an hour planing down the cupped poplar (agonizing video here), followed by some vigorous headscratching with the tap and thread. I don’t have a lathe, so I just bought a 1.25” diameter maple dowel which is the diameter of the threader. You drill a 1.25” dole in the face piece even with a 1.125” hole in the back piece that is to be threaded. Use oil or paste wax to lubricate as you cut the threads.

The handles aren’t very romantic, but now I have more vise than I’ll ever need.

Dims: About 32” long, 24.5” of clamp width and 8” of extension. I added a cleat and use holdfasts to hold ‘er down. There are various ways to do this. I found using clamps on the back jaw wasn’t stable enough alone.

You don’t really HAVE to have a non-slip surface in the jaws, but it might help. A harder wood would prevent the slight bowing of the jaws when clamping narrower material. If I really go at it with the saw, it shakes lightly. Frankly, I use it as a reminder to let the saw do the work or sharpen for Pete’s sake.

I don’t necessarily think this is any better than a $250 twin screw vise (it doesn’t have a dog hole or anything), but I’d bet that I’ll revise statement after I have had to dovetail a 24” panel in wood I could afford with the money I saved.

This was a great project to practice:

- Drilling straight
- Chamfering
- Using paste wax (for the threads)
- rasping/filing down tight spaces and circular objects

Of course, I can say I made my vise. No one will ask if it was pretty or not.

Dallas I think it looks really good, and a perfect match for your bench.
I have bought one of those taper sets, made the dowels and… This was a month ago… Now I need to kick my … soon and get to make it after seeing yours.

If you think its too it shaky I would suggest sawing of a inch or two of the top, then you will get the screws closer to the tension point I think that would make a difference, but ofcourse it will be a little lower.

Best thoughts,

Hey Mads,

Great thought about shortening it. That would help the shaking.

I can see that now.

Nice set up and craftsmanship. Have drooled over all the various high-end vises in the catalogues, but sadly can’t afford them. I think this is a bit more my speed and price range, will definitely have to try it. Thanks for sharing!

What about drilling two holes in the back jaw, one each for the hold downs? That might transfer pressure directly to the back jaw instead of a kind of pivot point with the stabilizer that is currently being clamped.

I been wanting to build one of these for a while now. Very cool to see your handy work this morning to rekindle my urge to build it. I too considered getting a tap and die set but struggled even with the cost of that (I cant see me using it that much). I been considering making one out of large diameter All-Thread, but just cant seem to make up my mind.

Thank you very much for sharing this with us… Im going to definitely favorite this one so I can come back for notes… I like what you did…

P.S. Love the Bad Axe! Just recieved one as a gift from a very good friend. Got to be the coolest saw I have ever held in my hand… Two thumbs up IMO….

I love the look of this vise, I can see mounting at the end of a bench. Thanks for sharing.

What he said. I like it, thanks for showing the idea. I can afford this vice and still afford the project material to use it on, LOL.

I’ve built these vises using maple for the jaws and they still flex under pressure. It just proves the point that you really don’t need to reef on those screws to hold a board in place.

I bet the Moxon vice will also bow the jaws under pressure. The way to improve that. would be to move the two screws closer together. Less than 1/3 the length of the jaws from the end, but probably more than 1/4. What you’re going for is roughly equal pressure over the full length. Too far apart and the center doesn’t get enough. Too close together and the center gets too much pressure and the ends don’t get enough. I’m sure there’s a formula for that but it’s been a long time since I went to school :)
