Randy’s Moxon Vise on the Cheap

RandyHawaiiAdded on January 30, 2012

I finished a poor man’s version of a Moxon twin screw vise, and thought others might want to see it/ make one. It measures 28 1/2″ X 5 1/2″ X 1 1/2″ (each face) I used some reclaimed Mahogany, and some scrap black maple too. I have 25″ between the screws, and the max. opening is 3 1/2″. I have two more screws that will allow for a max opening of 15″.

I drilled the washers so I could plug weld the faces, and also tack welded three points on the inside of the washers, The mounting screws are drilled on the flats of the nuts to give me max. room for the 6 X 3/4″ screws. After I chopped out the receiving hole for the hex nut and washer, I used the acme threaded rod to pull everything home.

The face board was drilled 1/8″ above center so the face would not sit below the back jaw. And I used a 3/4″ PVC (200 p.s.i.) pipe, so I could get the angle to the jaw, and as a sleeve to protect the screw from damage. I made the washer from a piece of UHMW (I know it’s very pink).

The bottom line:
12′ Acme rod, 10 nuts, 10 washers, (4) 4″ cast iron hand wheels threaded 3/4″-6 was $236.52 (including UPS to Hawaii $90.00). So I figure my unit cost for one Moxon Vise is about $55.00. I hope you enjoy making your own jig’s, and fixtures too.
