5cm milling vise

The vise is based on a popular style of vise manufactured by Kurt, but

scaled smaller and around a few handy pieces of scrap and an odd tap.

The body is a strut cut out of the iron frame from a junk George Bent

"Crown" upright piano, but the jaws and nut are some steel cutoffs. The

3/8"-20 lh screw is a nice fit between the 16mm shoulder and 1/4" hex

drive, and it is supported between two thrust bearings.

The fixed jaw is held in place with a 1/4" square key and two 1/4"-20shcs. To make advantage of the screw body, and even more so to assure

location I drilled undersize pilot holes in the vise body and then in

assembly drilled with a nr. 8 drill though both parts, following with anF and tap.

The movable jaw is one piece but the rear portion might as well be

pinned and screwed on to simplify milling the recess. The nut is made to

fit the lower channel and jaw recess, and drilled clamped in place at

the same time as the clamping screw hole with a long drill. Instead of a

fiddly loose pad the cylindrical insert is just a 1/4" dowel pin with aground flat, lightly pressed in place so it can self align with the face

on the nut.

I used a piece of 1/2" rod for the screw, and pressed a 5/8" collar ontothe end to bear against the thrust washer. The cast iron washer is press

fit into the housing with some grease and the screw, holes for the 2-56

shcs drilled in assembly like with the fixed jaw.

The base is sawn out of a plate that already had the stepped bore, and

the ears shortened on a lathe faceplate to clear hex bolt heads. The

clamping plate is cut off the end of a shaft coupling turned down to fit

the recess. Slots for alignment keys would complete the vise and base

but I haven't made them yet.
