Milling on a Lathe with a Vertical Slide

The SOBA vice in your link is the same as in Jasons pic. If you search Chronos for small milling vice for Myford you will get a choice of 4 pi x. On of them clearly shows the mounting holes in addition to the 4 edge notches. The only variant in Jasons pic is some nuts replacing the knurled end of the operating screw.

Awesome, thanks for the clarification, I’ll get one ordered up. 😂

So I ordered the Small Soba Vice and I have now fitted the Vertical Slide.

Here is the vice loosely installed:

The problem is the T nuts that came with the vice are not beefy enough and the bolts are Hex Head and don't fit through the holes provided!!!

So spend a few pence on allen head bolts, and file new T-nuts out of some stock.

Of course, that’s what I’ll do, but why would Soba supply bolts that don’t fit?

I am happy with measuring the Allen Bolts, but I have no idea how to measure and get the correct T nuts?

Now that you have jury rig, you can now make your own T nuts! And a load of other things, as the need arises!

Have you considered turning the vice through 90° and putting the bolts through the slots provided on the outside edges?

I would measure the end of the T-slots. Probably with a rule, as the nuts don't need to be a machined sliding fit. Hacksaw and file job.

TBH I think the nuts and bolts supplied are designed for the slots 🤣

The bolts will probably be too long to use with the heads recessed if they are intended to be used in the outside slots.

Bill, do as Nicholas suggests,, turn the vice 90 deg, make/get T-nuts to fit the slide and bolt through the two counterbored holes in the vice with allen bolts. This arrangement will allow you a good range of vertical travel by selecting an appropriate slot on the slide.

[Howard LewisParticipant @howardlewis46836]

To find what size T nuts you need, measure the T slots on the Vertical Slide, and then make nuts a little smaller (So that there is clearance ) 0.1 mm clearance on each dimension should suffice. The T nut must not match, or protrude above the surface, or it will not clamp.

Beware of the stud / bolt going right through the T nut. Centre pop the threads on the underside of the T nut to prevent this.

A bolt or stud going right through could result in cracking the T slot, by contacting the bottom of the T slot and forcing the T nut upwards against the top,of the slot.!

You have Drills, Taps, the Vertical Slide and a Vice for for it, so you have the kit to make your own T nuts,

So i turned it 90 degrees and it is secured using the outside slots. I'll measure up the counterbored holes and the T Slots in the vertical slide and make up some T Nuts and order some allen bolts.

With the cutting tool I am making in the jaws I get about 95mm of space in which to have the work piece I am machining. The object I have in mind is around 80mm so that should be good.

[JagerParticipant @jager]

Hi Bill,

Pleased to see you are getting there.

Don't forget you can also take the vice off and clamp your work directly to the slide. It's handy if you just need that little bit more room or your workpiece is an odd shape for holding in the vice.

David.
