boxford Cross slide

Lock it off when making the cut.

Exactly, Richard. That's a modification that you might need to do HPS.

I cant lock it off there is no means! YET!
Nice Seadog does that just push on the gibs

 

[Seadog]

Yes. Since most of the time it's further forwards on the dovetails the rear gib screw is fine. Even so, it can foul the compound. That's why it's fitted with a long grub screw that allows me to adjust tge lever position. There's also a small O ring to provide friction to keep the lever horizontal when unlocked.

great Idea, What is the grub screw size and pitch is it 2BA or something similar? Did you make or purchase the grub screw?

 

[RichardM]

On the later X10 series you just nip up one or two of the middle grub screws to lock the cross slide, for the top slide it's the centre grub screw.

I wonder if the cross slide would be straight swap?

It's 2BA. I've a lot of them. Can pop one in the post to you.

Yes please Mate that would be a step in the right direction all I need to do then is turn a few little bits and hey presto I can lock the cross slide.

If you mean for the X10 - no.

 

[123hotchef]

I didnt think so!

I wouldn’t bother making something like that - needing shim-washers to keep the handle in the right place... I would just buy a suitable one of the adjustable clamping levers.

Shim washers can be side-stepped. You make a plain boss for the handle, tighten it up and then mark a suitable place to be drilled and tapped for the arm.

It will be difficult to find a Kipp-style handle with a 2BA male thread. Possibly use an M4 one with a female thread (small physical size) and make an M4/2BA stud to suit.

A big thank you to @Seadog for the grub screws. I quickly knocked this solution up to lock the cross slide. All I have to do is remember it's there now...

A little video for anyone interested.

I see they still sell the metric lead screw and nut for these old lathes. I presume mine is imperial but I guess the metric would be a straight swap if one was swapping the nut and screw?

 

[Seadog]

It is, but your graduations will be wrong. Unless you fit the DRO, then it doesn't matter

You cannot presume that it will automatically fit I have seen 3 different styles of Boxford slide screw and none would inter-change.

 

[123hotchef]

Presuming is likely to get you in trouble - especially when it is so easy to measure, to be confident tather than guessing. Are we now talking about the lathe lead screw - or still on the cross slide feed screw?

cross slide lead screw and cross slide lead screw nut, the lathe lead screw is a whole another can of worms!

 

[Seadog]

The confusion comes from incorrect terminology. The slides have feed screws. The carriage has a lead screw.

thank you for that I learnt something else today.
