Should I remove the compound slide

[striker]

A bit of advice needed, I've just got a wedge type AXA quick change tool post for my Chester db10 lathe. It's not a straight forward fit.
So my choices are to modify or replace the existing stud and bore out the bottom of the post, or do away with the compound slide and make up a solid riser block of Aprox 50mm. Apparently this improves rigidity. I have already done the 4 bolt baseplate mod to the compound.
I don't use the compound much, and I thread mostly with dies as it's easier than messing about with change gears!
So should I lose the compound or not? I suppose I can refit if needed for a taper.

A compound set at an angle gives you a much finer adjustment than without.

I've mounted my QCTP directly to the cross slide with a riser, and it's fine for most of the turning I do, and I just put the compound back on if needed.

replace the existing stud gets my vote, I did that on my Boxford. you need the compound slide.

I cant remember the last time I used it though!

really, I use mine a lot

Modify the post. Then make a riser to fit the modified post with the compound removed

Best of both worlds

Wouldn't want to be without the compound

Best of both worlds ^^^ however locking up the gib on the compound when not in use may be another option.

Yeah, I think I might keep it, modify the stud, bore the post and lock the compound gib when not in use.

cant you remove the exising stud?

It's pressed in from underneath the compound slide and has a larger dia than the M14 stud supplied with the toolpost. The compound slide also has a 20mm dia raised boss.
After a bit of googling, it seems the best method for this lathe is to open out the bore of the post to 20mm clearance and drill and tap the end of the supplied M14 stud to M10 so the (shortened) new stud screws onto the old stud with loctite.

I find that I rarely need to change tools when I do use the compound, which means I can leave the threading tool set up on it, which saves a lot of time..

Last picture doesnt show, seems to be a few image problems on here.

Lathe is similar to mine. I cant remember if I put the compound in the chuck or on an angle plate with boring head, but I turned the boss down to 15mm diameter and tapped it m12 for using qctp with compound. I bored out the bottom of QCTP but only about 0.5mm.
Most of the time I use a plate, the M14 mounting and a riser block, it is quite a bit more rigid.

Before I sorted out the mole hill on the compound slide top face as a quick temp solution I turned up a parallel plate that covered the whole top face . Had to grind /file off a bit of excess body shoulder that would have stopped the QCTP being rotated in any case and put a large hole in the plate to sit the new QCTP on , so the mole hill was contained in the plates hole .
