New Toy for the Myford

I knocked the do-dad in the rear QCTP tool holder in this photo to allow use of 1" shank tools such as roller boxes on the Super 7, it's just a length of bar welded to a length of tube, with the bar milled square after welding for alignment, then a couple of holes drilled, tapped and with grub screws fitted.

With a 1" parallel OD MT2 sleeve it also allows me to use the tailstock turret that's been hanging behind the lathe for several years, I machined the turret holders 10mm bore to accept my ER11 and ER16 10mm shank collet chucks on 10mm shanks.

The whole thing is surprisingly rigid, I bored one of it's own holders with it to see if it would be up to boring and turning – it is, and with a DRO setting for each position I'm hoping this will speed up manufacture of some smaller components,

Very smart Nick, any of those tools for putting an eye back in !!!

The nearest does both extractions and insertions

Interesting idea – I had to look hard to see what was going on in the photo.

How do you centre the holder?

The overhang of the TT seems rather large but I gather is not a problem in practice.

All the holes on the turret are bored using the turret's own locking positions so they all align the same relative to the taper – in theory.

Initially I just bored a 6mm hole in a bit of scrap and used a holder with a sliding fit pin in it and adjusted height (Y?) and X by eye and feel setting a DRO X for each turret position, so far I'm adopting a "Suck it and See" strategy
