You can't fool me, that's all your own work. Jack doesn't really help you, he just watches - I can tell 'cos the spanner is too big, and it's worn out; it wouldn't undo a nut! :)

DMIOM:
Jack's holding it that way because he's just used the screwdriver blade on the bottom of the handle to tighten those slotted screws which hold the standard onto the base! (and, you never know, the 'blind' side of that spanner might in fact be some sort of pin-wrench?

Thanks Chaps

On with the next bit I seem to be settling into a routine of scrapping the first attempt for various reasons and getting it right with the second.

Fist op was to turn up a blank in the lathe and drill and ream the valve bore 3mm.

Then keeping the blank in the chuck transfer the whole lot over onto the spin indexer.

Then mill it up into the oblong shape.

Then to centre the mill up on the part in the x and y and using the indexer to manipulate it to proceed to drill and tap the part to the required sizes.

The transfer the whole lot back on to the lathe and part it off to length.

That it job done.

As the assembly is getting a bit bigger Jack has enlisted the help of his apprentice Liz.

Cheers

I've only just realised that I've missed off some features from two of the parts :doh:

Putting that right will be my next job.

In the mean time I've completed some more parts the main bearings.

Again I started by turning and drilling a blank on the lathe.

Then manipulating it in the spin indexer mill it to shape.

The drill the holes.

Then back onto the lathe for parting off

I've used a catch wire to stop the part flicking off disappearing to be collected by the shop GREMLINS :scratch:

These are the finished parts

Cheers

I really like the idea of a 'catch wire' when making small parts - I'm going to tuck that one away in what small amount of grey cells that I have left :thumbup:
:clap:
The idea of manipulating it in the spin indexer is also a very handy idea - ensures reasonable right angledness in a short set up time - I like it.
