Default A Little Workshop Project.

This is something I have been planning to make for years; I finally got down to it this morning...



This is a spindle depth stop for my lathe.

The main part with the two knurled wheels locks into the tail of the spindle, gripping the depth stop rod at the same time. The grey piece is a bit of nylon, machined to MT3 to fit the nose of the spindle - if a very long overhang is used it will support and centre the end of the rod.



The three main components: the outer fits into the rear of the spindle and has a taper inside its front end, the collet has a matching taper, plus a threaded rear end. The second, threaded, wheel draws the collet into the outer.

As the wheel is tightened, the collet grips the stop rod, whilst pushing outwards on the outer. The outer presses outwards and grips the inside of the spindle. Simples!

4 hours work for a job I have been putting off for at least 20 years...

I think I understand, but 'mandrel is confusing me.
Does this fit through the headstock spindle bore, forming an adjustable stop ?

Yes. Not sure what I was thinking when I typed mandrel. It sort of works, but of course I meant spindle...

I probably should edit the 1st post to save confusion.

The way that Martin casually knocks out such lovely bits of kit is a source of both amazement and no small amount of jealousy to me!

Super stuff.

Yes, can't you ban him or something Peter? Same goes for the Wolseley Phill chap as well - bad for group morale!

To finish off little jobs like this, I generally make one more thing...



A box! There is nothing clever, sophisticated, or even particularly smart about this - it's just a roughly made plywood box to keep the bits together and safe. Hinges, catch and some varnish still to be applied.

Nice functional case

Will it be lined with Green baize with a discrete brass makers plate in the lid?

Errr... No, and No!

P.S. I do have a Taylor Hobson pantograph engraver, and sometimes I make a label for the outside, to remind me what's inside!

Bet it makes a nicer job than my Brother label printer
