Thread: The Workshop Progress Thread (2016)

John Pace:

Thanks for the further information about your keyway slotter; having looked at your photo I see what you mean about getting the thrust directly behind the cutting tool. I think my device may have been loosely based on a photo in Len Mason's little book Using the Small Lathe. I recently used it to turn a number of steep tapers - much quicker and easier than twiddling the topslide handle.

When I made my Quorn square holder I adopted the alternative method of welding four lengths of flat bar together and turning the outside with the job held on a square mandrel.

I hope you will keep us informed of the progress of your shaper project

Roderick Jenkins and John Pace:

Here is my version of the topslide slotting attachment:

Made many years ago and I don't remember the source of the idea. There is no illustration to go with WE68 in my copy of the Plans Handbook but it could well have been based on your design. The short length of garden hose has proved an acceptable handle.

So it's the worm that turns sweetly?

Am I right that no one has mentioned the point made by GHT about Griptru adjustment? He devoted nearly two pages to the subject in his MEs Workshop Manual, the central (!) point being that he counselled easing off and re-tightening the body screws before and after adjustment.

Thread: How far would you go?

I have a faint recollection of an account of some early racing car, possibly one with an aero engine, that needed a flywheel. The makers located a large billet of suitable steel in a scrap yard and sent two lucky people armed with hacksaws and instructions not to return until the necessary slice had been sawn off! I think they were there for some days.

Does this ring a bell with anyone?

Your motorised trike is somewhat reminiscent of my (more recently completed) Speedy.

Thread: Quick change tooling

Tractor man:

Many thanks for taking the trouble to describe and illustrate the Arrand tooling.

My impression is that few of these were sold by the maker on account of the perceived high price and that fewer still are sold on by users because of their real worth. As to the difficulty of making, have you considered whether the individual carriers are too demanding for the ME to reproduce as opposed to the lever-operated holder which fits in the tailstock?

For many purposes this arrangement seems better than a tailstock turret.

Michael Gilligan:

"Breech Lock arrangement" - the lever does rather suggest this. Where's Ruby Loftus when you need her?

There is something to be said for using genuine cartridges for the warranty period.

Tractor man:

Thanks for the photos. I, too, would like to know the working principle of the Arrand tailstock tooling. Did it come with any drawings that you could share?

Thanks for the Lubuntu tip. I will try it on my old netbook which is now rather slow under Ubuntu.

Is your Canon a current model? And are all its features supported?

I have found that an otherwise OK printer can become less useful when there is no dedicated driver for the latest OS and you are limited to the in-OS driver with much reduced capability.

I agree it's similar to the hooks used in mills for handlng sacks but they have a sharper hook. The other end seems to be a screwdriver blade.

Might it be possible as a temporary workaround to rewire the switch so that reverse gives forward?

Thread: Metric lead screw on a Myford Super 7
25/01/2016 11:15:56

I see that Michael Gilligan's 10 has top slide and cross slide feedscrews threaded 3/8" x 2mm pitch to go with its hybrid leadscrew.

Also interesting that John Caines' handwheel has intermediate markings which omit the leading zero eg ".2". Is this normal practice for metric leadscrew handles?

Thread: Boring Bars.

Further down the Dorian document is a better view of their favoured split collar. A refinement on this was used by GHT as seen on the left in my photo ie a small stress- relieving hole; the other holder is a simpler version without the eccentric bush seen on the left. Proponents of other methods sometimes ask what the standard flats on the bar are for, if not for clamping? The flats do facilitate other methods but in my case the top flat just serves as a reference to the correct radial positioning of the bar in the holder; I have added a cross hole in the smaller bar which takes a tommy/sighting bar for setting the position.

Thanks to KWIL and tractionengine42.

The Dorian document seems to be particularly to do with deep holes but, FWIW, I agree with the latter's comments.

Interesting, but what is the source of the posted material, please?

Vic:

My stops have shortened ratchet handles; tool-free but the handles sometimes clash and require re-setting.

BTW, my X axis tee slot doubles as a mounting for a digital scale.
