Bear in mind chaps that we are talking about a hollow drawbar here with an internal thread on relatively thin walled tube. I'm not close to my Pultra at the moment so can't measure the wall thickness or comment on the hardness of the Pultra supplied drawbar.

Rod

Edit: Dell , Out of interest, what is the diameter of the Pultra draw bar?

Being completely free, having a comprehensive CAM function and being usable on a Windows machine adds up to a lot of plus points for many people.

From the Autodesk website:

"Fusion 360 for personal use:

Free CAD + CAM software for individuals who are doing hobby, non-commercial design, and manufacturing projects."

I don't I imagine that Autocad would do anything other than approve of authors showing how good Fusion is in a publication. If, however, the author was using Fusion to design a pattern that was then 3d printed and used to cast a component that was the sold then that might be a different issue. There used to be a limit on turnover for commercial use of the free offering but since they cut down Fusion for personal use that seems to have gone away.

Incidentally, I have just had to do a 3 year renewal which meant starting from scratch with the installation software but as soon as I entered my details it knew who I was and all my old drawings were still there (most, of course, archived). Why was I doing this? So I could design and 3D print a 4" to 3" dust extractor hose adaptor

Always assuming that Mortons wish to continue supporting the forum...

Do any of their existing magazines have associated forums?

No.1, the 4-2-2 8ft Stirling Single, featured in tonight's repeat of Miles Kington's "Steam Days" currently being repeated on BBC 4 and iPlayer.

When we moved house and workshop three years ago I packed most of the hand tools, machine accessories and other gubbins into a variety of wheeled tool chests. Whilst most of the drawers are themed there are, inevitably, quite a few drawers with an eclectic mix of miscellaneous gubbins. A year ago I decided I needed my Record "Imp" vice. I went through every drawer (and a couple of boxes) twice and could not find it. I came to the conclusion that I must have left it in the old workshop (as seen in my recent post of my Pillar Too). Last week, while looking for something completely different I came across it lying on its side in a shallow drawer - hiding in plain sight.

The point of this ramble is to ask the question: Why does my eye/ brain not see what it is looking for? Is it because my mind's eye sees the vice upright and fastened to a bench and doesn't recognise the recumbent vice as a vice. I don't know but it can be infuriating. Mind you it did encourage me to make the instrument makers vice from the casting I've had forever (and could find).

Keep at it guys.

Rod

Agreed. It is quite exciting

My choice is the pillar tool. The castings came in the large box of bits when I bought my lathe.

Having been only a signed chit away from a MOD stores for most of my career, one of the materials we used to use was Apiezon Q compound - a black putty suitable for use in vacuum systems. I guess this could have been (mis) appropriated by the machinists. It was probably quite expensive but we would never know that.

Rod

I interesting word, lute. As well as the meaning we are discussing it is also a musica! Instrument and a u shaped tube fi!led with liquid used as a pressure relief valve. None of which seem connected to each other.

Rod

Great stuff Jason. How did you locate the axes zeros after rotation of the stock to machine each face?

Cheers,

Rod

I suspect it was spelt "luting". Seems to be mostly a dental term these days but relates to puttys and cements so could have been one of those old school pre-silicone mastics.

As David says, the nut is used to extract the taper pin. I gently tap mine home. The tram can be adjusted if necessary with shims at the column split. I've had a small piece in mine for the last thirty years.

Mis-delivery is not necessarily totally the fault of the courier. We have had a lot of stuff left with our neignbour when we have been in. A few weeks ago I was looking at Google maps and noticed that the house numbers of ours and our neighbour's houses were switched (we are xyz and they are xyzA). A correction to Google was accepted and all is now correct.

I think Liilebullero rather than Lille Marlene. My Dad, as a graduate electrical engineer, was called up to the REME right at the start in 1942.

I suppose we can add Foo Fighters "monkey wrench" but not really about engineering.

Noggin End do small quantities of PEEK for reasonable prices **LINK**

4-2-2 or 2-2-2 ?

From the Blackgates catalogue:

John,

The Stirling single in preservation is the 8 footer 4-2-2 in the National Railway Museum, though I'm not sure at which site it is currently on display. Martin Evan's design is for a 2-2-2 and, sadly, I dont think one still exists.

HTH,

Rod

NSVT is a tank mounted soviet era machine gun...

Bear in mind that the chuck and arbor are sold separately. So, for example, Arceurotrade's two smallest chucks (keyed and keyless) can both be married to 2MT arbors.
