Quote from the Hornby website/news 28/11/2012 :

Humbrol’s manufacturing has been moved back to the UK from China to improve supply, and ensure high quality standards continue to be met, but from an easier location nearer to the Margate Head Office.

When I was a lad, the Diana pistol was referred to as a "push and blow". Quite a good description of the way it launches the projectile I think.

Went today. The place had been rearranged from previous years. The building appeared smaller but there seemed to be more inside, excellent exhibits and more traders. Shades of Dr. Who perhaps? or just my imagination.

I have been using a toolpost and holders from A&R for some time with no problems apart from the bush supplied not fitting the toolpost stud on my ML7. Easily rectified by turning my own, but from the advert they now appear to supply a range of bushes. The post and toolholders are well made, I would recommend them.

"Time for bed" said Zebedee !!

It looks to me to be a Cowells Hand Shaper motorised in a most ingenious way, including the use of a Myford clutch!

Some serious thought has gone into this one.

Hi Paul,

This may help you with visualising shaper tool profiles.

There was an article in Model Engineer magazine by L.C.Mason entitled "A Universal Toolholder" dated 2nd January 1970. The design is very similar to that already described.

I have made a couple of these for friends who use them as "quick set" toolposts, ie they retain a single block and adjust the height for each tool as required; sort of halfway between fiddling with shims and a full-blown QCTP.

My observations are that there is no need for a large diameter height adjuster, I think I used about 5mm diameter with a fine thread for precise adjustment, a small knurled knob on top makes fine adjustment a doddle. I would recommend though that a brass or copper tip be fitted to the bottom of the adjuster to prevent marking marking the upper surface of the top slide.

The dimensions given are not set in stone, they can all be adjusted to suit the lathe. IMHO the main considerations are are a robust central post and a toolblock to suit the size of tools in use.

According to the photo's on Lathes.co.uk the shaper head is definitely a number 2.

Hi John,

Is this the sort of thing you are looking for?

Gordon,

I use this type of finishing tool in my hand-powered Adept.

I use a roughing tool to within a few thousanths of an inch of the finished dimension, and then finish with this tool taking no more than 0.001 to 0.002 of an inch cut at a time. The resulting finish has been remarkably good for such a simple machine.

Congratulations on your purchase Michael.

You will find that it is very cheap to run, and environmentally friendly !!!!

Seriously though, as long as you don't expect it to shift huge quantities of metal, it should prove to be remarkably accurate and give a good surface finish. I have owned a hand powered number 2 for some years and have found it really useful for some jobs.

There is quite a bit of information out there on t'internet about shapers in general. The beauty of the beast is that tooling is dirt cheap and easy to modify. It took quite a bit of experimentation to produce satisfactory tooling for mine, but I have been very impressed with the finish that can be attained on steel, brass and aluminium.

The frontage of the old Sentinel Works still exists in Shrewsbury.

Liquid hand soap and sugar. (A bit kinder on the skin than washing up liquid despite what the adverts claim!)

A fair selection of de-greasers here:-

Greetings David,

I was always under the impression that the W was not an upside down M but stood for Weston Engineering who produced the original Myford toolposts and holders.

Oops! Sorry Charles, got that one wrong. Try the Dial Gauge Contact Point Set on this page.

Ronald,

As I understand it, the jaws should be pulled outwards as close to their ends as possible when grinding to overcome the effect of "bellmouthing".

I have constructed the contraption shown, and so far have attacked 2 worn 3 jaw chucks with very satisfactory results.

Greetings IVATTLMS,

I believe that the "W" stands for Weston Engineering who made the original Myford quick change toolposts.

There again, I stand corrected if I have been misinformed.

Gordon.
