Thread: Pesky Government Announcement!
17/06/2020 16:43:31

Well Peter G. Shaw. I am sorry to hear you are p***** off with the Government's announcements, intended to keep you and I safe.

Maybe you should spare a moments thought to the 49 members of the NHS who sacrificed their lives, so the likes of you could survive to be p***** of with the announcements.


Thread: A bit of history of Mach and LinuxCNC
19/04/2020 22:54:28

LinuxCNC, was formerly known as EMC2, which was the second variant of Enhanced Machine Controller, Linux-based CNC software.

And as MichaelG will no doubt be able to confirm:

In physics, mass–energy equivalence is the principle that anything having mass has an equivalent amount of energy and vice versa, with these fundamental quantities directly relating to one another by


E = energy
m = mass
c = the speed of light

What did you do during the virus war Dad?

Well Son, I had the most dangerous job of all.

I was tail gunner on a truck load of bog paper

Search on e-bay for "FG clutch". You can find the clutch bell (brake drum) and the shoes all for 52mm diameter.

I also know from first hand experience how careful Ford Motor Co was in naming its vehicles.

And then there was the Capri, which sounds the same as Capre, which is Italian for Goats.

Didn't they do well

That's a double edged sword. Traders being priced out of attending means such shows will no longer be viable and will soon cease to exist. Enjoy then while you can.

It would need to be 114cm if you want it to fit.

Ha ha, When I worked for BAE SYSTEMS we had a mad inventor guy who contacted us, offering to reveal the secrets of 'Magnets of the push kind' , which he had just invented, if we paid him a few quid.


Thread: KX1 CNC Mill Clearance Offer
27/02/2019 23:40:43


If I am not mistaken your hobby CNC mill is a big Tormach. I have tried to emulate your impressive feeds and speeds on my much smaller Emco F1, usually with disasterous results. We all get different mileage from our different machines

Slower is always safer and time is not money to the hobbyist..

Hello Jason

There is this strange desire, especially from newcomers, for all rapid moves to travel at the speed of light.

After 20 or more years using CNC for model engineering, I find that setting the maximum traverse speed to about 20 inches per minute ( 500 mm per minute) is more than adequate. The moves are well within my reaction time and they do not beat up the hardware needlessly.

Moderate traverse speeds and reduced axis accelerations are the best way to avoid lost steps and erratic stepper motor behaviour. The Sieg headstock looks to be a massive lump of iron to try to accelerate rapidly. So slowing down the Z axis rapid moves is a very logical solution.

Just read the Entry form, which answers my last question.


17/02/2019 19:10:05

That is excellent news. The Model Engineer Completion was always regarded as one of the most prestigious model engineering competitions in the world. I am so pleased the publishers have found a way to keep the old traditions and standards alive. The Doncaster venue is a logical choice even if it is a long trek for those down south.

Where will the completion entries be displayed, upstairs or in a section of the main hall?

Are you locking to accept 'private loan entries' as well as 'competition entries' as in previous years? That would give previous award winners a chance to display their stuff again.

Sorry no radial engine.

But I do have a part completed Revell Visible V8 which can be yours for a donation to your favourite charity, plus the cost of the postage. Send me a PM


Thread: Emco Compact 5
29/12/2018 20:36:53

Gray, Barrie and everyone.

Thanks for the advice regarding the plastic gib plates on the Compact 5 and other Emco machines. It is good to know that design is basically sound and does not need to be 'fixed'.

My machine is the CNC version with the lathe bed bolted to a sheet steel structure, it's not easy to remove the lathe to get access to the gib plates to make adjustments. So I attempted to make the adjustments in situ.I shortened a standard Allen key to fit, and with the aid of spot lights, inspection mirrors an a lot of rude words, I was able to reach up into the lathe bed to adjust the gib plate screws. Getting the Allen key to line up with the screw heads, when everything is upside down, back to front and barely accessible, was an interesting challenge in itself.

The three screws under the rear flat bed way, were already tight and did not need adjustment. The four screws for the forward gib plate, under the 'V' bed way, were a different story. One of the screws was missing completely and a replacement had to be found. The remaining three screws all needed about 3/4 of a turn to tighten the gib plate under the forward bed way.

These gib plate adjustments were difficult to do with the lathe bolted down, but possible; just. A complete transformation was achieved, the lathe and carriage are now correctly adjusted (for the first time in years) with no discernable play, even when I push and pull on the overhanging stepper motor. My Compact 5 CNC lives to fight another day.

Jobs a good 'un.

Thanks again for all the help, advice and encouragement.

Thank for your ideas.

I find the plastic keep plates will bend under load and the carriage rocks forward. It is quite noticeable on the CNC version when you push down on the stepper motor.

Has anyone tried replacing the plastic keep plates with brass or bronze keep plates


28/12/2018 18:27:45

The carriage of the Compact 5 does not have adjustable gibs like a conventional lathe, instead it has a pair of plastic keep plates which clamp ((loosely) the carriage to bed ways. There seems to be no provision for adjusting the play between the keep plates and the bed ways. As a result the carriage can rock slightly spoiling the accuracy and surface finish.

What do you guys do to reduce the free play between the carriage and the bed ways?

Have any of our Compact 5 experts found a better way of providing adjustment for the carriage to the bed ways?

Lanolin is a very good long term preservative for bright steel and other metals.

And you don't have to go to Arc to get it.


Indeed, just rub your Mamod on a passing sheep...

Quite so, proves the point. Have you ever seen a rusty sheep

I would go along with the choice of EN8 for the Gypsey crankshaft. It is a good compromise between strength and machinability. It is also readily available.
