Thread: Making a Carriage stop for a lathe
05/03/2022 17:36:07


That's a very nice looking machine and ingenious solution.

On mine, the corresponding hole is for the detent grub screw ie FWIW not an oiler.

... I remember by boss who was responsible for interviewing prospective candidates for the electrical department telling me a candidate had signalled his membership to him which in that situation is forbidden, as you are not to use freemasonry to your personal advantage...

This would be equivalent to canvassing which job adverts used to warn would disqualify.

Regarding the gearbox, this is the earlier pattern with the shortened lead-screw driven on the right-hand side of the box. I gave the screw a double-length key-way for the pinion so that can be drawn out of engagement, avoiding having to wind all that machinery round when using the lead-screw hand-wheel.

I have the later gear box whose selection lever on top of the box has intermediate "neutral" positions. I assume from your ingenious modification that the earlier box does not have this feature?

Cillary Blue are a good company who make new lenses to your prescription and fit them to your old frame.


Edited By Alan Jackson on 01/03/2022 10:49:21

Thanks for this tip. The big players who won't reglaze should think on. The rot started with the fad for so-called designer frames.

Given that frames now come in a seemingly infinite variety of shapes you do wonder how CB go about getting the lenses to fit.

Thread: Number stamps quality.
27/02/2022 14:48:59

Most of mine are by JHS MODELMARK and are pretty good.

It helps to use something like GHT's UPT jig which would allow a faulty stamp to be rotated about its axis.

That said, I am sure that folk with plenty of practice can achieve good results by hand and eye.

Thread: Hand Hacksaw

Could we extend this thread to 'junior hacksaw' selection?


Eclipse do one with a tensioning screw.

27/02/2022 11:16:31

As a convert to the Japanese-style pull saw for wood, I wonder whether there is any merit in reversing a hacksaw blade so as to cut on the pull stroke?

In theory, tensioning would not be essential and a pad saw handle could be used in this way.

Incidentally, I remember someone repeatedly breaking blades on a job only to discover that he was putting them in the wrong way round!

Thread: I want chips

Gary at EE ground a chip breaker on the tool used in one of his videos. Try asking him for details or just experiment.

Thread: Parting tools and inserts
24/02/2022 11:05:33
Posted by John Reese on 24/02/2022 00:11:21:

I have experienced mixed luck when using carbide insert tooling for parting off. I have HSS parting blades for my 10" and 16" lathes. It is nice to be able to take it to the grinder and put a slight angle on the cutting edge to eliminate those nuisance pips from the cutoff part.

I suspect that many of us have had mixed fortunes in parting off!

Sandvik, and no doubt others, do offer inserts with angled edges designed to minimise pip.

Good advice above and you may be able to correct the ER taper afterwards if necessary.

Thread: Making a Carriage stop for a lathe
20/02/2022 11:20:58

I haven't yet viewed the OP's video but here are photos of my own very simple and long-established carriage stop for the gearbox Myford:



A previous owner had put a tapped hole in the bed which provided a mounting point and I have stop rods in varying lengths to suit the job. A split collet would be more elegant than the clamp; I don't recall testing its yield point in a jam-up.

Thread: Aluminium casting - making a smooth surface rough by blasting.

Thanks for clearing that up and for the fascinating link. I wonder whether an air-operated needle scaler would do the same job - possibly not small enough for model work.

I try to combat brain fade with the odd mnemonic; Wolf used to advertise their grinder pictured alongside a file and the slogan "Forget it - Grinderette it!

Wasn't there something about sending ebony to foreign countries?!

I've had better results texturing the smooth parts first and then you can blend it in by blasting. The old "Wolf Grindette" is the ideal tool at model sizes though small areas can be done with a handheld dot punch just tapping it onto the surface. If it's a big engine then a needle gun would be better.

Did you mean the Wolf Grinderette (sic) 4" angle grinder?

Wouldn't any small angle grinder do the same job?

My old Grinderette is still going (on its second set of brushes).

It's normally possible to drill and tap the MT end for a screw-in tang.

Thanks for the tip - I did know of it but find it doesn't always work for me.

Thread: Magnetic Lamp

duncan webster:

Thanks for the warning. I wonder if they are legal in UK?

I, and I believe many others here, have the IKEA LED lamps with flexible stem. Do you happen to know whether your point applies to them?

Thanks for this which is presumably of most interest to Chrome users.

I appreciate your practice of "spelling ou" the link as I like to know in advance where I am going on the web.

Thread: Tee slot clamps similar to mole grips
10/02/2022 11:00:38

If you are using one of these in a tee slot, I would recommend interposing a thick flat washer; the mating surface on mine is far from flat.

Posted by old mart on 05/02/2022 20:12:45:...I was cutting 40tpi today and waiting for the threading indicator to turn through 24, not 4 divisions as on Myfords....

When cutting any multiple of 8TPI on the Myford you can engage the leadscrew at any point - no need to wait.
