The star wheel latches round once very revolution to let you face, especially useful down a hole. It's not just a clumsy hand wheel.

The lathes database **LINK** Shows that the hyphen disappeared sometime around 1960


Edit:  Too slow yet again!

Thread: The Workshop Progress Thread 2020

Jason mentioned my Farm Boy. It's been put to one side for the moment as I have been playing with the brown stuff. I've been getting on with my Chitarrone - carving the roses has been a bit of a stumbling block but it's done now. I ended up printing 3D patterns and using them as a cutting guide.

Also making a Baroque Guitar, I've just finished the body, shown with the mould I constructed.

OMG... if Jason can't go to work he'll be producing 3 new engines a week! How will we keep up?

Seriously though, we appreciate your efforts yes

Keep well,


Thread: What are you reading?

Just finished rereading the O'Brien saga frown. The Rivers of London series by Ben Aaranovitch are good fun - police procedurals with added magic. I like the sound of Elly Griffiths, must investigate.


Thread: Does Silver Steel normally look like this?
19/03/2020 19:24:24

As Andrew says, square silver steel has been rare for years. I managed to get some1/8" square a considerable number of years ago. It looks like Chris's specimens, it's unground, and mine certainly hardens and tempers like conventional silver steel.

Does anyone remember the original Cadbury "Old Jamaica" chocolate bar ? I did the mould for that. Cutter was hand made Depth of cut around 2 to 3 thou...

I do. I'm glad to see that you didn't "knock it all back at once"

(sorry Andrew),


Thread: Coronavirus

Conspiracy or cock-up. I'm with cock-up every time. Interesting view on why these diseases originate in China on Youtube here

To precis: The Chinese command economy failed to feed its people. The government decided to allow unregulated private enterprise to provide food and, critically, announced that all wildlife be designated as a natural resource for exploitation. This led to the "wet" markets where all sorts of live animals are stacked cheek by jowl where they contaminate each other with their effluent, thus leading to cross infection. Although the food problem has been solved, the markets continue to be used by the well off who now treat the exotic meats as status symbols. In order to maintain their market share, the traders have also been at pains to exploit the demand for hyped up "traditional " medicine from various body parts of the exotic fauna.

I took the easy way out, buying one of these kcAAOxy4XNSOXKm"> from ebay.

West London factory, brazing, steel. Brompton bike hinge?


Thread: History of model engineers
18/02/2020 20:53:27

The whole model engineering thing as a popular hobby was really started by Percival Marshall, who founded both the Model Engineer Magazine and the Model Engineer Exhibition. His relationship with Bassett-Lowke and Greenly probably instigated the popularity of man hauling model locos. Names worth researching. Have fun!


Thread: Arbor for No.0 Jacobs Chuck?
13/02/2020 16:41:18

Just to confirm that 0 chuck takes a 0 Jacobs Taper. I turned one on to the end of the spindle for the drilling head on my George Thomas pillar tool.

In which case Dave, perhaps these pics will give some ideas:

I couldn't remember the Gospel, Chapter and Verse.

Nor could I but Google could wink

Thread: What bench drill
07/02/2020 15:58:11

When I bought my pillar drill Jet were the only ones to specify a run out on the quill. At least it gives you something to complain against. I'm actually very happy with mine.

Thread: Linked belt for Myford 7
07/02/2020 15:39:51

I'm very happy with the powertwist belt on my S7. As we often find, high power industrial practise does not always transfer well to our tiny, low powered machines.


Thread: How do I change the "default" lever angle on my Verdict DTI?
02/02/2020 10:20:00

The design of the T4A seems so different to other Verdict gauges that I wonder if it was intended to fit into a specific bit of equipment. The round body with the flush screw suggest it could be held in a hole so perhaps there was no need to change the direction or angle for its intended application.

Have you tried turning the screw on the side clockwise?
