Thread: Brazil Nuts [the dynamic behaviour of]
22/04/2021 09:39:57

I've noticed the same effect with dried fruit mixture. The banana slices are always on top however many times you try to get the mixed.

I think Steve's 5000 gallon tank was more to do with buoyancy rather than vibration.


Thread: chester champion mk1 foot print & working space?
21/04/2021 16:22:08

I have the Warco version of that mill (ZX15) and have it mounted on a drip tray 35 in. wide by 25 in. back to front. You do need another 8 in. each side though to accomodate full movement of the x travel but if you arrange it so that the table is above the height of the bench or whatever you have at the side you can allow the table to extend over the bench.

One big improvement I have made is to replace the single phase motor with a three phase one and inverter. Not only gives you easy speed variation but reduces vibration and thus improves surface finish.

Does it contain any information you need to keep? If not you could try formatting it on the computer that says it can't read it. Format it as NTFS if that option is available.

If it does contain important information you are probably stuffed anyway.

And remember that journalists were all those kids who failed math in highschool and took English instead.

They now go to a new university, take "Media Studies", and end up virtually unemployable.

Finally, one thing that always concerns me is the number of people claiming to know better than those paid experts. If those "know-alls" are so clever, why aren't they offering their services to HMG?

The trouble is that a lot of them are in government! That's certainly the case here in France, they've been totally ignoring the experts and as a result we have the highest infection rate in Europe.


Thread: VAT changes post Brexit
14/04/2021 11:29:33

I have the same problem in reverse. It is expensive and uncertain to have anything from delivered by courier from the U.K.  

Small items that can be sent by Royal Mail and are valued at less than €43 arrive here in France by La Poste with no fees or VAT to pay if it is to a private address. Doesn't help Fizzy though.

There's a handy little program on the website called NthreadsP which will solve all your screwcutting problems.

Thread: Anti seize grease on Myford spindle nose?
08/04/2021 10:53:44

I would have thought ordinary brown paper would absorb water and promote rust, a particular problem at sea! Perhaps the workshop stocked something like James Walker's Gaskoid which looks like brown paper.

The traditional material is gunge from the swarf tray...


Applied by loosing the rule for a few weeks under the swarf? smiley


Thread: Wire Gauge Drills

I believe they were originally based on Stubs steel wire gauge, not to be confused with Stubs iron wire gauge!


Thread: 1.1 kw brushed motor Torque
30/03/2021 09:54:34

If looking for a variable speed lathe I would want to make sure that it has a low speed range by means of a belt position change to make sure of enough torque available at low speeds.


Thread: Anyone done any Nickel or Chrome plating of mild steel parts at home?
25/03/2021 11:37:28

Years ago I did the nickel plating on the 1929 Morris Cowley shown in my album. I used a recipe that I found in a book from the University chemistry department. Unfortunately I no longer have the recipe. It used some nasty chemicals which were easy to obtain from an industrial supplier at the time. All was done on brass items. For it to adhere properly and last on steel you must copper plate first and you need a cyanide bath to do that well.

If I was doing it now I think I would go to a commercial plating firm.


Thread: A home-made gear - will it work?
24/03/2021 10:57:48

Have you considered 3D printing? I have used a 3D printed compound gear in my Atlas lathe screw cutting gear train for over a year with no problems. It was made as an experiment and has been left in place as it runs quieter than the Mazac gear.

Here’s a link to one ‘U.K. Supplier’ of such items: **LINK**


That looks to be good value. It doesn't have a servo though, it's an ac induction motor with an inverter. Nothing wrong with that but I do wish suppliers would describe products accurately.

Russell, that book looks like just what I need, so I've ordered it via Amazon.

Good luck and have fun!

Thread: Gasket jointing compound

It is not advisable use silicone sealant on your Austin 7 head gasket, that is if you ever intend to remove the head again.

Agreed, I used to just give the gasket a thin smear of grease. It made head removal easier for the frequent de-coke!

"Nonetheless, provided you know what you're doing, command line methods often faster to invoke and more efficient in operation."

Agreed Dave. When I first started using Linux (in the mid 1990s with Red Hat Linux) I spent many happy hours with the manuals and still occasionally refer to Blum's 800 page "Linux Command Line and Shell Scripting Bible".

The easiest way on Linux to convert images to different formats is with the imagemajick package. On ubuntu,

  • open a terminal with ctrl-alt-t
  • Type:
    • sudo apt update
    • sudo apt upgrade
    • sudo apt install imagemagick


convert filename.bmp filename.jpg

does what's expected - convert

Not sure that's the easiest way for beginners! Yes Imagemagick is a very versatile bit of software but is command line only. Perhaps an easier way would be to install Converscreen which acts as a graphical front end ti Imagemagick and will convert and resize almost any image format. Even works on Windows as well!
