If you want odd bolts, try working on pre-war French cars! They made up their own sizes and pitches!

I have found the best paint is the ones that contain large amounts of lead. It goes on like a dream and leaves no brush marks.

I would get one fitted then you can ring when you want a cup of tea!

Hope not! He was a selfish alcoholic a**ehole!

The best way is to use solder paste. Machine both halves flat, coat with solder paste, heat up till it melts then wipe off with a piece of leather. This should leave you with a couple of microns of solder on the bearings Now clamp the two halves together and heat up to fuse the two halves together. If you use too much solder you will have to shim the bearing after cleaning up.

I work on Bugatti's and they use M7, M9, M11, M15 etc!

Most scrap yards use these now, especially on stainless steel and ali-bronze.

There is a lot of difference. I have seen steering arms made from en8 snap like carrots! I always use en16t or 24t and so far none have ever broke.

I always mark offcuts with number stamps so I don't use the wrong steel for the wrong job.

You would need to do a lot of cutting to get your money back!

Molten aluminium and water is highly explosive!

Owatrol oil.

It depends what temperature you will running at. There must be a formula for calculating heat versus strength of steel. The higher the temperature the weaker the steel becomes. The comes a point where you get a sudden catastrophic failure, that's why steel beams in buildings have to be incased in plasterboard.

Not a lot! Might get some of the big stuff, lathe and mill not much else. A couple of years ago I did a rough calculation of the value of my tools and stopped when I got to £50K. Some of my Stahlwille spanners are over £30 each! A Hoffman dividing head second hand will set you back £500+

It would be too hard to make a die and hammer them out as they are quite small.

They are normally drop forged,

EN3 is a weldable mild steel. EN1A contains lead to give better finish but is crap to weld.

This looks like a bargain for someone. Lathe

Meccano screws.

Start off slow and increase speed until it cuts without building up any heat.

Does anyone have drawings to make a universal head for a Clarkson tool & cutter grinder?
