Will do, thank you.

I would have thought that the inverter is going to run at near maximum load most of the time. I was always taught to spec equipment 25% higher than the maximum running draw. That way machinery will never be running flat out. Also maximum and minimum power outputs are normally measured under ideal conditions.

I will post some pictures tomorrow. They are cut in a straight angle ( I have clocked them to confirm this) rather than a helix and they alternate lefthand - righthand so that they mesh. But because of the angle they have thrust washers on all the gears.

Lego are the biggest tyre manufacturers in the world.

I am rebuilding a 1914 petrol engine that has twin cams. One of the timing gears is missing. I need to make a replacement, I have measured them and they appear to be cut at an angle of 14 1/2 degrees but are straight not helical.

I assume I can cut the gear the same as straight spur gear but at the correct angle.

Anyone has come across this type of gear before?

Amazon sell an unbelievable number of dangerous chemicals and they will post them. If you know the right components you can even buy them to make your own batch of nitro-glycerin!

When I have soldered tanks including petrol tanks, I seal them and use a pump to gain a bit of negative pressure in the tank so that the solder gets sucks into the joint.

Yes no problem. The hardest bit is grinding the form tool. Using a rotary table or dividing head won't present any problems as long as you have a bit of clearance after the tool clears the job.

With regard to the lathe accident I was always taught to always put a centre in, if the amount sticking out exceeds the amount being held. Even when you are facing the material!

I was led to understand that EN stood for Emergency Number issued by the Government in the last war due to steel makers had all their own grades.

Why not use a 22mm bullnose cutter?

Drag racers race suits are similar to donkey jacket material, I assume this is for insulation in case of fire!

A heavy leather apron will protect you against red hot steel for about 30 seconds. Proban overalls will last about 3 seconds if your lucky. Most Proban overalls have a fire rating to stop catching fire rather than protect you from burning yourself.

A Proban Formula 1 race suit is rated at 60 seconds and a standard MSA suit is rated at 10 seconds! The theory is it gives you enough protection to get out of the car and run!

The problem is what ever you wear might stop you burning but it could help cook you!

I need to cut a SAE 10 spline and I need to find a supplier of spline form cutters. Anyone know a supplier in the UK?

When making wrought iron twists for gates and railings, you should twist the left hand ones one way and the right hand one the other way. This way they look much nicer and is the traditional way.

-40 Celsius is the same as -40 Fahrenheit.

Anyone know what speed Singer motors run at flat out? I was thinking of using one for a toolpost grinder?

`Like a coil spring. On large sizes I use a powered pipe roller but I need to some in 1/4" copper.

Anybody know where I can get a set of drawings for a small bore spiral pipe bender?
