Thanks for the inputs. It was not the 1.5kW main spindle motor I was talking about sequencing, but just the little 24V 0.8A gearbox shifter motors.

We decided to implement 200ms delay between energising relays. It seems to work really well:

I always thought that it could help in handling frost as being colder it would roll off to the lower area. The Incans had agriculture set up like that crops raised to protect against frost!

Here is a good youtube channel where you can laugh while you learn things. I like watching his channel.

Well I ordered some cheap relays and attempted to make a buzz coil but couldn't get them to work. So I figured what do I have to loose I opened one up to see. Seems the spring pressure on the contacts was to strong and the magnetic coil was to cheap to react fast enough for them to work. So I did a little tweaking and made the gap between the magnetic coil and contact carrier about half and bent down the normal open contact to get it out of the way and now they work like a charm. Here is a video of the process.




And here I am playing with one that I modified and made a small Jacobs Ladder LOL.

.....I discovered professionally made knife forges complete with high pressure burner (which I know now is just as important as the lining) that will also get hot enough to forge weld for about £130 sterling, so I think I would now go down this route...

Any links/pointers on these ones? I might jump on one before Brexit.

Definately a bit more research on my part before starting the project would have helped but I was just too excited to get started when I found an empty calor gas bottle in a skip

Never underestimate power of exitement! it is important to get some positive experience or interest runs down fast. Rather few failed blades than two years of relentless recearch before buying one too expensive equipment and then to find out that "I actually need a little smaller one".

Here is similar to what I found and there are a few different types on offer too.
this one should not be effected by Brexit for you Pekka

Impatience is a trait of mine unfortunately Pekka lol and after visiting AdeV at his workshop I feel very under equipped and now also feel the need to by a milling machine amongst other things
