Allistair, picture #4 tells me that you are very good at what you do. Looking at the welds in that picture tells me that you have taken welding to an artistic level. :thumbs_up:
It looks so beautiful! :thumbs_up: :thumbs_up:

cheers fellas!, sad to say , but i love welding!, i just wish i knew more about it!, im 27, but i started welding when i was 12. i never actually got trained, but just picked the brains of the old hands!.

i think we have made a few of them barry, but pretty sure they are hard as flint and un weldable?... no just re read your question, not the actual bush, but yeah, think we also botch welded the housing temporairly but it too is hard as hell and pretty much a no go.
i know we have deff made the new bodys before, prob for yourselves?

I can only remember one a few years back that came out of your workshop. I have seen a number of different repairs come in and none seem to stick the pace at all. And yes the steel is hard as hell! You want to try and get damaged chisel retainers out on some of the larger hammers. :doh:

here is another shear that broke the tip off the moving jaw. it was tricky as i had to transition the prep from both pieces. there were also multiple layers of plate that had to be removed and re welded

about 4 foot by 4 . ha ha , only jokin, we have a stack of welders, must be about 10 in that shop most of them are 400 amp migs. i prefer 1mm bare wire, the rest use 1.2 and a lot of flux cored.
and we run the all important gouger off a fantastic 750amp lincoln grey bullit. its amazing what the steel that you can shift with that beast!! it can handle a 13mm gouging rod but the 10mm is best to use

Like the other guys Allistair, I'm VERY impressed with your standard of workmanship :bow: :bow:
I'm curious to know what type of MIG wire you use for the hardened steel, presumably special composition rather than the "common'o garden" stuff I get for my home MIG ?
If I have to weld anything fancy, I use INOX DW rods and my stick welder.
