    not quite sure where im going to put the Y stepper... should of perservered with drawings.. but too impatient.

    seperately, i have been given literally 2 tons of metal off-cuts. Its mainly 4mm and 5mm plate but some 3mm. all funny sizes but cut with machinery so all square. I think its galvanised?

    anyway ive got far too much, and it was free so If anybody here needs any, come collect it. (leicester) The photo doesnt do how much ive got justice my estate car was on its arches with three loads. There is loads.

  3. I have been looking for some scrap metal to practice welding but I guess galv isn't ideal? Not sure? I begged some scrap from a local fabby but have nearly run out...if it's suitable for arc welding practice I'd gladly take some off your hands!!

  4. Love the burner btw !

    If you've got the ballnut mounts from Chai they'll look nothing like the diagram he's sent you. They'll just be a steel block which you may be able to thin down the 86mm to less than 60mm. I dont have access to mine from Chai at the moment to get exact measurements but would say its deffo possible.

    You can probably just saw off the two flanges then drill and tap some holes in the bottom, then it'll be 52mm wide.

    Here's some I made earlier...I've got one left if that's any use to you? I just copied the dimensions of the ones on eBay.
