Ready Steady Eddy

[JoeHarris]

Thanks Boyan, and yes that description was useful. My issue like yours is a lack of specialist kit. I was asking eddy as he has built in aluminium. I am ok where the aluminium is being mounted in such a way as to make the most of the cast sides as these are nice and flat. But the edges are not and neither are they square. Also the ends of the extrusion I have is not quite flat/square so it makes squaring the x and y to each other hard to achieve. I think I have resigned myself to needing a surface plate and some blue and just scrape the parts square. It's the only way I can think of doing it without a mill... Getting the long axis rails parallel scares the crap out of me!
