The reason for 1250x1250mm is because it's half of the standard sheet size I use. If I had the room in my shop I'd go for 2500 x 1250mm. But it just won't fit. I'd prefer to get the best parts I can afford. To be honest I don't have a clue about the parts. I've seen so many different set ups it's confusing.

Think I'll sit down and draw up so designs and see what feed back I get.

Cheers for the advise.
