I too only want to build the machine once so steel it is then.

Good choice.

Eddy' did you find any drawbacks in rigidity across the y axis with your open ended design? I was thinking it had to be a box type design but you have 100x50 box section on the X axis and nothing at the ends on the Y axis. I like this idea!

I've nothing to compare it against but I don't think it had any drawbacks in rigidity, here's some figures; http://www.mycncuk.com/threads/7155-...6572#post56572
Of course there's nothing to stop you putting something at the ends.
