My baby 15" x 15" machine

[wilfy]

in re-designing i cant keep the shape of everything i want if i fully get away from the 60x40 box section across the top and bottom of the y axis bearings as i need the spacing of the 60x40 so that the y axis carriage doesnt bind against the y axis rails

a picture might help



if i change the top and bottom yellow pieces to 50x25 i cant see any way it will work without wasting a whole load of 50x25 and i'll be honest since dropping the 60x40 i'm cutting corners to try and get all the cuts i need out of 2 lengths of 50x25 @ 7.6mtrs
