I'm back at work tomorrow (had 2 weeks off) so will begin machining and turning (in my lunch times) to make a skate-o-rail housing to test the theory! Been doing more draughting today, looking to support the 1" NB pipe by welding to 40 x 40 angle and also to put a 6mm steel web betwen the 3/4" gantry rails for support. should stiffen things up a bit!!
