Cheers Stu, I reckon I've spent just a smidge under £180 so far, as I'm making the rest out of scrap bits from work I don't think there's too much extra to come in terms of expense. I've an old PC that I'm planning to use, might get a 15" flat screen to save space. All the machining I'm planning to do myself, might pay to get the steel plates cut for me by one of our work suppliers, been quoted £17 per gantry side and £6 per skate housing side which comes to £130...but still might do it mysef yet. Will probably try the first one and see how it goes!

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!!
