Definately a scrapyard challenge

Right, here is redesign 5-1.

Obviously I will need to figure out the best side pieces for the gantry. Am I, sorry, are we heading in the right direction?

are we heading in the right direction?

You've gone for a pretty generic arrangement now, which is fine.
It will be stronger to put the bearing blocks for the Z-axis on the Y-axis and the rails on the spindle plate. This sort of thing (mine):

Between you and mocha I have a pretty good idea about how to progress.

Time spent discussing his machine was well spent then.

Hi Bruce,

I meant one of these to keep your re-design work to a minimum. But what you've since drawn is also good.

Routercnc - Thanks for that. The latest soluton allows for the screw nut to travel between the rails which keeps the overhang to a minimum. Apparently I still have a bit more work to do on that.:whistling:

Chip - I realise it may be a bit belt and braces but what I have learnt so far is that strength is paramount. The back plate will assit in the end supports and reduce any rotaional force on the boxes....maybe

Thanks for the comments guys

Forgot to mention i order the cabling. I dare not order any other materials as there is still time for a few more designs.
