Definately a scrapyard challenge

[motoxy]

Okay its sunday afternoon and I have spent an hour chopping wood. You know when you get what you think is a great idea. You rush in and draw it up and think...eerr i'm not so sure.

I was concerned about getting good fixings in the box even though it is 6mm. Rather then pushing tubes through I came up with the idea of prespacing blocks along a threaded rod and pushing it into the box. Drill through and fix everything. You then have 4 end bolts to clamp up the sides.

Your thoughts???

Just decided that that idea is pants. Think I may have a better one.

Probably just have a block fixed each end for location and fixing. Drill the opposite side of the box where the rail mounting screws are along the centre line just big enough to hold the nuts to lock the screws through the box. This should not have a detrimental affect on the overall strenght of the box.
I should probably now be thinking about buying some more parts. z rails and screw, motors and couplings. Then start getting some materials.
