Rejected Because: I thought that adding an extra bearing I'd avoid the racking I was seeing with the homemade CNC Machine - I was wrong

Here's a shot of the four linear bearing trucks I made last night - came out pretty good... Basically I wanted to have room for 6 bearings so that's what determined the length of these (which is 100mm by the way) - the T-slot aluminum is 60mm so these hang over the edge by 20mm on each side... I'm figuring that's not going to be much problem - but we shall see... The next picture is the over all shot and then a close up of trucks installed, and finally a video of the gantry moving :)
