Aluminium CNC log.

this is my fair bit of Alu, that's a 50cm ruler next to it and I got it for a stupid price.

it would be unfair to tell you the price due to pure jealousy, but you can guess at it :)

it's all 12mm thick also.

I will be drilling some holes later, but I need an engineers square to be really accurate.

So if the ruler was a stupid price how much was the aluminium? Looks like about £31 worth to me...so I guess a stupid price would be £20.

You seem to have laid it out with the Z-axis rails mounted to the Y-axis slide, not the other way round. Was that just for the photo? Putting the rails on the Z-axis so they move up and down and the bearing blocks are fixed is stronger.

the ruler was £1.29, £20 is bang on.

I'll give it ago with the rails the other way around, it's just I thought the extra weight would be a problem.

Jon, your awesome.

that's two birds with one stone right there.

the piece of alu I bought for the gantry was too thin by a few MM, mounting it the other way means it can work.
