DIY Build of Aluminium CNC Wood Router without Workshop & Tools

[WandrinAndy]

Apologies for chopping and changing like the weather... In mitigation I have never built anything out of alu, so reckon it's best to get the design correct-ish up front in the virtual world. My fault is being far too hasty in posting newer versions!

I have further rationalised the frame material used... Have got my head around bolting plates at 90deg so am rid of the unequal angle profiles. Main materials are now KJN 45x90 alu-extrusion and Cut-To-Order alu-plate from Aluminium Warehouse. And the frame is now far easier for me to build and assemble.

Have also decided to go with profile-rail on the X-axis... Am more than a tad worried about the rising costs, but suppose in for a penny... and if a job's worth doing...

Although some relatively minor tweaking will be needed once I get into the Y and Z carriages, I am finally well pleased with the frame and won't bore you with any more iterations of it.

Quick question... my supports for the BK and BF blocks... made from 20mm plate... do these look strong enough... particularly the BF side that is not braced?
