Guys

I am getting all the last bits of info together.

My planned build is a 1600x1000 gantry type mostly built out of extruded aluminium.

My concern is that even though i think i have the right sizes/dimensions alu for what is needed, i am not sure about the slot sizes or what the best way is to mount 15mm profile rails on them.
It would seem that you can get the same profiles with 6mm or 8mm slots.

If you guys have any experience with this, can you please help?


Thx

PS: Gary, thanks for the chat/help/info/prices/etc on the drive & parts.
