Linear rod advice.
Hi All,
I am building a 13" x 13" cnc machine by precisely following a set of plans and instructions.
I would like to know if my linear steel rods can be replaced by hollow steel tubes. The amount of money saved is around half.
I would like to know if steel tubes can be incorporated into a cnc machine instead of steel rods.
Has anyone ever seen a linear steel tube with bushing in a cnc before?
Thanks.
Alex

Re: Linear rod advice.
Hi Alex
I would stick with the hardened steal rods as they will keep your machine more rigid, where as hollow tubes do tend to bend a little.
Hardened rods are only around £2.00 for 100mm depending on the thickness from certain suppliers.
Good luck with your build
Cheers
Sean.
