Im in the process of designing a gantry router and was wondering if anybody had a line on acme lead screw in long lengths. (I.E.) 9 feet. As you may have guessed i want to build an 8ft by 4 ft table and i want to be able to use ALL of said 8 by 4.Thanks for any sources anyone may direct me too! I assume finding a carrier that will handle something this long will be my first hurdle.
