    hi , i am mostafa from egypt and i did not built any cnc machines before so i was wondering if any one tried to build a gantry of 2 (20mm x 40mm ) v slot extrusion with length of 1000 mm before, this 20 mm x 40 mm extrusion size is the only i can find in egypt ,so is it suitable for a gantry?

    It truly comes down to how heavy of a spindle you are using and how you plan to use the machine. If you are using a small rotary tool and cutting soft materials, it should be fine. If you need something more substantial however, consider stacking three 20x40 sections and bonding them together into a 40x60 member. With a bit of creativity, a lot of screws and a couple tubes of JB Weld, you might even be able to pull off a passable 40x80 C-Beam. That should cover about anything over a 1000mm span.

    i was surfing online and i studied the shapeoko 2 cnc with 20 mm x 40 mm maker slide rail and i found a version of the machine with
    1000 mm x 1000 mm with spindles mounted to the 2 (20 mm x 40 mm) gantry and works fine , so i am thinking to build a similar body using the 20 mm x 40 mm v-slot rail , so what do you think about that? 1403193167_IMG_1671.jpg

    How well it will work really comes down to how you plan to use it. What do you intend to cut with this? How large of a spindle do you plan to use?
