1220 × 2440 build

[Boyan Silyavski]

When all is short , it looks very sturdy. In 3m length even the 100x100 box section feels like makaroni. If steel, i would say gantry will have to be minimum 100x200x3 beam at the very least. So for aluminum i dont know what Dean uses, but i think 2x 90x180 in L configuration will do the job.

If you want as cheap as possible you have to do all from steel. There is no escaping that. The bigger the steel you use, the simpler the structure will be. 100x100 will need no diagonal bracing, if done right. If you get your hands to 100x200x4 or thicker, that will simplify greatly the whole build. 100x100 is the maximum a Rage saw can cut, hence the maximum you could cut at home.
