Giant hot wire cutter

[Boyan Silyavski]

Another idea. Google search for diy dolly track from pipe and rollers. You can hammer some round iron in the floor , say every 60cm, level it and solder the pipe, then cement below the pipe and form the flat bed at the same time. talking about 2-3cm of cement.





look how the motor moves it, its not necessary to be in the middle of it.

It seems even they sell ready wheels at aliexpress

So it seems from some pipes and fitting you could do the whole thing for a day, without soldering, i mean also the gantry.
