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.

the only thing with that is im not keen on just relying on gravity to hold it to the rail so I wound want a 3rd wheel at least but it would make a the long axis quite simple to do. The other thing as the base of the shed is timber boards so not reliable for direct fixing to much as it will probably move a little with temperature and climate

many thanks for all the idea
