2+2+3 More Plasma builds, double the joy ! 3X2M and 2.5X1.5M cnc plasma build.

I did see roller pinion when it got out, but the prices were higher than a THK ballscrew so i never bothered with it again, it also does not last as long as THK and can ot withstand the forces the THK can and makes huge amounts of noise while moving etc.
"servo belt" (nothing servo about it) is simple to make (buying it is also extremely expensive for what it is) it is quiet and works as advertised.

Sorry guys, been busy building this:

Alone!

Are you extending your workshop Tom? I have a bunch of (for one reason or another) not used galvanized I beam columns you can have if you need them. Shipping cost from Australia might be a problem tho.

Yes, unfortunately i can not extend it with concrete and bricks as the rest of it as it might get demolished next spring, by the looks of it, with the house and everything, to make space for new buildings.
Thank you very much for the offer, but shipping to Kosovo will cost much more than buying new.
That is where i will have to put these two new machines, outside in the cold ... or hot as it can get over 40 degree C here during summer. 2 or 3 years ago the temperature was -27 at night for over a month, and the lowest i remember was -38, caused some trees to crack !

Btw i did mount the beams, alone:

I am a stubborn P.O.Sh. i hate asking for help.
Those are 5.2M long, but was quite easy to get them up, lift the heavy side first then the lighter side while climbing the ladders.
