Hi Lee,
i saw it and was tempted a bit but at the end decided from steel. This is may be the tool i use most and for everything / same for the 12" disc sander/ so i decided i would screw it very fast if not from steel. Plus the noise and vibrations when i sand 5 hours non stop. I looked at the 2 most expensive grinders and some nice builds which are proven designs and people use them from years.

Some update with pictures. I am actually making 3 machines, one for me, one for Jeff/ fellow forum member and friend, that lives around/ and one for sale. I think of that as prototyping :-)

Cut the steel and made some pieces:



Jeff cut the main pieces ,that had to be precise, on the mill. In future all will be plasma cut on my machine but as i still have not finished it...



So i started assembling this and that, welding , sanding and squaring:





people go at restaurant Saturday night , instead 22.00h i was still welding brackets yesterday. Yeah, i was using olive oil for protection of surfaces when welding, drilling and threading, so it smelled like in restaurant around here




sanding the bracket on my diy 12" disc sander made from 12" diamond disc welded to the pulley and 0.75kw motor.



brackets ready




the plate that goes on the bracket has 2 screws each, one side only, at the other side i sanded the weld and welded again until pits disappeared. not to speak of that even threaded the hole before welding, as i want all to be very precise




The machines without the face plates and the pulleys. tomorrow jeff wil bring me the pulleys, bearings and so, so only thing left is motor mounts . Both motors are 3 phase with VFD.





I think that will be one of the most used machines in my workshop, hence the idea to make it as good as possible. What do you guys think? You like them?
