    Yes, thanks much. My motor will be placed below the surface where the grinder mounted on, by using a pulley/shaft and pillow block bearings. Still waiting on parts to arrive, but I will post pictures of the project when I get started.

    Will

    Is the plastic container for keeping the VFD clean?

    If it is spec'd IP 66 the enclosure is dustproof.

    yes that is what I am aiming at, these grinder produce a lot of metal dust and that's not good for electronics. Since my grinder is portable the VFD is attached to the cart.

    Quick question. I usually simply tack weld "standard" nuts to the steel, but here you appear to be welding a round & threaded cylinder?

    It is a 3/4" steel rod cut in short lengths drilled out to 5/16" then taped 3/8"X16 after welding. I found many time welding a nut on you still needed to run a tap through due to shrinkage. I also generally tap the metal I weld the rod to at the same time for a longer threaded hole.

    Nice - thank you. Yes, I get your point about shrinkage - out of the 5x I recently Tig'ed, 2 got "really" tight!
