    Can't wait to get the last couple parts in to finish off my build. waiting on wheels and VFD to arrive.
    I used 2'' hitch tube, as to not have to grind out weld seems and its a nice fit with 2'' reg tube.
    cant wait to throw some sparks!

    2hp motor should do the trick. :)

    Nice!, I've just finished my first 2 x 72 the other day using the same design. I have a second on it's way and is at the exact same state as yours in your picture. Using step pulleys, would be nice to have VSD like yours, and nice motor! I shimmed the 2 inch tube that holds the 1.5 tracking wheel tube with 4 strips of UHMWPE, nice tight fit and no need to lube ever.

    Nice grinder. I wonder how many of us are using Dan's plan for their grinder. I'm starting to collect pieces for grinder #2. Once the list of things to fix/modify on my first grinder got too big i decided it'd be simpler to just rebuild it. And of course, why re-use the parts and only have one grinder when i can find another set of parts and have two right? I'm sure the logic makes sense to all of you (if not your wives/partners) : )

    Ya that's for sure. With more then one you could leave one set up for one thing and have like a contact wheel on the other or wood with a vacuums set up one one and metal on the other haha

    got some more work done today with this beauty weather here in southern Ontario! got the grinder frame welded to the base and the adjustment tightening knobs on, and used a old gear I had for the tracking wheel adjustment, still waiting on parts though :(

    I have a toaster oven in my shop too :) Looks like you have good audio also. Trying to figure your welds out but hard to see in the pictures, what are you using? I wish my shop was that uncluttered.

    cheers, Rob

    Look at garage sales and online used sites for a Lincoln 250 amp Tombstone welder. They only run stick but short of dropping a dump truck on them they will run for ever and can be found for the $100 to $200 range.

    For small projects they can't be beat and in fifty years or so you could sell for more than you bought it or worse case scrap it for the copper windings

    Haha ya that's true. My dad did say one of his friends had his and wondered if they used it any more maybe I'll see if he can get it back but I really dislike stick welding. Tig is where it's at Haha but pretty costly

    I ordered the 2.2kW version of this VFD. I am happy to see it has landed in Richmond today. I should see it in a few weeks. Let the fun and games begin!

    Parker,

    I have a suggestion from an idea I saw on FB. Why not enclose the top part of your stand (from the crossmembers up) with sheet metal and install the VFD inside there? You'd need a fan and an air filter, but that looks like a super way to keep the dust out. You can wire your remote start/stop and speed control for easy access up top.
