    Holy crap man that's not good. So much for buying local lol.
    1500.00 I think the grinder comes with it hahahaha.
    KBAC 29 is the same ones I have . I bough two with safety switches and forward and reverse switch wired in by them and with the tax and exchange rate plus shipping I had them to my door for 950.00 for both if my member services me right.

    Sent a email off to the American supplier will see if they want money. Mind you a good finish to this week I was going to swap out pulleys to increase belt speed, wheel does not want to come off and I hid my puller a little to well.

    Lesson to be learned "Don't put things away" or at least make a map of where you hide stuff. :roflmao

    I know that feeling problem with me I can never find the map. Lol Most times these days I just write it on the shop wall.
    Walker industrial was the best place I could find .
    One other thing I had them do for me was double the speed into the drive. Then with a 5" direct drive wheel I have and the speed I need.
    I wish you luck

    KBElectronics gave me dealer info for BDI Canada and price is down to $720 each.

    Price from Walker in the States is $378 and converts to $495.41 Cdn add in shipping, brokers, tax and stuff I guess it will be close.

    Well I am amazed finally got the speed controller biggest surprise was the distributor in Winnipeg could not figure out have too get it to me by mail or courier. Apparently not set up for that kind of thing.

    Used a 6" drive wheel and a 1740 rpm 3 phase motor and belt speed is 1000 SFPM faster then the original setup. Tested out on a 1/4" thick meat cleaver I keep putting off and I am smiles from ear to ear and only dread the first time I feed it a finger at full speed:eek:

    Boy that board looks like sousaphone oh well another project. One thing I found in a very short run is that free hand grinding might be easier at full speed and I can run it very slow for heat treated blades as well as wood and plastic.

    Old motor is likely to end up on another grinder so I can get a 10 or 12" wheel for hollow grinds.

    So far burnt my fingers four times , have to get used to half as many passes before cooling.

    Really liking the higher grind speed and doing a small blade in less than half time

    Yes, faster is hotter. A fresh belt helps reduce heat significantly too. ;)

    The odd thing is the speed I can work around but the brain locking onto the fact the grinder is different and the knives were started on the original setup and should be finished before starting on the new grinder arrangement. Took two days to struggle with that and get some grinding done, still not finished them but they are coming along nicely.

    Been way more fun than it should be and free hand grinding is actually easier and the blade finish is much better with the higher speeds. I can see a major improvement when it comes to mirror polish time on a couple of these.

    Every blank I have had cut out and sitting around is now shaped and taking them all up to 400 grit before heat treating. That Karambit type thing I have been waiting for ten months to start it, kept putting it off until I felt I could do it justice with free hand grinding.
    Still like to do a couple passes in the holder for really fine tuning the lines of the bevel but free hand is much faster once you get into the swing of things.

    Your doing good with all that speed. It sure do help to remove steel fast. Did you change your wiring in your drive to double the speed.
