FYI, for the 14-3 and 14-4 SJOOW (up to 300v) or SOOW (up to 600v) wire, if you are looking for a cable gland for the KBAC-24D, look for a PG-16 Cable Gland / Strain Relief. The PG-16 fits the hole for the gland perfectly in the KBAC-24D and also is perfect for the 14-4 and 14-3 wire.
I bought everything on Amazon for this grinder. KBAC 24d is easily searchable. The wheels and certain tooling was sourced from a knife supply company called Oregon Blade Makers.
Good vid. I just picked up a used KB 24d. Did u say that if u had an 1800rpm motor that the speed can be doubled? If so, do u know if this means the rotational speed of an 1800rpm would spin at 3600rpm and could this occur without torque loss?
The short answer on speed is yes but if the motor is rated for 1800 max rotational and you push it expect failure sooner than expected. As for as torque it likely depends on the motor style but in my experience any gain in speed is going to be a reduction somewhere else and vice versa. There is a gentleman named Jeremy Fielding who’s knowledgeable in these areas that you should ask about torque value...guy is a variable genius - pun intended.
Hey chuck, I have a question. After running this setup for a while what are your thoughts on 1800 rpm vs 3600 rpm motor? I'm sure you debated as well when deciding. I'm at the point of selecting a new motor with the same vfd. Any thoughts on this? pros? cons? Thanks in advance, Shawn..
There’s no debate in my mind that if you’re going to run high speeds required for clean grinding you get the motor rated for the higher RPM. You can get them around $150-300 at Amazon and mine is still going strong after all this time!!!
Thanks. I was thinking 2 hp, 3600 rpm with VFD. Wired for 240V. I don't have any experience with VFD's. I imagine I will be able to turn it down enough for slower material removal (scale work and so on) but still have enough bottom end. Unfortunately not much info online, just a lot of recommendations toward the 1800 rpm...
If I had to again I would buy a 2HP at 3600. You can reduce the speed to almost nil so I’m not worried about the low end but I have been able to stop the belt if I really push hard which you could get away from with a 2 HP. I did 110v because it’s more accessible and I only have my welder on 220v.
chuck thanks for the video i have a question i just purchased a 2x72 with a 2hp motor and vfd when i put it on fastest setting didnt really go very fast so after wathing this video i put the jumper into the 2x slot now it goes very fast is that ok for my grinder im asumming it should be ok just dont want to damage it thanks mark
@@Anderson-HandForged Does your KBAC 24-D run a 1.5hp three phase motor? Have you experienced any problems with this setup? I was told the 24-D will only run a 1hp motor.
morty I’m also so confused how he got them in the hole... I bought the same ones and the wires wouldn’t fit inside... actually the 12-4 fit into the 3/4 strain relief it was the 12-3 in the 1/2 that was the problem...i searched for different ones everywhere... I think the insulation on the 12-3 I bought is way thicker. I finally gave up and shaved some of the rubber off to get it to fit into the hole to finally wire up my kbac-27 on my disc grinder.
morty I put all of my tools on a 30 AMP breaker that pull heavy loads of power because they are rated as such. For instance drill press, wheel grinder belt grinder and air compressor are on a 30 amp breaker. You can run on a 20 amp no problem but they may pop the breaker more often. It’s just what the cabling is rated for and no other reason.
@@Craft518 I got it hooked up but the wire i ended up using didnt fit in the connectors very well i just wrapped a little electrical tape around the wire so it was a tight fit. Besides not being able to find that wire the video was very helpful thanks man!
Nick Riggi it has been for all my needs. I’ve made knives, shaped handles, ground metal for other projects...you name it. It would be nice to have more but I really have to press hard to get it to stop. At that point you should be using and angle grinder and saving precious belt abrasive. Good luck
Not Two Phase, Single Phase. The typical house wiring is Single Phase, which will then power the KBAC-24D VDF, which then converts the Single Phase input to Three Phase output and runs the Three Phase motor.

See what you just did there is went full NASA on us. I went more, "fit square peg in round hole' with my attempt. Really appreciate the detail!
@@Craft518 Your instructions were very good.
Good vid! Definitely gonna watch again when I wire my 24d!
Happy to help
Thanks so much. Video helped a ton getting me up and running!

You said you got the mc-60 treadmill motor controller on Ebay. You wouldn't happen to have a link or listing info for that setup, would you?
www.ebay.com/itm/303159304376
This was my first controller. Blown as explained but could be easily fixed.
I like your setup, would you please share detail information of your motor, and drive? Where can you buy them?

What kind of motor and VFD do you have?

Where the hell did you find that wire that fits perfectly into the connectors iv been to every hardware store lowes didnt have anything close to that

Why do you have it plugged into a 30amp breaker is that neccessary or will it be ok on a 20amp by itself??

The way you wired it runs off of 2 phase correct
Caulin Oden 3 phase wiring and diagrams were used
@@Craft518 it plugs into a normal house outlet correct
Caulin Oden yes depending on where you live the voltage will be different but it is USA 110volts

what size drive wheel do you use ?
Mike Horsley 5 ½ plastic.
