I Want A New Grinder

Corey - that's looking good. Don't worry about the welding - looks like it will hold nicely. Wouldn't be very hard to make that flip to horizontal position. I didn't think horizontal would be worthwhile..... until I did it. Now I use in horizontal fairly often.

I'm glad I was able to help,

Great work man, that's turning out nicely! :thumbup: It's so cool that the knifemaking community for the most part is full of guys so willing to share, help and even give, isn't it? :)

I would suggest that once ya get that running (or preferably before), to wrap a few layers of electrical tape around the middle of the tracking wheel so that it gives it a slight "crown". On mine, I also wrapped a thinly stripped piece of packing tape a couple times on top of the electrical to give it a been more of a "central peak" and also so it was a more smooth, or gradual "radius" transition for the belt to ride over. The tracking was like night and day after I added added the tape to my wheel. So just in case ya start it up and the belt happenes to fly off, you'll know where to look first ;) . Also, even if ya spin the belt by hand with the grinder off and it seems to track well, it might be different at higher speeds in my experience (with my grinder "NWG") so make sure ta stand to the side (obviously the motor side) when starting it up, which happens to be good practice in general for each time ya start it up.

I hope you make a vid showin it running when ya get it all finished up!

(Also, didn't anybody happen to read my post where I clearly stated that a 5/16" bolt was the size to use for going through the skate bearings?! :grumpy: :D lol jkjk!)

Thanks for the tip. The drive wheel I have is already crowned but, I guess it wouldn't hurt to add some tape. And yes, I plan on making a vid!

Nice work. I'll bet the wait to get it running is pretty intense!

Absolutely! As much info as Ken H gave me on wiring the motor and vfd, I'm still going to wait until my brother can help me a bit on Monday. Wiring freaks me out so I want to do it right the first time.
 
Awwww, electrical wiring (edit) "not" hard..... 1 wire hook up, 2 wire screw up..... 3 wire.... BLOW UP!!! {g}

I have a normal drive wheel with a crown on it as well, but since the tracking wheel is the wheel that gets tilted left and right to well, track the belt, it really helps to have a crown on it as well to help the belt slighty 'curve' and conform over it to ease the transition instead of a harsh flat surface with 90 degree angles which will end up making the belt 'twist' a bit and then completely run off one of the sides of the wheel. I think it's also the less surface area that the belt rides when it's crowned that aids in the tracking. You can always try to use it without the tape, but I'm pretty sure you end up puttin some on after you do ;)

Man I know the pain of waiting on just the wiring. I just had the motor to wire and I was stumped, let alone a vfd. Since I'd never done it before and had soo many questions, I ended up paying like $10 on one of those "ask an expert now" sites lol. It really did help though, cause you can ask as many annoying and stupid questions as you need to until your problem is solved, or your money back! :D I didn't wanna bug the guys here too much with my electrical ignorance so it was worth it ;) Hope ya get it all figured out soon so you can play :)

took the words right out of my mouth. I cant afford to fry a motor or vfd. lol. If I do, my grinder will be sitting there for a few months unused.
 
Just don't let any of the magic smoke out and you'll be ok. ;)

Really though, the wiring is the easier part. It's setting all the parameters that can sometimes be confusing, but fortunately, you USUALLY only have to do that once.

The nice thing about new equipment is that it's normally labeled pretty well, and the labels are easy to read.
 
Paul, if it was just a motor you should have hollered - there are several folks on here with LOTS of electrical knowledge 'n experience who would have been more than happy to help. Just wiring a motor is actually pretty easy, once you understand labeling on the wires. What's trouble is when there are 12 wires hanging out of a 3 ph motor with no tags on the wires. Now, THAT can be interesting. Not only do you have to "ring out" the wires to determine which are matched coils, but also figure the polarity of the coils.

Ken H. You are a life saver! Couldn't have done this without you. Tmrw should be wiring up the potentiometer and other switches, then its good to go! Video to come soon!
