FINALLY, after 3 months of saving for all of the hardware, I got the last screws in the VFD box! Took me about a full day of tweaking and modding but it tracks nice, all the way up to 5700 FPM! My welds are embarrassing to say the least!

VFD box with Busse Combat pic to cover the wiring, external control for start/stop, speed, and reverse. In hindsight I should ave listened and got a 3 turn pot cause the 1 turn is extremely sensitive! I know this box is good, it's filtered my FRAM!!!!

Pic of embarrassing welds - oh yea there's a grinder in the pic. When I turned the wheels I gave the edges a lip for added insurance from belt throwing while operating at warp speed! The belt does track nicely though.

Other side. This pic kinda sucks a little. Hey, it's not like I have my lightbox out there, and it's cloudy and rainy this morning. More sucky welds.

At least you have a grinder! Great job. I like the "PC" box for the VFD.
 
Who cares what the welds look like as long as they do their job. Give it a nice paint job and they won't stand out so much. Although, welds are like tattoos, after a few months you'll forget that they are there unless they are pointed out by someone.
 
Oh, and BTW, nice grinder.

You might find that canting the platen back a few degrees might let you see what your doing a little better, and make grinding more comfortable.
 
Thanks for sharing with us - I am still "dreaming" about doing one - you are using yours.

You can't quite see it, but I milled the rear mounting hole for the wheel/platen mount so it can tilt.

I'm jealous, I really want a 'real' grinder. Was this a NWG, your own design, or ???

I had no plans, but I cannot exactly call it my own cause it looks too much like another grinder we all know too well!;) I looked at a lot of different homemade grinders on the MSN groups pages, and also production grinders and that is what I came up with.

You would not believe how quiet this thing is until you crank it. It can be more relaxing while finishing a blade. Less noise, more concentration on what you are doing. Also makes it easier to listen to Cannibal Corpse. That really gets me in the groove when I am finishing a blade.:thumbup:
 
The VFD was 140,
motor 120,
64.56 for the drive wheel (sunray 6x2.50)
50 for the steel,
10 for bolts,
15 for the alum stock for wheels,
bearings were 20 for a dozen,
4 for the door stoppers for feet,
3 for springs,
14 for air filters,
20 for 10-3 and 10-4 hook up wire.
20 for switches, transformers, fans, pot, rectifiers.
The 7x12 lathe was 400 but I do not really include that cause I needed the lathe for something else also.

Start saving up, that's what I did. Buy a little here, there.
 
AWESOME WILL!! I am a firm believer in using 3/32 6011 rods @ 225A! Spatter?? WHAT spatter?!
 
When i was a kid i was asked if i wanted the welders job as he was retireing i refused and regreted it ever since. I love welding and would lay in hot slag or what ever never bugged me alot burns heal i always said . So as time went on i offered to weld anytime it needed to be done .Some of the guys i worked with that hold their ticket would show me lots of tricks. It does take practice but youll never forget.Just like 2 weeks ago i welded a tang on a knife put the knife in the vise and free hand held the tang lmao 1/16 rod and buzzed it on like perfect.After i ground it off on the 2 i welded i could not risk another buzz and left one small spot the size of a flea. The old man says to me you left a spot and i replied can you do better he said nope. The moral of the story is if the globs hold who gives a f__k nice grinder . kellyw
 
I am going to mod the tool arm by moving the wheel/platen mount back about two inches and use the overhang to mount the work rest. I am going to countersink the mount bolts in 3/8 alum for the rest. I think I have used enough 1/4 mild plate. The plan is to have a tool arm for slack belt, another for the platen, and another for small wheel. For right now I am going to mount the platen to this one and make the platen removeable. Tomorrow I am going to throw together a short span slack attachment. Right now I have 12" of slack, a little too much for what I am doing this week. I am gonna try 6".
 
Nice work.

I'm considering building something like that for myself.

How many horse is that motor?
