I decided to get in to knife making and after looking at all the options I decided it would be fun (and cheaper) to make my own.

I didn't think about pics until I was almost done so I'm sorry but no "in progress" photos.

Those are the main parts before paint, here's the finished grinder...

I got the plans online from Jer's Woodshop, he also has a You Tube channel where you can see him build it. The plans are only $20 if you're interested.

2 hp Baldor motor. 240 volt, 3 phase, 1800 rpm. I have it hooked up to a Hitachi VFD which I can vary from 0-120 hz.. The wheel I have on the motor gives me approx. a 1-1 ratio so I can run it from 0-3600 rpm.
I used a thick piece of steel on a 36 grit belt and tried with all my might to stall it out and I couldn't so I'm real happy about that.

I follow a group on FB (Home Built Belt Sanders) and dream of a day when I have time to make one, or get motivated. ;) Yours look nice and heavy. I have a 2hp Baldor from a large furnace fan but I think it is a 3600rpm. If you don't mind me asking, how much was the VFD?

I have been looking at different belts sizes and lengths to make one and choosing what size I wanted. I really would like to make one with 4 inch belts but can't find long belts in 4" size. I finally figured that it would have to be the 2 x 72.

THEN I SAW YOURS! WOW. Love the different iterations and configurations that yours morphs into! Versatile! Love it! Excellent!

I have the metal square tubing to build one, but now I have to go and re-configure how I will build it! I probably won't build it to go from horizontal to vertical but the other vertical configurations I can do. Thanks for posting this!

The VFD was about $300 and the remote faceplate was about $100. You can get cheaper VFDs but I bought that one because it's the same one I have on my metal lathe and I already know how to set it up.

Very nice one of my eventually build plans.

Does the plane tell you where to order the rollers from?
He doesn't say in the plans but here's a link to a first rate set...

You can get cheaper but you know what they say!:)

One more question for the bonus round Rick.
You said you wanted to make knives. Are you doing metal removal knives or are you getting your "Forged in Fire" :rolleyes: on and hammering them out of hot metal?

Stock removal only. I couldn't do forging even if I wanted to, I'm disabled from a work accident 15 years ago. I need crutches to walk and stand so swinging a hammer is a bit much. :)
