2" x 72" Belt Grinder kit $369.99

First off, thank you all. Wil got me for 600 plus, but I still want a grinder. I downloaded the blueprints and dxf files and will forward those to a company for pricing. I have autocad here at work but do not know how to draw with it, just use it to clean up dwg files and plot out drawings. There are no dimensions on the dxf files, so I'll assume everything is drawn to the correct scale for the waterjet company?

I liked Wils design of the rotary platen. If I get this up and running, I may try to design that platen with an 8", 2" contact wheels and an adjustable platen. Seems like that would offer alot of versatility to flat grind, hollow grind, contour and slack belt gring all without removing the tooling arm.

Any chance of getting all of the bolt specs and quantities as well as the handle and adjustment lever specs. I have not built or do I have a grinder to work off of to see how the idle and contact wheels are attached and with what type of fastener that allows them to spin freely.

Than you again.
 
I envisioned this a DIY grinder, IE you get somebody/anybody to cut the parts out. You then drill/tap the parts so you can bolt it together. And paycheck to paycheck you get a motor, drive wheels, tracking wheels, bolts, nuts etc until you have a grinder.
I plan to have more info on my website on how to assemble, and Jamie at Polarbear forge has had made some really good improvements which I will incorporate into my plans. I think as more people build this grinder it can continue to be improved, I built the one on my sight for my workplace. Now I am going to cut one for myself soon as I think I am going to like it better than my Bader. I have been using it at work everyday and its pretty impressive.

Correct, the scale is 1:1.

I was planning on making a piece to include with the kit for a regular platen setup. I can work on it a bit and make it similar to the adjustable platen like in the original. Ed Caffrey also has a design that is similar, no?

I have alink at home that has a good picture of wheel construction. Otherwise ordering them from Beaumont Metal Works would probably just as easy. I will try to assemble the most recent batch of revisions this weekend, and I'll take pictures as I go a long this time.

It's a great concept and a great way to do it. After getting the kit parts cut, you pretty much need wheels and a motor. Pricing out a few wheels and motors online, you could end up with a finished grinder for around $625 ($250 for the kit, $58 for tensioner, $53 for drive wheel, $127 for a 6" contact wheel, ~$140 for 1 hp motor plus misc parts).

Ed's platen design has the largest contact wheel of 3". An 8" wheel on this design would appear to be more versatile.
I already have a VFD and 2hp 3ph motor. But you are both correct, I can start pieceing this together and make additions and or modifications as I go and not have to spend money all at once.
If there are going to be further design changes or the addition of a rotary platen similar to Wils original, I'll wait!
Thank you again

mo-jard,

You just download the files and either cut out or have the parts cut for you at a local waterjet/laser co. After that, add you motor and wheels (wheels can be purchased from USAknifemaker or Beaumont Metalworks).

Jarod (JTKnives) built a rotary platen and posted designs somewhere.
 
I won't have time until this weekend to work on this. I'll assemble the final revision and post picture of the process and the final product. I'll also post a picture of exactly what is included.

Until I have units boxed and ready for shipment, I am not accepting any payments. When I'm ready, I accept credit cards, and that will probably be easiest the whole way around. I am compiling a list of people interested, so if you'd like to be on that list, just let me know.

I would (Therron Shaw)
 
Just received a quote to have a local (Chicagoland area) waterjet guy do the cutout and it is about $260 for steel and $450 in aluminum.

You can add me to the list as well and thank you!
 
Thanks Nathan - I just knew Jamie was planning on doing it, saving me the time and effort to have it cut myself. I doubt I will find a better price on getting it cut myself.
 
I can say this is easily as nice as my Bader B3, but lets face it a KMG is not even in the same class as a Bader.
The KMG is the Cadillac of grinders.

ok Chris,

if you had one of these grinders and a KMG outfitted the same. same motor, vfd, tooling etc.
what is it about the KMG that makes it better or a cadillac grinder? all i have is a 1x30 so i'm really struggling to understand the difference.

sorry if it seems like a stupid question just really curious

thanks
