I like the legs Chris but my thinking was that having the motor mounted to the base and the frame would add a measure of rigidity to the grinder which may or may not be needed but couldn't hurt anything.
Thanks for doing this.

I completely agree with you in that it would make a very sturdy base. Far more sturdy IMO than my alternative. The only problem is that one will have to shim under the motor in order to bolt to base as not all face mount motors are the same diameter. I will post the plans tonight for the stock base and the extended one you suggest.

Nice job with the drawings. I'd imagine you have quite a few hours in this endeavor.
Your build pictures are enticing me to take the plunge.
You mentioned dxf files. Are these the files a CNC guy would upload for the cutting or is it an autocad format.
Thanks

If I sent your dxf file to my favorite waterjet cutter he could reduce everything by say...40% or would it be a pain?

DXF files are 2d files (Autocad format) that a waterjet operator or a laser operator would need to cut the 1/2 plate. These plans are designed to be cut from plate as the water/laser would do all the cutting and drilling of the holes. WHat you would pickup from your friendly waterjet/laser man is exactly what I showed in my first set of pics. Only thing one would have to do is drill the holes in the end part of the sheets or the 1/2 side. Laser/water can not get those holes.
No machining other than drilling/tapping a few holes is all that is necessary to bolt this grinder together.
Actually only a hour or two after dinner for a few nights is all that was needed to cad this. I apologize for the sloppy blueprints I will clean them up in the next night or so and repost.
Bruce just downsizing these parts will not get you a smaller grinder I fear, Because then the motor would not mount to the plate properly. I guess the question I would have to ask is what size toolbar would you want to use?? Resizing the parts that make up the toolbar is easy to do.
PSS If we all ask real nice maybe Great lakes waterjet will offer a DIY set. IE You do all the assembly/drilling/tapping etc.
Trust me guys I have built a KMG clone it took me 7- 9 months of a few hours a Saturday to get it finished. This grinder only took about 2 hours of time to assemble once you get it cut. THe DXF files I plan to post soon can be sent to any Laser outfit shop or waterjet shop in the States for a quote.
PSS I ordererd all the drivewheels and tracking wheels from Beaumont today so hopfully in a week or so I can post a video of how it operates.

Thanks Chris. My suggestion stemmed from my checking the six c-face motors that I have in my shop. three of them have different sized bodies but the distance from the centerline to the bottom of the base is the same. I have three bladors, one leason DC 1hp motor and 1 blador 1/2 hp motor. So I assumed, based on the examples that I have that all c-face mount motors with bases would be the same.

I would use a smaller motor and wont need any holes pre-drilled. I'm sure I would have to scratch my head on a couple parts to make my wheels fit too for a 1 x 42 belt size but still think I could do it.

I'd be curious to know what it would cost to have Great Lakes cut this out and or offer a kit.

I measured two or three of my face mount motors and thought I remembered they were different from the base to the center of the spindle. Although I measured early in the AM and could have gotten it wrong. I can tell you the face mount motor I currently have attached to this grinder is 4 inches from the base to the center of the spindle. If we can confirm all face mount motors are the same I can adjust the cad files to allow bolting of the motor to the base piece of aluminum.
Let me know what your motors are from the base to the centerline?

Latest mod, only compatible w 56 frame motors. Which means the pallet of three phase motors I bought at auction will not work, Dang it.

PS I updated the above drawings to reflect the new photo
PSS Beaumont metalworks is backlogged on the drive wheel I ordered so am just waiting on that to test my grinder.

Sunray inc www.sunray-inc.com is a good source for wheels at a fair price. I purchased contact wheels 8"x2" for $75.99, 3"x2" for $38.17, 1.5" for $46.97They are located in Rutherford N.C. I'm utilizing the 3" and the 1.5" on the caffrey platen that I recently built from Ed Caffreys plans. I was taken by Hurley back in October for a little over $700.00 for a complete grinder kit and contact wheels. I faxed a police report to the Scioto Sherrifs office. Det. Paul Blain said they would add it to the numerous complaints and charge Hurley with a felony count. I just bought a KMG, got the wheels from sunray and built the custum platen. Using a 2 hp Leeson single phase I found on e bay and KBAC 27 d varible speed drive from State elecric. Saved a few bucks getting the motor, speed drive and wheels from other sources. I'v followed this thread for a while and I'm glad to see these EERF plans become available.

Big plus one on that mate !:thumbup:
I can't wait for the dxf file! My father-in-law runs a shop with a waterjet so I might actually be able to get a grinder up and running for a reasonable price this way. One question though, are there any plans for wheels, or are they too complex to do easily?
