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.

Are Caffrey's platen plans free?
 
I tested the EERF grinder today, it works better than I expected it too. I am very pleased with its performance. I will release the DXF files this weekend for those who would like to get quotes from there preferred vendor.
Let the builds begin.

Probably posting it on my website, will post link here for the DXF cad files when they are uploaded. I will have these posted in the next day or so.

I had a chance to test this grinder made by Blindhog today, and it was quite impressive. It is a little more complex in it's construction than I would have hoped, but I think the overall result was well worth the effort. I cannot wait fo r the plans so that I may try my hand at making this grinder.
 
OK did a test run today on the new grinder, It worked better than I had hoped it would. Tracking was very solid and very dependable and reliable. While its no KMG, its not far off either IMO. These photos do not reflect a few changes I made recently. This grinder does not have the new larger baseplate that will be incorporated in the plans and cad files.

One of the only things I believe I might need to do is raise part 2 to allow the toolbar to not be as extended. This is a 24 inch toolbar in the grinder.
What do you guys think. Am I missing anything before I release the cad files.

Cad photo is what the new baseplate looks like, but not on this grinder.

It looks great ! Will this be able to accept the standard KMG attachments and accessories ?

Great work on this and many thanks for all your hard work !

I agree, in the video i see that the toolbar seems to be extended out quite a bit.
This creates a lot of leverage and imbalance and makes the small baseplate more unstable.

While you are at it, I would also consider making the tooling arm receiver channel longer-both back and forwards.
(parts 3 and 4?)

You may also consider moving the tracking wheel further along the arm towards the front of the arm
(greater leverage/movement)

raising or making part 2 might be a good idea! in the video you can really see how its out of balance with that much of the tooling arm sticking out.

its pretty tho :)

Well heading to the workshop to measure my Bader and this afternoon recading part 2 to make it taller. Easy enough fix, the blueprints earlier in this thread will be changed accordingly. Will post cad drawing this PM.
I also need to figure out how to host the cad files on my website, wish me luck.

12345678910 The part 3&4 are the same length as on my bader B3, so I think its ok. I like the idea of moving the tracking wheel further forward though, effectively raises the tracking wheel also.

Looks good Chris.

I hope I will have time to build one in the future.

I was thinking about using this grinder for smaller contact wheels (3" and 4 1/2") Might have to use a larger drive and tracking wheel to keep the tooling arm from extending out to far.

Thanks for all the work you have done.

Take care

You could also widen #1 to move the motor back a bit, but try the length with a flat platen first to see how much tooling arm shortening you can get away with.

Just wanted to say you did a nice job and great gesture.

Take care, Craig
 
Hey Chris,

Could you lengthen part 5 out from the pivot bolt towards the tracking say about 2"? This would move the tracking wheel up and still leave access to the tracking knob behind the belt changing handle.

Thanks for the great job you've done on this project :thumbup:
