New grinder plans for download

New changes look good, I posted them
on my website.
Man this GIB/EERF grinder just keeps getting better.
I like that you included a photo and two different dxf files depending on if you want to tap or not.

I was quoted 50 for the steel and 100 for the cutting. I'd realy like to try that multi platen (the tear drop lookin one) on PolarBear's site. that thing looks like it's the poop:thumbup:
 
I didn't see much need for the second platen design. I thought about incorporating it, but you could have two identical platens and just put the different size wheels on the second. With the rounded off back of the Smiley Platen© the extra material doesn't get in the way like it did with the squared off platen.

For $150, I'd say go for it!
 
would a guy be able to run a 10" wheel on the smiley platen? I have a 10" wheel now and would like to be able to run that as well.

Cutting edge
If you can get this cut for $150 then you got a great deal. I tried to get my files cut locally and it would have cost me $300 which is why I just purchased the GIB for my workshop.
Polarbearforge is doing us all a great service by ensuring we dont pay too much locally for this grinder design.

PS Edited to add Polarbear forge charges $250.00 for this grinder (Good deal IMO).
 
I'm getting a family deal. my brother in law(sister's hubby) is shop foreman at the machine shop and is charging me cost on the steel. we'll go in and cut it on the waterjet on a saturday when the shop is closed for buisness. he has to charge me 100 for the Garnet. we'll be cutting it after the holidays when I have some money again lol. gonna have my father in law weld it together for me

Click to expand...

At that rate, get 2 cut at the same time.

I'm not kidding.
 
Hey Zaph1, Do you mind if I add this to my thread on DIY tools? As well as the rest of you that posted the PDF and JPEG files for further convenience? Thats a Pretty clean set up Zaph1, Thanks a lot for sharing it with us. I'm sure this thread will be followed for a long time. I may try to get a quote on this cutout myself at a local shop. I may mod it a little, Only wish I payed attention a little in CAD class back in High School... The 2011 layout is so different, from the old skool 2000 version I used anyway.
 
Why would I mind. Sharing is what the EERF grinder project is about. FWIW: I did almost everything in CadStd. It's a free CAD program. Not the best, but it did the job. You can download the free version from their website, www.cadstd.com
 
So I've decided to have my wheels made for me instead of buying them. I can get them made free from alum. Scrap they have laying around at the shop. Just need to know what size should the hole for the shafts be?
 
Most use 1/2 bolts to secure there Tracking wheel to the grinder.
BUT you are going to use bearings right??????????????
If so then you need to look at the specs of the bearings you choose to decide the holes diameter and depth.

Most of the plans are for 1/2" axle. The drive wheel would depend on your motor shaft. It's sad that the wheels are more expensive than anything else on the grinder.

A common size of bearings, 1/2" x 1 1/8" x 5/16". Cut your 2" wide wheel, 1.125" / 1" counter bore 5/16" deep. The bearings should fit through snugly into the ends of the wheels.

I hate to be a pain in the rump, but I'm quite mechanicaly challenged. I was wondering, I work for a company that manufactures garage doors and all the hardware used to install the doors. I have access to 1" ID bearings and also 1" shafts (solid or 14ga tube) if I was to make my wheels to use those bearings and use the 1" shaft or tube that'd work right? the drive wheel I'll make to fit the size of the shaft coming off the motor cuz it wont need bearings. sorry if thats a dumb question :o
