The plans show a couple really thin pieces. What thickness are these?

WHat you see above is the GIB set sold by polarbearforge.com. You will not find plans for it on the internet, it is a slight variation of my EERF grinder.The main difference is it has two tooling slots vs one tooling arm slot on the EERF.
So if you decide to cut my free plans on my website you will not get the above pictured parts.

You are certainly correct. Still, my problem/confusion remains. Yours are the plans I sent to the fab shop for a quote. They asked how many of each and I sent them the wrong pic. Still, in yours there are two piece on the top left that I don't know the thickness of. Thanks for the plans! They are awesome.

1/16 inch on the thin parts, is how I made mine. But you could even go alittle thinner if you like.
PS anything between 20 and 16 gauge would work fine also.
Chris
PS If you think this is a nice grinder wait till you see the next one I am working on.
 
Well don't have me build this one, shoot me the plans and I'll have them cut the new one, hehe. 1/16" it is. Thanks.

Seriously, I'd gladly take the new design and build it since I haven't really started yet.

Sorry but the other grinder I am working on is not a bolt together unit, Unfortunately it takes many machined parts. ANd not near as fun to put together as the one you are going to do. Stay the course you will not be sorry.

The shims that I include with my kit are 16g. Some haven't even used them. Evidently some places have 1 1/2 inch square stock that isn't quite 1 1/2 inches nor square.

Nice looking grinder Chris. I've seen it around the web a bit.

Very cool looking grinder you got there.
I am in the midst of building one with a double tooling arm holder, that's got a lot of similarities to that one.
Hopefully the waterjet is done tomorrow...

If you can not get my grinder plans cut for $250.00 or better make sure you check out Jamies kit at polarbearforge. It really is a good deal. Heck I even bought one from him when the quote I got for cutting my kit in steel locally was $300.00, Plus Jamie improved my design slightly(double arm grinder), includes a platten and also asked for my permission to sell the kits.
Jamie That dang grinder build got me hooked on designing grinders, this was the next logical step (Wilmont grinder).

Would love to see some photos of your new grinder, I think we can all learn from each others designs.

I'll start a thread next week.

Got the stuff from the waterjet guy today, but I'm heading to the Plaza Cutlery show for the weekend.

Should only take a day to build.
It needs very little machining..

I think these plans, and kit are outstanding.
I have that much invested in material and waterjet myself, with no tooling, just the chassis.
All my KMG stuff will be used on this one.
 
Just waiting to hear back from Cox-Design. Not sure if they are quoting waterjet or laser since they do both. Their first quote was only $75, but that was only for the multiple parts 3,4, and 8. They didn't quote everything.

Oh, I didn't realize Jamie's kit came with the platen attachment. I just need the square stock and a platen. That's cool. I will probably end up doing that.

You guys want to see my grinder conversion? It's a 4x36 from Menards with an 8" wheel attachment to make it into 2x72. Nowhere near the quality of yours, but it works. I used an 8" caster from Northern and replaced the bearings with sealed bearings. I had to manually balance the caster. I did this by removing the belt and letting the wheel stop moving. The heavy part of the wheel was at the bottom. I kept adding magnets to the top until the wheel was balanced. You can see the magnets in the caster top right, about 2 oz worth. Tracking is provided via the 8 4-40 screws around the top of the post. Two bolts and I can remove it from the grinder and use it at a 4x36 again.

Hey dont knock your work, I think that grinder is awesome. You took a grinder that probably would not have worked well for grinding knives and modified it with what you could find locally and made it work. I love home made tools and am always tinkering with a new jig, fixture or grinder tools. Only thing I might suggest is a toolrest. but then again I grind with one and you might not so take that bit of advice only if you need one.

Guess what I bought today, a 6x48 belt sander, its old school and one of the rollers can be adjusted about 6 inches with a handwheel. WHen I saw it at a tool dealer I instantly said slow speed grinder.
For those not knowing what I am talking about check out Brians slow speed grinder on his website.

Chris, send it back and make a platen for a 2x72. It is FAR superior to the 6x48. I recently sold that one to the guy I got the idea from ...

I'll post pics of mine when I get the new grinder up this week. I think there might be some here already, I know I posted them somewhere.
 
Brian
Thanks for letting me know before I put a bunch of work in this 6x48. Cool now I have a 6x48 I can use for other projects (Woodworking etc). Would love to see the photos of your platen for the plunges on your 2x72 if you still have them. Although I can imagine how I would build one, I might start working on that in the next week or so.
Thanks for the idea.
Chris
 
Chris, thanks for the encouragement. Believe me, I've thought of designs for a toolrest. A lot of my grinding has been slack belt between the bottom of the platen and the drive wheel. It's about 3" and just the right tension for a slight convex.

I had to modify the plans, I put the platen on the other side between the contact roller and the drive/power roller. I learned that dust collection is much better is the sparks fly downward instead of up. The platen is made of some aluminum stock from, of all things, a marching band drum set. Just the two bolts holding it in place and it hasn't moved a fraction since I installed it. I'm currently looking at how I can change the speed with a different pulley. It's a little fast but works. It'll make a great grinder at home when I build the grinder in a box.
 
If you are only going to build 1 grinder I would wait for Chris's new design. I have one (1st design) and it is an awesome grinder. It is a workhorse of a grinder. I am also building Chris's old style grinder (eerf) just because I enjoy building things and I have a Thursday night knife night and I am short of grinders.
