My KMG is three speeds, My bader is only one speed.
I like the fact the KMG is bolted together making it modular enough to tweak, drill and modify to my tastes. My bader is a casting and while it is a very good grinder I do not consider it in the same class as my KMG.
Having said that if you are using a 1 x 30 sander then a EERf grinder is lightyears ahead of what you are currently using.
Lets talk about the three different ways you can get 1/2 aluminum or steel cut.
Waterjet cutting= The slowest therefore probably the most expensive. A waterjet cutter cuts half inch steel twice as slow as aluminum therefore even though steel is cheaper as a material it will cost you more to have it cut vs aluminum.
Laser= very fast, meaning cheaper to have cut than a waterjet cutter, clean cuts, very precise and the best way to go in my opinion. But very expensive so your local steelshop might not have a laser or might not have one that will cut 1/2 steel.
Plasma cutting= all cut edges will need to probably cleaned up with a side grinder or sander. Will probably be the least accurate of the three and the one that must be cleaned up the most. IE holes drilled out w drill to clean out hole and sides sanded to clean off slag. But probably the cheapest to have cut of the three options. This is the one your local shop will most probably have that can cut 1/2 steel.
Hope this helps you guys choose which vendor to have your parts cut by.

I guess I was asking more about the difference between the EERF and the KMG. If you had an EERF grinder and a KMG outfitted the same, same wheels, same motor, vfd, tooling etc., what is it about the KMG that would make it better?
I would think the EERF is modular enough to tweak, drill and modify to anyone's tastes.
I am just trying to figure out what the KMG could do that the EERF could not. Really what it comes down to is that if I have to spend $800 on a complete EERf and $1200 on a complete KMG (just making up $$ numbers)...is it worth the difference?
Or would I be able to do more by building one of these, investing the saved money into additional tools...etc. etc.

Greetings all! I had a chance to work on it tonight, and have to make a few changes. If my material comes in early enough tomorrow, I'll cut new pieces, otherwise I'll cut them at the beginning of next week. I don't want to start production until I'm positive that everything plays nice. I'll also draw up a few platen designs to get some input by this weekend. Thanks!

Phil,
not to get off topic or flame anyone but i called Dave back in September or so and placed an order and never got any response after that to any emails or phone calls and no blanks of course so for myself unfortunatly he just isnt an option.

just got a quote for laser cut $340.00 + shipping. To cut two out it was just $41.82 more. If you had two guys interested on going togather it would be $191.23 each plus shipping. I still have more quotes to come in. I will let you know how much thay are.
I was just thinking the same thingt a group buy. THis kind of thing just begs for that. I bet once the design gets stabilized, we could get a group buy that brings the price down significantly.
For hose of you who already got quotes, did the quote also include the steel or do you have to supply the steel?

I think steel would be better and a CNC plasma cutter would be way cheaper. Of course you would need to clean up the edges with a grinder. I dont think it needs to be 1/2" thick steel, maybe it does if its aluminum but not steel.

Ok, I had a chance to look at the multi platen and draw one up. Here's the kit as I currently have it.
The top 3 pieces are shims, and will be cut from 16 guage steel (or so) to space out the sides so the tooling bar and workrest bar will fit.
The rest of the pieces are from 1/2 inch. The kit will include 1 of the 2 pieces shown on the right hand side. One is a standard platen, designed for 2 or 3 inch diameter wheel use. The other one is based on the multi platen that I've seen. According to my drawings (I didn't have the wheels to test this yet) it should work with a 2 or 3 inch wheel at the top and a 4, 5, 6, or 8 inch wheel at the bottom. Both end up with about a 9 inch platen length.
Remember the plastic models you made as a kit? They had the parts all in one piece and you broke off the piece you needed? That's the concept behind the cluster at the top. It's easier for me to cut and keep track of. You can cut or break off the piece and then round the broken part smooth with a file.
The total cost will be $260.20, $250 for the kit and $10.20 shipping via priority mail.
I'll try to cut a verification kit early this week. I was planning on having some kits ready by the end of the week, but I just found out my father is in the hospital and not excpected to make it very long, so I may have to delay things a week or two.
