What is your dream KMG attachment?

Are you considering having the rest itself laser cut?

You could have several done from on sheet of material for a better cost than machining each plate.

Also, you might consider using square 1/4 wall tubing for the receiver to keep costs down. Shouldn't make any difference on strength or rigidity.

I'm a machinist in a large manufacturing facility, so if you have any questions, please let me know. I like your design, and I think you could do well with this.
 
I havent been able to find tubing that will accept 1 1/2" square bar. I dont think there's a common size made that will accept it. I also have no problem lasering the work rest. At my last job I was the Engineering Director of a large matal fab shop. I had 2 lasers and tons of scrap structural and plate at my disposal.

Now Im a project engineer at Yaskawa Electric and I have tons of VFD's at my disposal. :D I saw them scrap a crate of them shortly after I started. There was nothing wrong with them, They were last years models that were used in the lab. I should have grabed them but I just started and I didnt even ask.
 
I love the design, and hope you can see a return on your investment. If you do not start selling them - will you make the drawings available for us? I am new here, but from what I have read a large majority of us are willing and capable of building our own. I for one am willing to pay for your effort and development costs and then eat hot chips in front of a Bridgeport for a few hours to have a toolrest like yours.
 
I got 1 quote back and they must be mad at me for some reason.
1 pc of 1/2 x 3/8 bar, 2 1/2" long with 2 holes drilled in it is $37!!

Im still waiting for the other one. Ill keep you posted. Thanks again

can u post a close-up of how the plate is attached to the round ?
The underside of the plate. Unless it is a patented joint, of course.

I am wondering how you rotate the plate in horiz plane, to present
different cut-out shapes to the belt and also how it rotates in
vertical plane (if it does)
 
I got one quote back and it insane how much it came in at. My cost for just the parts, with no hardware and completly unassembled is just under nine hundred. :eek:

Needless to say I am waiting for a few other quotes. I am also thinking about what im going to do with that 3rd arm (i think I have a very creative way to make it "available" to someone) Im also considering making plans available for anyone who is interested if the cost comes in to high to sell the completed arm.

A few more days and I will let everyone know. Thanks for your patience.

O.k..... I'd be interested in that "creative way to make make the 3rd arm available".... also interested in the plans if its too high... Thanks for all your work on this....

I've been following this thread as it developed and I admit that I was, really, really, really afraid of where this was going to wind up. Small runs aren't worth the time to set-up a CNC machine and labor cost SOARS (people have to eat and business' bills have to paid and we wonder why all this work is moving overseas?). I recently got quotes on a short run (<100) of knifermaker's/cutler's steadies (or as the Brits say stiddies). The best I got was a per piece price of over $200, which stunned me, considering materials cost of under $25. Go figure.

My simplistic idea is that it might be, while potentially less profitable for you, more workable in the long run, to sell sets of plans which can be provided as a booklet produced at Kinko's, a DVD,or a downloadable PDF or MS Word document. I would buy a set of those for sure, if only to support the cause. Probably not what you wanted to here and feel free to tell me to buzz off.

Thanks for sharing this significant advancement in grinding accessories.

Its starting to look up! I got another quote back and the price is 50% less than the first quote. Its still to much I think, That would mean I would have to sell the arms for almost $600. Thats if I buy 20 at a time. I was hoping to be closer to $450. What do you guys think. Should I just make the plans available or try and get some cheaper prices and sell the arms?

Wow. I'm so damn newb, and haven't even gotten my KMG, so I can't even envision how useful that would be....

Looks phenomenal though!!!
 
I'd try to get some cheaper prices first. If you could get it around $500 that would be good to me. Otherwise, you could make the plans available. But, it would probably end up costing most people more to have only one made for themselves using the plans.

At $600 I'm out. Even at $450 I'd be iffy. At those prices I'd probably buy an edge finishing grinder from Beaumont instead ($650).
 
450-500 not out fro me i just have to plan for it
plans dont much help me caue i never seem to get projects like that done
 
maybe have both? because a lot of guys would much rather just buy the thing than have to spend the time making it, but then there's also people like me who don't have much money, but have lots of time on our hands...
 
I just want to make sure I was clear in my post. I am NOT offering these for sale at $600 or at any other price. The quotes i got for most of the parts came in alot higher than I expected. I am still working to get the cost down and if I can offer them at a later date, I will. Right now im just getting information. Thanks for all the feedback, Im listening.
