Well some of you might know by now that I'm building a KMG out of Stainless steel. i have wanted a Stainless steel grinder for awhile but did not have the means to do it. I have a NWG which is sweet and i will keep but i have wanted a KMG for a long time and with where i work i figured hell ya lets make one out of stainless. i will update this with pictures as the build goes along. i am working on it a bit each night. right now I'm milling the receiver plates. because of the price of stainless i cut all my parts out of odds and ends that i have collected over awhile from my surplus store. so all the peaces are not very even and need to be milled and will come out just perfect and within + or - .003 which should work great. pictures on the way.

I chose to mill all of my peices from plate... bad idea.
I still dont have it done...

Good luck! are you making it just like the original, or doing something different like tig welding it, or adding something on?
 
nope just going to bolt it all together with stainless flat head bolts. that way i can adjust things or change something down the road if i like. it should look great when done.
 
If this turns into an economic stimulus, I want # 23, haha! My KMG has a beautiful rust patina I have slowly and carfully crafted and developed upon its surface over the years. I refuse to paint her. She's too much of a dirty girl to wear clothes.
 
He is going to make one out of brushed stainless and is going to like it so much he will make a better one out of a gold-titanium alloy and paint half of it red.

That's what I was thinking. Either that or hand rubbed to something like 2000 grit :D

O you know this has crossed my mind a few times :rolleyes:. but i have been thinking a nice bead blast finish might be nice.

I'm thinking that in his spare time, JT can take up hand engraving ( make his own engravers from M-4, of course) and engrave the entire thing.

Here is what Ron Smith did to his engraver's ball.

Oh, that's good Stacy, real good... That is just what he needs, another project... :rolleyes:


:D
 
Now THAT's a tool ! Too many tools these days are made in the 'cheap use it till it breaks' mentality, when what people really need is tools to last a lifetime and hand down to their grand kids. They're much more economical that way

Someday i want to learn engraving like that! but that wont be for a while, i've got little enough shop time as it is currently

That engraving ball is off the hook!

This will be an interesting build on the grinder, looking forward to seeing it develop.

Ok here is what i got so far. In actuality i held everything to + or - .002 or less, not the .003 i was willing to except :rolleyes: . this is 15 or so hrs of machining time not counting band saw time to cut it all which was probabley 6 or so hrs. it's looking good so far. now i just need to drill and tap everything. I am thinking about droping the recever risers by an inch so its a little lower. that the onley thing about the grinder plans that visulay bugs me. on a real kmg the risers are 5" not 6" i think and these are 6". is there any advantage to keeping them at 6"? On the tension arm piviot point im going to use bearing and also on the idler tension tracking adjustment i'm also going to use bearings. should be a smooth operatior.

Do you really need bearings on those points? They hardly move. It would be nice though. I think that putting a smooth bore in the holes and having a greased sliding fit in would be nice enough.

Looks great! Did you mill all of the thicknesses?

I bet he is doing it because envisioned a day when this would happen.....:)

Person drooling over the grinder: "Why put bearings on these pivot points? I mean, they hardly move."

Man I am loving the idea of this whole project. Please keep updating as you progress. Also, didn't you bang up your hand? Doesn't seem to have slowed you down. Frst the curved platenand now this!

well when all you have to do is push a few buttons on a cnc you can make allmost anything with a busted up hand.
