Thanks Ron, meant to measure last night and got running in circles and did not do it.
Need to get it down in the shop and too the welder. Maybe tonight, but right now the lawncare business is the all important consumer of time.

Well, did not have time to fix it, but had 10 minutes while Hanna was backrunning to pick me up and looks like there is about a .020" step in front of the bearing between the Cutter head and the bearing, so that is what keeps it from driving towards the PTO.
Now, just have to get it down to the shop, and the old piece out, and I will probably dimple the shaft a bit to give a bit more bite to the grubs.
Got to get the tractor back from the job it is on first though.

Wow! am I slow 
I thought I was working right along on this and find myself slipping to page 4
So, when your tractor is at the job site, it is less then convienient to move these chippers, but we can usually find a way to accomplish the job if we just keep looking. We pressed Lil into service to move the chipper to the welder in the basement instead of moving the welder to the chipper. Pic 124
Crud, Ok, got to resize the photo's. Be back later.
Short version,
Got it in the shop, welded a nub on the grub screw, welded a nut on the nub, backed grub screw out.
Cleaned up all the threads and replaced all the grub screws, took a 1/4" bit and drilled a dimple in the shaft where the grub screw lands, could be a stress riser, but think it will be ok.
So, bit of blue locktite, dimpled shaft, chased threads so the grub screws will go through (I think that was the problem) and I think that end of things is done.
Now I need to take off the infeed chute, and reset the anvil, replace the infeed chute, get the tractor home, set drive line length for the final time, neaten up the coupler on the driveshaft so it slides on nicer and put this thing too use.

Hey Alan, what the heck is a grub screw?= set screw?

Yes, actually incorrect term on my part sorry. I think technically a grub screw is actually the one used to set the clearance / drag etc. on the lathe so there is no play. I should have said set screw.

The neighbor came over last night and gave me a hand taking off the infeed chute and we re-installed the anvil and set the gap (about .030" on the close blade) and then got the chute back together.
Maybe get the tractor home next week and give this thing a run.

Well, got the tractor home from the jobsite, she who must be obeyed let me borrow it for a day or two I think because she wanted the yard cleaned up
Parties you know....
Anyway, sat down and did the final diddling with the chipper on Saturday, spent another hour or two getting everything what I felt was "dialed in" drive lengths correct, dry run a bit, sheilds back on etc. etc.
We ran it for about 4 hours on Saturday, Hanna and I both feeding it.
It worked well for what it is.
We are somewhat spoiled by being around the big Vemeer's, I think my buddy's is a 24" and that kind of taint's you to what you expect.
That said, it will do every bit of the 6" stuff we threw in it (mostly just for testing) and the stuff I got it for, the long straight saplings etc it just gobbled up in short order.
The problems were when we tried to use it as a shredder and bushy, leafy things would hang on the sides, and claw on trying not to go down the chute, but then again, that is not what it was designed to handle.
So, it will do what we intended, should reduce a bit of the stuff coming into the yard, as well as help clear the yard up, at the same time it will give me some chopped up organic to add to my clays and help break them up a bit.
All in all happy with it now. I hate the amount of time I had to spend on it, but I knew that some was going to be spent going in, and if I had to do another one today, there would be less head scratching as I have a better understanding of them now.
Now the test of time comes up.

The biggest thing that struck me, and may be something I change on mine.
On the big one's I have fed, the drive rollers are on the two sides, standing vertical, and they both drive.
On my jinma or whatever it is, the feed roller is on the top in a horizontal position.
It is pushing "down" against a flat plate of steel, ie, one side of the stick is being driven, one is dragging against a plate of steel.
My first real modification would be to put a roller assembly down there so it was pinching between two rollers, I do not think the lower roller would need to be driven, I think it would assist in the feeding.
The other thing, and again, I am used to much larger machines, branches with lot's of smaller branches, or bushes don't want to go down the chute.
With Joey's machine, you get something anywhere near the infeed rollers and it just disapears, anything we touch with the landscape business just comes out the other end as little chips
Then again, I think his last one was over $30K
Will it work for you?
Heck, I just don't know, I wish mine did more, but the $1500 was about all I am willing to spend to deal with the problem I have, so that was the constraining factor I thought hard about an old worn tree service one, but the $ signs can get overwhelming quick when they break (and they will) and god some of those things just scare the crud out of me. I also really did not want to keep up with another motor.
