Chipper Jinma chippers

[JerryK]

Dougster, still working my 8". I'm ditching the yallar device mine came with to disengage the feed roller. I'm going to put a pull cable around the mouth of the chipper, just behind the sheetmetal lip so branches probably won't get to it. I fab'd up a latch that the cable will operate to lock the roller when the cable is yanked. Pulling on the cable [or pushing] will disconnect the feed roller, and it will re-engage if you don't pull the cable far enough to lock it. Anyway, helps pass the time. Have to come up with some way to unlock the devise after a panic stop yet, and paint, etc. Got lots of time, and most of the metal I am using is just hacked up parts that came with it.

WOW

I didn't mean to set off anything I was just curious. I very much enjoy hearing the bad but also wanted to hear some good if there was any (and there seems to be ) .
I have 22 acres of pines with several large brush piles left from the last clear cut that I would like to make go away with out setting them on fire so naturally I am looking into chippers and other methods of disposal.

Please continue on with the documenting of your chipper repairs and successes.

Guys

I have followed this thread with great interest as I too am looking for a chipper.

This may not be a good question to ask but as it has been going on for quite some time and I was wondering has anyone actually chipped any brush yet

Sorry about this just had to ask .

And thanks for sharing your trials and tribulation before we all bought one.

Why yes I have... I'm glad you asked Jack. I'll go out to one of my chip piles and get a photo (or two) for you, tomorrow.

Okay Jack, here are the promised pics:

Building the brush pile with my Bull Grapple.


Brush pile partially reduced.


Size of chips when knive to anvil distance was about 1/4".


Size of chips when knive were set 0.02" (book says 0.01-0.03")


If possible, don't chip green wood (especially pine). A friend did that and had to basically take the chipper apart to clear the needles that had really gummed up his chipper. I had an old Christmas tree in that pile and the chipper sucked it up with no problem.

One other thing I've done is coated the knives, anvil and chute with "Fluid Film". That stuff works great at keeping the tree sap from sticking. Even with the Fluid Film applied, I would still recommend against chipping green wood. It just avoids a lot of gumming up the works, that's all.

When I first started building my brush pile, I was intending on burning it and wasn't careful about mixing dirt and brush. Now that I've STOPPED THE BURN, I'm having to shake out the dirt and debris as well as possible to avoid dulling the blades.

Quote From Will: As for the modification of the feed roller drive shaft "U-joint", I had to replace one end of mine w/ a 1/2 inch impact wobbly.
So far so good with about 4 hrs of use.


I did this too. I used a wobble impact socket. Works well and will probably last forever, but Im having trouble fastening itto the telescopic shaft in a lasting fashion. I have adhered it into the original socket that stripped out. It breaks loose occasionally on max sized stuff when the roller hits its upper stop. How did you fasten the two sides of the swivel?

Thanks for the pictures Mad I am very encouraged and impressed with the results.

Dougster, more pictures of my feed roller lockout for your amusement. Got some real USA equipment yellow paint on it. I put a 1/4 20 bolt on it that sticks up thru the slot in the original equipment guard to unlock it after it gets locked up. I welded on the ball bearing cable guides onto the corner of the chute, too. [with all this free time I have, send me your chipper and I will fix it up for you. I PROMISE I will send it back, someday.........]

Dougster, having fun with your weddings? I'm cleaning up the mess in the barn, and getting ready for the big 'setting of the knife gap' ceremony tomorrow. Today is 'watching of the NASCAR race & barley pop sampling day'. Here's updated pictures, don't let the big 5 1/2" feed roller scare you, it's hundreds of miles away....

Hi Jerry - Great pix! I'm saving them all for future reference. And that boom pole seems to be coming in very handy! Must be a really heavy-duty one for that load!

My family weekend activities are almost all done... Thank God... but I'm staying out of this thread anyway. Please don't be offended if I don't reply... I've just got nothing more to contribute here.

How did you fasten the two sides of the swivel?

On the drive shaft end;
I took a sacrificial 1/2 drive impact socket, cut it in half.
Welded the square drive 'half' onto the end of the drive shaft.(old swivel was removed)
Topped it off with a large washer for the spring.

With that done, the impact wobbly 'plugs' into the end of the shaft.
The other end of the wobbly fits over the original 1/2 square drive stub on the drum.

(if this don't make sense, I've got pics)

Yup, I'm done here, too. On to the 'replacing of the oil lines to the filter/cooler ZR2 project' in a couple days. Trying to get my inside stuff done while it stays cool out in the barn. Have a great summer, Jerry.
