Stump grinder project - need some input

[woodlandfarms]

I built my own as well (fully hydraulic version). I am very interested in how you mounted your wheel to the system, and who built your wheel.

 

[Jim Timber]

I built my wheel, and the hub it's bolted to.

 

[woodlandfarms]

Did you build the flange to hold the wheel?

 

[Jim Timber]

I made a hub out of a piece of 3/4" plate and welded it to the female spline adapter that came with my gearbox.

 

[Jim Timber]

Then cut a counter bore in my 3/4" wheel to match the OD of the hub.



Then flipped it over and started laying out my pockets.



Didn't like how crowded the 4th row was on 24° spacing, so I added another hole and moved those pockets over.

 

[Jim Timber]

With the wheel pattern decided, I then drilled the hub to match.

 

[Jim Timber]

My 3/4" plate was a drop from laser cutting and is 23.75" IIRC. I never bothered to true the edge of it. Runout is minimal, and top speed is only 800rpm or so. I run it closer to 670, because that's a lot closer to my torque peak.

Wow Jim, that's a project to be proud of!
Gotta see if Hughesnet will let me watch your video in under an hour!

Lol took 10 to upload via AT&T out here.

Just watched it! Fantastic.
What did you learn? On all my projects, there's usually a few things I would "tweek".
