Log boom grapple build

[Jim Timber]

The downside to flow control is the lack of additional torque from gear reduction.

Hey, One with the Offensive Avitar, any progress on your build here?



Mr. HE

I've made very little progress, I'm still trying to figure out my landing gear. I did get the jib bored and bushed and cut on the angle. I think I just figured out how I'm going to make the joint at the main boom and jib. It all boils down to money which I don't have any extra right now. It's been so cold that I haven't felt like starting the stove in the garage only to have it take all day to warm up in there. I may start it today though, just to dry things out a bit. Even though I haven't made any physical progress I have been making mental progress. I constantly doodle different pieces getting my head wrapped around what what's going to look like. LOL I'll keep you all posted. I could have used this thing last week!

Good points which I hadn't considered. You are looking at it correctly. I don't care about it slipping over the axle, I was going to weld them on in place. I may take your advice and weld them to the axle, that way 1) like you said, the same bearings won't always be under load and 2) if I do brake the axle shaft I can still slide it up out and replace it and salvage the bearings.
thanks,
dave

I have discovered that the pipe isn't perfectly aligned over the axle tube so I think I will have to weld the bearings to the pipe instead of the axle. It's off by like an 1/8" run out.
