That doesn't look to be that big of a tree, I think I should be able to pull it on flat ground. We'll see.
As for cost of material, so far I am into it for two hundred fifty bucks, that's with the shaft turned, bearings are on the way from McMaster Carr, 60 tooth sprocket from surplus supply, a few tidbits and the stuff I pictured from TSC. Right now I have about two hours into it. I have a bet with my buddy that I can build it for under 300, I know I can't but I bet it won't be much more.
Freeze the bearing and heat the pipe to make things go together easier
What kind of needle bearings are they? The ones with the thin drawn cup aren't super critical as to hole size. If they have a thick ground outer race the hole size has to be spot on, like a ball bearing. 1.25 isn't an accurate enough measurement to know if they'll go in. Does that mean 1.2500?
With bearings you pretty much need to know the exact hole size to know if they'll go in. If you get it part way in and get it stuck you have a problem.

I'd call it a medium log, but big for my size tractor, it was hemlock fresh off the stump so it was heavy to. A few specs to compare log for log for when you pull your first log. This was used for main carrying beam, the first but cut sawed out a full 7-1/2" X 13-1/2" X 20' 2" , so the first but log topped out at around 17" at 20' long then there was another 14-16' log after that, the final top was 6", total length was around 34-36'.
So to get my 5 stars, you have to pull that size hemlock log with your $500.00 pto winch uphill at a 30ー slope, and winch it at the same winch speed. I recommend a 5/16/8mm high strength winch cable, I have 8mm on mine.
You wouldn't think a piece of 2.5" OD x .250 wall round DOM would be that hard to track down! LOL I need about a 4" piece. I may end up back at the machinists.
I'm just waiting on my stuff from surpluscenter to get here. They don't seem to be real quick on shipping like we've come to expect from some places...lol
Stay tuned!
