Hi...sorry I didn't see your reply.

I work with AutoCAD all day everyday in 2-D design for restaurant planning & engineering. Determining a W10-49 would be better left to a structural engineer OR look on the internet for specs.

I had to do this when I vaulted my living room ceiling having to build 2-beam to carry load. Found all the formulas. That was all fun on CAD, but a bugger to drywall ! lol PS...it looks great.

Thanx man. Yeah its a lot stronger. The moment of inertia is 2x on the vertical axis and 3x on the horizontal! I just do not know if its overkill :(
Anyway here is a peak of the ongoing CAD of the winch type design :) Screenshot from 2018-12-29 09-04-08.png

Hi,

I'm new to this website. I want to built a firewood processor too. I have a question, I see that you have a tractor and wonder why you
didn't use it as a source power via the pto? This is what I intend to do with a 80 hp tractor.
Btw I have a question, do you think that I can put 2 pto pump on the same shaft, to make like a tandem pump?
I will ask this question somewhere on the forum.
Thank you.

Hello Millet and welcome to the forums. The reason is that I need the tractor with the grapples in front to load the logs on the deck. :) But If I would do it again, I would just have bought a car engine or even better an old tractor engine and I would used that to power the machine.

If you go that route, make sure it has a governor on it. Growing up, we had a splitter that had a 4 cylinder VW gas engine on it with a large single stage pump (20-30GPM?). It did not have a governor on it and was always a pain (had to pull on the throttle as you hit the log and if you didn't give it enough throttle, it shutdown), it was also somewhat cold blooded and hard to start at times. It was replaced with a big single cylinder Kohler (12HP?) and a 2 stage pump and its MUCH nicer to use now.

Yeah, you are right! Car engines usually do not have governors right?? Arrgg another thing to research... :(

Correct, you can find a belt driven governor, but that is another thing to source.

The winch type firewood processor finally got an update. :)
My apologies for the mess!
