Bandmiller2,

 
  As for the rotation of the engine vs blade, I have read and seen video where the use a rear axle diff to change the rotation. I'm thinking that locking the spider gears would be best. Still thinking about using the oem brakes to stop the shaft rotation when I don't want it to move.


I haven't read the entire thread so maybe someone already pointed this out but, you can't weld the spider gears, all that would do is make it a solid axle.  If you want to use the rearend as a reverser you you have to lock up the drive shaft or carrier.  That way the spider gears can reverse the rotation from one side of the rearend to the other side.

 Or you could mount a brake on the drive shaft to use a clutch to engage and disengage one side of the rearend from the other.  But that only works if you have a brake or enough load on the side you want to disengage.

Joe, not my post about welding spider gears, I don't do that. I have on occasion locked one side axle which, as you stated, is the proper way. There are so many things that can be done with a differential, I have seen dandy log loaders using one side brake as a clutch. Frank C.

Simple turn the rear end over and you reverse the rotation lock up the spiders cut one axel off and you have a angle drive  .

Gearbox you are right on. That is exactly what I'm planning to do. Once the axle is locked I will see which side rotates in the direction I want, then connect that up to the end of the arbor on the mill. The rear axle rotates both sides forward, so if you flip the axle housing over then they both rotate the other direction. What was up, is now down so to speak.  Lol

borrowed a miller bobcat welder/ generator from a buddy of mine this afternoon, so if the weather will clear off again, I'll start welding the frame together.

Good to see some progress!  That steel looks to be quite strong.

Yes, Darrel. It is 6x 12" 3/8 thick. Each beam is close to 2000 lbs. Its all my tractor can do to pickup one beam. Good thing we have a boom truck that can pickup 11,000 lbs and the dozer. Once it is all welded together it will be 66 ft long. What you see so far is only half of the length.

Just reading and thinking . 3.90 gears should work if you turn the engine 2000 it will be 512 RPM . 3.73 would be 536 RPM . 3.55 =563 RPM . 3.23 = 619 RPM.

Ok thanks Gearbox. I wonder what rear axle ratio came in a Mercedes 5cylinder turbo diesel D300 with an automatic transmission. I guess I'll have to do some research. I'm thinking they like to run in the higher rpm compared to a truck engine like a 4BT. Higher rpm might be smoother but might burn more fuel.

If you have the truck see how far it is around the tire and devide by 5280 ft. times 60 to get rpm's at 60 mph . If the engine has a overdrive you will need to figure in direct . I think I would shoot for 550 or 560 RPM at the saw to give you a little pull down to get full fuel and turbo spool .

Ok according to the Mercedes sites, an 83 300d has a rear ratio of 3.46 . I don't think the automatic transmission had overdrive back then but even if it does I can probably lock it out.

That figures out to 576 at 2000 . I think they ran those a lot faster (3000 ?) . Can you use cruise for speed set . If you need more power just shift down 1 gear . Still should run 60 MPH .
