Rather that making new threads for each part or tractor that I work on I figured that I would post It all in one. I'm involved in building 6 tractors ( 4 jp's, 1 mod-xr  and a super) so a build project thread would be tough.

I will give some description's as I go and welcome all  constructive criticism.


I spent some time on the lathe last night and made my rear wheel hubs. Here's some pics of what I have so far. I still need to split them and put the holes in.






Here's one of the Jp's were working on for my friends daughter
It has a foote  6 speed and a 12hp briggs. It's also going to have a an axle mounted brake hat.

Here's what I'm starting with. AYP Craftsman for the new  Mod-XR class that were running at our track.

I'm waiting on the rear tires in order to make it a rolling chassis.

Finished  the rear hubs today.  I wish I had more money than time  They took a lot longer than what I thought they would take. If I were to sell them I think I would have to get $300. bash



Also finished the trans plate



And cut some keyway's in a solid axle for a transaxle

The only bracing I have in it at the moment is a 1" square tube running from one end to the other on either side. I will be adding more as I go. I still need to put in the steering column support and the trans plate.
I will post a pic tomorrow of the underside.

Are you planning on connecting the stiffeners to the front axle?

Yes. I ran out of time the other night and had to get some primer on it before it turned to a pile of rust. Been wicked (Mainer for a lot ) humid here and the frame was sandblasted.

Ok so I got my front end together and my ackerman is backwards by 5 degrees. If I place the tie rod in the same holes on the spindle arms.  I know the is a thread on here about it and how to correct it but I'll be darned if I can find it.  Any help would be great.

If I tip the arms out more would that correct it.







Thanks

No matter what the shape of the arms is, to get the ackerman correct with a front tie rod the tie rods must connect outside of the kingpins.In other words, the distance from center of center of the tie rod heims must be longer than the center to center length of the king pins.

Thank you Rooster!!!
