Let's start over......
Morning. Here is the new project that I went to get yesterday she's pretty rough but that's why I got it for what I did. It's 79 John Deere 317 so a rebuild of the motor is going to be done because the Series I Kohlers were known to have a lubrication problem. This is going to be a fun project I can't wait to get started on the tear down and then start building the loader and backhoe subframes.
Here are couple pics.

I am looking to build the loader and backhoe subrframes and booms as light and as strong as possible for my procject 317. The welder I have can do 5/16in max thickness steel but I don't really think the tubing needs to be that thick only the fishplate/gussets that the hydraulic cylinders mount to. I am a complete noob to steel, but I have been around enough heavy equipment to understand how they are built and that weight is your enemy. The lift weight limit on the loader boom is going to be about 550lbs and the backhoe is going to less than that but it's going to need to withstand pushing/pulling heavier object's than what the tractor weighs which is around 900lbs. I have a pretty good plan in my head on how to build this and I'm going to fab everything out of wood first and use the wood as patterns to cut and fabricate the steel versions first to limit the chances screwing up a piece of tubing. The loader boom is most likely going to be 2x4 the backhoe dipper and stick boom are going to be 2x6 or 3x6 and all the fish plates are going to be either 1/4in or 5/16 with reinforcing washers of the same thickness welded on for the cylinder pivot's. What thickness and type of steel would you use if you were building this for a customer?

Yup, plus he was yelling at the Vandy fans as they were leading him out. I'm pretty sure he will be expended for a couple of games. That was a cheap shot.

But yea, looks like a fun one to fix up.
Dave, have you seen this site??? Just might help. http://pf-engineering.com/home.html
The mini backhoe would be handy as hell. AND it would be a good counter weight for the loader bucket lol.
Dave could have one Deere set up to cut grass and the other with the fun stuff.
I would stick with square tubing instead of rectangler tubing. Square cost way less and is just as strong. 3/16 - 1/4 would all you would need I would think. 4x4 - 6x6 would be fine. For the pivots, be sure to cut or drill holes and weld in a piece of pipe all the way through with a thick washer on each side. 1/4 - 5/16 plate will do just fine for gussets and reinforcing.
