Finally Building my Backhoe

[relaqbr]

What backhoe? All I see is a guy wearing dark blue suspended in mid-air.

You need glasses. There is a black blob and two black rings behind him.

There's something behind him that looks like a small engine.

Sketchup.

It's the only thing I have been able to learn on my own.

If anyone wants the actual .skp file, PM me. I can send it in a .zip file.

It looks like Sketchup has served you well.

Here's what I got done today. See the attached picture. I only got the one bushing cut out and in place since I spent most of the day chasing other projects with the kids.

It's a good tight fit in that hole. I don't think I'll weld it in place yet. I may want to be able to move the bushings back and forth to allow me to get everything flush against the floor to keep the boom straight and true while I weld it all up.

What size tube are you using for the boom?

As somebody else already mentioned, theres not much meat holding that bush in place, because you use reasonably thin walled tubing. You could reinforce it a lot by bending a not too thick piece of flatbar over the bush, touching the inner of the tube on all 4 sides, and weld that in place. It will greatly improve the stability when the boom is laterally loaded.

The boom is made out of 3" X 4" X 1/4"

I'm planning to put 1/4" plate around the ends of the boom to enclose the bushings.

I'm still debating whether to try and run the hoses up the inside of the boom or to zip tie them to the outside. If I run them up the inside, I'll need to leave holes for them to enter and exit. One hole will need to be in the side at the joint in the middle of the boom.

Looking good IFarmer. I would run the hoses on the out side. If you have any leaks they will be easy to find. Also if you run them on the inside you have to have room to get by the pivot pins.
