DIY Farm Impliments

[Ironman]

I figure it's best to start a clean thread on this build we talked about in Math Help
Got many ideas and just scribbled them down and flopped back on the couch. I'm finally getting over this cold and I detected a trickle on energy yesterday so I've started the build of this critter.

I decided to go with a couple of rusted up drive shafts from something I scraped.
This will be the eccentric or crank, or whatever to shake things. After watching those video's I posted, I decided that the stroke will be what ever it is, I can't see a problem if they manufacture something like that.

Yesterday I hammered together the A frame, and today I tack welded the bearing box into place. This is all leftovers and scrap so it ain't pretty.
y next job is to mount the blade in the mill and sharpen an edge, then I'll tack weld it to the side bars and see how it looks.
I had given some thought to using some tie rod ends from a 12,000lb steering axle for the crank ends and the end on the blade lever, but not having a spare to push into a hole in the plate to swage the taper in, and not knowing how they would last in rotary motion killed the idea. Pressing is the only way I have at hand to do a short taper.

Pic 1 is a similar driveline in the way I will use it
Pic 2 is showing what is done
#3 and 4 is self explanatory as to what the U joint will do
So this is it, at the moment, If I have a good day tomorrow, I'll report more.
