The difference between ideas and fufilment of said ideas is success vs failure, but there is a third way, The Salvage Operation

I hate to admit to being incompetent. The point where you give up is the point where you fail. But, I have some issues. I have been a bottom feeder so long that scrounging is instinctive. Even to the point of compromising a good idea. I have been confused about whether my Uncle is mad at me or not for so long that I am always on edge around the shop, even though I am over 40 and it no longer matters!
So, I am trying to build a light weight sprayer to pull behind a fourwheeler to spray wet and muddy fields.

It was a good design. But the execution of that design has not worked perfectly.
I continually warp the metal when I weld, even though I should know what I am doing. (I've read the book) I do stupid things like use 6013 rod instead of 6011 because I found some behind the welding bench in the shop with the flux chipped and I don't have to pay for it. I switch rod sizes with out adjusting the welder. I forget to clamp the work, or I weld too much on one side before turning it over. I forget the chip hammer. I get rusty metal out of the scrap pile, so I don't have to pay for it.
I mix .082 and .120 wall tubing and then burn holes in the .082. Instead of ordering 3/8 3x3 angle iron I used 1/4. I center punched a row of holes and somehow got them out of line.
The trailer is no longer light weight but may bust in half. (Where did I put that .082 tubing)
I did buy a welder.
It is pretty neat. It is a Lincoln Ranger. Here is a photo. The fellow made me a deal. Can't resist a deal...
Have a nice day.

PS: To those who faithfully leave comments and whose blogs I usually leave comments. Sorry I have not responded. I am trying to get this trailer done and figure out pig feed rations so I have not been wandering about the internet.
