A spreadsheet would be sweet. I am always thumbing threw my notebooks, I make my notes in different note books for furture references.

I'll work on it.

So where was the failure did the oe axle mount that you stiffened up bend? You are killing me not knowing were the failure was.

I'll take a pic tomorrow AM when I'm out feeding the horses and post it.

Horses are fed and out, had a quick look at the underside of the trailer to analyze just what gave out.:confuse:

It seems that the triangle section I made with the pieces of 1/8" flatbar made the center of the support quite strong, so when the axle started pulling it just pulled up the center of the sheet metal. It folded faster than Superman on laundry day.:wallbanging:

This shows hows flimsy the sheet metal this thing is made from, so I will probably add some fish plates to the sides for my new brackets to bolt through.

I will repair this though, I want this whole mod to be able to be removed and returned to essentially stock simple if need be.

BTW the axle rod did not bend neither did the trailing arms.

Have a good one fellas, off to work!:wave:

Having it hooked to the four wheeler in the one picture puts it in to better perspective. I originally thought it was a lot bigger then what it is(that didn't sound good I know). I think you are on the right track, especially once you get it reinforced.

So much to say, but we all will forgive you for your bad phrasing George LOL.

Also, looking at the sprayer I just see a very complicated suspension project. I would probably abandon most of the current setup by now and use a wide axle with a link on each side going to the front (make a trapezoid with the frame to get rid of sway) and then use 2 shock absorbers for a car, one on each side between frame and axle (also a trapezoid methodology). I know that is complicated wording but a simple theory that give you suspension. Also I would add larger tires lol.

If you plan to be able to put this back 'stock', I would start building from the axle mount out.

I think you're exactly right here... I'm going to look into the shock idea and the second "link" to the arm for stability. This is like a mental deficient trying to invent suspension for the first time huh? "Look at Rainman, he nearly bankrupted a casino and he was a ruhtard!"

I liked my torsion bar idea, but don't like the pin thru the tubing and shaft connection method. A splined shaft is the conventional way to do it, so I was thinking on some options that would give a more positive interlocking between trailing arm and torsion bar.

That's what SHE said!








Sorry, I couldn't leave it alone. hehe. :D

Yes, the sprayer is pretty compact. Probably good for spraying 1/8th acre per fillup maybe?

Spline connection is not the only way for a torsion bar hookup. Might want to loom into a leaf pack style it is a sqaured end with a grub screw. Just an idea.

If it was me I would keep the arm you built but add one more leg that makes it look more like an a arm that could attach further inboard possibly using a hiem joint.

This is a great build to follow, love the pics. along with the explanations. As a sheet metal worker I would TIG weld, mostly stainless steel, aluminum and copper along with some steel. I liked welding stainless steel the best.

I love the tig welding too. I just bought some Stainless Filler rod. I had read that it was better than the regular steel filler rod, so I tried both. I found that I had less impurities in my welds with the stainless. Maybe it was coincidental, but for a few bucks the rods are sure to stay un tarnished as they sit for long periods unused in my shop.

My pal has his first off road truck race this weekend, so we've been burning the midnight oil trying to get his truck built. It has consumed all my time, so I'll be back on the sprayer Monday. He's a sheet metal worker as well! My welder and fab tools are at his shop now anyhow, so I can't even steal a few minutes out in the shop on it...

Still just sitting there waiting to get welded... doh!
