Hydraulic Problem Solved.

[Fawteen]

Using the advice of a guy over on the Shopbuilt forum (see the link) I built a "redneck flow divider".

Basically you put a tee in both lines and connect the tees with a gate valve. That allows you to bleed off some of the pressure to the return line.

Works pretty good, adjustable on the fly. Best of all, I was able to plumb it up out of my parts pile. I'll still be gearing it down more as soon as I can put my hands on a bigger sprocket for the pump.

Thanks for all the input from everyone.

Next hurdle is trying to dump an actual load.

From what I can see in your pictures on the other forum, you're gonna have structural problems where the hydraulic cylinder is tail hold on both ends. You have the C-channel going the weak way, I'll bet anything you'll need to brace them, at least with a V going back to the side frame.

I can't weld worth a darn, but that would sound right to me, Puddles.

There ARE braces going from as low on the fixed mount of the cylinder as I could get them, going to the main frame about halfway forward, just above the axles.

Learned that lesson the first time I tried to lift the empty bed, even before it was decked.

I may box that rear member, or if you have a better way to reinforce it, let me know.
 

[Puddles]

Maybe something like this, try to use the same size / width / height material.

This shows the bracing to the rear (fixed) end of the cylinder.

I like the idea of bracing that rear cross member on the subframe tho. I'll have to see what I can scrounge up for material.

After cleaning up the plumbing I loaded about of yard of wet compost on it, and dumped it okay.

Definitely going to have to re-gear it, it was ALL that 5.5 Honda wanted to lift that load.

It might just be the picture, but it looks like that box tube is already bowed?

Camera distortion.

The push point on the dump frame has been triangulated since that picture was taken.

Next time I have the bed tilted up I'll take some more pictures.

Well done 14, I can only think of about 5000 uses for that trailer! I also build/repair from stuff on hand,almost to the sake of fault. Last Saturday spent over an hour looking for then making a rubber wheel for a 3 inch castor out of a old boat trailer guide; only to have the other 3 caster wheels break when I put a load on. However, that looks real good. Later, Dan

Good to hear you got it figured out. There are very few things as satisfying as building a complex project out of simple parts, and not spending a dime doing it....

If the gate valve is just a plain water (plumbing)valve it can burst due to more pressure than it is rated to handle,i have had it happen.BE CAREFUL DON

Puddles, that's what I was trying to suggest but
didn't have your computer savvy to show a pick. LoL
I still think the pump may be turning too fast. I
would put a tach. on it to check the RPM.
