Dirt Scoop Problem

I did a partial refurb of the scoop.
I cut out the old pin bosses and welded new pipe in the two arms of the trip mechanism. Refastened the bucket bearings to the over-beam -- bolts were loose.

I made a nice containment for the compression spring under the trip lever and adjusted the travel so it would dump.

BUT . . . I really didn't think I could get away with the off center catch welded to the bucket and sure enough it needs reworking.

So here's the deal:
When it is locked, I can trip it by a light load of dirt or by stomping on the bucket edge.
So other than the obvious, like centering a new stop and putting a fresh edge on the locking arm, are there any voices of experience with some good suggestions?

Should I put an slip-opposing bevel on the new face at the end of the lower red arm and and a conforming pitch to the welded stop?

Obviously I'm only getting partial contact as it stands. The arms were totally sloppy as far as side play, so no wonder. There's no side play anymore.

I'm glad I left the stop till last.
:)

Thanks,
T

Look at the top picture. Here's what I would do:

I would go about 2/3 of the way up the "boomerang" L-shaped piece that is the catch. I would
weld a piece of angle iron to the bottom of it. Then I would weld a loop or nut or something to the
outside of both of the straps that run on either side of the catch. Go to the hardware store and get
a decent sized spring. Hook it on one loop (nut, whatever) take it around the bottom, and hook it
on the other side. It will keep upward pressure on that boomerang piece which will keep it against
the notch on the scoop where it catches. The piece of angle you welded on it will keep it from
walking down the release lever.

You don't want to add a bunch of weld or anything to that catch. You won't get the boomerang
catch to slip past it to dump if you have a heavy load of pressure on it.
 
NotJustAir,

Thanks much for your help. I confess I couldn't understand exactly what your plan was, but the "spring" aspect of it inspired me. I wanted to keep everything as simple as possible.

I started by making a 10 degree fresh cut on the arm so that it would be square to a new square stock stop then went to work on an assist return spring. I added a small extension to the rope pull lever so that when yanked it wouldn't slip off the pin coming up to it. as you can see, I had my 40 year collection of springs to choose from. :)

I tested it and it works great, but when fully raised, those sloppily welded on pieces of angle iron on the bucket sides, catch the tire lugs. I think I'll cut them off, cause now, when
the bucket is raised, it tips nicely back to contain the load.

Thanks again,
Terry
