Need to finish this clevis for the boom cylinder and
fabricate the boom clevis over the top for the crowd
arm cylinder, and the boom is finished. It's getting
heavy, too! Put some extra plating in to handle the
extra weight of the tractor.

Mocked up the boom and crowd arm so I can set the
crowd arm cylinder. The cylinder clevis is cut and
ready to weld up and install.

The main frame tacked together. The expanded
steel steps and the masts for the valving are welded. Waiting on the arrival of the valving.
Offset the masts to keep the controls closer to the operator.

This is the slew. There are 22 pieces in it. The pin showing at
the right of the picture(bottom of the piece) is where
the cylinder attaches to rotate the 'hoe side to side.
The empty space for a pin is the actual pivot point
where it attaches to the main frame. The clevis to the
left side of the picture is where the boom attaches to
the slew, and the clevis at the top of the picture is
where the boom cylinder attaches.

Starting to come together. 38 more pieces to fabricate
to the main frame and I can start the final fit and
plumb up the hydraulics.

Had to alter the stabilizer
cylinder ends to get the throw needed. The top of
the 7 point mount for the mainframe, outboard
mounts, stabilizers in place.
Next up, mount the valve to the mainframe, then final assembly!

Made a thumb for the 'hoe yesterday. It's got 2
settings and can be folded out of the way, if desired,
by taking the gusset piece out and folding the thumb
back against the crowd arm and repinning it, and
setting the gusset and one pin aside. Just have to
cut 6 or 8 teeth into each side of the thumb yet, and
shape it a little. The gusset is made of 1 1/4"x1/4"
flatstock welded into an H-beam, with 1x1 square
tubing for ends. 'Bout ready to start cleaning and
priming everything to get ready to paint.

Got a coat of primer on the 'hoe parts(actually, 2
coats primer and a coat of color) now. It's going to
take at least 2 coats of orange.

Did the rest of the hoses. Some adjustments are still needed, but it's about 99% done. It moves well, and seems to have
some power. Did some cool things with the
hydraulics, ran them off the outlet, but we can still
use the outlet if needed.
