Red version: building a lower space frame
When complete the red version looked like this with the lower wire space frame attached:
The red version was the first to be made using low density polyethylene board.
A high-density polyethylene (HDPE) version was made before this, which was the first to feature the present basic design but the HDPE was much denser and too heavy.
At some point I made a kind of spaceframe cover using gas welding rod and wire, soldered together.
The objective here was to create a similar space frame for the underside which would also function as the rear legs.
An under belly was made and slung beneath the main body.
The welding rod sections are joined by wrapping them in steel wire and soldering.
The next step was to modify the LDPE leg and attach it with rods to the main body.
From then on the space frame was built up and the spaces between the wire struts was filled-in with a kind of  lattice structure using wire.
This process was then repeated on the left side.
The whole structure was then removed and painted.
The claws were attached.
This assembly was then reattached.
The result:
Nb: a larger rear claw (with slip-clutch) has also been attached.
The next task is to modify the front leg and claw…
