R5's transport sledge 'upgrade work' pt3

The two 'fixed, in-line' wheels, where good, but made pushing in directions a bit difficult at times.

So wanted to replace with two more swivel casters. I also wanted to reduce some of its weight and clean up the lines a bit. So the two protruding sections (holed wheel slots) where marked and sawn off.

I then marked and drilled two holes for the threaded swivel casters. I used t-nuts this time rather than trying to fit normal nuts, like on the two the other end.

Not much lighter, but is a bit and is easier to move when R5's not loaded up on him. Defo easier to move around.
