Looking at the pre-pro K1 Excavator and the fact that I won't get one anytime soom, I pulled apart my worst example and rattle canned it.
Before and after shots below .... I think I'll leave the wheels red.
It's a jigsaw puzzle to dismantle and I thought it best to leave the jib assembly alone.
Instead, I removed one rivet at the cab end and threw the whole jib in caustic solution.
After rinsing, scrubbing and wire brushing, the jib was like new and to keep it that way I sprayed it with clear lacquer.
Needs re-assembling now. I have the hollow ended rivets to attach chassis to cab but without a proper tool, it usually cocks the job up, so it will get nut and bolted.
Colour is a lot better than this photo shows. Camera not playing in poor light so will try my other camera once it is all assembled.
