Cat 340D Excavator build

[crueby]

The two booms are further along, got the four sides bolted together, ready for the steel pivot plates. They are quite rigid, dont think I will need any internal steel framework other than the plates at the pivot points.

More done on the main boom, made up the steel plates for each end which will hold the pivot bearings/rods. They were milled out of 303 stainless bar stock and screwed in place.





Still need to do some trimming on the ends.





After that is done, will make up the extension plates at the top of the outer boom that the hydraulic cylinder attaches to, and make up the pivot rod bearings.
