Not a chance, they're like bacteria - they spread. Or was it that they're like 2 year old's and they get into everything - never can keep that straight.

Started in on the mechanisms in the stick, got the motor mounted - tight fit...






the opening for the drive cable from the motor to the cylinder:





and also drilled for the bushings at the bucket end for the linkages:

Some more work done on the excavator - working on the linkages from the cylinder to the bucket. The side links were milled from flat bar stock on the rotary table:





The solid link from there to the bucket is being pieced up from a thicker piece of flat bar and two round bars with slots milled in. They will be silver soldered together and then more shaping done.

Got the bearings and rods for the bucket links made...





and silver soldered up the blank for the end link, ready for further shaping:

End of the link shaped...

This morning got the pivot rods threaded and nuts made, and installed the motor in the stick. Here is a quick video of the motion test for the bucket linkage - better get started on the bucket!
