1/16 Bucyrus-Monighan Walking Dragline

[9W Monighan]

A little update on my riveting progress. I finally got all of the angles made and all but 8 are fastened onto the brass sheets.

Milling 3-1/2'' angle to scale = .218''


One of the walking shaft bearings I made about 10yrs ago.


Drilling the vertical support channels.


A few angles almost ready to rivet together.


Tapping some 0-80 threads.


Installing the .040'' dia. rivets by the hundreds. These are squeezed
in a little press I modified.


The last angles fabricated and ready for riveting.
