Chris,Do the front tracks turn at all? Or do they stay fixed and only the rear tracks turn to steer the crane?Kim
Thanks Chris, I believe I follow now.And, you're trying to document the original configuration of a cobbled-together Frankenstein machine! That's got to make things a little more difficult!Kim
Hi Chris,As you know already I have been inspired by your recent work on the very successful Lombard and now the Marion Shovel.Your 3D drawings in Fusion 360 give a great example of what can be achieved with realistic and detailed illustrations of the workings of these rather complex machines. I am still working with my thoughts on Ruston-Bucyrus Shovels which in many ways are similar to Marion's products. It seems that much of the original information on the R-B designs has been lost along with those of Ruston & Hornsby as a result of the takeovers by English Electric and then Siemens, neither of which were likely to have an interest in shovels. However I am still collecting whatever I can find, including various sources which have found their way to the Antipodes.I have been a user of Autodesk Inventor for some time and I want to compare the results from that very expensive programme with your work with the free ( for hobbyists) Fusion 360 which originates from the same software house. I wonder whether Inventor which has all sorts of bells and whistles but was 'invented' some years ago would perform as well as Fusion 360 which surely must have more up-to-date origins. Sorry to hijack your thread.Jerry
