Hi Chris, Looks to be an interesting project with the research etc. As to the scale question, I am presuming you are keeping true to steam operation(?), thus the question might not be the overall dimensioning but practical dimensioning of operating components and what your manufacturing capacity is. There are plenty of G1 railroad cranes of similar type,some scratch built, but I have not seen any steam operated jobs other than 5'' gauge or bigger. Maybe a similar general sizing that complements your Shay and Lombard would just about be big enough for steam operation?? Interested to hear your thoughts as to how far down in size you think is viable for an operable steamer. Regards Paul Gough.
This looks like it will be really fun to watch. I'm glad you have access to the 12" to 1' model to get measurements. Are you sure that the whole beast is there?Alan
The early drawings are coming along nicely Chris. I got to thinking about the operation of this "bad boy" and was wondering if you happen to know how large of a crew it took to run it?Jim
Think I may need a 50lb sack if popcorn for this one Chris. Looking good on paper so far though.Bill

I just heard from the historical society, the visit from the park service guys from Steamtown has been moved back a week to mid November, so one more week to get the rest of the 3d model in shape before then. The fine details of the engines, drums, clutches, and tracks will have to wait until I get in for my own photos and measurements since the ones I got from other sources don't have any close up shots of them. Still lots I can get done till then.I am going to be taking a side trip this week to design up a modification to the log advance ratchet mechanism for the water driven sawmill at the museum in Maine. They want to cut the advance distance in half to reduce the stress on the blade, and were going to rework the gears till I pointed out that adding a second set of pawls half a tooth over would mean only having to change a pivot point on the lever. Measurements are coming tomorrow, and I will be drawing the new setup in Fusion for them.
