1/16 Bucyrus Erie 25B

[9W Monighan]

The slewing ring measures 60''dia X 47''dia in the hook roller grooves X 9''thick.I count 64T on the internal ring and it looks to be about a 42'' PD. The pinion appears to be 16T. I don't know how you're going to cut the internal ring though. I have measurements for the A frame and the correct wire rope sizes and lengths. This IS going to be a dragline ,Correct? I can also get you some pictures and sizes of the fairlead in the spring when we have our outdoor show. The books I have show alot of details. Especially the 22-RB books.
