Chris:I know that if I looked back thru the 59 pages of this thread that I could find the answer myself, but I'm not that ambitious - so I'll just ask. Regarding the chain sheaves, the vertical chain links will ride in the slot that you've cut in the sheave. Will the horizontal chain links ride in pockets, or will they just wrap around the outside of the sheave?Don
looking good Chris and still following along even if quietly Bill
Looking good Chris. Are we going to see some micro forging for the brace rods and U bolt eyes?Dan
Chris coal would work but I was thinking something like this:http://www.anvilfire.com/article.php?bodyName=/21centbs/forges/microfrg.htmI have thought about a few times for some of the forged Shay brake rods.Dan
Chris, I am quietly looking on in awe, what a great job you are doing. I was just up in your neck of the woods this weekend dropping the young lad off at college (RIT) and I was thinking about you on the trip up. I whipped the phone out and shared your adventure with my son and his roommate. Coming from the coal region of Pa, I’ve had the opportunity to get into a few of the Marion shovels around here and they are an impressive piece of equipment. Nothing as old and historic as your steam shovel but the 7400 and 7800 draglines are interesting to get a ride in. My dad worked in the industry and got me in a few times when I was younger .
What an absolutely stunning piece of work this is. The Lombard was also superb and I know that you are a stickler for accuracy. Thus I am very reluctant to point out that the top sheave in your photo of the full size machine has 3 holes - not 4. Hate me if you must!
