I think that by the time we're all done with all the patterns, we'll need a whole building just to display patterns!!!!  Not that I would complain in the least bit  ;D

Thanks everyone for the very kind words.

Mike, I completely agree with you. Part of the value in us building #11 as close to how it was originally done as is reasonably and practicably possible, is in providing a way for the public to see how how it was done. If/when space becomes available for more interpretive exhibits, I think it would be really cool if there were displays regarding processes/features like the Russia Iron, patterns and castings, or any of the many things that go on at the museum which are really unique, but that the public might not see on a regular weekend visit. For now, I'm glad that we have the forum to use as a record and a view into how so many of the projects at the museum are made possible.

Hi Alan,

I'd like to propose that someone write a couple of articles for the WW&F Newsletter about some of these things. That would also be a record and a view into how so many of the projects at the museum are made possible. The newsletter has over 1100 readers, so between the forum and the newsletter, this information would reach a lot of people (admittedly with some duplication).

Who might that "someone" be? My crystal ball is cloudy, but I think I see a first letter "A" and maybe a first ;letter "D."  ;)

The Winter #11 Update

Since my post in October, I had the chance to spend a few holidays at home, including a nice lengthy stay over the Christmas break. No new patterns (for #11) have been made, but each one that I had started still had a lot of finishing work to do.

One of the biggest hurdles was producing the core boxes and prints for the two journal boxes. In order to reduce the machinist workload as much as possible while maintaining good margins, I had to try out a different core box construction method. For both of the journals, the core box for the bottom half comes apart on all sides, negating the need for draft in the core box itself. Bernie's feedback regarding my ideas was indispensable- I wouldn't have been confident in attempting it without it. The cores were a bit of a brainbender to figure out how they would go together, while maintaining accuracy and repeatability but I am very happy with the results, and will be keeping this construction method in mind for future patterns.



The core box assembled:


And apart:


The lead truck journal is nearly a carbon copy in terms of pattern construction



The eccentrics have had a fair bit of work done. At last post, they had been roughed out, and were awaiting cleanup. In order to produce, I used a template and a follower along with a very long, 1/2" end mill to clean up the excess. At full extension, the end mill had a fair bit of chatter, reinforcing the reasoning behind using big end mills when you have to have a lot of extension. Too bad they won't fit in the router table! Nevertheless, it worked pretty dang well. I will also be keeping this in my back pocket in case it comes in handy for more complex interior shapes.

The eccentric, and it's template


On the router table. I only raised the end mill 3/16" per pass, but wanted to show how everything worked together.


At this point, the retaining ring rattled off, and the template guide got caught up in the end mill. It was terribly exciting. Fortunately, the template guide was the only casualty, but I had to stop at this point until a new guide could arrive.



While I wasn't able to make the three more patterns I'd hoped for #11, I did spend some time making a few new patterns for another project that's in the works. All of the other patterns received a lot of clean up work and attention. Applying the fillets takes a fair bit of time, and with everything all batched together, there were many days just spent filleting, and cleaning them up. All of the patterns (save one) are now either being finished, or are being prepped for finishing. As much as I loathe the finishing process, it's great to see things wrapping up. I had been worried that I bit off more than I could chew this year, and I think everything should come together just in time for a trip Down East this summer. I'll be glad to free up my bench space, but the car is going to be pretty full this year!

Alan,

WOW!!!!!!!!!!!!!  As soon as my frigid cellar gets warmer, I will continue to add to the pile.  This has been a brutal winter among other things which have slowed me down.  You are an inspiration.  We need more youth like you.

Alan…no question about it, we need to invent some new superlatives to describe your work. Thank you so much!

Hi Alan,

Those patterns are some NICE work!  Thanks for posting the photos, can't wait to see them in person.  Any idea when you may be coming to Maine?

Thank you all so much for all of the very kind, and wonderful compliments. It's an honor to be working with this museum. I can't wait to see the pile of #11 patterns grow some more!

Stewart, I'm happy to say that my father and I hope to make it back up around the end of May this year, and we're really looking forward to it.

Just noticed that this thread has passed 40,000 views, the first one (by far) to do so.  Not bad for a locomotive that doesn't even exist yet.
