Bernie has been hard at it making another pattern. This one is the Follow Block for the Saddle Shim.

The photo Mike posted is the "follow block" used in the casting process.  It will be used to support the shim pattern.  It will also be used to help assemble the shim pattern.  When a pattern is curved and does not have a flat surface to rest on the follow board, a follow block is used in the initial ramming stage.  The shim pattern sits in the follow block during this stage and when the flask is turned over to ram the second half, the follow block is removed and the second half is rammed up.  Shortly I will show the shim pattern fully assembled.

The new boiler for #10 is a slightly larger diameter than the old one so the saddle shim has two curved surfaces--a smaller radius to rest on the saddle and a larger radius for the smoke box to rest on.

Mike, thanx for posting this as I still haven't learned to post photos.

Really enjoy seeing fine craftmanship  used to scratch-build  elements, tools to rebuild an historic, useful machine like No. Ten.

Bernie,  can any parts of this pattern be used for #11 castings?  Can't wait to see the finished product - another work of art..

No problem Bernie. I enjoy seeing your fine work, and I know others do too.

John,

This part is strictly for #10.  It is a one-off and the pattern will only be used only once.  #11 will not need this part as the saddle will be properly contoured to fit #11's smoke box.  This making of a pattern for one casting is typical for steam locomotive repair.  The part is important for the repair but only one is needed to keep the choo-choo running.  I have made several patterns and in the middle of making clam shell door patterns for CNJ 113 which will only be used once.

This kind of project would be a good candidate for the 3D sand printing process discussed in earlier posts.  Since I don't do CAD, I still do things the olde way.

Does anyone at this point have an idea when the No 10 will go back into service?

No particular date, but we are steadily working on the boiler parts.  The Mountain Extension is consuming a lot of time, but operationally it'd be great to have 10 back, and we haven't forgotten our 21 Campaign supporters, so we forge ahead on all counts.  Just don't dare give dates with so many irons in the fire...

see ya

Setting dates for a restoration can be a dangerous thing.  Ask the Western Maryland Scenic Railway about their ex-C&O 1309 rebuild.

Trying to shape the backhead has been slow due to the size of the boiler and the need to compress the steel as it bends. This has required a lot of figuring and tooling modification. This learning curve will make #11 go a lot earier and quicker.

As supporters of both WWFRy and WMSR, we were concerned about whether the resources i.e. money in particular, would be difficult to raise in the initial time frames for the WMSR 1309.  AS far as I currently know they still need around $500K to finish the job.  We have seen the engine under cover at the B & O museum in Baltimore.  It is an impressive freight engine. We are looking forward to its completion.  Barb & Gary Kraske

I need to clarify my passing reference to the Mountain Extension above.  The work on the Mountain Extension has taken days away from working on 10, specifically developing the jigs we need to properly produce smooth deep flanges, but I should have been explicit:  that’s not an excuse or assignment of blame.  The Mountain Extension was a decided shift in priorities, of which I am fully behind, because of organizational developments which we didn’t expect.

The Mountain Extension, which began when we were donated the Moose Brook Bridge, developed a definite, hard timeline after we researched the permits required to install it.  In short, the permit which includes the bridge installation is actually a permit to rebuild the railroad.  It expires in 2 years.  We wanted to settle the permitting issues before getting too far along with the bridge rebuild.  Therefore, the permitting process began in July, gave us enough coincidence to proceed through the fall, and culminated with the permit approval in December.

Because the bridge project also includes track construction, and the permits for the intervening right of way also include track construction, we decided to package and brand the entire thing.  This was reinforced by the desire to hold back on passenger ops until they could operate all the way down and have a safe landing.  Combine that with how fabulously this stretch will showcase the narrow gauge theory, how beautiful it is, and our rising focus on transportation to destinations (instead of just a train ride), all result in the Mountain Extension is one of the best developments our Museum has ever undertaken.  Honest to goodness I am smitten with the prospect of it.  I hope my enthusiasm for it has been apparent.

In any event, we forge ahead with 10, and then 11, as both will be vital pieces of the bigger picture we are trying to paint.  We need 10 yesterday; writing op plans for big events around 2 locomotives is difficult, due to the inability to runaround at Sheepscot while at the platform (that’s why we power swap).  And honestly- 10 does such a superior job at representing the Maine two footers than 52 (10’s easier on track too).

I believe we’re going to find the Mountain a touch un-kind to 10, and the potential utility of no 11 will become apparent.

Ok, that was too long, I suppose, but my earlier post may have come across as negative.  If so, I apologize.

See ya
Jason
