That is just too cool - very impressive.

That is just over the top Bob!  Did I miss something somewhere though.  I hear sound coming out of there.  Where and how did you mount the decoder?
I know you said earlier that you weren't sure where...

WOW...............

Mornin' all....

Thank you for the encouragement here.............  I'm working on an idea for a removable roof.

Dave......... the decoder is in the water tank, low and behind the cab.  A good friend and modeler here in town found a decoder that is surprisingly compact.  No idea who the manufacturer is.  It came out of something he was working on for yet another modeler.  The speaker is a small square and fits snugly between the rear frame rails.  I put a closed end paper tube around the back of the speaker to concentrate and direct the sound.  I have more of that screen material that I did the stack screen so that will be looking out the back of the loco under the tank. 

Having seen this turkey move now is motivational and I'm ready to get on with some other parts that I have been procrastinating about.

thanx again..............

So after some weeks (months) of procrastination............

Maxim of procrastination:  the sooner you get behind the more time you have to catch back up !

Here are some photos of the roof.  I decided to attempt to make the roof removable down to the ribs.  The front of the roof locates with pins into the front wall of the cab.  The rear are .010" brass that is shaped to the angle of the cab wall tails and hook over the tail.  By squeezing in on the roof sides they move in and release the roof panel.  It actually worked the first time............... You might be impressed but I was amazed !! ! ! !

The pins are soldered to the underside of the roof and when assembled fall over the track for the windows and go essentially unseen.

Bob,

Just fantastic and I'll add to what John said, "The most talented" as well. I consider myself better than avewrage at brass but I see now I'm just an amateur, and me as well.

...absolutely incredible!!!

I started today on the winch parts for the front of the loco.

Everything is still pretty rough and needs a lot of shaping and filing.

Bob

Here are the main stanchions with a rough bore of 1/8 through the babbit bearing material.




Another shot of the rough stanchions.




And then finally line bored to the 3/16th shaft that will be the main shaft of the winch.

After all this time and work on the Falk, you need to take a break and
find a hobby!!!

Dave ....

Good idea

Thanx
Bob

Next step.........

I made up the brackets for the upper winch shaft.  The upper is the pinion shaft and the lower is the bull shaft.  Please note that I spelled this carefully.

The bull gear runs on the lower shaft and carries the gypsy capstans (spools) and the upper shaft has the pinion gear and flywheel that runs from a small steam cylinder housed in the cab.  I've not even started on that yet.

So here are the latest.

I first made a PVC test jig for mounting the upper brackets.  It is the same size as the PVC core in the boiler.  This allows me to hang threads for mounting that the thin sheet brass wrap would not tolerate.

From the front.

[GPdemayo]

I applaud you're dedication to careful spelling.....great build also! 

[bparrish]

Ok....

I'm back at it.

Below are photos of the making up and cutting of teeth on the bull gear. 

The first photo shows the raw parts.  The iron ring in the center was cut from a iron pipe coupling and turned down from the outside and counter bored to remove the inner threads.  The disc on the right is the center of the gear and will be cut for spokes later.

The iron ring is a -.005" press fit onto the brass disc.

Next is lash up for cutting the teeth.  Shown is the indexing wheel that I use and it has a 48 step index inside.




The last two photos are of the indexed cutting of the teeth.   I don't use a gear hobber so a cutting abrasive wheel is the next best option.

Bob,
Very nice, how are you indexing the cutting?
It looks great.
