What an excellent job! Chris, this is going to be one magnificent model and the speed that you are going with it, there should be steam by Christmas :lolb:

Well, this Christmas it will be steam over the hot chocolate, next year it should be pulling the tree out of the woods!

Okay, we will let you off for this Christmas ... I guess there are still a few parts to be made.

Its amazing how fast Lombard was able to build a couple prototypes and be in production on the real thing. It will take me a bit longer!

When I have the rest of the corners rounded on the spokes (would have been today, but was out doing family stuff all day), I want to make the axles for the sprockets (that will be easy), then will start on the big plates that the track assembly is all held by. In the real thing they were big castings, mine will be built up and silver soldered together from smaller plates. I've been digging through the photos of the real one to figure it all out, and need to model it up in Fusion360. The shapes are pretty straightforward so that should be easy. The plates hold the bearings for the sprocket axles, and include a sliding tensioner adjustment, as well as guides for the roller chain at the bottom inside edge of the tracks. I am planning on building the whole thing from the ground up, so will finish the track assembly (including the roller chain), then the front skis, then on to the drive chains and differential assembly. I'm having a ball with this build so far!

Forgot to post the final pics from last evenings session, got the rest of the corners rounded on the first sprocket, few more to go on the others. I am tempted to try running them through the tumbler with the ceramic media to see if the finish comes out like the track plates did, not sure if such large parts will move properly in the bowl, but worth a try.

Great progress Chris.  :ThumbsUp:

That last picture looks like some kind of fancy pendulum for a clock.  :Lol: You'd definitely be the first one on your block to have a clock like that!  You can tell that I've been reading up on clocks lately!

I have done some very large parts(like about twice as big as the sprocket) and they work fine.

Good to know -  I will give the sprockets a run in the tumbler as soon as I finish the rounding of the spokes. Thanks!

Chris, based on how well the tracks turned out, I think the tumbling of the sprockets will have an equally pleasing result. Just my 2 cents.

Let me say this about that  (hmmm, where have we heard that before  :lolb:) I thought the tracks had that "earth hardened" look when they came out of the tumbler,  as they would on most tracked equipment and thought "man he nailed that " :ThumbsUp: :ThumbsUp:. However,  if it was me,  and it's not,  I think the the sprockets would look good with some "faux patina " , a contrast,  if you will.  But,  that's just my thinking.

Looking back at the pic of the sprockets and tracks together I think I agree with Cletus. Of course you could of made the sprockets out of 12L14...............that would of taken care of the rusty patina look!  :lolb: The "earth patina" will take care of itself on that first trip down the hill with a load of firewood!
