Thanks Bill, I got the chain making process down pat now, just a matter of turning the crank, as it were. The first 4 links are going to get repinned now that the dimensions are worked out, the rest are moving nicely. Probably have one full chain set every two or three days now.

One roller chain down, 3 to go!   :whoohoo:


It worked out to be 35 links per chain to be a good fit on the track frame. I was a little worried that I'd need to put in one or two slightly longer or shorter links to get a reasonable fit since there is no adjustment for length on that chain like there is on the others, but lucked out.

And as I suspected, I need to grind off the a little on the lower edge of the trim flange at the front edge (left side in the picture) of the track plates to let the chain go by unobstructed.

That came out great Chris.  :ThumbsUp:

I couldn't remember what supports the top run of the chain, so went back to page 30 and saw that it can just sag down and run along on the top of the longitudinal frame (whatever you call it).

Chris, that roller chain came out really well.

Yup - and the chain is held from sliding off horizontally both by the grooves in the inside of the track plates, by the back wall of the frame, and by the lip of the lower track frame. It just sags down against the top of the box beam (that is what I call it anyway).

Thanks Vince!  I would have liked to make the side rails from slightly thinner stock, but this was as close as I could find, it almost matches the scaled dimensions of the real one. Close enough for me!

Hi Chris, a pleasure to watch. Some day this model will make the same drving noise like the real one. A monster jangling with the chains.
Kind Regards

All sorts of noises, steam hissing, chain jangling, tracks clanking, whistle blowing.... Should be fun!

Some good progress today, the second track roller chain is done, two more to go (and then the two drive chains). The process is getting streamlined a bit, things like using the tabletop 1" belt sander to debur the drill holes on the side rails, etc is really saving time and wear/tear on the fingertips. Currently drilling, deburring, assembling, and riveting about a dozen full links in about a 45 minute session.

To paraphrase (badly) the Brit game show, "I AM the weakest link, Hello!".

Um, lets see, err, the cotter pin is on the underside in the photo. Yeah, thats it!

Actually, on the real one, they used two different setups over time, one all riveted, the other with cotter pins on every link. With the side roller chains, there was nothing to obstruct removing them out the sides, so they could be taken out without a master link. For the drive chains, there had to be a master link to remove/replace since it went around other axles.

The chains are great Chris.  And the best part is that   you are doing them and not me.
