And a quick double-check that all the sizes are good, and an inspiration to myself to get them done, assembled the first length of the drive chain...

Because of Chris? Or his elves? One begins to wonder who's doing the work.  :thinking:
Mint chocolate chip cookies are a powerful bribe.

They sure are! NASA put a trail of them into the capsule to get the astronauts in...

Hi Chris,
 Think the elves need to go on a diet! Too many cookies & progress slows!

Keep them lean & mean!  :Lol:

Looking Good!

Cheers Kerrin
Get excited and make something!

Sure. YOU deal with a hungry pack of annoyed shop elves! That is how they turn back in to shop gnomes and start hiding your tools!

And one drive chain done! I did not rivet in the final pin, in case I need to add a link or two once the sprockets are in place. It should be the right number now, but thats when Murphy comes a callin'...

One more drive chain to go...

Beautiful Chris.  If I tried to do that it would be Groundhog day 2018 before I got one done.

And both chains are done!   :whoohoo:

I took them up to the belt sander to ease the sharp corners on the links, looks a little better, and also cured a couple of sticky spots.

Now back to the lathe, started turning down the blank for the small end drive sprockets...

After shaping the hub side of the smaller sprockets and parting them off, turned them around in the chuck to face them to thickness and taper the second side to match the first, so that the chains will self center.

and then over to the rotary table on the mill to plunge cut the bottom arc of each tooth,

and then offset the table 20 degrees and .475" to cut the shoulders on one side,

and then the same angle/distance the other side of zero to cut the other side of the shoulders

leaving the finished sprockets (just needed a little filing to remove the burs on some of the edges).

Next up are the back sprockets, which are 20 teeth each. For those, I think I am going to start with some flat bar for the sprocket disc, and silver solder on a hub, rather than starting with a big chunk of 2-1/4" bar stock and turn most of it away. Either way will work, this way gets me more silver soldering practice.
