I can't seem to figure out how the lead screw attaches to the gear. There are holes in the drive gear but only a keyway in the lead screw. No keyway in the drive gear.
 
This video shows the direction change box and the part that the drive gear attaches to being assembled.



This one shows the drive gear being installed



I assume your lathe does not have a quick change gear box like mine does ( not many do). So your drive gear is different than mine. Photos will help. Are you certain you have the correct gear? How it attaches should be self evident if you have all the correct parts.

The miniature steam has always interested me but my skill level needs to get better before I tackle something like that.
Not really--doing small models improves your skills very rapidly--believe me, it's true. the major thing you need to know is how to NOT hurt yourself or someone else. Read up on safety--there is a discussion on this forum about that--good to read with lots of horrifying (or laughable) incidents. The guys here will help you with any problem--beginner or advanced. And since we live so close together, I expect you will invite me over when I have a chance to come to Tri-cities.
 
LJ, i strongly recommend having a look at Elmer's model steam engine plans.

I made two of them when i was starting out and learned a lot! The engines look great, very forgiving on tolerances and, with enough air/steam, will mostly run. My first (Elmer 25 wobbler) was terrible looking back but put a huge smile on my face even though it needed 100PSI air line to run at all!

I intend tomake some of Elmer's engines when I finish what I have but that comes after I get my mill together and running.
 
Greetings, all! I'm new here and reside in Western Washington. My primary interest is in foundry work, although I am also a retired machinist/toolmaker. I hope to learn from you folks, and would like to try to be helpful for others.

I made mine without a mill (just the drill press). A mill definitely makes it easier but not essential.
