Rik, I believe that the smaller worm is the solution, but I do not believe anybody has mentioned what the issue (apologies if you have and I have missed it), I think this is all to with "moments around a point".
The centre of the motor spindle is the fulcrum, and the motor provides the power which is a constant (assuming constant voltage input) the the further you move from the fulcrum, less load is required to equal the power output, ergo the larger the worm the less power drive you have.

That's exactly my thinking though as a former primary school teacher my explanations are far less eloquent. I was out on a walk with a mate (a former physics teacher) yesterday and I found the easiest way to explain it was to use my walking pole like a propeller. Much more effort was required to rotate it when my other hand was stopping it further away from the handle and much less effort when the resistance was closer to the handle.
My mate agreed with my practical demonstration and then explained it all with moments.....

That is a blooming brilliant build Rik. You have mastered the art of this 3d printing stuff. Yes it is easy enough and the more you work on it, the easier it gets I have found, but I am still a marathon away from doing anything as brilliant as yours.

PS I was looking for another emoji to say how brilliant it is, but it seems to have disappeared....

Edit - apologies, this post adds nothing to the thread, but Philip's comment made me laugh out loud!

I think I've cracked it!!
Only took me three months!

Fantastic Rik..Well done, she doe's indeed run very smoothly now. I didn't notice any slipping at all, what a fantastic feeling you must have had when you saw her running and pulling all those wagons.
I agree also about having to redesign stuff with 3d builds, I am always doing it.....

Looks fine to me, Rik.
Very satisfying when you get to this stage.

Re: Lyn >> Schull & Skibbereen Erin(ish)
Thanks chaps. She still needs to be tidied up a bit and some of the detailing installed ( eg the outside frames) but I'm pleased with how she now performs. You'll also notice the chuff synch now needs re-adjustment but she's now much more controllable at slow speeds.

An A+ for perseverance Rik. You must be very happy to see it dragging all those wagons.
And a most interesting video too.

I really enjoyed watching the video, your railway is beautiful.
It's fun for me to see Skibbereen mentioned as that is where I live.

A lovely part of the world and definitely on my list of go to locations once this Covid business is over
