Yes, I will run it like this for a while to ponder how to make it better. The main purpose of this one was to see if the principle works, which it does.
When the weather clears up I will do a video of it running on the tracks (probably not this weekend then).

Right, I don't mess about me... MK I made in a morning... MKII made in the afternoon.
Same exhaust pipe, new top regulator bit. I have tried to make it look like a chimney cowl.
Running on blocks...
Running on track (sorry about the quality, I was trying to keep the camera near the engine so you could hear the chuff/pop/throb the steam makes as it forces it's way out of the regulator). This is with the normal mamod regulator quite a long way open, and the exhaust regulator quite a long way closed...

Certainly has a bit more of a chuff noise!
Mk 2 looks a little better too 
What is the result then? worth doing? not worth doing?

I want to try pulling some wagons before deciding really. I am still a bit reluctant to take Authur to bits to fit one, this is on my other loco. Considering it has standard pistons I would say that it certainly seemed to still have a lot of pulling power, but I will know for sure when the weather clears up and I get some wagons out.
For the money and effort then I would say it will be worth it. The IP/PPS regulator is £23, this one was about £3 and I have enough pipe left to make another one. Also there is no modification to the loco, so if you don't like it take it off. No hole in the back of the cab to worry about. In reality it is probably as easy to make this than it is to fit the PPS regulator anyway.

May a suggest a minor mod to MKIII.
Put some marks on the ring around the top so you know how far you need to twist it to get full, half and slow throttle. |
Yep, you can tell that with this MKII version by looking to see what direction the brass cross piece is pointing. Bad soldering at the front = full power, bad soldering at the back = off.

Very nice Job Chris 
Thanks for the link to K&S metals.
Someone on here was asking about where to buy brass.
I buy that brand from our local hobby shop. And if our hobby shop has it, then just about any hobbyshop in the world should
