Crap shoot, since optimum depends on velocity of draft. I have used what looks like 1 twist per foot and been happy with results. You can always twist it more...but getting it untwisted is a bit of a headache. Suggest you cut twice as many as you need and start slow. Have a set that you can swap ou...

Any thoughts on twist per foot?

Baffle boosted avg pressure by 20 psi Was able to run whole track even our incline that all of our steamers struggle on and that was with an additional passenger.

Next up the flue inserts

long term stainless will last longer - but to prove a point.....

For a vertical, just cut strips what will fit in flues and give them a barber pole twist then bend the end over so that they will not fall out.

that is the plan steel strip then cut a lil slit at the top so i can fold it into a T shape to hold it in place.

If this helps I’ll make one out of something thicker and less halfassed

Chris, Why don't you bring it to our shop or meet us at Ridge and we can help you with your Clyshay. Jeff Smith, Florida I am going to try to be at the next big meet. Hoping to have my 0-4-0 running by then as well(Wishful thinking). I just cut out a baffle and am going to give it a shot. Also goin...

I am sure the larger sized fire tubes are not helping the case. Ill do the plate at the top and then try turbulator inserts when i get the change.

Hi, your superheater coil is far too short to be really effective. A pancake style coil with about 1/8 th of an inch space between turns virtually covering all the tubes with about 3/8 inch space between it and theinside edge of the boiler barrel would do much more, and would act as a baffle somewh...

Current setup

While turbulators may well help I reckon a better use of the heat lost would be to add a superheater. A simple pancake coil in the smokebox would catch a lot of heat and liven up the engine performance. The only downside would be that you MUST have a mechanical lubricator to ensure proper lubricati...

Happy to say the seam is now removed! I am touching up a few other seams as well on and will be rewelding.

The penetration on this seam was not good since it was a super tight fit and I did not do a V groove the first time. Lesson learned.
