Has anyone got any experience with these?

I'm currently suffering from memory block, but there was a builder 30 or so years ago who fitted all his locos with one, operated by a wheel in the middle of the smokebox door. The claimed advantages were that it wouldn't run away downhill and had good power uphill.

I know tony sant used to use them. Considering having a play with making one to see the effects

I think you are thinking of John Turner, Brian. This topic was brought up recently else where on this forum where I wrote a lengthy description of how they work. I have one of Mr Sant's Pecketts which is fitted with an exhaust regulator which works very well but does remove all trace of and exhaust beat.

As I'm not one for being particularly bothered about how my 1/19 scale loco sounds (a 1/19 scale chuff isn't particularly loud) but am rather more bothered about the speed it runs and how it performs on gradients I found myself thinking about an exhaust regulator this afternoon. It's just an idea that I might play around with on my ragleth but I haven't decided yet

That's right Dan - thanks! I nearly bought one of his locos as my first, but the budget was tight so I ended up with a Dylan kit................

They were also another method used to tame high speed Mamod's - http://www.hglw.co.uk/Mamod%20Exhaust%20Control.pdf & http://www.hglw.co.uk/Mamod%20Exhaust%2 ... Photos.pdf

I have now made an exhaust regulator for my ragleth. Its yet to be tested on a line with big gradients but worked great in trials on my line.

I have found exhaust regulators are very effective at taming Mamods or any other oscillating cylinder locos. The design I make fits horizontally in the smokebox and uses the "smokebox dart" to adjust the amount of throttling. I have it wide open to clear the condensate at the begining of a run and then shut it right down so the loco just potters arround the track.

If you want some drawings let me know and I'll send you a pdf file
