Fine Control for Roundhouse

[Chris Bird]

Hi folks
After the success with the test on the Accucraft regulator yesterday, I tried the version for the Roundhouse manual regulator today on my Katie. The thing is that my Katie is radio controlled, but as I switched back to the manual type regulator a couple of years ago, it was a direct replacement and was fitted in about a minute.

You can read a brief account here:  https://sites.google.com/a/gardenrailwayclub.com/club/roundhouse---fine-control-steam-valve

And I have just spotted that The Train Department has listed them on Ebay under No. 181274656497

And for those not familiar with the Roundhouse regulators here is a photo. The R/C one on the left, the standard manual in the middle and the fine control one referred to on the right.

Cheers
Chris

I believe Roundhouse tend to use Imperial sizes.
This is not a tablet of stone!

thanx rob, i can see some of the connections on the diagrams are M.E. threads so you are probably correct. its one size i have never used before as i use 2BA for my regulators. ...martin
