Re: Monotube Javelin

Fred, Thanks for all the info! 4. A large fraction of liquid water provides protection of the coil from overheating, which is often the downfall of monotube steam generators. This is because the heat transfer coefficient of boiling water far far exceeds the rather low heat transfer coefficient of su...

Re: Stainless steel tubes

The retarders are laser cut by a local shop and measure .050 smaller than the i.d. of the tubes. When new retarders are manually twisted. they seldom stay straight lengthwise, so when installed in the tubes they quite often scrape the tube wall on one side or the other for most of their length. May...

Re: Stainless steel tubes

Takes about five minutes to do the whole set. Your mileage may vary. It takes me 1-2 hrs and you have to watch the soot because it goes everywhere and my boiler is so tall I need a step ladder and even with the step ladder it is still extremely awkward. In maybe 10 years I am considering commission...

Re: Stainless steel tubes

The race analagy has me wondering.. I the closest place I have been able to locate that sells boiler tubing is a three hour drive, but I can get schedule pipe fairly locally. How bad of a hit would using 1" schedule 40 pipe be on heat transfer in the overall scheme of things. I intend to tig the tu...

Re: Dynamo/Gen Set

Nice Sirius.

I always wondered how close a Stuart Sirius is to the gensets Stuart made for WW2.

I used a Stuart 4a and could get 100Watts out without much trouble with a WindBlue permanent magnet alternator. Load: 12V 100Watt incandescent light bulb.

Re: 1901 Conrad steamer

.. roll four wheels under something and it's ''cue the jerks''... As long as it's in the right forum for it I don't see any problem with it. Some people like me even use steam automobile engines in steamboats. My first impression of your photos was something along the lines of, "Beautiful work, my ...

Re: engine bit's missing

I have searched the Internet and there seems to be very little information on steam boats in any detail i.e someone showing what all the bits are and what they do so there's going to be a good few questions on here 😆😁 No problem sir, you have come to the right place for answers. As far as your feed...
