I have a Chedder Proteus plant in her,giving quite an un scale-like turn of speed at full throttle

Very nice, does it have a whistle too?.
I'd like to see some shots of the steam plant.

[muduck]

no, was buit a couple of years ago before I found a suitable whistle...the whistle I have on my Lady Barbara wouldn't sound good..it really needs a throaty foghorn...maybe electronic??
I'll do a vid of the engine running tomorrow..

[kno3]

There are some whistles with a resonating chamber to lower the picth, if that's what you are looking for. Practically they increase the whistle length, the loco guys use them.

I have a 41" long Saint Class tug that rips along at full steam with a Puffin engine / boiler.

I saw John Woodroffe at a show in Exeter once, he and Iain had some nice models they were sailing " you got that tug wiv you?" I was asked loudly, 'yes John', I was then asked loudly to let her rip, and so with 40psi showing, we did a couple of full speed runs across the pond at Crealy, "now that is a steam boat" the prospective customers were told.

You can be sure that wherever he is now, John would heartily approve of your Cruiser

Stunning tug, any chance of some photos.
I've just bought a Hemmens powered tug that looks very similar.

[muduck]

I'll have to dig through my archives...but the only ones that I have already on photobucket are these..

Thanks, very nice!

Hello Muduck,

I like your steamtug very much. 

[King]

Once again stunning tug!

How do you find the cheddar\stuart automatic gas control valve?

Thanks Charles

[muduck]

Thanks Jan.
Charles, the ABC is great, WORKED very well, until the sensor on the sight glass suffered from heat stroke.I purchased a new, very well made one from a fellow member here, but alas, it's just too close to the burner, & I can't shift the position of the sight glass...

[HS93 (RIP)]

You must, like me have the older boiler. they moved the sight glass to the other ens of the boiler for this reason , I am going to get two plugs put in mine so I can use mine again.

you could try some ceramic sheet to act as a shield.

Hi muduck
Sorry to see the sensor has failed, I worried about the positioning relative to the burner when I looked at the picture you emailed me.
Doing a bit of lateral, thinking how about moving the watergauge away from the burner. Two options come to mind the first is to make two long brass adapters threaded on one end and tapped on the other. These would screw into the boiler and the the water gauge into the tapped end. If this puts glass into a vulnerable position use two Stuart models cast elbows with stainless steel nipples to set the water gauge at right angles to the boiler, possibly using short adaptors to move it well away from from the burner tube.
If you wish me to supply thread sizes and Stuart part numbers let me know. Do you want another sensor?

Very nice, what size prop are you turning, and what make is it?

That's a shame, I've got a fairly similar burner setup so would probably have the same problem, might be something to look in to at a later date!

Thanks Charles

[muduck]

Tag, you can see the problem...I'll have to think about it, solution #1 seems ok, but I'm a builder in all things except metal




I have tried shielding, but limited space & you still want to see the water...
The prop is a 4 bladed 70mm brass number, I can't remember the make...is ideal though..prob a fluke

[benjaml1]

You could use stand off nipples to get the glass away from the burner. In fact it really doesn't need to be there. You could plumb it to a dark/ cool/ quiet space for control & have the optical glass in parallel  for scale. Few banjo unions & some pipe work & you would be good to go... Just a thought

[muduck]

Yes, I see what you mean. My problem is the lack of terminology when dealing with my supplier who is 400 miles away...I may take the boiler with me when I visit the Big Smoke, that way I don't get all those extraneous bits left over

[benjaml1]

Good luck, I'm sure you will come to some sort of resolution/solution... 

[kno3]

Before changing the location of the sight glass, how about trying some heat insulation tape on the burner side? I don't know the brand name but it is silver in colour and often used by the r/c car guys to shield the combustion engine exhaust.

[benjaml1]

Good idea, I bought some on e-bay to line the bilge area of my boat...
