I'm not suggesting that it is empty, just that a smaller volume will cool more quickly

Was the dubious bottle low in gas compared to last year's one ?
-
I agree about propane v butane but cooling seems to satisfy the symptoms. It's not the outside temperature that counts, it's how fast and how long the gas boils and how well insulated the bottle is. With butane, at scout camp, I have had to shake and warm the bottle even on a relatively mild evening. I have just looked up the boiling point of propane, which is -42C, so a bit of a stretch, but can be easily checked by shaking the bottle.
-
You said it was a very cold night. As the liquid propane boils off, for you to use as gas, it cools the rest of the bottle. It could be that you are cooling the bottle so low that there is insufficient gas pressure to drive your stove. Probably the top of the liquid cools most, so shaking the bottle will increase the surface temperature and the gas will flow again. Overnight the temperature will have equalised naturally.

I managed mine with a slimmed down 13mm open ended spanner. Worked well in reducing smoke. You need to move it in the opposite direction to its rotation, which is in the same direction as the engine rotation.

Bit late joining this discussion but I fitted all 8 seals to my Calcutt Turkish 1.8 and an exhaust valve seized in its guide after about a quarter of a mile on its first test run. I think inlet only is correct. I hate to tempt fate but it has run for 12 years since. i also found that British rings do not fit the German pistons, used in the Turkish engines, Fortunately you seem to be passed this stage.

long piping after water tank before pump

Ours is the same layout as this (apart from the bed location), also no trouble. -
Shower tray - is it possible to build one?
Speedwell replied to rubblequeen's topic in Boat Building & Maintenance
We had one made by a local plastic moulding company (Near Blackpool) who made a mould from the old one. A different company tried to make one from a drawing but the end product bore little resemblance to the drawing and I wouldn't pay for it. Arthur -
Hopefully this will be a picture of us at Fotheringhay to prove that we got there. Arthur https://plus.google.com/photos/105499103977382287553/albums/6064067767073519457 Sadly only works as a link

We have reached Northampton. Setting out on the Nene tomorrow. Please give us a wave if you see us. Arthur

Phil Speight's carnauba wax polish is by far the best that I have ever used. Expensive but well worth it Arthur
-
I broke one a few months ago and got a spare from AMC diesel at Longton, phone 01772 613003. They used to build the BMC engines there and own the Thornycroft name. They are usually very helpful. The screws are incredibly expensive for such a little thing, presumably because of their rarity value. Arthur

If you Google "british standard colours" you can get a lot of info and BS numbers for paint colours. Craftmaster can mix to any standard colour, as can other paint companies. Here is an example website. http://www.e-paint.co.uk/BS381%20Colourchart.asp Arthur

Thank you all for the extra infromation Arthur
-
I have been checking the river on OS maps and see that the chanel is very complicated and the canal maps do not show it very clearly. Is the chanel clearly marked with signs ? Also, how safe is mooring in Wellingborough ? Any guidance greatly appreciated. Arthur
-
Thank you all for that helpful information. I hope we can make it in the summer. Arthur
-
I'm sorry to have to comment but this is virtually all wrong. V=I x R Rearranging I= V/R Power = V x I Substituting for I we get Power = V x V/R or V2/R (V = Voltage, I = Current, R = Resistance)
-
We're thinking of heading to Northampton and hopefully the river Nene for our summer cruise. Can anybody give me guidance of safe overnight moorings in the area please ? Arthur

Shouldn't the rocker box breather be fed back to the inlet manifold or is this only the 1.8 ?
-
CO2 is indeed a heavy gas - same density as propane, but , as has been said, it's CO that is poison and that is about the same density as air.
-
I am intrigued as to what makes a CO alarm unsuitable for a boat. Arthur
-
"Metacentre" was a new term to me so I've just Googled it. Really good article in Wikipedia. Arthur
-
I don't think we ever got an answer to this question. If I recall correctly, boats with low centre of gravity roll easily and recover quickly. Boats with high centre of gravity resist rolling but are slow to recover. Arthur

BMC Thornycroft 1500 starting (& now smoking) issues!!
Speedwell replied to silverbuttocks's topic in BMC
Mine was an original British one, marinised by J. G. Meakes. I wasn't suggesting the throttle setting was necessarily the answer but worth a free try, if not already tried. Arthur
