Re: Homemade propeller

Thank you very much, to build its own propeller can be a very economical option. I even felt that it was easier than I had imagined to build but I still do not know if my Engine has the strength to spin it. but the advantage of steel is that I can twist and cut and weld on the propeller how much I w...

Re: Homemade propeller

I may not have the largest whistle but I have a big propeller :D I'm not so worried about cracks in the weld, so long as you don't weld to long welds and keep the temperature down during the process so the risk is minimal, it is not as welding cast iron or cast steel . the Centre is probably not ent...

Homemade propeller

I have long played with the idea to build a propeller and finally made a try. find the results where good. the only thing that was a little difficult was to twist the blades. I did it with a small hydral press . the blades were made of 15 mm steel. http://i1022.photobucket.com/albums/af345/cadillac4...

Re: Coal gasifier

the start time is around 4-5 minutes. sometimes its easy but often I have to give the Starter a extra boost with 12 volts to help suck the gas in.
but when gasifier has got up the heat. it keeps the coals glowing for hours after you turned off the engine, and you can start almost immediately .

Here you can see the superheater tubes under the boiler, if you look carefully you can see the small superheater tubes to the atomising burner in the Middle.

Re: Superheating

Yes I have, of course, an isolation valve, and I have the steam trottle before the superheater, and a bypass pipe to put there if something goes wrong. the bypass pipe has to be bolted in with flanges and is no fun to do with a hot tube, but probably more fun than to paddle a 30 ft tug
