Re: Question re wick burners vs chick feed types.
- Hi Frank, I have never tried square tubing mostly because it is really expensive here. I think it might be hard to bend and I don't know if it would have any advantage over round tube. I did see Richard's photos before. Certainly a horseshoe shape is easy to build. The difficulty with engines without boilers is that they are quite fussy about maintaining the correct temperature if you want max. power but OK if you are happy with just running.Could be better than India diaphragms. My coffee maker engine is a horseshoe design. So now answer my question.

> Have you experimented with any engines made of square tubing, which apparently does not have to be coiled as round tubing does? In the photos section there is a picture of Richard Jenkins's wooden "Popflea" with a square tube engine shaped like a horse shoe. Richard has also posted a PDF with sketches of multiple square tube engines in our files section. One advantage of such engines is that they do not require soldering or brazing and would probably be more powerful than most of the diaphragm type engines manufactured by the Indian company, Rattandeep Enterprise.
