Fuel bowls?

[fishy-steve]

Hi all,
My next engine is going to be a 2cc compression ignition engine. The plans show the use of a fuel bowl but no datails.
So where do you engine builders get these bowls from?
Thanks,
Steve.

Depending on the diameter required, how about the bottom end of a test tube?

For a translucent tank fitted to the engine see Here http://modelenginenews.org/weaver/Weaver_pg7.html

The pictures can be viewed at a larger size by clicking on them, whatever tank you use you will probably have to make them.

What ever you use to make the bowl, be sure to test the material to be sure it is resistant to the fuel. Ether softens many plastics. Drop a small piece of the material in a covered jar with a splash of fuel for a few days.

In the early days, many spark ignition engines had fuel bowls of make of celluloid which worked well with gasoline. When glow plugs became available in the late 1940's, a lot of people just popped in a glow plug and filled the tank with glow fuel and soon discovered that the nitro in the glow fuel turned the bowl to goo.

I was unsure if they could be purchased or if I had to improvise.
Improvisation it is!

Thanks for the suggestions guys.

One possible source is the bowls from old airline lubricators or filters. The ones commonly seen on large machinery are outsized for a model but small pneumatic components for instrumentation exist. It might even be worth buying such new. Id try searching for small or instrumentation grade air line filters to see if something usable pops up.

Another possibility is the glassware or plastic bottle industry that supplies to the medical world. You can find all sorts of really small vials and jars, often with screw on lids.

Also consider model paints and the jars they come in.

A walk through Hobby Lobby might turn up something too. There are many sections in these stores with possibilities.

Nail polish bottles would make a unique bowl.

This idea came to mind last night after leaving the site, in any event is will through this out: Shot Glasses! The idea is the result of seeing my shot glass collection and the variety seen there. They come in a variety of sizes and shapes but most of them adaptable fairly easily to a custom bowl holder. Depending upon engine scale they might be too big in diameter.

In any event i usually pick up a glass or two when traveling for work or pleasure especially if it is some place i haven't been before. They are a cheap way to buy something to remember a place by. If you find one with a logo to complement the engine all the better. Just make sure the logo is painted on and not a decal.
