I looked back on the material data for Delrin at "Online Metals" and it said Delrin good in air maximum to 180F. A pretty close margin in engine op temps.............and brass still looks better!

......thanks gbritnell, I feel the sentiments 
and now it looks like another Webster is coming from serhat. That is a silencer over the straight pipe. Exhaust exits out of the pipe inline with a hole on top of silencer. Under the silencer there are also holes drilled in the pipe and some of the exhaust blows out and straight down exiting the underside. It is more for "eye candy" rather than a more effective way to attenuate any noise as the majority exits out the top. Would this be your first I/C engine serhat? Dave.
underside view............the silencer is made with a brass baffle pressed and epoxied to the roof of the aluminum body. Four holes in the baffle line up with holes in pipe. The silencer drops upon but is not fastened to pipe.

Thanks Dave,
Yes correct.This is my first IC engine and I am trying to apply the same exhaust system from yours. I have build several steam engines,both from castings and scrap,you may see them at

Thanks for the acolades this week! Some more "international" fans of the WEBSTER showing their stuff here too. wEc1 .....When and if you are able to, try to get videos of your engines on "You Tube" sometime. Dave. PS. I got an antique digital camera from 2002 Pete. It'll have to do!
Just a couple of add ons to the Webster since completion. An extension radiator surrounding the spark plug, a new Traxxis .15 carburetor, and a "gas powered flashlight" ......rather a generator powering one brite white LED lamp.

Nice Dave!
Very crisp clean lines. It's a beauty.

How does that carburetor work, Longboy? are you happy with it? I am soon going to have to buy one for my Webster, and I realy have no idea what to buy.--Also, what are you running for an ignition coil? I was going to use a 12 volt automobile coil and a 12 volt battery out of my boat, but what you have appears to be much smaller and more portable, and appears to run off two D cell batteries?---Brian
The Traxxis carb works well as did the O/S carb I used originally. The difference being I can set the mixture on the Traxxis with thumb & forefinger where as the O/S needed a screwdriver. Not a big deal cuzz once set should be good when using the same fuel but definitely easier to optimize a running engine with a finger knob. The coil is an Aero Spark brand model engine coil from the '50's when model airplanes had point fired sparkplugs. They are 3 volt and I use a pair of "C" cell alkalines for power. The coils come up on (where else)....EBAY regularly but not in great quantities! Wilco and Modelectric are other brands I see on Ebay and battery cases available here also. Easily transportable from engine to engine or intergrated concealed or exposed on the Webster base mounting board a couple inches longer it sure beats an auto 12V coil and a motorcycle battery. A "turn key" alternative would be the S/S Machine & Engineering complete I/C engine kit for $100 or its various components for less $$$. Roy Sholl, the proprietor, will spend time with you on the phone for your needs. You can see this system on my Breisch hit miss engine at "Longboy4" on YouTube.
