Holding reed in with gasket cement?

Holding reed in with gasket cement?
I have an engine that has the reed valve missing. (049 of other brand) I made a reed from Mylar. Works fine by blowing/sucking. I put a dab of gasket cement on the ends to hold it in permanent.
Anyone try this? Seems like it should work. Don

Re: Holding reed in with gasket cement?
Well... the reed is supposed to be able to move freely and spin. Are you missing the reed retainer? Have you tried it in an engine yet?
Re: Holding reed in with gasket cement?
I have not tried yet. The reed got sucked into the engine but no sign of the retainer. I tried to make a retainer but it held the reed to tight. Don

It would be best to tell us which engine. Many here have experience on different brands.

Got pictures?
Some engines use a reed that is fixed solid at one end and flex in a cantilever manner. Usually there is a heavier retainer that prevents the reed from flexing too much.
Functioning in a static manner is quite different from 10,000 times a minute or more.

It is a Testers 049. I made a retainer from music wire. I have no faith in it working. Yes! 10000 rpm is diferent. Don

Re: Holding reed in with gasket cement?
Some Testors engines had a wire clip like earlier Cox engines and some has a clip-on plastic retailer like the later Cox. I don't think either of them are interchangeable. It's not hard to pick up a Testors "pipe bomb" engine with the small "fly-em" tank for a couple of $ and use it as a source of parts.
