I needed a tongue muffler for my Ringmaster +P that I am in the process of finishing now.  It has an OS .25la on it but is still tail heavy....curse of the Ringmaster!  Anyways, a tongue muffler for this little scamp is around $25 and I don't have that kind of cash to throw around, so making what I need is usually what happens.  I started looking at the stock muffler and decided with some judiciouse hacking, filing, etc, it would make an excellent tongue muffler.  I believe this same process would work for many others as well.  As you can see this saved me 1 3/4oz.  Wished I could loose weight this quick.  It only took me about an hour.  I used my Baby band saw to rouhp cut it, my stationary sanding station to rough sand it and a file to finish it off.  The holes are 3/32" in diameter and there are 11 of them.  I figured I could always drill more if needed.  Oh yeah....the base plate is just JB Welded on.  I haven't decided yet wether to add a couple of screws or not.

No I haven't yet.  Its still winter here! LOL

aaahhhhh Steve....you crack me up!   And besides, I had already thought of that!

No I haven't yet.  Its still winter here! LOL

Surely you can take it out to your driveway and annoy the neighbors!

   I am with Clint on this one, why take off more weight at the front when the Ringmaster is tail heavy??. Apart from that, you seem to have done an excellent job at converting the OS muffler into a very nice tongue muffler! Congratulations on such modeling abilities!
   While we are on topic about tongue mufflers, why are they so popular in the US? From listening to the few I have seen this side of the pond, they either DON'T muffle (b....y loud if you ask me!) or if they do mufffle, there is so much backpressure that the engine is choked and runs with low power plus overheating! A good light tube muffler is just streets ahead IMHO.

Hallo,
   Right, if the plane is nose heavy, I am with you all the way! I still have some cigar tubes somewhere, but goodness knows where! I have not seen them in 10 years or so.
  We can get some very good Havanas in tubes, but main problem is that I cannot afford them anymore. Pension gets smaller as costs rise, syndrome. Probably a good job I can't afford the Havanas, I would probably be drummed out of the forum for Un American activities!

Regarsd,

Andrew.

I've spent the last year saving Sharpie markers from work. These have an aluminum body, and there are two different diameters to choose from. I've built one muffler, used a wood block to attach it to the engine. Never ran it ,afraid the wood might burn. Wally world has 4 markers for $7 here in Indiana.
thanks
Steve

stephen and Bill....those are both excellent ideas.  I forgot all about the old Sharpie tube muffler idea! LOL  I can get them at the dollar store for next to a dollar! LOL  And I do have a Dubro muffler extention tube that I got specifically to make tongue mufflers with.  Unfortunately it is too big for this particular application.  Its great to see and hear about others that enjoy making their own stuff as well.

Thanks for the your responce.  I was hopeing that someone that had actually used this method would respond.  What type of JB Weld did you use?  The type that is in seperate tubes and has to be mixed like epoxy, or the type thats a grey stick (like plasticine) that you mold?

HI Andrew,

You can get a tongue to breath about the same as a tube in operation.  And if you use a light muffler then you can sometimes save using any tail weight.  Don't want to get Bob Gialdini's *Bar Bell* effect.

We have found that *some* engines really need a healthy dose of back pressure to hold a good stunt run.

And you are correct, they always are louder than a good tube muffler!
