What is the best way to mount strap on mufflers?

[Paul Taylor]

I got some new tongue mufflers. One for Ole Yeller’s Fox .35 and one for Propbuster’s (aka Ryan) Flite Streak with a K&B .35.
The instructions said to get a hose clamp, cut it in half. Screw it to the sides of the muffler then clamp it to the head. Sounded simple enough.
I stopped by the parts store to get a small hose clamp. The small size clamps would not fit around the engine. The size that would fit was very large, and the slits in the clamp for the worm screw looked like they would not hold up very long with a screw hole in them. And the big screw to run the clamp looked very large and heavy.

So my question: Is there a better way to mount these new light weight tongue mufflers?
A picture would be nice too

For the Fox 35 check with Marvin Denny.  He has a source for a REALLY neat bracket that goes around the back of the Fox so that the pressure bears on the exhaust stack instead of the case.  It works beautifully on the older Foxes.  The piece is CNC aluminum and is not expensive.

Here's pictures of the strap and muffler that James Lee is referring to.

You can sometimes use 2 small hose clamps, open the both all the way - then bend open the small tabs that hold the worm screw / bracket assembly on one.
This will leave you with a peice you screw into the complete clamp assy, and the other end will be solid so you can drill a hole for the screw in it. One end will still require that you drill a hole in the slotted area, but using a washer will help reinforce the area and spread the force across a wider area.
When flying make it a part of your pre-flight to check and make sure the muffler is still secure. Another tip I had passed on to me is to tighten the clamp a bit at a time and keep turning the engine over to make sure you don't overtighten and introduce any binding in the piston / cylinder fit.

Paul,

I have one of those mufflers for the Fox 35 if you want it.  Just like the one in the picture.  I really nice man from Kansas had them in Dallas.  Word has it he will be in Memphis in September!!!

These can be made from metal straps too. This was made from stainless.

Well it is not real pretty but you know the cover plates that are on the back of your PC to cover up the slots for cards?
 
I took two of them and cut strips from them about 1/4 inch wide.

So far so good.

  Gentlemen (?) I really hate to disappoint you, as I really intended to make that contest. I already had my motel reservations.  But due to serious circumstances  FAR beyond my control, I must be in Savannah GA  soon for approximately 3 to 4 weeks and will miss the memphis AND the Tulsa contest.
  One of my sons (#2) is having cancer surgury on the 12th of Sept and I should be there to help out.  He lives alone and will need assistance and his girlfriend lives in Florida and cannot get off her job  except on  weekends.  So there is another good time shot to h***.
  Rootbeard, I would recommend the strap and muffler shown in the picture over the similar thin strap due to the strap having a tendency to tilt to the sides when tightened down.  They will work however (the thin straps ).  Scott Riese has similar straps that fit the K&B green Head Torps and McCoy red heds and they screw into the muffler with one screw from either the eront or back side and one screw from the bypass side.  I highlr recommend both for their design applications.

Who has tube mufflers for the Veco .19 series 100?

This is what I did to adapt a muffler.

This is one commercial muffler.

This is another commercial muffler. Note that they both started with the exact same clamp.

Hey Marvin; Really sorry to hear this. We will be thinking of you guys, and hope and pray that everything goes well. When it rains it pours doesn't it. Doggonit
