 Since the rotary loves to eat the innards our of mufflers (and the
muffler too), I was thinking of an alternative material to pack my
muffler with. (Here's the wierd part) I have an Eheim (sp) aquarium
filter that uses a ceramic medium that just may make a good packing
material. (I warned you.) The ceramic pieces are about 1/2" X 1"
with approx. 1/4" holes running lengthwise. They sorta look like
noodles, only made of ceramic and should be available from any
tropical fish store. Would ceramic make a
good packing material? Can it handle the temps of the rotary?(snip...)

I stopped by PetsMart and bought a box of ceramic noodles for 8.99, weighed about 1#.  Depending on the size of the muffler, I imagine it would take at least 4-5 boxes.  At home I put my oxy-acetylene torch to one piece and got it glowing red hot and held it there for about 5 minutes, but I couldn't melt it.  They may be a little weighty, but it looks like they can take the heat.  I was thinking that the aquarium stores may throw these away when they clean their tanks and be willing to give the old ones to anyone who asks.  Hope this helps.  If anyone's interested I can snap a picture with my digital camera and send it to Paul. ---Mark

Sounds like it is worth a try.
