 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

This sounds great.  Lets fill a canister and blow exhaust through it.

Let

the exhaust wonder around and over the small noodles.  Harbor Freight

has

tip ends that have settable orifices for tuning $16 each.  Lets fill the
last 8-10 inches of the pipe and put these ends onto the pipe.

I have used different ceramic products for both canister filters and wet dry
filters. I don't think these ceramic filter nodules will take the vibration.
I used to find broken ones in my filter and the water pressure was very low.
I have also crushed them by packing the filter too tight. I would like to
watch but I suspect that you would have hot ceramic chunks mixed with dust
flying out the exhaust.
