<DIV><FONT face=Arial size=2>Find a bet that is bigger than the isolator in all
direction. Mine was for the blade drive on a riding mower. I cut the
pieces to the original dimentions using a scroll saw. The I drilled the
holes in the rubber with a small drill bit and worked my way up to the right
size. It takes SEVERAL times drilling with the correct size drill bit to
actually open the hole properly. The rubber will keep trying to strech
instead of letting the bit drill cleanly. Then, mount as usual. I
have used these home made isolator for about 20 flights with no sign of
wear. Until that time they were cracking or turning into gummy bears
about 1 a day, so every 4 days of flying required all 4 isolators to be
replaced. </FONT></DIV>

<DIV><FONT face=Arial size=2>Strangly I never had this problem about 10 years
ago. I do not know if they changed the rubber they were made from, but the
new rubber does not last like the old rubber did. Also the ones for World
Engines brand mounts work but are VERY hard and stiff. They shook the
plane terribly and had to be removed after 2 flights. </FONT></DIV>

<DIV><FONT face=Arial size=2>I had the same thing happen. Even a new
set just purchased did the same thing. I ended up making my own out of
a belt for a riding mower. The belt was $10 and you could probably
make about 100 isolators out of it. The good thing is it is designed
to take the heat and be break resistant. The cloth molded into it
makes it almost impossible to tear. Just make sure you cut the piece
to shape and drill the holes accurately. I used the home made
isolators at the Triple Tree contest this year. Give it a try.
It seemed to have the damping as the priginal isolators.</FONT></DIV>

<DIV><FONT face="MS Serif" size=2>Has anyone had the rubber for these
mounts soften and melt. This is the second time in the last year it
happened.The mounts are MK using Dave Brown VibaDamp 4/C
Isolators.</FONT></DIV>
