<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></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>
