To prevent the cool collar from slipping off the oil filter, I am just going 
to drill a 1/4" hole through it and through the center of the oil filter, 
and secure with a 4 inch long 1/4" diameter bolt, that will go right through 
both. (Only kidding....I will use a 3/16" diameter bolt so not as much oil 
can leak out of the hole in the filter). I will have to make sure not to 
tighten the bolt too much, or it could crush the oil filter.  That way I 
won't have to worry about it coming off and going through my prop.  Do you 
think I will have to seal the entry and exit holes in the filter with 
silicone or ?  On second thought, maybe I will just go with the clamp and 
safety wire it to the mount as Ernest suggested.  Paul Conner
