Err ... high technical comprehension low reading comprehension ?

As mentioned in my reply to Christian, I think I am first going to try 
the blanking plate fan mount (see that message for a link to someone who 
has already tried it) but, not having a pop-rivet tool I will revert to 
my motor tool box and get out the short, stubby screws and tube of 
Loktite red.  Over torqued nuts + anaerobic sealant beats squished metal 
tubes and washers any day.

You should always clip those long tiewrap ends.  Just like you should 
always wear clean underwear when you go out.  Because you never know who 
is going to see.

... provided there is something at the other end the rubber mount can be 
glued or screwed into ...

It also allows you to more closely control the cylinder head temp for 
higher compression and allowing the use of lower octane fuel while 
improving BMEP.

With all due respect, some of us have piloted rotary wing aircraft and 
have oodles of first-hand experience in this bit.

That's because the leading edge can more easily break the sound barrier. 
 But, you knew that, right?

Cool.  I was wondering what else I could do with that spare radial 
finned alloy head from my 1959 Zundapp Super Sabre.  I wonder if Komeri 
has coarse threaded DIN spec 14mm bolts for mounting it.
