RE: valve adjustment - feeler friction

I bought a second set of feeler guages (the same make but in a plastic
"holder" instead of the metal one).  Before trying out the dual method or
even the quad method :) I thought I'd just check them out with my
micrometer - I won't bore you all with all the sizes but below is the result
of just the 0.15 and 0.30 mm checks (all in mm):

Nominal       "Metal"                 "Plastic"
0.15        0.1485 (-1%)        0.1484 (-1.07%)
0.30       0.3035 (+1.17%)   0.3145 (+4.83%)

Just a matter of interest.  Needless to say, I am still using the single
feeler method :)
