on the airframe and the propeller spinner available for fitting. Do 

not proceed further until that has been accomplished. 

.....

Previously, you fabricated two cowling mounting flanges, one for 

the top cowling half and one for the bottom cowling half. Locate 

these two flanges. 

.....

It will be necessary to cut a hole in the nose of the cowling 

for the crankshaft to pass through, The hole should clear the 

crankshaft by only 1/4" to minimize air leakage. 

.....

The fitting of the cowling is a trial and error operation. By 

fitting the spinner to the crankshaft flange, you can determine the 

necessary cowling length to allow only a 1/16" gap between cowling 

and spinner. Obviously, the cowling is trimmed as necessary on the 

aft face. Once the length has been arrived at, it is necessary to 

mount the cowling mounting flanges using BSP46 rivets on about a 3.5" 

spacing. The flanges are located so that the cowling will fit flush 

with the fuselage after mounting. The rivets holding the flanges also 

serve to mount the fiberfrax and aluminum sheet to the firewall. 

.....

Some trimming of the junction of the two cowling halves may be 

necessary to achieve a best fit.
