When I fit my cowling I had the spinner mounted and was extremely diligent in maintaining the plans stated 1/8" space between spinner bulkhead and cowling. However it's now apparent that I probably should have had the spinner actually installed because the shiny spinner from Hartzell actually comes back maybe another 1/16" or so. Put that I mounted my cowl a bit lower to accommodate engine drop and it's apparent I have a clearance issue.
The solution is going to be to sand about 1/8" off the front of the cowl to accommodate extra spacing. I'm going to shoot for 1/4" clearance between the spinner and front face of the cowling. I would imagine taking 1/8" of material off the front will either eat up all the material in places or at least severely weaken it. My thought is to buildup the inside and about 1/4" up the inside radius's with cloth and resin.
What is the best cloth type to build thickness but not lose strength? Is E glass still fine or do I need to use S glass, or something else?
Thanks,
