The cowl will be pretty light. The final parts should weigh in at just over a pound.
|graphite backing plate|
This is the graphite spinner backing plate. although I only used 3 ply's of 7 oz graphite, it is half the weight of the 7 ply fiberglass mock up, yet it is at least 10 times stiffer. I will wet sand the resin line that is visible. this is the joint between the two mold half's. I will chuck this part in my lathe in the 3 jaw chuck to register the center, This will be a check to see if I located the center true enough in the mold.
On another unrelated note, I am now back in Design at my company Triumph/Vought. I am working on a manned/unmanned program based on the Berkut Home built. We are designing a larger version. I had the pleasure last week of meeting Dave Ronnenberg, the designer and builder of the Berkut. I was invited late this week to come out to Santa Monica and fly the Berkut by Dave. I'm sure we will also talk about some structural issues!!!I leave tomorrow morning for Santa Monica via San Diego. My friend Mike and Neal La France are going to pick me up at the Santa Monica airport in a Luscombe Sedan and fly us back to Gillespie field in San Diego. Neal and Mike are old friends from my early Wichita days. its been years since I have seen them.
