   Have you looked at UL?  They look promising, but are rather pricey.

   Looks fantastic!  The neighbors are going to hate you when the horrible thunderstorm comes and dumps 5 inches of rain in 2 hours.  You know it is going to happen!

   Drag reduction

   I ran across this again and couldn't remember if I'd ever posted it before.  Very eye opening!

   Hmm, not sure what it's for, the current Taildragger version 66" wide, the nose gear is 62" wide, this is right in the middle.  Probably for a taildragger, I see the height measurement now.  Current taildragger is 22 1/4" , nose gear is only 16 1/4"
   I'd be interested, but I haven't decided if I'm changing mine from TailDragger to Nose gear when I rebuild it.  I have the front section that has the nose gear attachment, but I'd have to cut off the old one and have the new one welded on.

   Worried about a roof in winter?? Not familiar with that.  Summer on the other hand...

   That'll buff right out... 
   The airplane looks so sad, it's pitiful.

   I go most every year, but wasn't planning to go before all this, and certainly wouldn't go now.  I don't play Russian Roulette on purpose either.  (every day is a really a game of Russian Roulette, we just pretend it isn't).
   While I tend to agree that the virus isn't as dangerous as was originally feared, we also don't need it hanging around recurring every year, and learning how to be that dangerous.

    Translation for us 'mericans'
    Sub er avid hello,
    Well done for your initiative to mount leading edge spouts on an avid. I did it myself on my two speedwinds
    and that changes the performance a lot and especially the stall speed (32/35 and parachutal descent)
    friendly your

    marksires added a post in a topic Making a copy of a cowling    27 April

    With the shape of that cowl, I think I'd rather make a mold from the inside rather than the outside.  Doing layups on the inside of the mold will be challenging, and removing the mold, unless you plan a one-off and destroy the mold, would be easier.  Plus, the inside dimension to mate with the lower cowl is more likely to be correct.
    Pour foam is decent for a one-off mold.  For long term use, not so much since it continues to cure and expand for quite a while after the initial 'cure'.  Use thin plastic, like really cheap paint drop clothes, inside the cowling, pour the foam in.  Let it cure, then it looks like you should be able to slide the old cowl off by pulling the mold back toward the 'cockpit'.  Tape up the mold with packing tape (although that shrink looks pretty good to), put some mold release on that, then lay up the new cowl over it.  Just don't wait too long before using the mold, as mentioned, pour foam continues to cure and expand over time.

    Whatever you do, don't put any rye grass on it.  It grows in clumps and will make it very rough.

    I generally load any pictures I want to post in to Microsoft paint first, resize it, usually to 30%, then save the smaller file as whatever it was with _small on the end (before the period).  The small size posts much better.
