   Post on Winter Blues in Avidfoxflyers General Hangar

   By MarkD, posted 13 Jan 2016

   I have been trolling the Forum lately with not much to add so I thought I would post the latest of my Avid activities.  I tried to enjoy a bit of flying a few weeks ago but with no heat in the cabin I was only good for about 30 minutes till my feet and hands got too cold to call it fun.  It is not as cold here in Western Washington as some places but on a clear day at 34 degrees and 85% humidity it seems that the chill goes right through a body. 
   So I'm gonna fix that. 
   I started building the components to add cabin heat to my Avid.  I can't put a "Muff" around the muffler so I built a smaller one for the header pipe.  It may not provide enough heat to drive me out of the cabin but should be able to take the chill out of the air.  I made a valve to divert the hot air to either the cabin or exhaust out into the engine compartment so there is always air moving through the muff and ducting and made it operate with a cable from the cabin.  All of this was sheet metal work.  It is all installed but it has been raining steadily since installation so I have not had a chance to do an OP test.
   I do not have pictures yet but I will provide some in a follow up post.
   Next I started collecting parts to build a "HACman" type mixture adjustment circuit.  I could not find anywhere a 6mm hose barb fitting for the carb tap off so I have made one in an hour or so on the lathe.  The only thing I have left to do is modify one of the carbs to tap the venturi for the low pressure port.  Maybe I can get the carb set up on the mill and do that this weekend.
   Again, no pictures yet but I will endeavor to provide some pictorial documentation soon.
   Fly safe,  Do not fly where you can't land.
