My Book
 

Top Row
Photo #1 - This just shows a brass fitting I made to accept my static-pitot lines that will come from the right strut, through the wing and into the instruments.  Yah ..... I know ...... Everyone puts them on the left wing.  Assuming they cause a slight amount of additional drag I wanted it on the right wing.
Photo #2 -Shows the cardboard profile of the wheel pant.
Photo #3 & 4 -Attached and drilled the struts after total alignment of EVERYTHING.  Now I can make the flying/landing wires.  Don Aven came over to help assemble it.  Man he has been a big help.  He brought his scales and we piled everything on it in the proper places (i.e.-Mags, generator, carb, air scoop, exhaust, eyebrows, Instrument panel).  Total weight is 636 lbs. so will be close to 750 ready to go.  My original estimate was 740 so I am a happy camper.
Photo #5 -I needed a carb heat muffler and being cheap, decided to build my own.  It appears vaguely similar to one used on Taylor Crafts.  This picture shows all of the parts.  The main idea were the pieces of 3/8" aluminum tube that act as stand-offs for the shell.  They were riveted in place. (3 on each shell) If this works as I have planned, the air will come in and be able to circulate around the exhaust stacks before exiting.  The other main plan was to be able to disassemble it if needed.  Lots of notes on this picture so click it for a larger view.

Bottom Row
Photo #1 -This is from the engine side.  The sides are of .018 galvanized steel.  As you can see, the front holes are below the "V" where the exhaust stacks are welded together so the air should circulate in this area before being drawn to the outlet hole.  In addition I have quarter inch standoff's to open the front sides.  Should provide plenty of air and is adjustable.
Photo #2 & 3 -Show the completed carb heat box.  I really wanted two of them, so I could have matching sides and use the other for cabin heat......... but this S.O.B. took the better part of 12 hours to figure out and assemble.  It isn't show quality but appears functional and it won't fall off.  Lots of angles and bends that all need to come together.
Photo #4 - Decided...... while waiting for my West Systems epoxy to arrive, that I needed a heel plate for my feet to rest on and not ultimately scuff a hole in the plywood so I created this out of .032 aluminum.  Another advantage is that my feet will always rest in the same place in relation to the rudder pedals.  Very important when attempting to apply brakes.
Photo #5 -This is the start of a cowling mold.  Wanted to get the side view outline framed up so I could check to make sure it conformed with the lines of the fuselage and it does.  Will pull it off now, wrap the engine in plastic, put it back on, check thrust lines.  I want 1.5 degrees of downthrust and 2 degrees of right thrust.  Make sure what size spinner I can get.  I want an 8 or 9 inch dia. but it appears most folks have 12's.  Anyway I need to get the spinner settled before I start packing foam around everything. Hope I don't have to settle for a 12 inch spinner.
(Note:  Dennis Robinson found my 9 inch spinner -  A/C Spruce of course.)
