Chapter 13, 14 back ordered items arrived. Also recieved the wing foam from Eurika.

My neighbor called me when I was at work to let me know "There are 7 BIG boxes in front of your hangar door!"    These are the CNC cut wing foam.    Also, the Aircraft Spruce back ordered items arrived.   I had the order changed from out of stock Cleveland master cylinders ($500) to Matco MC4's (~$200).    I've been working on the shop and equipment.    Photos coming soon...I promise!

Chapter 3 - 10 x 16 practice lay up.

6 plys of 12 1/2" x 18" BID

After curing, trimmed to 10" x 16".   Weight should be between 10.5 and 12.5 oz.  9.35 is pretty good!   No flaws indicating not enough epoxy was used.

Oct. 7th 2014 update

Ordered Chapter 13 Nose Gear hardware from Aircraft Spruce today.   Also submitted builder registration transfer for plans 1675.  Submitted the release form for the purchase of the Eureka wing core foam.

Received a new cutting mat and scale today.   I've got two scales now, one will read up to 5 .lbs and the smaller only up to 100 g.    Both are handy because the smaller one is more accurate for small quantities and the larger one can measure bigger objects that the little one can't.

Checked the epoxy pump (meters by volume) by pumping hardener and epoxy into separate containers.   The proper weight ratio is 100:40 versus the volume ratio is 100:50 for the MGS epoxy 235.   The weight was pretty close.  

Chapter 3 practice lay up is curing now.   It was a little warmer in the shop tonight and the wind was blowing through hard enough that the 12.5 x 18 fiberglass squares wanted to flop around a little when trying to line them up.   I'm anxious to see what the weight is going to be.   I wear cotton glove liners and powder free 6 mil nitril gloves.   They're heavy enough to reuse several times.

Scheduled some flight time on Friday at KFTW with a new FBO.   I need to stay current and get checked out in another rental plane.    One of the C172's I rent at another is down for maintenance.  The one I got instruction in keeps pretty busy so its nice to have options.

Jump start on buildilng a Cozy Mk IV

I purchased Sean Sullivan's Cozy Mk IV project on September 19th 2014.    He'd bought a flying plane and found he'd been spending little time on his project.    Incidentally, I'd just purchased another set of plans so those will be set aside for awhile.

Sean is local and it only took me about 30 minutes to take a 16' trailer down, load the tub with wheels, canard, wheel pants, epoxy pump, fiberglass, DO pedals.   The canopy is currently a one-piece that includes the turtle back and carbon fiber top engine cowl.   The leg fairings are also on.

It took a few weeks to continue getting my hangar ready for this project.    3 Paulk workbenches have been built.   Several 6 lamp T5HO lamp fixtures are mounted above two of the workbenches.

Tonight (10/6/2014) I ordered:
 Jack Wilhelmenson's retractable nose gear ML1-12EHP, Castering nose gear assembly, EZ-RL Rotary Canopy Latch and the TQ-1 Three Lever Throttle Quadrant.

Aircraft Spruce's Chapter 14 material with fresh MGS Epoxy and hardener.

Eureka CNC cut wing foam cores from Stephan James.

Sunday night the center spar jig was laser leveled on two work benches butted together and the work lights mounted.  The epoxy pump was cleaned and o-rings replaced.   Old epoxy was used to glue scrap plywood together to be used for blocks and weights.

Most of the tools have been acquired but still need a 14" band saw and some smaller odds and ends.
A fiberglass cutting station and a wood cart for scraps remain on the need to build list.

Currently the evening temperature in the shop has been right at 75.    A few practice lay ups have been done to successfully  fix a few small non-aircraft items.

I'll start posting photos soon.
