Includes many small sessions (1-1/2 - 2-1/2 hours) with many set-ups and clean-ups included. Thanks for your work with Cozy homepage, etc. !!!

For me, keeping track of hours was demotivating. Building an airplane is for fun. I too keep track in years. 3 years plus, hope to fly before year 4 begins. Paul Krasa Long Ez 214LP Project status: Ran the engine for the first time two weekends ago, and it runs great for an engine that was pickled for over ten years. :) Every sump drain is weeping fuel, so I have to defuel. Will continue hooking up engine gages, and start taxi testing soon. :) Ahhhh maybe, just maybe, I will fly to sun n fun 98.

Al wicks programme works real well, at one time my progress was slow and my estimated completion time went to 2100....:-) so we got on with it... Time is split in Study, Productive and other. STUDY means just that. Other is making benches,tools,cleaning all with some meaning. Productive is my time + help time received from others = Total productive. Visiting hours and internet times are not included anywhere. STUDY OTHER PRODUCTIVE CH 04 18:30 45:00 39:00+12:30=51:30 CH 05 6:15 18:30 49:30+18:30=68:00 CH 06 17:30 26:30 65:30+30:00=95:30 CH 07 13:45 34:30 96:15+26:30=122:75 CH 08 4:30 52:00 28:15+ 1:30=29:75 Totals 60:30 176:30 278:30+89:00=367:30 which works out to: 10% Study, 29%Other, 61% Productive (46% self, 15%help) At this point... Thanks Marc Zeitlin for the wonderful communication opportunity. Thanks Jean for all your help. Thanks to all contributers to the forum...you all taught me a lot and saved us time by showing where to be carefull...so that we could invent our own mistakes :-) Chris Cozy #219 From: guy.terren@dl20.laposte.telepost.fr Date: Sun, 23 Nov 97 12:03:37 +0000 Subject: COZY: Centerspar --openmail-part-000ce8f1-00000001 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Can anyone give me the weight of a finished centerspar for a mark IV?

Here are some number published in Nat's newsletter #50 on my project. Item Wt Center Section Spar 48 Fuselage on Gear 242 (no canopy or strakes)=09 Canard/Elevators 33 Right Wing/Winglet/Aileron 69 Left Wing/Winglet/Aileron 68 Turtle Deck w/Glass 12 Total to date 472 I have since painted, balanced and weighed the elevators: Left elevator =3D 14=B0 nose down @ 3.8 # Right elevator =3D 20=B0 nose down @ 3.7# Incidently, there isn't much specification on the elevators in the plan except they should balance nose down. But when you get into the Flight Handbook and read about the first flight, you will find much more detail on how the elevators should spec out. This information should be in the plan up front. These little flappers are probably the most important items on the airplane, and we must give them there do attention. dd Date: Fri, 5 Dec 1997 08:03:05 -0600 (CST) From: Tom Brusehaver Subject: Re: COZY: part weights Following bil kleb and others, here are my parts weights through CH 4. ------------------------------------------------------------------------- part weight seatback bulkhead 5lb 2oz instrument panel bulkhead 4lb 3oz f28 bulkhead 8oz f22 bulkhead (w/tabs) 2lb 6oz forward landing gear bulkhead (lower) 1lb 6oz forward landing gear bulkhead (upper) 12oz aft landing gear bulkhead 2lb 11oz firewall (lower) 3lb 7oz firewall (middles) n.a. firewall (upper) 2lb 13oz Suddenly I think my scale must be a little light.

From: Greg and Jill Hilliard Subject: COZY: part weights Date: Fri, 5 Dec 1997 20:57:38 -0600 Hi all, Just finished chapter 4. Weighing my parts on a super-duper = fancy-schmancy and certified scale at work, I came up with the following = numbers: seatback bulkhead 4.412 instrument panel bulkhead 3.936 f28 bulkhead 0.571 f22 bulkhead (w/tabs) 2.173 forward landing gear bulkhead (lower) 1.245 forward landing gear bulkhead (upper) 0.699 aft landing gear bulkhead 2.439 firewall (lower) 2.657 firewall (middles) 0.608 firewall (upper) 3.173 These parts were vacuum bagged, which has to be what explains their low = weight. I was worried at first that these parts might be too light, but = they have absolutely no air bubbles, show no voids at all and can't be = peeled off the core without pulling core material off first. Besides, I = bagged these at 5psi, not really enough to squeeze out too much epoxy, = at least from what I've read about the subject. Bagging, at least so far, has been pretty easy and pretty cheap. It = seems to have saved some pretty significant weight, too. Also, the = surface of the part takes on the weave of the peel-ply, which is much = finer than the weave of normally cured glass. Should take less filler on = the exterior surfaces when finishing. I can't profess to be an expert on the subject, I'm just excited about = what I've seen so far on my cozy.=20 Greg Hilliard Cozy mk4 #456 gjhilliard@idcnet.com p.s. marc-move me on to chapter 5!
