Chapter 8, Step 1, paragraph one says to glass the inside surfaces with 1 BID, then assemble the headrests. I suppose it could be clearer that this one BID is on the inside surface, and not the outside, but if it were the outside then the later steps of carving the headrest to shape would be a LOT harder (especially since Figure 8 shows the outside being glassed with 2 BID). -- Marc J.

The height indicated is not exactly the good one. Compare with TB-1 chapter 18. There is about 3/4" of difference. If you build them as chapter 8,1 You'll need to cut them. For Mark IV only ...........perhaps Nat agrees with this.

Are these required to check for fit during the building process or do they just sit on the shelf until the final assembly? Here is my two cents worth: I ordered the chapter 8 kit without the seat belts and shoulder harnesses. I just couldn't see paying for these relatively "high dollar" items that would be left in the box for several years while I build the rest of the airplane. I looked at Nat's Cozy Mk IV at the Copperstate Fly-In, and from all appearances, the seat belts will just bolt right on to the standard plans built brackets. I built up the seat belt attach brackets per plans and expect that all will be well when I go to bolt on the seat belts. Of course, these are individually built planes and your results may vary. Perhaps we will hear from others on this subject. Good luck with your project.

The inertia reels are aircraft from Wilco (I think, if asked I'll dig out more info). They mount with one bolt 3/8" or 7/16" and had black webbing. I made a spreader bar for across the back of the neck, then shipped to Hooker Harness who sewed the reel web and shoulder straps to the bar. The lap belts are standard Cozy. The reels are mounted inside the head rests and on top the centersection spar. The hard points are similar to the usual shoulder harness points, which I also installed. I believe that with the added reinforcement plus being contained by the headrest structure have sufficient strength, but I have no proof of that. I believe that sometimes a yielding structure is better than a very rigid structure, where at some point something other than the human body gives, but then there may be another object causing other issues. The reels allow free movement, but do lockup on quick movement. When in moderate to severe turbulence, the lap belt tightness is most important, and have not noticed the reels locking or not locking. Have several times when lap belts not tight had top of cranium hit the plexiglass, but if the lap belts are tight, no contact. From: "Nat Puffer" Subject: Re: COZY: headrests Date: Sat, 2 Oct 1999 18:58:24 -0500 Doug, That is what we did on our prototype, but then when we stored our headsets in the strakes, the wires were always in the way of our seats and shoulder harness. So on the plans model, I put the outlets in the armrests, behind our elbows. Now we store the headsets in the strakes, and stuff the extra wires in the pockets, and it doesn't get in the way when we climb in or out. It works very well for us. We hope this helps you with your decision.

You have the front-hinged canopy, right? Are both headrests fixed to the front seatback in that configuration? I could consider that on the right headrest, but not the left one. The more I look at all that empty space in the right headrest, the more I think I should make use of it somehow. How about a flashing beacon light power supply? I need to have one somewhere, and that would get it out of the way, although it would require re-opening the headrest if it ever needs service. Does anybody know how often one of those needs servicing or replacing (I've never owned a plane)? Do they dissipate a lot of heat, too much to put it in an enclosed space?

Yes Are both headrests fixed to the front seatback in that configuration? Yes How about a flashing beacon light power supply? My strobe power supply is on the forward face of the firewall, within inches of the battery and master relay. To eliminate noise in the headsets, I had to install a relay to keep wiring very short, a filter capacitor, and then found the dress (location) of the short wires was very critical (trial and error). By mounting in the headrest, all those wires get much longer and would increase the chances of noise in the headsets. (strobe power supply) how often one of those needs servicing Yes in particular if out of service for some time, but they do go bad, there are some health sized capacitors inside. A few years back Terry Schubert had to pull a wing to replace his power supply, its mounted on the end of the strake. > Date: Sun, 03 Oct 1999 09:17:18 -0400 From: Jeff Russell Subject: Re: COZY: headrests DougSheph wrote: > Is there any reason not to do that?

I can't see how the headrests can be strong enough for their purpose unless there is glass on both sides, so the inside is the logical choice. Of course, the plans might have meant - glass both sides with one ply of bid, then cut up and glue together, but they don't specifically say "both sides" and generally they are specific.

The clue is that Step 4 says to round the edges, vacuum, and micro the foam before glassing the 2-BID. Can't do that if it's already glassed, right? -------> Let me know what Nat says to do.

Peter, On the Long EZ, the head rest pieces are cut to size and glassed on the inside with one ply. After partial cure, the pieces are assembled on the seat back with micro and small nails. After cure, remove nails, sand to shape and cover with two plies BID. P.S. The top of the head rest is a good place to mount a GPS antenna. Mine was an after thought and was easily changed, but doing it now will save time later. Mike Bowden From: "Doug Shepherd" Subject: COZY: shoulder support nutplates Date: Sat, 20 Nov 1999 20:13:38 -0800 I installed the shoulder support nutplates as follows: I flox'ed the birch inserts in place, then installed the pads to bring them flush on the top side of the foam. Then I drilled the 1/4" hole, put some Vaseline on the bolts, put some flox under the nutplates, and screwed them together with some washers under the bolts. Before removing the bolts, I Dremel'ed the mounting holes on the nutplates clear, then drilled holes and installed #2 x 1/4" screws. The #2 screws don't have much strength but they do pin the nutplates, preventing them from torquing when the bolts are installed. Then I put some scotch tape on the outside, dripped some candle wax into the hole, removed the tape, then installed the shoulder support and glassed over the outside. Then I just had to drill through the outer two layers of fiberglass and knock out the wax plug. It seemed to work pretty well. All the holes line up, the threads are clean, and the nutplates take plenty of torque without any cracking or other scary noises. Doug Shepherd
