From: "Gig Giacona" --> Zenith-List message posted by: "Gig Giacona" Two questions for you Larry. First, Could you take some closeup photos of the installed fasteners on your wing lockers? Or point me somewhere I can get instructions on how to install them. I've put off their installation and I'm goinfg to have to install them sooner or later and I'm not really sure how they are installed. Second, did you make those inspection point springy things or did you buy them and if so where? GigG larry(at)macsmachine.com wrote: > Allen, > Don't use any power equipment.

Since the bottom is not flush with the rudder skin it would make a scoop whenever the rudder was not centered. I was thinking of riveting a skin over the area to make it more aerodynamic then realized that if Chris thought it was important he would have changed it.

"Drill press". The magic word! I haven't that kind of machine, since my workshop is a way too small for it. Handheld battery (accu) powered works fine too. Normally their rpm is slow enough with reasonable power and most of them has adjustable friction lock, what helps a lott, when knife stopped suddenly. ________________________________ Message 10 ____________________________________ Time: 09:57:10 AM PST US From: "Gordon" Subject: Zenith-List: driving a flycutter --> Zenith-List message posted by: "Gordon" I was concerned that I could really screw up a perfectly good chunk of aluminum with a flycutter. I used a flycutter or hole saw to make plywood templates. I then used a hand held Riobi battery powered laminate trimmer with a 1/2" router bit and top bearing that would run around the inside of the template. Makes very clean perfect holes and shapes.

What worked best for me is a unibit for the corners and a Dremel with a cut off wheel for straight cuts, works great and is very easy to control. I have also used the Dremel drum type sanding wheels to smooth and finish the transition from straight to the radius. I consider the Dremel to be one of the most versital tools I have. I also use the fly cutter for large round holes at very low RPM, in some cases I drill the hole under power and turn the fly cutter by hand to finish the hole, it is really easy to do.

The problem with Dzus components is picking the right sizes. See the following links. http://www.macsmachine.com/images/cowling/full/Dzustools.gif http://www.macsmachine.com/images/cowling/full/Dzusdimples.gif http://www.macsmachine.com/images/cowling/full/Dzusspring.gif The links show a Dzus tool set, the dimpled set of holes that are needed and the back side of the installed Dzus spring. I use A4 rivets to secure the springs. Dimple the material for the head and use the flat surface on the pop riveter to secure. Dzus springs are S4-225s. The Dzus studs are S4 (1/4-inch) and are -50 length. The Dzus grommets are GB4B. You need a set of dimpling dies that can be pulled with your pop riveter. I had to make a similar dimpler for the large stud holes to dimple them too. You need to make a steel drill template to allow marking and drilling accurate holes for the springs and Dzus studs. The holes for the studs should be 5/16-inch and the holes for the rivets are 1/8-inch. You need to make a shim to adjust the springs to the correct height from a smooth surface for uniformity. The installed spring needs to be centered across the stud hole accurately and can be done visually. All spring height and centering adjustments can be made by hand with two pair of pliers. Also, you want to install the springs in a manner that leaves the slot aligned with the wind or uniform to the rest of the installed studs. Now, as you progress in making or obtaining these parts and making the tools, don't just start on your airplane. Make a test sample installation on one or two sample patches of aluminum. When you're satisfied that the installed Dzus pieces are done correctly, then start on your luggage area. I prefer the Dzus fasteners to the newer components because they're simpler. If you aren't satisfied with the fit, you drill out the rivets as you would for any other redo and salvage the springs. You might need to tighten the spring for the rivet or not but I've not had any come loose since they were installed. The spiders for the inspection plates are of my own design. The spiders have half an inch overlap on the inspection holes. The centers are held by an 8-32 screw in a rivnut. The .040 inspection plates were spun in a lathe to remove half an inch of material thickness or .015 so the plate stays centered in the hole and the spider is adjusted to a consistent height that snugs the plate and won't let go. You should try making one. They're not really hard to do. If you need to put one forward of the spar underneath, I recommend you add a leading edge screw and tinnerman for security. http://www.macsmachine.com/images/wing/inspectionpanels/full/spiders.jpg http://www.macsmachine.com/images/wing/inspectionpanels/full/accessspydersafety.gif Good luck, Larry McFarland- 601HDS at www.macsmachine.com Gig Giacona wrote: >--> Zenith-List message posted by: "Gig Giacona" > >Two questions for you Larry. > >First, Could you take some closeup photos of the installed fasteners on your wing lockers?

Goodings" Subject: Zenith-List: Re: Access panel and wing lockers --> Zenith-List message posted by: "John M. Goodings" I made wooden handles for one end of hacksaw blades - both the 10" long x 1/2" wide ones (for straight cuts), and also the 6" long x 1/4" wide ones (for curved cuts). They don't distort the edge of the cut like snips do. The bigger blades are easy and quick to use. The small blades are a bit tedious.

I have gone over and over this. I drilled the bottom skin and through the hinge without going through the top skin. I put one rivet in. This doesn't look right. The rivet holds the skin open, plus it will be constantly rubbing against it. Does anyone know if this is correct. I don't see why I can't just drill through the whole thing and rivet it completely. Any suggestions? I guess I should call ZAC tomorrow, but I wanted to finish it tonight.
