Yes- the rivets go thru the cover then thru the nut plate. The cover is then put inside the wing access hole, and the machine nuts go first thru the wing skin and then thru the cover and into the nut plate. Using the flat head on your rivet gun will flatten the head of the rivet. You might want to bevel the hole in the cover to compensate for the flatten rivet head. I personally didn't.Don't worry about the end of the rivet. It's inside the wing and will not be in the way of anything. I'm not sure if I understand your concern about pulling the rivets. The only tool you need is your penumantic rivet puller or if you don't have one, your hand puller with the flat head on it. It's the same puller you are using on the rest of your plane. Hope this helps.

Nutplates are a venture into the world of solid rivetting techniques. The countersunk solid rivets you have are what holds together pretty much the entire airframe of a Vans kit for example. The anvil technique you describe is what is known as "back rivetting" but you don't do it with the cover plate in place because the rivet heads will make a mess of the cover plate as they get driven back thru. Back rivetting is normally done with $200 air chisel, but I wouldn't do this as you need a the special head to stop it slipping off the tail of the rivet. I would use a steel shim instead of the cover plate to hold the rivets in flush. If you know of someone building an RV ir similar you could borrow a rivet squeezer with flat heads...This simply crushes the rivet between the jaws. If your really macho even a pair of large pliers will do the job. The rivets are not structural so you don't need a perfect set for a nutplate.

The reasons Jim mentioned about getting service and help virtually anywhere is the main reason I chose the O-200. That and it's long proven record of durability and TBO. Weight is certainly a consideration, but it's lighter than any of the Sub conversions (have built and flown 2 of these now) and with lightweight starter and alternator, it's almost identical to the Jab3300. I got mine on eBay for $3200. But I had some serious conversations with the guy first and you gotta know, I have built engines all my life from lawn mowers to 300 ton mining trucks. This one needed some valves, guides, and cylinder work that cost me $350 total at the local auto machine shop, as well as the normal bearings, seals, gaskets, etc. Granted, list prices for parts are way out of line for these engines, but shop around and relatively cheap parts are not hard to find. The only thing I did not get cheap was main bearings - $700 from Superior, but that is still quite a bit less than list. I was also graced with the fact that things like mags, carb, oil pump gears, crank shaft and cam are all within new specs so no extra expenses there. For those of you who have even basic mechanical skill, the O-200 is an extremely simple engine internally and tolerances are very loose compared to most - air cooling requires a bit more room to handle the wide variations in operating temps. It should be no real challenge to most folks with overhaul manuals and specs also readily available. The engine is now completely built, to factory tolerances (blueprinted) for a total of $4900. That includes spin on oil filter adapter, new oil cooler, and Ex-Cell-O fuel injection system. I'm not sure I'll use it, but would love to upgrade to electronic ignition and fuel injection. This is just my opinion of course, but I made the right choice and it seems that everyone's opinion of purchase prices and overhaul costs are based on certified aircraft and A/P overhaul history and not experimental, do-it-yerself homebuilding. Now, let the games begin.....!!!!!!!!!!!!

Thanks, Paul. That was a very interesting story about engine selection and rebuilding. (I still plan to buy a new Jab 3300, but I don't have your engine experience.) I can't say what will happen if you put the fuel injection on the O-200, but I can tell you those planes I have flown with fuel injection were a lot smoother than anything with a carburetor. You also gain by not having to install carb heat. Aircraft fuel injection units seem to include automatic air intake port selection which takes care of any icing problems. Also, with real fuel injection (like on Diesels) the fuel is not mixed with air until it is in the cylinder so icing is unlikely anyway.

Many people have offered up very good advise so I thought I would just add a few other points. Anytime that you are working with aluminum as for cutting or grinding you need to lubricate the blade/tool. Aluminum melts at a rather low temp and because of that tend to stick to the tools doing the cutting. You've might have seen this when drilling a thick piece of aluminum where the material will stick to the tip of the bit. Using the miter saw to cut aluminum is something I've done for years. I use a little WD-40 sprayed at the cutline to lubricate, works very well. Bandsaws are as well a valuable tool. Here I use parafin wax to lube the blade, just cut into the wax abit to allow the teeth to become filled with the wax. This reduces the blade friction as well as helps prevent the blade from becoming peened (plugged) with material. Also if you using a disk or belt sander to dress your part if you sand on a piece of wax first your abrasive won't peen (plug) up as well. Safety was covered in another post, securely hold part in place prior to cutting, be aware that if you are cutting off small pieces that they can and will fly up and try to impale you. I hope that this information helps. Bill Jeffries, Iowa.

I've been building/rebuilding an HDS since 2003, but figured I'd bugged Mac enough and figured I'd join the club. Does anyone have a loft (X-Y coordinates) of the cutout for the nose skin to tip rib juncture? I'm having no luck with the "Pen on a stick" method called for in the builder's manual. What kills me is, Zenith provides a loft on 6-V-9 of the plans for an HD, but leaves you hanging if you're building an HDS. The HD has a larger, constant chord nose rib, so what I figured I'd do is lay out the HD loft in AutoCad, measure the nose to spar distance on my project, get a ratio between it and an HD nose rib, and shrink the full scale drawing to fit. Figure it would give me the contour, and I could trim from there. I'm going to start soon as I hang up BUT- I'll keep checking my e-mails, and if anyone gets back to me with a loft, I can stop backyard engineering and get back to building. Thanks.

Developed length is what you cut the raw aluminum to before you bend it. If you're going to make a U-shaped channel that is 20 on each flange and, say, 50 in the web, your developed length will be 20 plus 50 plus 20, plus an allowance for each bend. Your bend lines will use up the difference between finished and developed. In all practicality, though, few people are that precise in their bending. But it's a good goal to shoot for.......for which to shoot.

The reasons Jim mentioned about getting service and help virtually anywhere is the main reason I chose the O-200. That and it's long proven record of durability and TBO. Weight is certainly a consideration, but it's lighter than any of the Sub conversions (have built and flown 2 of these now) and with lightweight starter and alternator, it's almost identical to the Jab3300. I got mine on eBay for $3200. But I had some serious conversations with the guy first and you gotta know, I have built engines all my life from lawn mowers to 300 ton mining trucks. This one needed some valves, guides, and cylinder work that cost me $350 total at the local auto machine shop, as well as the normal bearings, seals, gaskets, etc. Granted, list prices for parts are way out of line for these engines, but shop around and relatively cheap parts are not hard to find. The only thing I did not get cheap was main bearings - $700 from Superior, but that is still quite a bit less than list. I was also graced with the fact that things like mags, carb, oil pump gears, crank shaft and cam are all within new specs so no extra expenses there. For those of you who have even basic mechanical skill, the O-200 is an extremely simple engine internally and tolerances are very loose compared to most - air cooling requires a bit more room to handle the wide variations in operating temps. It should be no real challenge to most folks with overhaul manuals and specs also readily available. The engine is now completely built, to factory tolerances (blueprinted) for a total of $4900. That includes spin on oil filter adapter, new oil cooler, and Ex-Cell-O fuel injection system. I'm not sure I'll use it, but would love to upgrade to electronic ignition and fuel injection. This is just my opinion of course, but I made the right choice and it seems that everyone's opinion of purchase prices and overhaul costs are based on certified aircraft and A/P overhaul history and not experimental, do-it-yerself homebuilding.
