    From: "bcchurch" <bcchurch@yahoo.com>
    Howdy Jake, I got my tools from different sources. No clear idea if I saved much money because I got more / different items than what is included in the Zenith kit. I think I did save a little money but spent more time. Picked up extra used clecos from another builder - I think the number recommended by Zenith would be sufficient but having extra is nice. I was not impressed with the pneumatic rivet gun that I bought from Zenith. Mine tended to have a recoil that made dinging components a real risk. I was given a pneumatic riveter from Harbor Freight (ITEM 93458-1VGA) which I like much better. The HF unit is only about $30 and has the same rivet head thread pitch as the Zenith unit so I was able to use the Zenith-modified heads. You might want to take the time to browse some sites like Avery, Brown Tools, Cleaveland, etc. and see what's on sale. Harbor freight can have some good deals too but their quality is not as high as others (but sufficient quality in my opinion). Also, used tools sometimes show up on vansairforce.com in the classifieds forum that can be a good deal.

    If I had to buy stuff it would be three times as many cleco's as zenith suggested but that was back we had to drill all 12,455 holes and I was a bit anal at wanting the plane to be somewhat straight <G> I would get twice as many ratchet straps for closing up the wing skins but that can wait till ya get to that part and Walmart would probably have them on s ale @ 4 for 14 bucks.

    Subject: Re: Top Longeron Gusset (7F3-3SP)
    Wow, that's a long time ago! I'm building an 801, but I assume that the gusset is similar. I remember remaking those over and over again--but I don't remember exactly why. (Probably because of the difficulty of precisely positioning all twenty-some rivet holes to match up with the holes I had already drilled in the longerons and cabin frame tubes.) I made them of heavier stock than the pieces supplied (0.063 vs. 0.040)--because Chris put out a note advising builders to replace the top channel (across the front edge of the rear fuselage top skin--at the top of the door posts--with heavier material than the kit supplied, for structural reasons, and I figured if the channel is heavier then the gussets that attach it to the longerons and top cabin frame tubes should be heavier too. I therefore made the gussets longer, long enough to reach an additional longeron rivet, and filed down (tapered the thickness of) the rear ends of the gussets so the rear top skin, which goes on top of the gussets, would not be bent over a sharp thick edge at the rear end of the gusset. To answer your question, I would tend to assume that after 24 years, if the structural design of the -701 was deficient, that would have been determined by now. I don't think it would do any harm to make the gusset wider--enough to pick up another rivet in the top channel, but it probably isn't necessary. You may recall that an early prototype of the -801 crashed after apparently shedding its wings in flight in California a few years ago. That plane probably had the thinner top channel, (the advice to make it thicker came out after that crash) and I believe it had the very heavy in-line 6-cylinder 210hp LOM engine and propeller, which would have exceeded the fwf weight limit ZAC specifies now by at least 60 lbs, I'd estimate, and would have required ballast in the tail to balance all that engine and prop weight. Mind you, I am speculating here, but I assume the modification to the top channel arose from that crash. I am not aware of any similar structural failures in the -701. Use your best judgement.

    Subject: Additional L angles in fuselage.
    From: "Harvey Richards" <lisa.richards@ns.sympatico.ca>
    I have seen where people have done the diagonal additional L bracing to cut down on oil canning. I am at that stage and have been wondering what to do. Some have gone with diagonals and some with complete X's between the Ls shown on the plans. Would not going straight across,parallel to the Ls, shown on the plans do the job. One could then tie them together with .025 gussets as already shown on the plans. This would take less L angles, be lighter and cut the unsupported distance in half also. Any thoughts?

    Thanks also Larry. I can see the advantage of diagonal L angles for bracing strength but believed,maybe mistakenly, that the L angles were only to provide stiffness to the unsupported sheet metal. I was looking for a reason why the diagonal was better as there may be something I'm missing. -------- CH 701 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=222644#222644

    I put X's in them, though maybe a single diagonal would be enough. Even slipping as much as possible I've had no oil canning at all, except the bottom hatch which was cured by putting in an X brace. I'm not sure how everyone else does it, though when I looked for photos on the internet most that I saw seemed to have X braces. ----- Original Message ----- From: "Harvey Richards" <lisa.richards@ns.sympatico.ca> Sent: Saturday, January 03, 2009 2:30 PM Subject: Zenith701801-List: Additional L angles in fuselage. > <lisa.richards@ns.sympatico.ca> > > I have seen where people have done the diagonal additional L bracing to > cut down on oil canning.

    Hi Jake; The Zenith tool kit is reasonable with reservations. I did not buy the air drill from them I found a Sioux air drill on sale, I thought Zeniths price for it rather high. There are nowhere near enough clecos. I have double the number of 3/32 and 1/8. It is often handy to leave a slat or a flap unriveted for a while hence the extras.You will also need a few, say ten, 3/16 clecos when you fit the slats to the wings. My EAA Advisor also sugested that when I needed to test bolt parts together that I not use the bolts that are in the hardware kit but to buy a box of 25 3/16 nuts bolts and washers. He did not like the idea of using the "real" bolts during the building phase. I found a chip chaser to be handy. I bought a right angle drill kit this I found indispensable in the tight corners of the wings and fuselage. I also bought a bunch more #20 #30 and #40 drills. I originally thought I would sharpen dull drills, it is not worth it. One of each size in 6 inch and 12 inch length is very useful too. You can never have enough tools!

    Subject: Re: Additional L angles in fuselage.
    Harvey, The angles provide a best way to reduce the large unsupported area and help add to the structural integrity of the fuselage. Beyond that, the addition of duct tape strips broadly spaced will dampen the sound a lot. The first three bays behind the seats are the worst and the rearmost is probably a hard one to get angle into, but worth it. Larry do not archive Harvey Richards wrote: > > Thanks also Larry.
