I think it's easier to get in and out of than a Cherokee is though because you can get into both sides. I always thought you have to be a contortionist to get into the Cherokee because of only having a right door. -------- Mark s/n 094 My Build Site: http://www.mykitlog.com/stephen363/ Read this topic online here: http://forums.matronics.com/viewtopic.php?p=336986#336986 ________________________________ Message 3 _____________________________________ Time: 04:44:35 AM PST US Subject: Zenith640-List: Re: A Newbie from Malaysia From: "super58d" Scott and gang, I reviewed the errata again and found something of note. I bought those new CAD plans when they came out about a year ago and found something interesting. Here is the errata in question: "Drawing 640V1, Revision 4 - Item 1, Wing Spar Extension. The plans dimension "~405" to the first lightening hole. Change this to 350 mm. 640V2 wing spar extension assembly shows the lightening hole half-way between the two (L) pieces. Adding the dimensions: 25 mm for spar cap overlap + 225 mm from overlap bend to first (L) + 100 mm from first (L) to center of lightening hole = 350 mm." My old plans had the distance at 405 like you said Scott, but the new CAD plans have it as approx 305mm. Not the 350mm The errata page said it is supposed to be. Zenair obviously fixed the mistake (but left the revision number the same) but now we need to figure out if the 305mm or the 350mm is correct. Both pictures of 640-V-2 show the lightening hole slightly closer to the inboard "L" angle than the outer one. There is nothing out there really so I doubt 45mm difference will matter at all though. Scott, I didn't want to update the errata page until we got a resolution on which number is correct. -------- Mark s/n 094 My Build Site: http://www.mykitlog.com/stephen363/ Read this topic online here: http://forums.matronics.com/viewtopic.php?p=336987#336987 ________________________________ Message 4 _____________________________________ Time: 05:18:25 AM PST US Subject: Zenith640-List: Re: A Newbie from Malaysia From: "pilot4pay" stevetosh wrote: > Hello Guys, > > Please which one is better about shear, i can found hydraulic which is expensive, and there is manual shear machine. So which one should i go for. But I found a shear plan on 601.org but dont really understand the plan. Any advice? Unless you plan on making a commercial venture out of your kit building, a manual shear should be just fine. Many get by without a shear at all, but as a scratch builder, it probably would save you time. On thin stock, scoring with an Olfa knife works very well. -------- Craig Smith CH640 builder SN: 0078 "Just think how stupid the average person is, and then realize that half of them are even stupider!" --George Carlin Read this topic online here: http://forums.matronics.com/viewtopic.php?p=336990#336990 ________________________________ Message 5 _____________________________________ Time: 04:22:40 PM PST US Subject: Zenith640-List: Re: A Newbie from Malaysia From: "Scott Stewart" Hi Mark, I went out to the hangar where my wings are stored to measure and photograph the lightening hole. I used a crude measuring tape in the photograph just to demonstrate the distances. (And please forgive the dirt collected in the wing while in storage.) You can see the rivet line versus the position of the lightening hole. I suggest the 350mm dimension, but you can change this +/- 30 mm without affecting anything. Moving it 45 mm is too much. Notice how the hole would overlap the vertical "L" positioned at 250 mm from the edge of the wing spar extension. -------- Scott Stewart s/n: 0092 Building from plans Rudder and Stabilator complete.

The reason why I asked is that I always hear about how small the rear seats are, but they look pretty similar to the rear seat area of the older Cherokees. Good luck on your project! -------- Jon McDonald Building Sonex #1287 Next up CH 701 :D Read this topic online here: http://forums.matronics.com/viewtopic.php?p=337096#337096 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message zenith640-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Zenith640-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/zenith640-list Browse Digests http://www.matronics.com/digest/zenith640-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
