I have a few questions. The drawing calls for a 1 3/8" diameter tube for bending the leading edge. I'm thinking of using the vacuum method, and this will likely be either next weekend, or within a few weeks. Does PVC pipe have adequate rigidity? Are 12 foot lengths commonly available? If not PVC I'm concerned as to what I'm going to do with a 12 foot length of steel pipe once I'm done. This is a scratch build, so please don't tell me they come pre-bent.

I did something close to this, but I cut mine over size by 3 inches and trimmed to fit after. This allowed me to screw the boards to the trailing edge and not worry about being square. This was for the stab and elevator and not the wing. I would think it would work for the wing, but I have not been there yet.

The planes stated empty weight is 903lbs, so that gives him a 417 lb useful load. He had to over-pitch the prop to keep the speed low. No wheel pants or fairings either. With 2 FAA sized folks you can carry a little less than 13 gal of fuel for an engine that burns about 6+ gal an hour You get all of the RV costs, but none of the performance. Why anyone would do this is beyond me, but hey it is experimental aviation. :D Jon P.S.

It doesn't even seem close to an LSA. Gross weight is around 1750, Minimum engine 118 Hp gives 165 mph cruise (give or take) empty weight over 1000 lbs 36 gallons of fuel. Somebody is really stretching the point. Maybe they just were trying to fit in at the LSA show.

Obviously you know, or you wouldn't be able to recommend 3/4" spacers for some combination of prop and crush plate that you know about. I thought there'd be enough corvair builders on this list using this spinner that someone might know the dimension, but I'll try asking on the RV board. Thanks for your post anyway.

I will post a pic of one I did and you can see it isn't that hard to do. I like the Van's front bulkhead much better than WW's because it makes the spinner rigid and WW's can be moved from side to side but if you can't get one what's the point. > b] -------- Scratch building XL with Corvair Engine Read this topic online here: http://forums.matronics.com/viewtopic.php?p=226615#226615 ________________________________ Message 12 ____________________________________ Time: 06:31:31 PM PST US Subject: Zenith-List: Re: Leaky Prosealed Tank From: "leinad" A follow up to my leaky tanks post Two of my 4 tanks leaked. One leaked on the front seam in 2 spots. The other leaked around one of the threaded fittings. Rather than using a sloshing agent I tried the following. The leak at the threaded fitting was right in a corner that I packed with proseal mixed with a little bit of fiber glass. This was done on the outside of the tank. There were lots of rivets shop ends poking out for the proseal to grap onto. The other one was on the long straight seam. I bent up a U from 5052 aluminum and after removing the rivets from the leaky area I wrapped the seam with this U and drilled it to use the same rivet holes. Next I stuffed the U with proseal, hammered it on with a mallet and set the rivets. I should know late tomorrow if this worked. Here's a picture of the patch.

Gig (William Giacona) came through for me. The distance is "approximately" 4 1/4". So my 3-3/4 prop with 1/4" crush plate should fit with 1/4" (spacers) to spare. Thank you Gig!

But if you simply use the numbers I gave you should be able to have come up with the distance. Here is your post or was this someone else's it sometimes gets confusing I also have Van's spinner FP-13 but the rear bulkhead bolt holes do not fit WW hub and the front bulkhead would not fit Warp Drive prop at all. I emailed WW numerous times inquiring about the front crashplate/bulkhead but he would not reply. Can you post the bolt hole patterns and how you got the front bulkhead to work?

I did the bending solo on top of my table. That's one of the things I like about this design, one guy can do most of the work. If you are going the vacuum route I would imagine rigidity and straightness of the tube will be important. Also you will need to keep the tube aligned to the skin during the process. -------- Ron Lendon, Clinton Township, MI WW Corvair with Roy's Garage 5th bearing Zodiac XL, ScrapBuilder ;-) http://www.mykitlog.com/rlendon Read this topic online here: http://forums.matronics.com/viewtopic.php?p=226647#226647 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message zenith-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Zenith-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/zenith-list Browse Digests http://www.matronics.com/digest/zenith-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.
