    Well, I'm done making progress for now. Going to sea in two days to scrape up a some more rent money. Chapter 4 and 5 are done, and I'm ready to start assembling the tub. I'll pick it up again when I get back. Thanks to all for the advice and assistance, especially Mfryer, Tmann, Limo-EZ.
  2. +1 on the Doug Fir Longerons and also the plywood. Like mentioned above, clear mahogany should work for the longerons as long as the grain is straight for the length of the wood. I wouldn't use anything with the grain running at an angle or swirly grained wood of any type, and I'd avoid the heavier varieties (like Jatoba). I used "Loyds-of-London grade" okoume 6mm plywood for the firewall and also the instrument panel, F22 and F28. This plywood is used extensively in boat building. Boats take a bashing. Yes its heavier than the plans material, but after all the holes are cut out of the bulkheads its not MUCH heavier, and it was available across town. (unlike that silly red foam stuff)

    I did recalculate. A little less lift but a little more windage. But thats ok because I'm using a heavier engine and a smaller prop. The trajectory should still be about the same. Curtain liner? No way man...old socks!

    Clear, straight, tight-grain Douglas Fir. Aircraft grade. (I graded it).
  5. Looks good man. Now its REALLY looking like you've got an airplane in your garage. Lots of people have lots of things in their garages...but I'm betting nobody else in your neighborhood has an airplane.
  6. In the FAQ section they claim it would be perfect for a pusher configuration like a LongEZ or Varieze. You're right about the lawnmower cable - its junk. I think this quadrant could be adapted pretty easily to use a red Morse type 33c marine push-pull cable, which works really well if you get all the slop out of the linkage and anchor the ends securely. They last damn near forever too. There are other cables and ends available that can be adapted as well. My KTM uses teflon lined cables for clutch and throttle and they work great as long as you keep the dirt out. You can order custom-made cables from these guys: http://www.motionpro.com/custom/index.php

  9. Thats exactly what I have been thinking of: Both tanks drain into a sump from the strakes with no valves. No screens on the strake drain tubes, and large enough diameter tubing to allow any contaminants/water to pass directly into the sump. (How would you clean a screen inside the strake tank, anyway?) A drain on the sump to remove any contaminants and water that ends up in there. Maybe a bunghole for a cleanout too. In-tank fuel pumps submerged in the sump to eliminate vapor lock. Dual fuel filters incorporated in there somehow, with ability to run on either.

    I'll definitely install the sight glasses; partly because I've already carved out those damn holes, but mostly because I'm a big believer in passive indicators. I'll have mechanical engine guages too, at least for oil pressure/temp, water temp and fuel pressure. I gained a bunch of panel space with 4" wider and 4" deeper fuselage. I wish I had known about the Berkut sightglass relocation but I didn't, and I'm more concerned about making progress than assessing every little detail at this point...so onward. Maybe I'll add them later.

    Landing gear bracketry. Cost me $60 in materials but I still need real 8" bolts.

    redundancy

    How about 2 GIB's. One in case the other "has a headache". Oops. Just saw that. But seriously - if you put too much of that crap in there you'd spend all your time messing with the gadgets. What these planes really need is a shaft brake and a BRS parachute system.

    Thats right, he is. I looked his plane over one day, but I had forgotten about that. I don't know if Al has even fired his plane yet, and I'm sure he has not flown it since installing the Suburu 6 cyl, so the jury is probably still out on his dual ECM setup. At any rate, I've got a ways to go before I need to worry about it.

    How about 8 ignition coils? Theres some redundancy. All controlled by the same engine controller though. I don't know if there is some type of switch that will allow you to switch between two separate engine controllers, but there might be. I know Tracy Crook(?) at RWS has a dual ECM system for the rotaries. Hey thanks for the help last night Martin.

    Yeah...so I'm told, and I shoulda known that. It was a pain in the ass to get the glass to lay down in those holes. However, I guess I'll put them in now that I did carve the holes, cause if all the electronics crap out it might be nice to know if there's fuel in the plane. Of course; at that point I would be a glider. Perish the thought.

    But not quite. I didn't have enough clamps to do both lowers

    HOT DAMN! This Fein tool is the best thing since sliced toilet paper!

    Progress

    I peel-plyed (peelplied?) all the edges of course. The IP came out fine - the top half that you look at all the time came out perfect...its just a little bit imperfect lower down on the sides and the center partition. The sides get covered with those armrest things and the center I'll coozy up if necessary. Zolatone paint would hide any imperfections anyway. 2012???? Well...the side foam is already cut and formed, and I'm going to get wood tomorrow (he he) and cut the longerons out on the tablesaw. Then I'll make seatbacks and mock the whole thing up again. Once I'm satisfied with the locations of everything I'll mark it out on the sides and then glass them up. I just gotta know where to peelply, and I gotta figure out how I'm going to mount the main gear. (as per plans or Cozy style) So maybe a little sooner than 2012. Besides...we're ALL going to be done in 2012 anyway. Haven't you heard?

    I did my first layups tonight...glassed the back of the F22, F28 and the IP. I won't know how they came out until I peel off the plastic sheeting, but I think I squeezed all the excess glue out along with all the air. Waiting on the 7725 BID to glass in the F22 doubler as the 7781 is not nearly pliable enough to be going around any corners. That stuff is a fairly tight weave...probably why its stronger. One thing is for sure; the plans say you can lay these bulkheads up using strips to save BID cloth and thats not a good idea. Especially on the IP, which you're going to have to look at all the time. Its better to just cut out two full layers of glass and eat the scrap than try to piece it together. I should have known better but pieced it together anyway. Now I'll have to smear some micro on it to smooth out the joggles. Luckily, I've got my trusty Porter Cable vacuum sander. Makes quick work of anything you go after with it...and the shop vac hoovers up 90% of the dust. I can smooth out that IP in about 10 minutes...but its just another thing to muck around with because I was being cheap and trying to save glass. Stupid F%#&@*$ Me...I have plenty of glass. The Pro Set epoxy seems to be nice stuff though - fairly low viscosity and doesn't smell hardly at all. I probably used too much, and then squeegied alot of it back out again after covering with a plastic sheet. I made a heat tent out of two 24"x24" 400w radiant panel heaters set in stands on either end of the layup, with cedar deck boards laid across between them and a sheet draped over the top. We'll see if it works. Ok, thats it. Miller time.

    Damn...I'm jealous. Are there palm trees? Its gray and nasty here.
  21. All the more reason for my decicion not to buy somebody else's project.
  22. I once heard a rumor that there is a certain bay known for pirates...where some very interesting things come down in torrents. ARRGH ! !

    Are you not in Tacoma Steve? I got your PM and will give you a call soon.
  24. Thanks again Joe - this is the kind of info I needed. I am in the process of figuring all this stuff out right now. I don't think I'm going to jig the sides curved though - I'm just going to skin them flat as per plans and then put the thing together. Hopefully it won't end up looking too much like the Fedex truck. I made everything 4" wider across the board. I havent cut out the seatbacks yet but I'm going to go and do that now, then jam them in between the sides and see how it looks. This foam-whackin stuff is kinda fun. I haven't started the messy part yet.

    Uhhh, well....my plans say to jig it upside down and the top of the sides are straight and flat, so it only makes sense. It's not a Cozy. Its kind of a Long-EZ...or maybe more like a Fat-EZ. Still waiting for UNI from ASS. ASS must stand for Always Ships Slow?
