Lynn Erickson Posted May 10, 2009 Share Posted May 10, 2009 Well! maybe but I don't see any other cowlings that aren't symmetrical. So no I don't think that was it, if it was, that seems a bit silly to me. It's off in places that have nothing to do with the engine. Funny thing is I have a set of LongEz cowls that had the same problem. Also I have a set of 540 cowls that don't have those discrepencys (way more symmetrical). The 360 cowls didn't realy line up the way they where supposed to at all. so I don't think it was done that way on purpose. Besides they look alot better symmetrical. I talked with a few LongEz guys who did the same thing I did. The whole thing was just out of whack. It was kinda like someone held a heat gun to the left side and it just kinda wilted. The bottom was worse than the top. I got them just about perfect now Tony that wilting as you call it is caused by the manufacturer. if the cowing is pulled from the mold to soon the resin is still in a green state and can warp or sag. the tops of the cylinder is where is seems to show up the most. also many of the molds that where made are polyester boat resin and it keeps shrinking with time.

tonyslongez Posted May 10, 2009 Author Share Posted May 10, 2009 Lynn That could very well be. I think that aside from the shrinkage a bit of TLAR creeped into the plug making portion of the cowls probably due to time constraints, couple that with shrinkage and you have a mess. I do believe that all the parts are post cured in an oven. I'm sure the molds where too. If the cowls where symmetrical to begin with I can handle a little shrinkage but they weren't. I can't speculate as to the resin make-up of the molds. I don't know. I mean some of the areas seem to go way beyond shrinkage. I have number 17 I can't imagine that much shrinking took place to get them that far out of whack. Tony Quote Link to comment Share on other sites More sharing options...
tonyslongez Posted May 16, 2009 Author Share Posted May 16, 2009 O.k lots of things to talk about in this post. Last week I said I thought I had pics of our cowling plug and I found them here they are. Also, I'm starting the process of creating molded ailerons. I have pics of the Berkut molded ailerons and we'll get started building those. Dale and I will work on the molded canard and wings this week. I had some issues with the tool changer on the HAAS so I took some pics so you could see what I was doing. I know it's not building an airplane but pretty cool I think. Pic 1) Here you can see the bottom cowl and the body filler we used to make the cowl symmetrical. Dale made a very slight change in the rear of the cowl to ease the radius around the intake scoop. So it kinda melts into the rear of the cowls as opposed to being so pronounced. Pic 2) Again in this pic, easying the radii around the muffler and cylinder blister. Pic 3) Plug clecoed to the rear turtle deck. Pic 4) The cleco is in the way, but I assure you, the cowling and the top strake are absolutely a perfect match. Pic 5) More body filler Quote Link to comment Share on other sites More sharing options...
tonyslongez Posted May 16, 2009 Author Share Posted May 16, 2009 Pic 1) O.K. aileron rib layout. Basically a piece of flat stock with some ribs drawn on it. Pic 2) Here is the bottom aileron skin this layup has a piece of 1/4in foam layed up with 2 plys of bid top and bottom. the foam is slightly tapered in the rear Pic 3) What I want you to see here is how the layup incorporates a "tube" so you just slide your steel rod into the tube and away you go. Pic 4) This is the bottom surface of the aileron it's hard to see but there is a slight joggle where the white primer ends. Later you'll see why that's there. Pic 5) Here is the top of the molded aileron this is just two pieces of 1/4in foam with two plys of bid top and bottom, the face has the aluminum plates embedded in it for the hinges. More on that later. Quote Link to comment Share on other sites More sharing options...
tonyslongez Posted May 16, 2009 Author Share Posted May 16, 2009 Pic 1) Here is my new Haas machine in it's final resting place the machine weights in at a whopping 8,000 lbs. I used a 15,000lbs capacity fork lift to get it off the truck lots of fun. I added the rails to the front of the machine to hold some tooling. Pic 2) As I mentioned before. I was having some issues with the tool changer mainly because it was really dirty and full of chips. I don't think it's been serviced for a while. the pics out of order this is the carousel all cleaned up Pic 3) Got most of the chips out of the carousel. I had to tighten the allen bolts on some of the tool pincers. Part of the service. Pic 4) Here are the covers for the carousel which is kind of a boring pic but you can see how the paint is starting to come off . The covers are stainless, and with the paint flaking off it really gummed up the slide covers. Dale and I stripped them today, and now the're ready for paint. That's it for today more tomorrow.

tonyslongez Posted May 22, 2009 Author Share Posted May 22, 2009 I've been waiting for the aluminum to get here that I'm going to use for the aileron molds. Unfortunately U.P.S. lost it. They report I'll have it on Fri. We'll see. I took some time to put the tool changer back together on the Haas. I had all the parts powder coated, looks pretty good. Pic 1) The door of the tool changer slides out as the tool is being extracted this action keeps the chips out of the tool changer. Pic 2) In case anyone needs to change a door or spring in your Haas tool changer, You have to load the spring from the back. The weight of the cover is enough to keep the spring in place while you insert the cap screws. Tony Quote Link to comment Share on other sites More sharing options...
tonyslongez Posted May 24, 2009 Author Share Posted May 24, 2009 Here is the final hinge assem for the berkut canopy. The nice thing about this, I can waterjet cut pretty much all of it. keeping costs down. I will have to post machine the counter bores no biggy.. Not sure if I want to tap the "Bow-Tie" cross brace or drill a thru hole and use a ny-lock nut. I'm open for suggestions. Tony Quote Link to comment Share on other sites More sharing options...

tonyslongez Posted May 24, 2009 Author Share Posted May 24, 2009 Will this fit a Cozy as well? They may, I don't know to much about cozys. It wouldn't be hard to make the hinge wider if needed Would you be able to sell these? Yes I plan on selling these hinges. Alot of long Ez owners have shown interest in flip up style canopys, much like the Berkut. I have to make these hinges for my airplane anyway. I'll just make a bunch and sell them to others! 1 Quote Link to comment Share on other sites More sharing options...

Cozy Girrrl Posted May 26, 2009 Share Posted May 26, 2009 I was working on that in my sleep last night and woke up realizing I'd have done it out of 4130 tubing as a weldment. Probably lighter and stronger. I think you're going about it the right way, predictable results. Originally I had thought of doing it by welding several plates of aluminum together that had been cut at angles to achive a hinge approximating the original... heavy and not nearly as nice as what you have come up with. So what are you going to do for the gear? ...Chrissi Quote CG Products www.CozyGirrrl.com Cozy Mk-IV RG 13B Turbo Link to comment Share on other sites More sharing options...

tonyslongez Posted May 30, 2009 Author Share Posted May 30, 2009 Yup I agree. It's a shame too, they sure are nice gear legs, a bit heavier than I like to see but S.O.C.K.S. That's spanish for "That's what it is." Tony BTW! The aluminum for the molded aileron molds have arrived they are being welded as I'm typing this.

Looking forward to it, I never thought we'd be making chips to make plastic airplanes but I am not complaining at all..ok, just a little bit because we'd really like to work on our own plane!

Cozy Girrrl Posted May 30, 2009 Share Posted May 30, 2009 If you are selling your TIG? How you gonna make those spiffy engine mounts, or are they all being farmed out?Thats because we replaced it with an even better one Up until recently all welders were 60 Hz in, 60 Hz out. The next generation of inverter welders synthesize the A/C output so they can vary the output frequency as well. In the case of welding aluminum the high freq means that rather than radiating omnidirectionally it radiates more out the end of the electrode as if you were D/C welding steel, narrow focussed penetration. In fact you can sharpen the electrode as if it were for D/C welding steel. We have an application that needed this ability. It has a lot of other nifty features I look forward to playing with and the water chiller is much appreciated too No, we do not farm much out any more though we are outgrowing this house and barn and need to move the whole thing to a hanger, we are running out of space and available power. So, we do have a very nice, lightly used Lincoln Square Wave 175 Pro TIG available with cart and some accessories to a good home. Please somebody buy it so we can buy a hi-res CNC plasma cutter???

Personally I am not in favor of gluing parts on any engine in an aircraft, with the exception of composite airframes I do not like adhesives period, long term something is going to come apart unless there is a huge surface area and very little load. If they weld them on or thread them in then I'd feel better about P-ports. ...Chrissi Quote CG Products www.CozyGirrrl.com Cozy Mk-IV RG 13B Turbo Link to comment Share on other sites More sharing options...

He's all over the map.It was observed by reality based folks at SNF that He Who Shall Not Be Named has become something of a non-entity.Being able to pair up Tracy's ECU with the EFISM (Electronic Fuel Injection System Monitor) that we have been working on with Ed Anderson (Ed's the brains, we just make it look pretty) will make fine tuning the rotary much easier plus the added safety of a volume based fuel management/advisory system.
