Sonoran Dave Posted May 18, 2017 Author Share Posted May 18, 2017 It may be closer to 5:1. It's basically a brick with wings Quote Link to comment Share on other sites More sharing options...
homefire Posted May 18, 2017 Share Posted May 18, 2017 The Mirage was pretty much all wing. A kite. Dead stick you had to give it at least 15% down or it could do the Leaf thing in the wind. Stall out and FLOP. 1 Quote Link to comment Share on other sites More sharing options...

Well in that case I guess a parachute is overkill, unless your in some heavy winds or your wings snap off!! The pilot did seem quite relieved after he touched down!! 1 Quote Link to comment Share on other sites More sharing options...

homefire Posted May 19, 2017 Share Posted May 19, 2017 (edited) I never had it happen but the guy I sold the plane to did about a month later. I think he used a bad mix. Edited May 19, 2017 by homefire Quote Link to comment Share on other sites More sharing options...

Sonoran Dave Posted May 20, 2017 Author Share Posted May 20, 2017 I started on the bungee struts yesterday. Got one strut end made before the drill press broke ? I needed one end thinner than the tube I made the strut from, so this how I narrowed the end without losing strength. I "milled" the end of the tubing with a hand grinder equipped with a flap wheel. Then cut and shaped two tabs to weld on the now flat faces of the tubing. Next, I drilled a 3/8 hole for a bushing and welded the bushing in place. After a bit of shaping with a flap wheel, the final step was welding a securing strap around the end of the whole assembly. It came out nice :-) Off to the hardware store for a drill press this morning... 2 Quote Link to comment Share on other sites More sharing options...

Sonoran Dave Posted May 20, 2017 Author Share Posted May 20, 2017 I'm learning all kinds of new stuff doing this project, but past fabrication experience is helping a lot in this stage. 1 Quote Link to comment Share on other sites More sharing options...
pairadiceau Posted May 21, 2017 Share Posted May 21, 2017 Looking great Dave, I have been doing some gas welding and brazing of late and find it a relaxing activity when everything is flowing right. Took a class many years ago so starting at ground zero pretty much. There is certainly a lot of good information online and on youtube. I am curious as to what tip you are using on that .040 material, filler rod diameter, and pressures you are running. Thanks for taking us all along for the ride.

Sonoran Dave Posted May 21, 2017 Author Share Posted May 21, 2017 Hi Jeff! Thanks for stopping in Gas welding is indeed a relaxing thing if everything is in tune and flowing well. I'm using a Smith AW1 so my tip sizes are different than standard Victor numbering. I believe a quick google search would yield a cross reference chart. Generally I use the #201 for the tiny stuff. I have an even smaller tip, a #20 but it rarely gets used. Maybe for welding sheet metal end to end. The #203 is my go to tip for most everything up to~ .062. I break out the #205 for bigger clusters or thicker sheet stock(.090). I did use a #207 for a couple of spots that had a significant heat sink and required more heat. Pressures I have been running are 8-10 psi on both tanks. The majority of the rod was 1/16 Tig filler rod. Alloy is ER 70-2. I did buy a lb of .045 filler and it has come in handy on the thinner items. Quote Link to comment Share on other sites More sharing options...
Old Tom Posted May 21, 2017 Share Posted May 21, 2017 Hey Dave, I have two drill presses lying idle for the time being. If you can't fix yours you are welcome to use either one of these. PM either Tom or me and we can arrange something. Old Tom 2 Quote Link to comment Share on other sites More sharing options...

Sonoran Dave Posted May 23, 2017 Author Share Posted May 23, 2017 Finished one of the bungee struts! I've been cutting extra parts as I go along, so the next one is mostly an assembly job Bungee material is wrapped around those horns with the spade shaped retainers, and the strut works by using the rubber to slow expansion of the strut. Kind of like a reverse spring. The last pic is hard to see because the shadows, but it'll give you an idea of how the geometry works. 2 Quote Link to comment Share on other sites More sharing options...
Sonoran Dave Posted May 28, 2017 Author Share Posted May 28, 2017 The Desert Eagle is finally sitting on its own legs! This has been the hardest part of the build so far. Everything has to be just so...or caster and camber get all out of whack. A lot of detail that pictures will never show and only a fellow builder will understand, but I'm happy with the results. Now I need to get real wheels and tires for it...those little hand truck tires are just for moving it around easily. 2 Quote Link to comment Share on other sites More sharing options...

When I was a kid there was an old air frame in this guy's back yard, it was of WWII era, but every time we were close by we had to go and take turns getting into the cockpit, and of course had to make airplane and machine guns sounds....vvaaarooom.... vvaaarooom...tat tat tat tat tat...tat tat tat tat tat... the Red Baron never had a chance with us in that cockpit!!! 1 Quote Link to comment Share on other sites More sharing options...
