Here is a link to another of matronics sites that have had a lively discussion on this very matter. You will have to go thruogh the archives to find all the feedback. Ben Haas.

Should the string be streached from the 3rd rivet at the end of the sparof each wing or should the string extend from the physical end of the wing tips?

If you have a digital inclinometer it works out to 2.375 degrees. Set the digital readout square on top of the main spar and it will flicker between 2.3 and 2.4 degrees. That way you know it is reading just under 2.4 degrees. Also most of us have found that on initial mounting of the wings they are forward swept and need to be layed back 1 inch or so to get them square with the fuselage centerline. If I had to do mine over again I would have left it in a forward swept position to get the CG to work out better. Seems that even by staying under the 440 lbs firewall forward weight on the powerplant it takes a lot of lead in the tailcone to get within range. If you have Yahoo Messenger loaded in your computer there are a dozen of us you can instant message all the time to share our building experiences with and swap ideas. I am both, stol83001 and n801bh in Yahoo Messenger. It is a free download to get it and once you contact any one of us we can put you on our builders list and that will give you all the others names.

First what machine did you buy? I have a Miller in my shop at work and a Lincoln in my hanger here at the house. The big difference is that the Miller gets quite unstable at amps below 30. The Lincoln goes down to 5amps with good stability. If you are planning to weld Al. you first should know that when you Tig Al. there is a coating on the metal that you just can't clean off. You have to hit it with extra heat and as soon as you see the coating(look close when starting and you will see a layer burn off)get off the heat or you will burn thru. If you have a machine like one of mine say 180 amps the Tung. size should never be over 1/8. I use 3/32 most of the time. Al.is hard to enough to weld so just clean,clean,clean,and clean again. Get yourself a Stainless Steel brush and keep it just for cleaning Al. If you want to start with steel get some 16ga and practice on it.Heat setting should be 50amps or so. They make all different types of Tung. but all I use is Red or Green Any other help you need feel free to write me. By the way I have been in welding and fabrication for 30 years. The last 26 has been as the Senior welder at the St.Louis Zoo here in St. Louis. I am building a 701 from plans...............Bo Jari Kaija wrote: --> Zenith-List message posted by: "Jari Kaija" Just bought used TIG welding machine: http://www.jarikaija.com/pub/kemppi_tu20.jpg I would be more than happy, if you have any tricks, resources and advices about TIG-welding... and ofcourse, FOR FREE!

They don't look too bad for starters. Listen what I find with tig is don't be afraid. Just get in there ,breath regular,always try to rest your torch hand on something . Your speed looks ok ,your heat setting looks alittle hot. Weld is abit too flat..From your picture I would run it right to left with my torch pointed in direction of travel about 30 deg. off horizontal Jari Kaija wrote: --> Zenith-List message posted by: "Jari Kaija" Just bought used TIG welding machine: http://www.jarikaija.com/pub/kemppi_tu20.jpg I would be more than happy, if you have any tricks, resources and advices about TIG-welding... and ofcourse, FOR FREE!
