I'm setting on a boat in the Gulf of Mexico, surveying for an offshore oil company. I don't have much to do for most of a 12 hr shift except read this forum. Like I said in my first post I'm about to start building a J3 with a Rotec R2800 on it. I've ordered the Wag Aero plans and the North Land CD with all of those neat drawing. I picked the J3 config 'cause I would like to be able to keep the empty wt under the 890 lbs allowed for a 115 HP engine under the ELSA rule (as I understand 'em) Want to go that route so I can operate it under a LSA ticket and fly without a doctor's permission, I aint sick but I don"t like doctors in general though they are alot more useful than lawyers. Like I said before I have put a 10% deposit on the R2800 and don't intend to spend much more 'till that little jewel is paid for and safe inside of my garage. To sort of get the ball rolling, so to speak, I believe I will go see if the Earle M. Jorgensen Company folks in Dallas (I heard about them here) will sell me enough 4130 for me to build some tail feathers. I was a welder a few decades ago before I found plumb bob beside the road and decided to find out what it was good for. I have a Heli Arc machine and an Oxy/Acetelene rig. I'm a little rusty with both of them. I've believe I could put a better weld on with the TIG but I read somewhere that it won't get the joint hot enough to normalize the metal and stress relieve it. The Legend Cub site has some pictures of them fabricating with a TIG but all of the other pictures of construction that I've looked at seem to be gas welded projects. Most of my questions in the first post I've found addressed in one forum or another in this fine web site; in fact I have just about doubled or maybe tripled my knowlege of Cubs by reading stuff here, but I dont find much talk about welding. Let me hear what some of y'all think.
