Les and others....from my recent research I have learned you are correct.4130 is a great choice because of it's strength and ease of welding. 4140 is strongerbut forget about welding it.For my purposes 4140 will work great because I only need it for brackets that willnot require welding.By the way... I just re-worked my drawings from emachineshop.com and the totalto laser cut all my wing attach parts is $110. I can't buy all the steel forthat price!!!I'm placing my order this week.DJ Veghwww.imagedv.com/aircamperN74DV ----- Original Message -----
