We started cage work for a vintage racer 914-6...
Customer brought in a decent stripped tub, fitted for a complete fiberglass fender setup.

does pre heating help? Yes. No problemo. I'm note sure they still do this but NASCAR I think used to require the cages be placed in an oven after welding to be cycled up in heat and slow cooled to naturalize the cage. It doesn't take alot of heat I don't think. (can't remember all the little details it's been awhile..) But a rosebud with a low flame moving over and away from the joint several inches should accomplish a nice slow cooling cycle. IIRC it doesn't even have to be red or cherry, just heated and not overheated. There should be alot of info on the airframe builders forums. I always gas weld 4130. There is a specific filler rod for 4130. I have some in the garage. Can't remember the part number. Sorry for the hi-jack (IMG:style_emoticons/default/wacko.gif) I tend to ramble. Hopefully some of this dribble will be useful.. (IMG:style_emoticons/default/smile.gif) |
