im getting ready to do the s1 tail mod on my m2. what method did you guys use to weld? i know tig is best, but just wondering if any of you backyard guys did it another way, i have a stick and a mig myself, and know a few tig welders. here is what i found in my searches You could MIG weld it using an ER80S-D2, or 4130, wire spool, and a C25 gas shield, but you would have to do a post weld heat treat to restore the correct toughness. The heat treat can he accomplished with a torch and a tempilstik heat sensitive crayon. Tempilstiks can be bought at most weld supply stores. You will want one in the 500 - 600 degree range. You heat the weld area gently. Every once and a while take a swipe at the weld area with the tempilstik. When the metal reaches the correct temperature the crayon will melt. Then allow the weld area to cool slowly by wrapping it is a thick wool blanket or some fiberglass insulation. Motorcycle frame tube is pretty thin, so any MIG will do, even a 110 volt machine should be able to handle it, but you will need to V-groove your joint a bit if you use a 110 volt MIG machine. With a larger machine no v-groove should be needed. |

I just had my left mirror support welded back on my Spider fairing on my S2 a couple days ago. He was using a MIG, but it's holding fine. Heck, it held with several good whacks with a hammer getting back in place too when it drew up a bit from the weld. (Message edited by phelan on July 28, 2008) |

I suggest you ask Jodie. He has a hybrid bike he built and has done lots of welding. He has a thread here with the build on it. |

couple of guys on this board have done that conversion. I'd used a 230v MIG if I could. the 110's power doesn't seem consistent and getting enough heat sometimes can be a problem-at least the one i was using. The tubing in that area is >1/8" thick so the more heat the better. The rest of your plan sounds good... |

Without seeing documentation I have to assume tube frame Buells are constructed of DOM and not 4130 as stated in the Old School masthead. The original frame welds are MIG'd and you'll be fine doing the same. I myself use ER70S-6 and straight Co2 with my Miller wire feeds,Lincolns seem to prefer mix gas. |

ill be using a lincoln handymig 110, if it will penetrate enough, i think it should, its held in several v8s in the local derby cars. any good place to get the er70s-6 |

ER70S-6 is available at any welding supply store for about $1.60- $2.00 a lb.depending on the spool size and your location. I buy 44lb. Ready Reels, the 110v Lincolns IIRC use 5 and 10 lb. spools. |
