Tonight I´ve started cutting out templates for frame strengthening plates in 3mm steel, the steering head will need three of them to aid the welds so I won´t drop the forks at speed...  The rear axle mount also got a pair of plates.  I started triangulating the rear of the frame when my littlest girl yelled on the Babywatch and I had to call it a night. That radio is worth its weight in gold for sure, countless late hours in the workshop that couldn´t have been done without it.  Cheers! /Anders |

Tonight I finished making the templates for the 3mm sheet metal gussets (learned that word from a landracing guy who emailed me about how I should place them) so this week I will cut them out at work.  I added a pair of CrMo tubes just below where the seat will be to lighten the load on the weld where the single upper frame tube ends.  At his point I removed the engine to see if any of the tubes would be in the way, they weren´t so I continued by removing the oil and kero tanks and air intake so I could add a couple of strengthening tubes between the lower frame tubes.  Here you can see them a bit clearer.  The biggest progress tonight is probably that I think I have figured out how to make the seat and the rear fairing for the bike, I won´t tell you in case I change my mind but if it works it should look pretty good. Cheers! /Anders |

Last night I spent three hours welding the gussets to the frame, I also removed the two thin bars between the lower frame tubes and replaced them with 1 1/2" CrMo tubes just like the rest of the frame for extra strenght.     Cheers! /Anders |

Do you TIG because of personal preference or is it just the right technique for the job(s)?

When it comes to welding, I have found the found the following to be 100% true
TIG - Hyper-extreme precision regarding heat, penetration, filler deposition - Typically the most elegant and operator intensive approach
MIG - Throw lots of metal and heat at it to make it never come apart ever again - The biggest hammer in the shed approach
Stick - Like MIG but now with your hand 20cm or so away from the weld, you look like a conductor for the world's brightest orchestra
Oxy-Fuel - Like TIG but old school - Now you get to hang with the gray beards
Direct Short Spot Welding - This is why they say to never short out a car battery
Capacitive Discharge Spot Welding - Like sex, once you get her held down the process is relatively quick and then you need to recharge
I have more but they are for welding processes we probably won't ever see someone on this board use...

basically, if you can't TIG it, it's not worth welding  |

I'm juuuust getting to the stage where I can reliably get the roll-of-pennies look and good penetration at the same time. Stick welding just scares me, so much splatter! |

LOL.........as the owner of a grey beard , I love oxy welding sheet steel , no sticking electrodes or ulta violet radiation , just heat and watch the metal flow together , theres something very primal about using flames to do a job :-)
Cheers

I bought mine from a local turbocharger repair shop.
