The shop space(es) was(were) an embarassment of riches, but there were little things like empty tanks and voltage drop that kept things from being perfect. I ended up using the Hobart 140 and an angle grinder despite having a TIG and plasma cutter at my disposal.
The welds were fancy, not just tacks so there was considerable penetration. The mistake was to try and build up the weld so I could grind it off to look like a fillet braze. It will be a lot smoother with some work, but again I only had a few hours to get this far so I rushed the entire process.
Overall the process was very worthwhile IMO. The bike is definitely much quicker and feels much more balanced than it would have with just a fork and wheel swap.
