As my recovery comes along and I get closer to getting life back to normal, I've felt the urge to mountain bike again. I've been out on some easy going rides this year while out camping and with the kids around town, but have not had a good hard ride since the TPMBC Spring Kicker (and the Tillsonburn4 a week prior). I sold my awesome RSD Sergeant to help pay some bills while injured and am left without a mountain bike.
As my body has been healing I've realized that maybe I gave up on the old fatbike too soon. I was empathetic to it. I felt as if I should have helped it recover from its own broken frame just as all the doctors and physiotherapists have been helping me recover from my fractured spine. I spent a good evening out in the shop staring at the dust and cobweb covered frame, reminiscing of all the good times we shared, before finally arriving at the conclusion that I should give it another chance.
I got to work stripping the pain from the frame and fork and fashioned a gusset from some plate steel. It wasn't long after that I fired up the torches and got to work brazing the frame. I felt right at home with the brazing torch in my hand while carefully doing the dance of heat and bronze. The smell of sizzling flux filled the shop while the gentle hiss of the torch played its melody in my ears. Fillet brazing is a bit of a lost art that I got good with years ago, but its just like riding a bike.... you never forget.
I added brass as I needed, carefully wetting out the puddle for maximum penetration. I didn't want to have this joint crack again and the plate I made is very heavy duty.
Brazing is a gentle process. You have to run the torch at low pressure to avoid blowing out the base material from too fast of a flame. The slow flame and quick wrist are what makes a good welder here. You need to be able to adjust on the fly and use your gut to know when to wick the torch away and prevent cooking the joint, and when to pour on the heat and lay in the brass. Experience is the greatest teacher when it comes to this type of welding, and you need to think one step ahead of where you are. There is nothing quite like it and it brings me a slice of inner peace during my rough injury recovery.
I finished off my joint rebuild and shut down the torches. I let the joint cool for 10 minutes before putting the joint into the dunk tank. The dunk tank is just warm water and will dissolve the glassy flux off of the steel. Without the dunk tank, the hardened flux is nearly impossible to chip off but will disappear overnight in water. Science Bitch!
Check back for Part 2 soon. This baby is going to need some paint and lots of parts!
