Frame forum will be like that scene in Bedazzled where the moment Dudley Moore gets in among the leaping nuns he will be blowing the raspberry to get back out.

"PP, gas welding doesn`t get cheaper than fillet brazing , does it? Just wondering."

Well yes and yes. I mean I assume he didn't have a gas rig, and if he had he probably would be fillet brazing it in which case all would be well for him, and I take your point.

On the other hand, let's just say he actually wants to weld the joint, possibly because that is his skill set, then gas is probably his cheapest realistic option.

And, gas welding is cheaper for several reasons: Start up wise the Mecco torch is cheaper (can be any torch one wants), and one either doesn't need but one tip, and it is also cheaper if one wants more than one tip. One doesn't have to source flux, or use flux which saves money on the flux, a bin to soak frames in, wear and tear on the shop floor and lungs. One uses a lot less filler and it is a lot cheaper. One uses a lot less gas.

To me the biggest cost savings, both as a small shop guy and an out of the US guy is that there is no access to quality bike brazing stuff up here. Sourcing from the US would be no problem for anyone with a serious interest in the biz etc... I get all my stuff from the US for my various hobbies. But stuff like this is kinda expensive to source on small orders, and there is usually an expense to breaking in new suppliers. Every one has a different shipping policy and shipping is increasingly expensive figure the same as the stuff one is ordering. And it won't be overnight, more like over-week to over-month. Compared to just buying a few steel rods from the local welding supply... Of course if you live in the US ... never mind...
