Hi. This is my first post here. Recently, I decided I was going to build a single speed cross frame, and I have tons of questions

I read a book telling me to use MAPP gas, but it does not seem ideal. At my old job at the dental lab, I used an oxygen-propane setup to melt metals for crown and bridge frameworks which I still have access to. To have a flame with a consistent temperature every time, I would limit the pressure on the oxygen regulator. I light up the propane, turn up the oxygen all the way till it hits the limit, and then turn back the propane until I had my desired flame size.

Does anyone know if this setup would work well? If so, what pressure should I limit the oxygen to for silver brazing, is there a formula or online calculator anywhere based on flame temp. Being a mechanical engineer, i should know this, but I don't feel like digging up my thermo book.
