If you intend to build smaller burner later on, that could make sense. You could also fill the orifice of a MIG tip with solder, and drill out a smaller hole through a lot softer material. What works out easyest in the situation is what I recommended; that will depend on the tools you have available. 

All cylinder-mount Propane torches are exposed to full cylinder pressure; most of them modify flow with needle valves; this does NOT modify that pressure. Thus, their gas jets are designed to run at extremely high pressure. When we look to make end runs around limitations, we must use the techniques we find available.

Thanks, I went the solder route as I had that as well as a # 70 drill and pin vice. I held the drill bit with insulation from telephone wire.

I am working on reducing my accelerator orifice for a 1/2" Mikey burner.  I am thinking of buying capillary tube from Ziggy's with OD of .064" and ID or .020" and then drilling out to .028" with # 70 drill (.028").  What do you think? Thanks. Karl
