I agree completely. No one way is better than the other, only the technique that the framebuilder is most comfortable with is best. Personally, I don't pin frames, I tack them. Works for me. Curt Goodrich Minneapolis, MN

each of my frames has 18 pins through the various joints. why 18? perhaps it's an hommage to my jewish roots; the number '18' is the symbol for 'life', chai... 18 is also the number of pins i need to keep things from going awry while the frame is fixtured, since i don't braze or tack in said fixture. in my opinion, one way is no better than another way. but don't mis-read this; my 'way' is better for me than if i were to use 'his' way in my working environment and with my tools 'n materials. pinning and tack brazing essentially do the exact same thing-to allow a frame to be 'extracted' from a fixture and brazed, free-hand, so that all the expansion and contraction from the joining process can allow the pipes to 'go' where they want to go. just as a plant grows toward the sun, heat affects metal. the idea is to 'tame' the metal to react in a way that enhances the finished frame, rather than detract from it. as with everything, it's an economic issue; if it matters, and if you can spend the time, you do it, if it doesn't matter, you find a more time/cost efficient way to do it as well as you're able to do it. economics... e-RICHIE* chester, ct *pronounced 'itchy', the 'r' is silent
