Serge asks- >If I buy strips of 4130 steel of the correct thickness from Aircraft >Spruce, can I use them as they are to make WAFs, or is there any >treatment (other that surface treatment) that I must apply?
There used to be a very informative webpage from Dr. Dean on this subject, later linked to the Area51 webpage where WAFs were being offered for sale. I seem to recall that the information indicated that it isn't as easy as just cutting the WAFs out, drilling the holes, and cleaning up the edges. Not much help, I know, but unless you're waterjet cutting (or other method that doesn't heat up the metal as you drill or cut), there is something else required to ensure that the fittings retain the strength needed in the area of the holes. Anybody have that information? Oscar Zuniga San Antonio, TX mailto: taildr...@hotmail.com website at http://www.flysquirrel.net
