WHOOSH .... is bad , I have been in the EAA for about 1000 years , used to
work for A/C manufacturing as certified welder , have had to do repairs on
covered planes , we just cut the cover away for 10 or 12 inches in every
direction and taped it fast , got some wet rags and packed every inch of
fabric with wet cloth , you really have to be aware of your torch and treat
it like a loaded gun , welding near fabric is not a solo job either, you
must have a extra man with an extinguisher and also a water hose under
pressure , it can and is done often , the newer TIG process does confine the
heat to a smaller area and less apt to have a disaster , good luck ..Phil L.

I'm an OxAy welder or rather, I can weld a nice bead on .035 4130 and
can jig up and build a cluster. But only on a workbench.

There is a wealth of practical knowledge that's not covered in the
books I have; for example, how do you weld on an aircraft while
retaining the fabric covering (think WHOOSH!!!!!)

Anyone found a book that goes past the basics and discusses practical
hint and kinks? - Mike
