Jim, I own and operate a company called Carbon
Fiber Composites manufacturing airframe parts for the experimental
airplane market. I make composite airframe parts as well as welded
assemblies from thin wall 4130 Chrome Moly steel. Attached are some
photos of a recent project I completed for a customer. It is an interesting
weldment being both the engine and landing gear mount. The landing
gear socket tubes are a particular challenge due to the close fit
of the gear legs. Any distortion of the socket tubes makes installing
the gear very difficult. The top and bottom welds at the open ends
of the sockets are welded easily with the Cobra torch without
using filler rod. The welds toward the middle of the socket tubes
do produce some minor weld scale inside the sockets but absolutely
no distortion of the tubing allowing easy installation of the landing
gear. This assembly really takes a beating carrying the landing loads
of the airplane and several owners of these aircraft have developed
cracks in the gear truss. I've flown my homebuilt Wittman Tailwind
six years now and after a few thousand landings, there are no cracks
in the gear truss. Thanks for providing such an excellent product,
I use mine in my shop and make money doing it. It's the most versatile
tool I own!!!
