In preparation for doing some simple OA welding on a rudder, I've been practicing on some 4130 scrap. Since there is filler where it's not structurally important, I"ve been filing the excess material. All except one and it's as hard as if I were trying to file stainless. Is this an indication that...

Maybe I am spoiled. I keep expecting that in this modern age there will be plenty of photos of an event like AirVenture even while it is ongoing.

Can anyone tell me how similar these engines were to the Merlin? I know they were a derivative but being intended for ground use may be so totally different as to be useless for any aviation application. Why do I ask? An acquaintance has just acquired a complete Meteor engine and is looking to...

I want use my home workshop to rebuild an old, junked restroom from a USAF DC9. The milspec drawings show a slot for "used razor blades". How often am I supposed to clean out the used razor blades to maintain airworthiness specs?

Let me change that from "any thoughts" to "any helpful" thoughts G. "Dick" wrote in message ... Staring at my empty instrument panel while considering which instruments and their placement, I got wondering how old...
