Hi everybody - I am wondering if anybody has a set of the aluminum cast hinges (Vi Kepler - Ibelieve) for the tail feathers. I am debating what type of hinges to used (debating if I want to make my own ornot) and I was wondering if there are even any of those cast alum. hinges available.ThanksAndyRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Steel

Hi, Here's a question which I'm sure will be controversial (sorry...)I'm getting ready to start making/welding my metal fittings for the control assemblyand landing gear. I was all set to order a bunch of 4130 steel sheet/tube - until I started readingabout welding 4130... Apparently it is quite sensitive to sudden heating/cooling- (i.e. what happens in welding)I am very experienced with mig welding but have limited experience with gas welding.>From my understanding mig welding 4130 can be very tricky. As I started to research this issue I came across an experienced Piet builder (built/flew3 piets) who used mild steel (I'm assuming 1018 mild/cold rolled).He argued that the original Piets were designed/built by Bernie Pietenpol usingmild steel and so it is completely adequate (and the fittings are designed towork with the strength of mild steel). I know I can safely weld mild steel with mig - so I'm wondering if I should justuse mild steel.On the other hand I could go with 4130 which would presumably make my plane safer(technically stronger). However, if welded improperly (or heated/cooled improperly)I could actually end up with fittings that are weaker than properly weldedmild steel. I do have limited access to an oxy/acetylene welder and I could take a sport-airclass on aircraft welding - if that is absolutely the best option I'll justhave to get the gas welding skills (or get someone to weld for me) - I guess I'm looking for some help thinking this through - Is anyone else building with mild steel? Is anyone using mig to weld 4130? Thanks (and sorry for the lengthy question)Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________
