what about some cheap updates of the zombie plane? interesting build Muscle... g2g, I need a hot dog... or two, with extra bacon, and a lot of tomato and onion, ham, ketchup, mayo... and chili... extra spicy... update the plane muscle!

Time for an update. After about 12 hours of disassembly, got the fuselage hauled down to the blaster for some cleaning. Between old bad repairs and corrosion, I have alot of welding in my future.

Oh yeah buddy!

Yesterday while wasting some time - I searched Youtube for some tips on TIG welding aluminum... I came across some "interesting welding" - one of which showed a guy using a torch on the bottom of a beer can - and then doing a technique that "back in the day" I'd have called brazing... adding filler and smearing this filler around until the hole was patched.

Looks like the repairs here used a similar technique... :lol: :thumbsup:

I'm ASSuming that the airframe is aluminum?? I don't know anything about planes except that I'd never jump out of a perfectly good one.

Just another question on this kind of repair... If you cut the tubing out - will you simply butt weld in a new tube? Or will you insert some backing into the tube first and then butt weld it. Not sure that you'd call that - but it's like the reverse of fish plating something if you know what I mean?

Yeah....I don't like those kinds of pictures. :_paranoid

And that sucka flew around like that.

The frame is steel and many have linseed oil inside to prevent corrosion. As far as the correct repair, I'm not sure if its a spliced in section of tubing or tube inside tube, its been way to long since I went to school.

Oh, linseed oil is flammable, burning through a cluster weld will scare the crap out of you.

Think of it as one big roll cage. Repairs are allowed, I prefer to replace entire tubes were able. Splices are allowed but there are rules as to where and how you do them. Tubing is mild steel 1020 except in structural areas where it is 4130. All repairs are done with 4130 and gas welded. I do not like to TIG fuselages as I still have to preheat and post heat to prevent embrittlement in the welded area. I will show some of the repairs once I get to somw of them. Some will be easy, others will be complicated.
