Re: Fuselage Welding

Friction stir welding by Mattel??? How did I miss that one? Apparently I was too busy vacu-forming with hot plastic to see that one......

Re: Fuselage Welding

The Spin Welder kits had a handpiece (gun with electric motor). You had a small white plastic welding rod that slipped over the motor shaft. The kits came with black plastic I beams of differnt lengths. When you squeezed the trigger, the motor spun the white plastic welding rod. Spinning the rod against the plastic beams melted and fused the parts together. You could actually make a bead. The kits also had rivets that spun on the same way to fasten panels (light printed poster board) to the frame. I had two versions of the kits: a dragster, and biplane. I don't know if there were any other kits. I wish I would have kept the parts and would love to have a set today but they weren't much fun once they were built and got thrown out long ago.

Thanks David. I never knew about those...

Re: Fuselage Welding

They still use the spin weld to make drill rod for the well drilling industry. The drill rods used for rotary drilling are hollow tubes welded to tool steel ends to cut the threads in to. The weld almost disappears and is considered the toughest/best way to make a drill rod.

Torch ???
Dam now I wonder why I bought that Linclon Tig more and more each day.
Does make a great stick welder for lawn mower maintance though.
Just wish Forrest would have told me that little tid mit several years ago. But in his defense he probably did tell me.

Re: Fuselage Welding

It's good to hear vour voice Norman, How have you been? How did this winter treat you? Are you working on your bird yet? Have you been able to get to the runway with something flyable yet?
Hey! Us real people want to know!

Re: Fuselage Welding

Good to hear your voice too Ron
Seems all I have been doing is working on this house since retirement. Got a hanger at the local Airport and am the airport flunky doing the mowing and repair work for hanger rental. Part time schoolbus driver and a 2 place Quicksilver on Ampibs . T is in my garge at home waiting till who knows when for me to fix the wings. Seems i have new spars and a crap load of ribs i bought from Eric years ago but this retirement thing and moving has taken its toll as i just now seem to be back on track minus the wall street hit and world affairs.. Been reading I now need new struts and $$$$$ to fix these things.
Anyway the Quicksiver is kind of a flying machine but it for sure is not a Taylocraft , but as the song goes "Love the One Your With".

BTW did I say I spend way too much time at Wal Mart Mcdonalds hanging out and I LOVE to hang out on my porch looking down the lake? As one of our member once said.
"You don't know Life till your sitting on your front porch eating and sipping tea with your plane floating on the lake 20 feet from you". In this case its a Quicksilver but its still mine! "LG" Life is Good. Better than some and not as good as others BUT still GOOD.

LOOKS like i need to edit my signature to include N 4NH Quicksilver on puddle Jumper floats. LOL

Norm,

I think when it gets to nine lines, it's considered more of a mini bio than a signature.

Re: Fuselage Welding

Norm,

One is just as good as the other. They both look fine. Are you going to the Taylorcraft fly-in this May?

Re: Fuselage Welding

So i feel the need to dig in here a bit. I am looking ata few projects coming up. I am asking for advice in torch tip size and technique for welding Exhaust, landing gear, oil sump.


Oil sump has a few cracks around the flange that let oil out. I had one or two of these fixed before. I imagine they fixed with tig or mig. it seems as though it was a bit brittle and between torquing up in this situation and vibration that i had these appear. my plan is to grind back the weld some from the inside and work my way around with a torch jumping from one side to the other to keep distortion to a minimum. then heat relieve whats left when done. then do a bit of penetrant inspection because i can at no cost as well as use it for a UT inspection test part again no cost.


The exhaust is something im going to build from ground up. I am not sure on material yet ss or not depends on what i can get ahold of easily. it will be tacked in place with mig. I could use mig here all the way around any dissenters in the crowd please let me know or PM me your thoughts. other wise I can use my gas setup. any suggested pressures and tip sizes ????

The next is an extended landing gear. YES YES i have a very qualified aircraft welder looking over my shoulder if needed(these welds will also be UT inspected since I will be sitting on them). This was an area that i planned on gas welding do to my ability to better control heat with it. I occasionally get out of rhythm with mig or tig (not much practice). Again filler material gas tip sizes and pressures rules of thumb?

If we don't want to stir any more up here I understand at least PM me what you know. ill post results as soon as these get done hoping to take a week off work and focus on these projects
