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!

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

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.

Thanks David. I never knew about those...

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.

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

"Friction stir welding"

Speaking of friction welding, anyone remember the Spin Welder kits Mattel put out? Probably in the mid 70s.

I loved them as a kid. They really worked pretty well.

Re: Fuselage Welding

I have seen a few of those fail, we were tesing frictions stir welds at 6000 psi leakdown. Tim

Re: Fuselage Welding

Hi Mr. Finch

If you want a monster debate try the one on "can you really get a T-Craft on the step" or "is a downwind turn any more dangerous than an upwind turn". You might try the "I want hyd. brakes on my t-craft" or you can really set fire to the place by stating" well, I've dealt with the factory and got good service" better run and hide.

I am impressed by your shop and how refined your work appears to be, glad that you are with us.

Re: Fuselage Welding

Yah Dave, I've been following his advice for years.... seems to work for me. I think we're on the same page as Charles. Amazing what goes on sometimes. I'd still like to see a TC that says you have to gas weld, or the other reference made... ohwell, on with the show.
Charles, you shouldn't apologize for any debate, getting info out there is always a good thing, especially when you have the skills and experience to back it up! Thanks!
John

Re: Fuselage Welding

I apologize for creating the monster debate :boxing: on pre & post heat!

No apology needed Charlies, thanks for your input and advice.

The part that hurts my head is the anecdotal diversions and unsubstantiated claims.

Or maybe I am just having a bad day.

I'll follow the other Finch (Richard) and from what I hear you saying then it sounds like you and I are on the same page.

I have thirteen 337's for welding in 2009 and about 23 337's for 2010 all related to welding (getting ready for IA renewal).

So I have an interest in this type of information.

I have to do some work this week and perhaps afterward I can get a picture of the HAZ to show Tim and answer Tim's question.
