Winter Bike Project . . .

Recommended Posts

The pneumatic versions are about twice what the foot pump ones are, and a lift is one hell of a nice bit of equipment in a shop that is for sure. Look around! I bet you can find one cheap. The bike is looking good btw, keep up the effort on the wiring, it will pay later (ask me how I know) haha

>>redyy/orange bits reddy/orange?
They are reder (man, did we just take "red" for a ride) than they look in that picky. There's also a small red bell on Nina. But that'll all be hard to see in the end. When the exhaust system is in place both the horn and battery hold-down will be covered. You might get a hint of red at certain angles. Just enough to be kinda trick, I hope. That's the plan anyway . . .

I was a firm believer in the pure essence of TIG for the important welds and anything aluminum or stainless. Lately I've come to see the work of some master coach builders who have been doing amazing welds with oxy/Ace in steel and aluminum...... but they put the time in to gain the skills and experience to make expert welds with simple equiptment.

That is who taught me....I am no where near their skills, but get by with my antique methods! (never mastered aluminum!)

Just outside of Vancouver, WA is a guy named Frank Springer; I just had lunch with his brother Lannie who I jumped with back in the '60's.

Frank is a local legend; he has built some amazing restorations and ( now in his '70's ) still has a waiting list of people wanting him to work on their cars.

He is one of the very few people who can shrink aluminum. :o

WAY back when...I was an inspector at a under construction Nuke plant.

When ever there was a weld to tough for anyone else to get, they would bring out this 70 year old cranky bastage that would scratch, spit & and lay tracks that NEVER failed...no cracks no inclusions...EVER! B|

He'd be in a corner standing on his head holding a mirror with one hand, he'd finish up & ..."check it kid, it's a good one" ...and then back to hide again in some cubby hole, without ever waiting for the results or even looking back. :D

Not a welder or a metalworker.

How does one shrink aluminum (or any metal for that matter)?

And what would it be done for?

My first thought would be for locking an outer piece around an inner piece.

Is it something like that, or something totally different?

for shaping and forming curves and such

I learn from men like him...But like a dumb ass...got wander lust,,,,and blew a chance to learn everything a master could teach me!

we live in that world now...a world where there are fewer and fewer men of mechanics/machines/metal...(I have no clue how to say what I am after) but "men that can fix whatever breaks"...(just spent my afternoon doing that on my sons mountain bike, ( Building parts It needed)

If a part isn't available, then "make it"

fuck my rambling, Jay Leno has written a lot on the subect and is much better with words, (and spelling) than me...

I am just very greatful for all the machinist/welders/fabricators that helped me out while coming up!

Shaping compound curves in sheet metal from flat sheet requires stretching some of the metal and shrinking it around the the edges. Stretching is "relatively" easy to do. Every time you ding metal you just stretched it. Shrinking requires gathering pleats and smashing them flat and smooth without re- stretching it. You can only do so much compound shapeing , for lack a better word, in one piece so its done in segments and welded together to form a classic car fender or custom chopper gas tank as examples then these segments are seamlessly welded together.

The true masters will weld these segments together with oxy/ ace to minimize the weld bead stress across a seam that may need further repeated shrinking or stretching and shaping. The weld area behaves just like the rest of the sheet while being worked.

Other weld techniques would fail with further shapeing and re-shapeing of the sheet metal.

Sheet metal can be shrunk by gathering pleats or tucks and smoothly smashing the down and by various methods of thermal shrinking with torches or friction discs and quenching with cool water but there is still a lot of hammer techniqe involved.

I'm referring to sheet metal work. For the thicker work of pipe fitting TIG roots and stick passes are still the norm.

As mentioned, when you 'work' any metal it becomes thinner and grows in size. To get it back to a 'normal' you have to shrink it. If you are very, very good ( and there are not many who are ), you use just the perfect amount of heat. Heat will shrink the metal. And it is far harder to do it properly with a metal such as aluminum.

That is why Frank is so well thought of in the N/W car restoration circles and why he has a large waiting list of people who want only him to work on their cars.

Bodymen who are true metal workers are few and far between these days of just putting a new part on and 'There you go.'

Now back to your regular programming: How's it going Nick?

Thanks for the very clear and detailed reply.

That's one of the things that is so cool about this site (and the sport).
So many different people and backgrounds and experiences.

And a willingness to share them:)

>>How's it going Nick?
This photo was taken yesterday afternoon. I was hoping to get far enough in the wiring to bump Nina's motor over. But once I started routing and hiding the wires I kept losing the big picture. But it's more complete now. I've got the fuel tanks back on (the only way to get the ignition switch setup) and only have to hook up the handlebar switches.

Running the wire bundles up downtubes and across backbones is sort of tricky. Wiring is mostly easy when you can do it one wire at a time. But I'm thrusting five and six wires at a time up, down, and across the frame tubes and hoping to hell I don't meet a wire needing to go the opposite way . . .
