Cool as penguins pee .. Love the intake trumpet 

Whats better about those oil tanks is when the bike is running, the feed at the bottom, the return will be at the top so you'll see all the action...

Awesome old Vincent .. 

That Vincent - i've got a feeling those cylinder barrels are not painted gold, but proper bronze cylinders. Marvelous.

C'mon guys, lets admit it.

2nd pic in - isn't that one of the most gorgeous and perfect motorcycles ever made. Ever seen.

All in proportion, nothing wrong.

If it were mine i'd swap the clip ons for straight bars, that's it.

Just absolutely stunningly beautiful.

I've always had a soft spot for the Rickman Metisse since first seeing them while working in a bike shop after school and at the weekends

Matisse are still going and they make the Steve McQueen Desert Racer...I'd love to get my hands on one

Nickel plated OIF (oil in the frame) chassis, great engines used - what's not to like?

We built a couple of Triumphs around S/H Metisse frames back in the day in my workshops, the frames and swing arms were just stunning, lightweight bits of kit. Welding (Sif-bronze on Reynolds 531 tubing) was a work of art.

BTW, brazing and braze welding are not the same. 

brazing and bronze welding are not the same.

There, fixed it for ya. ????

Ariel Atom is one that comes to mind.  I saw one at a local trade show near where they are manufactured in the USA plant and I could have driven it around the parking lot, but deferred. 

The V8 version ( originally developed from 2 Suzook engines ) is one of the fastest accelerating cars out there with a 0 - 60 in 2.4 sec's and one of a handful that can hold its own against the best superbikes in a drag ..

So it’s TIG welding with a bronze alloy rod?

No, flame from a gas torch, not a tig torch.

I'm not really the person to ask regarding the ins and outs of quality welding.

I'm crap at stick and can sorta look competent with a mig welder.

But tig is a relatively modern concept (70's on?), whereas bronze welding has been about since the 20's, and brazing even well before then.

It sure looks like TIG. It’s been around a long time in Aerospace.

Brazing - in the early days - was using an oxy acetylene flame and a copper/zinc rod. Modern times is a generic term for any welding using the gasses above.

GTAW - common name TIG - been around as said above since the 40's. In those days called Heliarc I believe

Gives you the most control, as the machine can adjust slope - how fast and how much the current increases and decreases - among other variables.

We welded beer cans together as an exercise. Altho aluminum requires an AC machine. Steel, etc uses DC

How daft and ignorant of me.

I'm now off to find some olive branches to beat myself with....

Thanx for putting the picture up and letting me know.

Reckon you gotta jump in the stinging nettles for that one Guzz' .. :smile:

Check the colour. Bronze.

Tig process replicates the old gas welding or Sif bronze welding.

Either way it sure is purdy.

Don't quote me, i may be wrong, but i believe the filler rod for tig is similar metal, not dis similar metal, ie alloy rod for alloy welding, stainless rod for stainless welding etc.

You can TIG with most any filler metal.

The advantage of TIG over oxyacetylene is better heat control resulting in less heat transfer.

We MIG weld galvanized with silicone-bronze wire as you can get a nice puddle with less heat and the weld doesn’t rust...

According to ESAB: Years ago, the process we now term ”braze welding” was commonly known as ”bronze-welding”. Ever since the process was renamed ”braze welding”, there has existed a degree of confusion between the terms ”brazing” and ”braze welding”.

Never been much of an ESAB fan. Had an Ultra-Graph trace cutter that was great, but the plasma unit was crap as was parts and service. Parts and service may have just been Thailand, but we went through two plasmas in two years with 50% downtime.

Looked kind of silly, but that Ultra-Graph was badass. 20 years old and still cutting perfect last time I saw it, only had to have the motor rewound once...
