Progress isn’t glamorous.

It’s about showing up anyway, making mistakes, and trying again.

Those are the days that literally shape you. 🤘🏽

-Using a flexible shape pattern to mirror the left side fairing panel. I’ve found that flexible patterns are widely misunderstood so I wanted to spend a few minutes explaining what they are, what they are not, and how they can replace a buck. As for construction, they consist of a layer of low-stick tape that acts a release, and one or two layers of filament re-enforced tape. I learned about these from @proshaper , and Wray has a ton of content if you want to learn to make your own. When making a panel we need three fundamental pieces of information; Volume (shape), outline, and form. So let’s compare the information provided by this type of pattern versus a traditional paper pattern and buck:
-Flexible Pattern: Volume (shape), outline, contour gauge placement.
-Traditional Paper Pattern: outline, a map of shrink/stretch areas, contour gauge placement.
-Traditional Buck: Volume (Shape) and form. 
You can see how the traditional paper pattern combines with the buck to provide the volume, form, and outline. The flexible shape pattern gives volume and outline, but relies on contour gauges for the form. However even when using a buck, you often have to rely on contour gauges to get your form spot on due to limited visibility or abnormalities in the buck. Now the difficult part to explain in this format is how the flexible shape pattern shows where to shrink/stretch. You begin by adjusting form to get the pattern to fit as well as possible. If you pause the video at this step, you can see the edges of the pattern bunching against the panel. This would be equivalent to where you would have tucks in your traditional paper pattern, indicating a shrink area. As I shrink you can see the edges of the pattern fitting over the panel and becoming slightly loose. At this point it’s a matter of finding where there is space between the pattern and panel, indicating areas needing stretch. I prefer to do the bulk of stretch with the blocking hammer, smooth and fine tune to 95% on the power hammer, and finish on the planishing hammer. Once the pattern is fitting as tight as on the original panel, form is adjusted using contour gauges. **Continue in Comments

Laser welding sample from a few weeks back 

Over 43 blows to get the 3003 aluminum to split, and even then, it split beside the laser weld

.063" 3003 aluminum 

With a good fitup, the laser process is very fast and has very minimal cleanup/ distortion 

The TIG still has a place in coach building, as does traditional gas welding

Laser is just another tool in the shop to be as efficient as possible, in an industry that's built on attention to detail and craftsmanship
