Modern manufacturing for vintage autos

Both mirrors

Last year, I wrote about a case of 3D printed parts being used for a vintage car. This year, another fine example of modern manufacturing and prototyping techniques being used for a vintage vehicle showed up on my doorstep when my parents stopped by during a road trip in my dad’s 1934 Dodge Brothers pickup

Passenger side mirrors on cars and trucks used to be a luxury, add-on, or aftermarket item— if they were even available at all. My dad’s truck never had one. In the intervening years, many states have made side mirrors a requirement, and having them makes safely driving a vintage vehicle much easier. So how did he get the matching one you see in the picture above?

Passenger side mirror

He did what pretty much anyone can do these days: he had the driver side one 3D scanned, had a CAD model made up from the scan and then mirrored it. The model was then 3D printed and sand cast in aluminum. After some finishing work and paint, it looks fantastic.

However, geometry reared its head: it turns out that because the driver sits on one side of the car, a perfectly mirrored mirror mount doesn’t put the mirror in quite the right place. As a temporary fix, he added a standoff to correct the position of the mirror. After returning from the road trip, he’ll adjust the CAD model and have a new one printed and cast. Since the world of vintage cars is a close-knit one, he has already had requests for additional units from friends in the community, and making more will be straightforward from the digital master.

He’s had a few other components made using scanning and digital manufacturing techniques, including a laser cut insulation board for between the engine compartment and the cab. These techniques are a perfect fit for a community with low-volume needs for custom, unavailable, or never before made parts.

Highlights of Maker Faire NY

Giant handmade seven segment nixie clock

Maker Faire was a whirlwind of an experience, and here are a few highlights from our trip. Above is Wayne Strattman’s Nixie Rex, a giant scale handmade seven segment nixie clock. Each tube is about two feet tall. A “normal” sized nixie clock is on the table in front of it for scale.

This constellation quilt was made with glow in the dark thread by Haptic Lab.

Wall of Nails

Sometimes the simplest activities are the most satisfying. Contruction Kids let everyone leave their mark on Maker Faire by hammering into the wall of nails.

Power Racing

The Power Racing Series was joyfully providing great entertainment for the crowds.

Gertie the jumping robot

Gertie the robot’s creator Alonso is demonstrating with an oversized model how the frame inside the squishy case can move around to make her jump in different directions.

There were many memorable moments from Maker Faire, and the ones we managed to capture with our camera are in this flickr set.

Making Makers Book

AnnMarie Thomas has just released her book Making Makers: Kids, Tools, and the Future of Innovation. She interviewed many notable makers for this book, including Dean Kamen, Leah Buechley, Luz Rivas, and Nathan Seidle. I’m thrilled to be included in this group of fascinating people. It is available through Amazon for Kindle now, and paper copies are shipping September 25.

Truffles

With all the pumpkin spice jokes flowing around the internet recently, it’s time to remind everyone how easy it is to make your own pumpkin spice flavored things. Way back in 2007, we published a recipe for making your own pumpkin spice chocolate truffles (hint: no pumpkin involved) and you can use the spice blend on anything at all. (Pumpkin spice Raspberry Pi, anyone?)

From the mailbag: Bulbdial Clock Kit

Bruce B. wrote in to say:

I recently bought one of your Bulbdial clock kits. I just wanted to send a quick note to say that your step-by-step guide was the BEST guide I have ever seen, for anything. I have assembled many an item in my years and instruction sets vary from useless to marginally worthwhile. The Bulbdial guide was amazing! You should publish a step-by-step guide on how to write step-by-step guides :)
Oh, and the clock is amazing as well!
