I see a lot of talk of 3d printers... To join the discussion, I'd mention that they are technically "Rapid Prototypers", second to Digital protoyping as far as design flow goes. BIG $

When It comes to machining, I consider myself highly undereducated, so thanks!

I served in this mans Navy as a aviation structural mechanic, specializing in composites, and ultimately Non-destructive inspection. This is about the time that I run out of space... hehe

I swear, I will one day run a bronze foundry...

If the price of them come down to an affordable amount, a 3D printer would be great for making patterns. You could also make the pattern partially hollow inside and have the alignment pins and holes incorporated into the each half of the pattern like you see on the 2 fuselage halves of a plastic model airplane kit. Of course you would place the alignment pins so the halves fit only one way. Although, if you prefer, the old school way is fun and challenging.

@TinkeringJohn Speaking of 3D printers. There is a video on Utube about a machine that will print with sand to make sand molds. No pattern or cores are needed. So undercuts can be designed into the sand mold. I don't know what it cost in dollars but I have a feeling that it will cost many times over in jobs. Thats progress.

Hi. I worked as a wood Patternmaker for Dunlop Tyres. The Patternmaking industry has largely become automated and the old skills are becoming redundant. Obviously Tyres being round, a lot of the patterns we made were round and were lathe turned up to 7ft dia, anything bigger were produced on a Wadkin miller.

As a Journeyman Carpenter with years of experience I marvel at your versatility. Probably sounds like stroking but is actually material support.

Do you know if this trade is still pursued by industry or has it succumbed to outsourcing?

I imagine it is still possible to apprentice and pursue this as a career. Do Community Colleges/State Universities provide courses?

Thanks for the careful layout of the steps required.

Best and God Bless,

Jon

THANKS for your interest & nice comments. I suppose they still make patterns in shops around the country. I do know that Caterpillar closed their huge foundry & pattern shop in Mapleton, Illinois several years ago.

@psient Las Vegas, there is a carpenters Union, but every major casino has its own workshop to keep furniture in repair.

About how I had learned it my self. I love to see simple technique like this put to good use and presserved.

This is fascinating stuff. I love your detailed explanations because they are showing me that there is a reason and purpose for every detail, however insignificant it might seem, and how important those details are in achieving a finished product.

Thank you for doing these videos, they are educational and enjoyable.

Best Wishes,

Brendan

Once again, thanks for your efforts - good stuff !

Chances are your bandsaw blade is sharp, but may have a high tpi. To cut maple (or similar material) at that thickness you should have a blade with 3 tpi (teeth per inch) or less. A little canola oil (PAM in the grocery store) on the blade can also help.
