FOUNDRY PATTERN MAKING part 2 Steam Engine metal casting tubalcain
This will be a multi part video on how to make a split foundry pattern . A wooden pattern is used to make an impression in the sand mold. A silica sand core is place in the mold produce the cylinder bore in the casting. The wooden pattern of the cylinder is turned on the Clausing lathe.

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.
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 again for making this series. I’m anxiously awaiting the next installment. I love all your videos, they are very informative
Very cool, i cant wait for the next video
Thanks great video.
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.
