[Paul Williams] wrote in to tell us about his most recent and dangerous endeavor. Marriage.
As a masters student in Mechanical Engineering, he wanted to give his wife (to be) to be a completely unique engagement ring — but as you can imagine, custom engagement rings aren’t cheap. So he decided to learn how to make it himself.
During the learning process he kept good notes and has produced a most excellent Instructable explaining the entire process — How to make the tools you’ll need, using different techniques and common problems you might have. He even describes in detail how to make your own mini-kiln (complete with PID control), a vacuum chamber, a wax injector and even the process of centrifugal casting.
While soup can forges are probably the easiest to make, we love the simplicity and design of [Paul’s] Kiln — professional but on a budget.
He can’t take all the credit though, as [Wolfgar77] showed him the way.
Oh yeah, and after all the blood sweat and tears that went into the ring… She said yes.
