the Power of Functional Design

I love old tools. This lathe came from my grandfather’s attic, and it’s probably about three times my age. It was made in a time when things were meant to work, and work well. You bought a lathe (or a sewing machine, or an iron, or a mixer) because it would indeed simplify your life. If a product worked well, it meant less time spent maintaining the equipment, and more time using it. If a product was simple in function, it was easily adaptable to different needs.

This is a motor with a leather drive belt leading to a simple spindle and X-Y jig. Some would consider it crude. I consider it to be a flexible, robust product designed with the end-user in mind. Here’s why I think so…

It’s simple. To anyone with the slightest idea for what a lathe is and how to use it, the operation of this machine is dead-obvious. There are no switches are dials, no abstractions between what the user wants, and what he gets.

The transmission is a belt on a wheel. Move the belt to a different wheel to change the speed. It might not be as “elegant” as throwing a switch, but it’s dead-obvious operation, and it’s very easy to diagnose problems when they arise. If the machine stalls because of belt slippage, it’s obvious.

There are no power switches or complicated power supplies here. The mains lead directly into the motor, and that’s-that. Why? Because switches are the first thing to break with time. When the switch wears out on a modern tool, the user throws out the product because it’s too difficult to swap out and integral switch. This product relies on external switches like a light switch on the outlet. That way when problems arise, the user can easily understand and diagnose the issue, fix it, and move on.

This kind of thinking is why this lathe, fourty years my senior, still works as well as it did when it was brand new. Lets see what our “modern” power tools look like in 2066. They’ll all be in landfills, but this one will still be going strong.
