Bandsaw
Posted: 11 Aug 2016 20:31
After 15 years of cutting metal with a 4-1/2" angle grinder, I got tired of the noise, sparks, dust, and the jankety cuts I'd sometimes make. I needed a bandsaw.
But metal cutting bandsaws are, at least in searching Craigslist in the greater LA area, expensive, big, and run on 220V. Sure, there are horizontal bandsaws from China...but I didn't want a horizontal saw, or one from China. What to do?
There are lots of 14" Delta wood-cutting bandsaws around. They're fairly cheap. They're made in USA. You can still get parts for them. What's not to like? Well, stock, the blade speed is way too high to cut steel, and with metal saw blades ~$25 each, it's not like I can throw a saw blade at it every week. What to do?
There are a couple electrical solutions to this, but I chose to swap out the A/C motor that came with it for a DC motor from a treadmill. Anyone owning a 510 knows that something like this isn't quite as simple as it sounds.
So, first, my 14" Delta bandsaw. In nearly-new condition off CL for $225: Might as well get rid of the A/C motor first. This big, huge, heavy thing was rated at 1HP: Next I needed to be able to move the bandsaw around. It came with the 14ga steel enclosed base, but no wheels. Some 1" box tube, some casters, and a piece of diamond plate gave me the base: Then it was a matter of finding the right motor. Treadmills come in all shapes and sizes, as do the motors and controllers. I could drive around my neighborhood on trash day and probably come up with an entire treadmill for free, or just search local CL for people selling them for $50. So I did. But I didn't find what I wanted, which was a simple dial speed controller (potentiometer). Locally everyone seemed to have very fancy treadmills with a NASA-esque feel. Did not want.
Ebay turned up a guy who parts out treadmills for projects, and one of his auctions had exactly what I wanted. $150 later, it was at my door. Here's the motor controller and other bits. We'll get to the DC motor in a bit.
