Long name – simple function: Perfect 45º miters every time.
Some tools never die
I've been struggling to get my miter cuts perfect while making some picture frames. As you may already know, my workshop is small and powered only with solar electricity. This leaves me without my large (power hungry) table saw and my trusted crosscut miter sled jig – so high volume consistency and accuracy is difficult with a regular "miter" saw alone.
A friend of mine bought one of these machines a few years ago and I've wanted one ever since. They're not easy to find but as luck would have it, I found one on Craigslist only 150 miles away in Poughkeepsie, NY. They're a small fortune brand new at around $2700 so I think I did alright at $300 after a bit of haggling (which i love to do).
These machines are simple, heavy-duty, dust free, and noiseless. With very little moving parts, they last forever. I'm guessing this one has been around since the 60's? I'll probably hang onto it for another 50 years or so.
