As soon as I discovered that they sell aftermarket shelix cutterheads for my Delta, and once I found a website where a guy showed the steps he took to put his in (convincing me that I wouldn't destroy my own jointer if *I* tried it)... well.... I just couldn't hold my wallet in my pocket anymore. I swear... it just sprang right out of my pocket when my guard was down.
Anyway, here's the page detailing the purchase and installation. I had it all installed in less than 2 hours. I'll post more about it as I get some quality time in with the thing.
