I started messing with things tonight after family went to sleep. I live about a mile from my shop, so I can sneak down here quick. With the knee not moving, I pulled off the felt wiper cover, it's cracked: has been over tightened. And the wiper itself is dead. No surprise there. The flathead adjustment screw on the gib is SEIZED. I filled the hole with wd-40 and in about 7-8 seconds it's gone, so it's going somewhere, hopefully that's a good sign. I'm going to let it soak overnight, then in the morning, I'll put my hand impact driver on it for 1 hit and see what she says. I talked to my buddy and he seemed to have a memory that this was a 1 part machine, so he actually never moved the knee the whole time he ran it... So he said it's been probably 15 years since this knee has moved.
I chipped the metal chips out of the T-slots tonight (flat blade screw driver and a hammer)... They were packed. The t slots were completely full. Now those are out and I started cleaning the table a bit. It's in great shape. I'll clean it up a bit more tomorrow in the light and take pics.
I plugged in the computer that came with this thing, and it works! Hahaha. Didn't expect that. I plugged it into my flat-screen I use for my security cameras, and the dang thing works. I figured you guys would get a kick out of this. On the screen, the jogs work, and I loaded a program the shop ran, and it ran through all the numbers in their g-code. Haha. I'm just watching it sitting here laughing. When the mill can get the right power to it (it's in my forklift shed right now), I'll plug the computer in and see if this thing will move it. Check out this computer and the DOS program...
