Earl,
I have a G1008 as well. I bought mine from my previous employer, I think it was made around 1985. There is a manual available at Grizzly.com you can download.
I have replaced the key that fits in the drive motor pulley a couple of times. The quill is tight at the beginning of the down stroke, hope to disasemble as soon as the weather warms up. Hope its nothing serious.
