Dyad1: Check out the chart that Have Blue provided ( Thank you, Have Blue, that is a very important chart)they refer to a " Spindle driver, remove plug and lube with 20 wt."
Some Tree models, and some upgraded bearing sets use an open bearing for the spindle, or possibly shielded , I have seen both. When you remove the small pipe plug right in front of the guill, by putting lube ( 20 wt ) it will lube the 4 spindle drivers and the spindle bearings.(If they are not the sealed type )
If you do not have a parts book for your machine, call 3 s at 414-570-9530, and ask them for a parts book. The parts book has the lube locations in the front of the book.
When I retrofitted my Tree Mill to 3 axis CNC, I hooked the 2 quill oil locations to a manual Bijur pump I bought from ENCO..pretty cheap and it works, that way I should never hear that terrible screech of a ruined spindle, and the spindle drivers are always lubed.( the little spindle drivers and 2 axels are just really pricey also)
Hopes this helps, E mail me if you still have questions.
