I have an older Craftsman floor standing Drill Press. From pictures I have seen, I believe it to be a mid 70's model. I would like to re-build it and put in a new spindle, chuck, bearings, Etc. Is this something I can do or do I need to take it somewhere to have it re-built? It has all cast iron casing and weighs a ton so I really would not want to ship it somewhere? I do not have a manual so I really do not have part #'s and stuff. Would I need any special tools or can I take it apart in keep everything in sequence? just not sure what to expect? Also, the work table has to raised by hand after unclamping it. There is not a hand crank for it. Can I retro-fit it to a crank type system? Thanks, DonO
