Converting A Basic Taiwanese Drill Press To Vfd Controlled Beauty

[Nammar]

Dear Techie1961,

What a great restoration job. The machine is now better than new. I have the same machine in my workshop at home, which works, but niggles the hell out of me when using it, as the light does not work (something wrong with the light fitting) and the belt tensioning levers inside the casting are disconnected and every time I want to change belt positions, I have to get the crowbar to re-tension the belts. Otherwise, the machine seems to be well made and is quite sturdy. Not like old iron, though.

While you had the spindle out, did you renew the bearings, or did you just leave them? Geoffrey.

Thanks Nammar! It was an annoying drill press for me also; never the right speed and it vibrated a lot. When I had it apart, I changed the spindle bearings and if I recall correctly, they were 6204 (maybe 6205) bearings in the spindle and the top driven pulley were definitely 6204. You can see them to the left of the housing in this photo.
