nice one peter
started taking that drill to bits last night - its delightfully simple
its litterally 4 bearings a belt and a motor - real mans engineering.
everything is clean as a whistle inside and free to move. - the springs in tact i cant see any reason for the stickyness - how ever it is better sticky that the quill having rotational play imo.
going to grease it up and apply sewing machine oil to the gear from the arbor to the quill and get it wired up , its been suggested a combination of grease/oil and vibration from actual use will free it off.
as you said the quill certainly doesnt look bent when i lined it up on my straight edge.
how ever as a 1 man operation trying to get it into the garage and onto my bench i had to use the engine crane......
