---i just completed rebuild of my bp mill---it has a 2j head with vari-speed . i bought the similar book from the same author for the 2j model. i cannot say enough gooood things about this book. the steps are all numbered when you take the mill apart and reassem. same. the pictures are excellent. the parts drawings for my powerhead listed approx. 300 part no's. i used ''zip-lok'' bags to group items as i dissassembled. --lots of bags. when you go to check prices for rebuild parts you will find that they will vary ''all over the map''. charlie's advise is well taken---make some 'chips'' with your machine first--take some measurements --find out how accurate the machine will cut --before you dissassemble anything. whatever you decide to do ---have ''fun''. goodluck-- steve in montana
--in regards to the powerhead which is a little different than yours---i replaced all bearings with exception of the spindle bearings. the brake shoes and springs were replaced. the two drive belts were replaced . the wear bushings for the vari speed belt drive hubs were replaced. the drive motor was 1.5 hp.---someone had turned down output shaft .010'' undersize and made custom delron bushings for the vari-speed drive hub pulley. sooooo since it was worn out again i elected to go to another motor with correct size standard shaft and upsized to 2 hp. this allows later use of standard sized repair bushings, this however does not apply to your particular model. i also purchased new arbor press 2--ton model and made numerous bushings on my lathe to disassemble and reassem. the powerhead assem.. the book you purchased will guide you --it's really very very good. hope this helps, re steve in mont.
