Hello all! Nice little place you fellows have hee, I feel lucky to have found it! As the thread title states, I'm experiencing a problem with the idler pulley on my drill press. It's a Guardian Power drill press, model BDM16SS, 16 speeds, 3 five groove pulleys for speed adjustment. This machine was given to me by a friend after his dad passed away, I don't know it's history beyond that. It seems that the man was not prudent about maintainance. On any other machine of this type that I've ever seen, mthere needs to be two movable pulleys to allow the belts (2) to be moved to allow speed adjustment. On this machine, the motor is mounted on a carriage that can be swiveled inboard (closer to the idler) after releasing a latch. The quill is stationary, no provision for movement there. The idler pulley is mounted on a "dog-leg" arm that should allow it to swivel L-R to allow speed change. BUT, it doesn't. It's locked up tight right where it is. I've had a heat lamp on the outside of the casting for ten days now and have been spraying the shaft with PB Blaster six times daily in an effort to free it up, no joy as of yet. At this point I'm almost ready to take it to a local shop and have them cut the shaft off, bore out the hole oversize and install a sleeve to fit a new shaft. So I am appealing to you folks for help/inspiration! Anyone have any ideas how to loosen this shaft?
