I just put my storred CHNC back in service in my Barn Shop and I'm down to what i hope is one final proble and it's killing me to figure out. The spindle lock with not pull out and allow the spindle to move freely. Everything else on the machine seems to work and air to all air driven stations seem to work well. There is air going to the spindle lock and when I try to jog the spindle I can here it moving through the lines. I tried pulling out the spindle loce but could only get it so far so I stopped and lubbed it well with the hopes it might free up. What did i miss that might release the lock or is it just rust or moisture that is causing it to Jam in the locked postion?
