Thanks for all the great advise. I am planning to get a plastic tote that will fit in there to catch the chips.
You can see in my picture that this machine has a dead center to go into the end of the hob arbor. The center and the adjusting handwheel will come out and inside is a bronze bushing for running on the hob arbor. Sort of like the ones on horizontal milling machines. My question is would it be better to run the hob arbor in this bushing or use the center? I realize that this center would be much faster to change the gears that you are hobbing but I am wondering if using the bushing would be more rigid. Also what type of oil should be used to lubricate all the cups on this machine? I am using way oil so far.
