Well i finally bought Bryd's 20" shelix head for my Jet 4 post planer. All arrived well. I'm following through the instructions on the Byrd web site (written for a PM but seems that all these 4 post planers are the same design...pretty much). So as i work through this i'm sure i'd like some advise from others that have trodden down this path.
Main quesiton - i'm at the point where i should be able to "tap" the existing cutterhead out from the pulley side and remove it along with the gearbox. I'm a little gun-shy here. How much force should i use and is a deadblow hammer the right tool? I tried a hammer against a block of wood but stopped when it appeared to require more force than i felt comfortable with using.
A less important question that i've run into along the way...but moved on regardless.
step 6 talks about removing the gears
6. Remove the three bolts from the gears to expose the keys. It should be possible to rotate the cutterhead enough to align the keys in an upward position.
Not for me...i couldn't turn the gears at all and why does it say to rotate the cutterhead...these gears aren't connected with the cutterhead but the rollers that pull wood through. And why does it matter anyway as long as they stay in the same position?
