Cutting shafts

[Kim Bye]

There is one thing you must remember........... every machine has a frequency that will result in a harmonic vibration that will give a rough cut.......... the frequency is created by the cutter... is it sharp? how many teeth does it have?... are the gibs tight and lubricated?.. feed rate....... RPM..... how you drive it..... your router mount..... the belt on your motor..... the material you are cutting.......... depth of cut.... router bearings.... live center bearings..... etc


it may take some experimenting to find your best setup.............

That's a good point, harmonic resonance can be a huge problem. I put my taper shaper on vibration dampening feet, that helped alot.

hahaha......... I didn't want to mention it but........... I have a big rubber block C clamped to my router mount to dampen vibrations......... makes for a smoother cut.........
