W.E Sykes Gear Hobber Taper/step problem
(OP)
Hello,
Im currently trying to get a W.E. Sykes gear Hobber back in action and can get it to cut the required gears but it is cutting at a .005" taper/step.
I think I just need to offset one of the cutter heads but am unsure how to adjust it.
Im fairly a newbie to this machine so any advice would be appreciated.
Thanks

Are you sure you don't mean a gear shaper?
Sykes made herringbone shapers that used two opposed cutting heads.

You're right I meant that it was a herringbone gear shaper.
Im using it to cut helical gears but this taper/step is starting to annoy me lol
RE: W.E Sykes Gear Hobber Taper/step problem
I think I understand the 'taper' part but can't work out what you mean by "step".
Is the machine not cutting the correct helix angle or is it cutting a taper to the tooth form; where the tooth thickness changes over the length of the face width?

It seems to be that when the right cutter is cutting the right half of the gear, it isn't cutting as deep as the left (0.005" of a difference in root diameter from the right side to left)
Im sure that if I am able to adjust the right head, this should work.
Thanks
