Fellows gear shaper manuals

[Oldwrench]

Mistakenly posted this in another thread. These are original good legible Fellows publications, not 4th generation photocopies. Machine is long gone and we were cleaning out a file cabinet in the toolroom. Yellow book is parts manual for the 7-type and a few of its variations. Smaller book is operator's manual for the 7 and 7A-type. Free to anybody who can use them.

If Mud can use these he should probably get them. If he passes I would like them.

Shipped to Mud already. I'm glad to find them a good home

Awesome! I didn't see the other thread

As soon as I have nothing urgent to do I'll scan you a copy. I promise.
I'd also like to find a 7A parts book if anyone has one to copy.

Testing file size

That scan is way too clean. You're supposed to smudge all the important info with greasy fingers and spill some coffee on half the pages, then scan it at low resolution with the pages crooked and out of order.

That's what I thought you were supposed to do based on most manual copies I've bought lately.

Ok, lemme work on it for a while.

Took me several tries to get all the pages right way up and the right way on the paper and the right file type. Other book is more complicated and bigger. I'll drag it through the shop first and let someone's dog have it for a toy.

Ops manual. It's a large file, 12K.

This is on the first page of the parts manual. Can anyone tell me what side-trimming is in this context? And spur and helical tooth clutches? Google is no help.

It must be talking about a dog clutch. Like synchro, slider or gear hub internal teeth in a stickshift transmission. Just a guess, but "side trimming" is probably the slight rake applied to the insides of the teeth so they stay together under power. I would think those parts are first cut as straight internal features on a gear shaper followed by multiple operations to cut the angles in the sides of the teeth and cut the angles on the leading edges of the teeth to smooth engagement.

I was talking to a guy about this recently. He worked for Warn winches in the 70's. Said the way they did this at Warn was to take any Fellows and build a riser for it, but get this- Build the riser on the desired taper.

I guess it's not an uncommon thing to do. I never would have thought to measure the riser for even thickness when looking at a Fellows. Could be a real nasty surprise if a guy didn't.

I've seen them for sale with an angled riser, that must be one of those models, never knew what that was for. The ones I saw were pretty obvious.
