Hey Keith, I've got that #5 in old stock, I've only got the one but your welcome to use it.
I knew it - I was about to post that somebody here would have one. And here you are! I feel validated.
For all of the gears you do you need to rescue an old gear hobber. That would give you a chance to collect a whole other set of tools.
and think of the videos!!!
Yep, and get a much more accurate result too.
Harvesting duplicates for material? Brilliant and OH SO AMERICAN. Use everything you have. Suddenly all that 'dead iron' comes to life and is reborn as new tools! That's damn magic. Thanks Keith, good video! I'm always amazed to watch something like that! The battle of hardness in real time is really mezmerizing. I worked in materials science in my youth and fully understand the mechanical madness going on at that cutting edge!!
The part when he was machining off the teeth, I felt that all over.
Always a pleasure watching you work
Boy are you right about never having the right size cutters! I have a large selection, from 5" diameter roughing cutters to tiny watchmaker's wheel cutters, but I never have the size I need! (I don't cut that many gears, and have designed projects around the cutters I DO have, but still...) Finally bought a set of chinese 16P cutters for the last project. They worked fine.
Murphy's Mechanics Law: If one needs four identical bolts, there will only be three in that bin.
Yes, very common in my shop
Heyy!!... us Murphys getting the blame again!! 😂
@@raymurphy9749 If the shoe fits...
You probably won't find the matching shoe. lol
I just found an old, really old #5! Its an old National made in Rochester Michigan, but never used before. Dont feel bad, I have three of these. Email me your addrees, and Ill get it to you!

Shop law - you NEVER have the cutter you need 😁
The parallel in the woodworking shop is: _You never have enough clamps_
@@EngineeringVignettes not enough clamps on the planet 😁
@@mayshack John Heinz or Mattias Wandel? They have both made wooden clamps in the past... It could well be someone else though...
Dentist eyes would light up thinking about all those inserts he would be using LOL
Come on Keith I love your videos but I can’t wait to see the planer start making chips sir.
Being in a similar situation with a New Haven No 6 1/2, I am very much looking forward to the next video to see the whole process. I haven't been able to find any gears or parts for it, on ebay at least. I don't think they were as popular. Can't wait!
Good morning Keith
The epitome of interrupted cuts.
Looking forward to the next steps
Keep up the good work Keith. Long or short love the videos.
I feel your pain. When i had my garage a customer ask if I would reassemble some items his son had taken off his car and lost interest. When the car arrived it was 1968 Camaro taken completely apart. No suspension, no engine, no trans, no window regulators, no wiring. 100 percent dissassembled. There were over a hundred cardboard boxes of parts. It took a few months but got done
that's one tough insert there!
YAYUZ!! that buzzing sounded pretty darn angry!
Good job kind Sir.
Shopcat spotted at 4:16 !
Stealth appearance by Ginger!
Ginger
Well spotted!!
Yes, well spotted! I was distracted by watching the indicator. Thanks for the heads up!
There she is! Missed her first time around.
That’s always fun the watch . Thanks Keith
Nice to see some recycling Keith...
Thanks for sharing !!!
THANK YOU...for sharing. Enjoyed.
Human psychology sometimes has us count the misses and ignore the hits.
You can run 50 jobs with the correct involute cutters, but we only remember the times when we don't have the right one.
Not a problem for every day conversation. We all feel your frustration, and we get it.
But that's why we use real science and statistics when measuring important things.
It eliminates our natural biases.
Just my ramblings for today. Keep up the good work, Keith !!
This just means that you need to complete the planer so you can cut any type of gear on it... there was a guy who made an apparatus that would cut involute gears on his shaper with just a parting blade.
Thank you Sir. Good information well prepared and expertly presented. Cws & Anita
Good afternoon from St John Parish, Louisiana 22 Jan 21.
The advantage of using the old-stock cutter is that the steel hasn't been recycled so many times (tin cans, battleships, cars, etc.). Iron gets tired, like people.
In all the metallurgy and materials engineering lectures I sat in, they never talked about iron getting tired. You should probably write up your findings and get them published.
@@Rich-on6fe Metal fatigue??? :-)
@@tpobrienjr I hope that's intended as the joke that I know it to be :)
Hi Keith, sounds like you need some kind of Involute cutter library service... or in other words a place where someone could rent a cutter for a job.
_Nature abhors a vacuum_ so maybe someone need to make this a reality?
Cheers,
Nice... bummer that Keith doesn't make that cutter himself... 😉🙂
Shared expertise is appreciated....................
Never have the one I need; it's not just you Keith.
GREAT JOB, GREAT VIDEO, NOW LET'S GO TO WORK...
Are we going to see you machining the steam valve stems, that Clarke Easterling cast for you?
Just learned that Keith Fenner is now on Rumble....
Time to change to rumble!🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸
Short, or long, machining is machining. Great video.
Thanks for sharing.
You could just take the 28 tooth gear and grind off 6 of the teeth.
lol
Well damn... that sounds a heck of a lot easier than all the rigmarole Keith is going through! 😂
Might run a bit rough at first but...
it will smooth out with usage.
Hey, it's obvious, isn't it?
🤦♂️
There are lots of gear-cutting videos out there, but I've never seen a gear-uncutting video.
Are the gears made out of hardened steel?
Me either! What a clever re-use of redundant tooling!
They certainly looked to be given the colour of the chip coming off of it when turning the full diameter. I had expected the gears to be cast iron but given it was to drive an industrial attachment to a big mill I suppose K and T decided to go the steel gear route.
Keith, I'm covering what bases I can cover. I would be calling you, but don't have a number. I sent a priority email to you it has a link to an Ebay listing and in this listing you have the choice of #5 or 6. They are listed as US made. If by chance there are others you need you can probably find them through that same seller.
Dead-nuts on - using a set of approximators.
Hiya Keith
Hello sir please teach a radial drill slide scapring
As usual, Great video Sir. just wondering if those gears have hardened teeth. My VN 2L uses nothing but , what appear to be induction hardened gear teeth, ? Just curious. Thanks again for sharing another informative video .
Does Mcmaster Carr sell the cutters you need?
I'm wondering where the "play" from the interrupted cut occurred to make it slightly tapered (10:35)- dials moving around? . Also, does that explain the small serrated edge/ring (9:21) on the far side of the first one that was cut ?
Eager for Adam to get the steam stoker engine back to you. Would like to see progress on milling those surfaces flat.
Victor Machinery Exchange , #5 Involute cutter, $47.00, new. Interesting work.
I wondered why he was going to do that.... it has a spline.
👍👌
Are chamfers to break an edge calculated or just done by eye?
Nevermind, he answered later in the video haha
Does the cutter head like jump the first second when engaging the part?
Those cutting inserts are crazy tough to go nose-to-nose with a steel GEAR!! unh
@@mdouglaswray I don't understand what you're typing.
Are the teeth timed to the internal splines in some way?
3,193rd!🎉🎉⚙️⚒🚂
Your involute cutter issue is similar to my nut/bolt/screw issue. I probably have 100,000 nuts/bolts/screws in my collection...and I NEVER have the one I need.
So I would buy a box of 50, use 3, and then have an inventory of 100,047 fasteners that never fit anything again.
@@kensherwin4544 exactly....lol
I know your decision to cut down those gears is the right decision, but it just makes me cringe to see perfectly good gears getting cut down like that.
SkylersRants: I hate it too, but sometimes in this business you gotta do what you gotta do. Now if those gears were hardened and ground he'd have no choice but to buy new ones.
Yep, same :( If i was more confident with my shaper I'd offer to make him a bunch of blanks with the splines already cut so he didn't have to ruin those gears!
"cringe"....The most overused word in UA-cam comments!
Can you put your videos on Rumble as Well.
Why can't you duplicate the spline with a keyway broach? You can mill a keyway or drill a pin to allow you to do a 60 degree index on the bushing and use it after the first slot is cut.
Because he already had ten spare gears with the appropriate splines ready to go?
Keith, I have watched many of your videos, one thing you say when you are taking a measurement or telling us what size you are aiming for you almost invariable say "About" such and such size, and for a precision engineer the "About " seems rather incongruous lol I bet you don't ever realise you are saying it!
There are some very important reasons for sourcing tools and parts other than from China. Please do your best (and encourage your viewers) to follow your lead on this.
While I completely agree, it can be a matter of money. I recently got a set of chinese 16P cutters for about $80, and they work great (other then the fact that I had to make a 22mm arbor for them). Prior to that, I looked for a set (or the two sizes I needed), and ebay had nothing US made at all. Well, one of the cutters was available, but it was $140 used and rusty at the time.
@@componenx - Of course this isn't the place to go into it deeply, but there are some issues at stake that are a whole lot bigger than money. Peace.
@@donhalley5622 I understand, believe me; but I had to get the project finished on a very limited budget. I always look for American made tooling first!
Made a quick eBay search and sadly only saw anything remote from China, Sorry Keith
Don't need a form cutter if you have a surface grinder. Rough cut on the mill with slitting saw then finish with a form wheel?
Never should have ruined old GOLD when a $15 hobbed coupler is available. Section it into gear thickness blanks chamfer both corners for a welding vee then machine a donut to fit. Finish weld, sides and diameter on a lathe. Machine or grind the gear teeth as needed until the cast bracket arrives.
Nice! :-)
what the heck happen to the steam stroker engine project dont see that anymore
It is being returned to his shop. It turns out Adam's shaper couldn't quite reach enough to do the job. Keith has recently brought a horizontal mill into the shop and feels he can make it work. It will be an interesting project!
Measure once, measure again.
It’s not a sin.
Measure a third time,
For the win!
😊
What are those gears made from?
Unobtanium!
@@shadowdog500 Obviously not, since he actually has them.
Unobtanium is used to make all factory racing parts.
RIP gear :)
I understand but I hate to see destroying old tools to make new tools.
youtubers in general have a tendency to repeat themselves and state the obvious.
Yes, most of us aren't used to talking to an audience - especially an audience we can't see :) Trying to cater to both experienced machinists and noobs like me must be hard :)
@@AJBtheSuede agree
I am not a youtuber but I do that all the time.
@@royreynolds108 It's never bothered me, and I guess you get comments like "you didn't explain this/that!!!!!" all the time if you run a YT channel :)
I'm just happy to be able to learn something
Good teachers do that too. Tell 'em what you're gonna tell 'em; tell 'em; and tell 'em what you just told 'em.
It's not because the steel is better. It's because it was made here in America by American Craftsmen when we provided 99% of the things we needed on our own
Made in China,now more than ever that phrase makes me want to vomit!
Can’t wait for the WW3 and we are waiting for China to make the war supplies for us.
@@OCT566 You don't have to wait. It is going on right now. It is just a cyber/intelligence war at the present. Just ask the new guy Beijing Bribe-em'
I would've turned the teeth off in a single pass and leave only 80 thou for 2 equal finish passes. 3 passes total.
Don't you run the risk of breaking something if you are that harsh?
@@jimthesoundman8641 no but the tip is wearing out prematurely by taking too shallow cuts and the tip can also chip from the impacts.
@@MF175mp But, the video would have been too short and viewers would have missed that wonderful zinging sound of the teeth being removed.
@@MF175mp With the carbide available today cuts like in this video are not really a problem.
First :-)
Thanks for sharing!
