Shaper gear cutting

[@victoryfirst2878]

I have not seen an attachment for the shaper of this type in forty years. Nice job working on the gear.

Beautiful design and workmanship. Thanks for sharing. (I knew I should never have sold my shaper, lol)

Nice to see your old shaper working. Mine is older, doesn't even have a clutch, you have to turn the motor on/off. The ways on mine are in similar shape to yours. I plan to scrape someday, but for now it gets the job done. Enjoy your videos.

[@JBFromOZ]

It’s really awesome seeing different approaches to this problem! The solution I implemented was due to not having the gears of the pitch required, or a rack, or indexing head available. In practise we use the tensioned wire approach to drive our embroidery machine pantographs at high speed and they maintain 0.1mm positional accuracy day in, day out. The only other setup items required are a disc turned to PCD and a disk cut with index slots for the desired number of teeth. Worth a look in my channel if you are interested in that method, which also includes a build series in the playlist

Fantastic, I have some machines but the one I most admire is the planer, a simple machine and few are interested but it is very useful in small companies, greetings from Brazil 🇧🇷

[@ogaugeclockwork4407]

Great work! I learned in an old dirt floored blacksmith shop, your workshop makes me miss it!

[@paulgreenlee190]

You have one of the neatest shops I have ever seen. Everything is sitting on a packed dirt floor. Any issues with ants? I just a hobbyist machinist if that much, my career is welding/fabricating. I was a tube welder and a pipe welder among other things. You have to be a genius to keep up with you, your videos are great, and I will surely watch them several times to get all I can out of them. I only have a lathe to work with, wanted to find a milling machine but it's ridicules what some folks are asking for them. I thought about a shaper if you can find one in good shape that is. Seems to me that you could do a lot of machining with a shaper alone that is after you learn all the features and how to operate it. Anyway, thanks so much for sharing your skills and videos.

[@JohnDoe-ce2wl]

I would have loved a camera angle along the direction of the tool movement and looking at the slot between two teeth being formed. What would also have been great: showing the motion where the table is cranked back to the starting position in the beginning, as this makes tangible the way the axes are coupled and how the motion is orchestrated. Very nice setup!

[@mattblack156]

This method of gear generation is how a Sunderland gear planer works, using a rack form cutter to generate a gear tooth form on a round work piece. Nice work!

[@stephensarkany3577]

No I haven't watched the whole vid yet, but the greatest part of this setup is that the cutter is a rack form not involute, so it is perfect for generating any number of teeth. I want a shaper.

[@stephensarkany3577]

Except you can't index prime numbers with that indexer. With a modification like a lathe banjo and interchangable prime driven gears you could use it like a direct indexer.

[@logicalguy488]

Amazing, never seen a shop like that. No walls, sand floors and flip flops on the feet. I bet the machines take a beating and get covered in sand.

[@shaunbrennan5281]

Thongs mate... or maybe double pluggers not flip flops. Unless you're a seppo.

[@grahamsengineering.2532]

Great looking setup there.

[@craigtate5930]

Awesome setup! I even love the oiling wick you have on your cutter. I tend to put the oil right on top of the tool as well and let it run down. But this is a much better idea

[@Rustinox]

The only real way to cut gears on a shaper that I've seen on youtube so far ;-)

[@eyuptony]

Hi Neal. That's brilliant. So do you change the gears like on a lathe to obtain different pitches? I like the paper towel trick to hold the coolant. Love your airy workshop. Tony

[@nealblackburn8628]

i got a universal dividing head which comes with a selection of change gears and the idea was to make use of something i already had... actually you need more than you get with a dividing head but it is a good start and you can cheat a bit and use a gear which isn't quite right or you could use the tool to cut a gear by indexing for the number of teeth and do a plunge cut for every tooth....you change the gearing so that the gear you are cutting turns at the correct speed .....Geoffery Crocker does a good of explaining what is going on in his video

[@nealblackburn8628]

if you got change gears from a lathe you could build it to use them ..i built it to use the change gears that i got with my dividing head

[@sion023]

It's brilliant, elegant design, do I understand correctly that it is the pitch circle diameter that needs to rotate at exactly 1:1 with the table traverse? I also have a dirt floor workshop with no walls, mine has the disadvantage of being in Wales, so dirt sometime means mud. I have heard of something I think it's called 'concrete' which may improve things one day.

[@nealblackburn8628]

that is correct and if you have the right change gears that is the way you set it up but if you havn't you can cheat a little bit and make a gear with the right number of teeth (that can be done with the indexing bit of the device ) and a gear profile that is not quite right and then use that to cut your gear

[@sparkiekosten5902]

[@MrSmithDotShop]

I would think whatever change gears you choose it would need to be 1:1 between the rack and the cut gear. In the 48 tooth example I'm guessing you have a 48 tooth on the rack and two 60 tooth gears at the driving end. Or another way of thinking about it would be cut gear (48) + 60 tooth welded gear = # of teeth (108) required on the rack side. Am I missing something?

[@timogross8191]

How did you make the blue thing? I would like to see that. Especially the indexing part.

I’d love to see it also. Fascinating and brilliant !!

[@mariaramirezcastro5936]

Amazing... I'm highly into watching that tool

[@howardosborne8647]

If it is a 60 tooth gear being cut then i would think it needs to be a 60 tooth gear in mesh with the driving rack or a ratio train of gears that equate to the same.

[@nealblackburn8628]

thats right but you can cheat a bit if you don't have the correct racio because you are only cutting one tooth at a time so the error might be very small just the same way as gear cutters cover a number of different gears

[@MrSmithDotShop]

Neal, I have a Värnamo SH-2 14" shaper. I've been thinking of making a gear cutter for mine. I like the rack driven design, most I've seen use a cable tangent to the pitch diameter. The video cut off right when you were describing the gearing. It appears you have 48 tooth on the rack and a couple 60 tooth gears opposite. Is that correct?

[@nealblackburn8628]

tried to reply to your email didn't send... the 48 is being cut.. the 60 is permanently welded to index housing .. the others i might tell you later

_Hi Neal, I love to see "boot strap" engineering in which you generate an involute from a trapezoidal cutter!_ _How did you pre-slit the tooth spaces in your blank? Did you use the shaper with live advancement disengaged?_ _By the way, what was your module/DP and pressure angle on this job?_

[@nealblackburn8628]

you don' need to pre slit the tooth spaces, the indexing component makes sure the teeth are all properly spaced...i know the photography isn't the best and it is hard to see what is going on...i want to do another video to explain more but too busy at the moment ...its a 12 DP with 20 pressure angle

so it starts off cutting at a tangent and then the rotation brings the gear into the verticle pane of the cutter ?

Didn't get it, how You know when the gap cut is done and it's time to move to the next tooth. Rustinox recently showed his way of shaper cutting a tooth wheel. -didn't understand him either... Your foot ware is not very protective. Don't You chips and swarf in Your feet?

[@nealblackburn8628]

watch again and when it gets to 2.28 you will see me advance the indexing unite one tooth .... if you watch the Rustinox video you will notice he unscrews a little pointed bolt and moves it around one tooth on a gear he has attached to the shaft ...it is plain to see if you watch our videos completely ...but i don't know what your video quality is like

[@Stefan_Boerjesson]

@@nealblackburn8628 I saw that but how do You know You've reached the point to stop cutting and advance the index?

[@nealblackburn8628]

what happens is the cutting tool goes into the gear ( to be cut ) and then comes out ...when it comes out it is time to index to the next position.... But the tool doesn't actually move to achieve that ..the gear blank itself moves across and rotates under the tool to achieve that ...don't be lazy watch carefully and you will work it out@@Stefan_Boerjesson
