K&T Mill Horizontal Slitting Saw Action
Вставка
- Опубліковано 6 лис 2015
- We set up a large sprocket which needs to be split in half. I utilize the horizontal milling capabilities on the Kearney & Trecker 307 S-12 milling machine.

My Dad worked at K&T in Milwaukee for over 25 years. Love seeing those machines still working.
first time I saw two over arm supports on the same arbor. Great show!
I like the way Stella comes in and looks at you as if saying "Who you talking to, nobody's there ?"
That may have been the truest-rotating mill-on-an-arbor that I have ever seen. Most of the time it is crunch-crunch-crunch, with a few of the teeth taking all the cut. Great video!
+Peter W. Meek should have seen the shaft last week, it was about to cut banana shapes, lol
I _did_ see it, and saw the fix. Even on straight arbors, the usual milling cutter runs like a Hula Hoop.
+Peter W. Meek It's Adam and his 'Dr Doolittle' taking to the machines :}
So glad you got the K& T up and running. Some really cool stuff can be done on those.
I learn so much watching your channel. I'm still setting up shop here with new (to me) Clausing Colchester 13x40 and Bridgeport. Have all my three phase from rotary phase converter still to run but honestly thanks, quite inspirational.
Jeff
Glad to see the mill at work and that it's working well. Good job, thanks for the video.
Always a pleasure Adam,
That's a good tip about doing a shallow precut to help tracking. I've had very limited slitting saw experience so I'll remember that for the future.
I always learn something from your videos, like the welded supports for lathe work! Sure beats the time I wasted customizing a faceplate to mount a pulley.
Adam, This saw slitting series and the machinist vise series were fun to watch. All machinists who watch you certainly learn a lot and have to admire your workmanship. Than you for all the time and patience it must take to make these videos for us to see. All the best, Joe
Thanks Joe!
From the show where you drove to Kilroy's to pick it up and all the patience to get to this point, it's been a trip watching the whole thing. Thanks for letting us in on the action.
It has been a fun adventure! Thanks!
Good action stuff and I'm excited to see her working.
Looks like the K & T is well worth your repairs! Nice addition to your shop.
am I the only one that is reminded of Clamps from Futurama every time I see the KT with the arbor supports?
LOL! Is that the lobster looking guy?
Abom torque I like it. Nice clean setup and a really nice saw cut.
The K&T is proving it's versatility for sure what a nice machine. You should certainly be proud of the good re-build you did on the K&T it's paying off.
Adam, thanks for the video I really enjoyed it.
Best,
Jeff
Nice series Adam,
Thanks
The puppy wants a treat.
Neat cutter bro.
I enjoy your videos, Thx!
this channel is gold ! thanks for making
Nicely done, One of them jobs that needs to be done on a horizontil
the Felix Unger of machinists another great vid
Man !! mill is looking good Adam !!!
I really like that storage thing in the Background when you were filing.
Lol I am always confused about the people that unlike your vids Adam. Great work, I have learned a ton from them.
Great video Adam really enjoyed it
Worked great, Good show!
The Elbo clicks when correct torque is achieved
Adam,
I like your "power hacksaw" you used to cut that sprocket in half! ... Regarding your weather, I'm getting "rain envy". Everyone in the country is getting drenched . . . except California! Oh well. When things get turned around, we will get flooded off the map and folks in Nevada will have ocean-side property. lol ... Thanks for taking us through your sprocket saga. It was interesting and great to finally see some horizontal K & T action! (Actually, I like most horizontal action! LOL)
Have a good one!
Dave
cool video Adam, as always. Man I love that K&T mill... Pretty versatile machine with good tooling...
Thanks Martin. I'm loving that mill also.
That cutter run-out is ..... something
Thanks Adam!
Like a hot knife through butter! I was wondering how that hole got cut in the sprocket glad you put those photos in at the end.
i like to watch u every week .great
Wow. That worked well, beautiful finish. There are times when a horizontal mill is just the ticket. And you have hit over 52K subscribers! Congratulations. Make some more videos and you will be abom60K.
great video Adam greetings from England
That was a great still shot through the cutting action, with the shop and flag on the back wall.
Good to see Stella. I think she's "Dad's" little girl! lol Cheers.
Oh yea!
great video , nice work ..
Stella just wanted to come in to approve the job! I have never done any sawing on the mill, perhaps someday I will get to give that a go as well. Enjoyed the action!
Comes in handy Bryan! Stella enjoyed her shop time with me that day.
Front row view! Nice
Another great Sunday morning, I'm glad I "saw" it!!...LOL Thanks!
Looks like a quick change race sprocket for a giant go-kart..Dave
Did great on its first job for you. I can't trust my eye balls. I would have probably needed to use a machinist square to try to line up the sprocket. Actually, I have been amazed just how close I've been able to line up punch marks for drilling using a wiggler point. They guys at the Ford garage that I worked at wouldn't let me line up the running boards we were installing. Have a good rest of your weekend.
There goes Stella!
Ey, Adam! Great work, very clean and... all use the torque wrench. Excelent, man!Another day at work, just that.
the K&T making money!
I think you like that K&T.
Красавчик без базара .
good video on horizontal milling. i have a van norman combination mill and i have always used the horizontal mode as a last resort, just lazy i guess. your video gives me some incentive to use the horizontal capability's more often. i really liked the set up you used to bore the sprocket hole, i'ii file that away for future reference . thanks adam
Nice horizontal action thar Adam. I aint seen any horizontal action in a long long time.
Brad
Been a while since I've done any myself.
Yep, life is still good though. Some machining moments are almost as good! Maybe better.
Brad
This is hilarious but i can relate.
The rapid feed at the beginning scared me. I had visions of being James Bond on the laser table in Goldfinger. :)
Must have been a torture scene, I don't recall watching that one.
+Abom79 It's the setting for the best ever James Bond film dialog. Bond: "Do you expect me to talk?" Goldfinger: "No, Mr. Bond. I expect you to die."
Nice work Adam. When you were setting up at the beginning, I was wondering why you just didn't use pins in the teeth and the center it that way. ( yes, I do a lot of milling at work ). The sprocket turned out great. To the folks commenting on the cut width when it's bolted back together, if it turns out to be a problem, a spacer the same width as the cutter can be made. I like that K&T more and more every time you use it. Jeff
i love it
Pretty slick slitting sir! Very enjoyable series, and excellent SNS too, thank you for sharing all of that with us. Must be cool knowing you've got Kilroy to holler at for any questions about that S-12. Not that you haven't got all of the experience you need to do great work, but it's got to be better than getting it on Craigslist, like my lathes?
It was a trip to hear the rain on your roof @ 19:32 echoing the rain hitting mine as I watched it this afternoon! I had to turn the volume up and down to see if I was hearing things ;)
Aloha...Chuck
adam some K&T action for the abom gang cool . bob
Love this and all of your other videos. My question is: Why is this sprocket being cut and why does it have to be so precise?
Abom torque procedure: turn bolt until 1/4 turn before breaking.
I was once asked how I knew I had 39 ft-lbs on a bolt. I said "39 ft-lbs is about that much."
I know what you need for the K&T.
It will double performance. Guaranteed.
Are you ready for this?
Racing stripes.
😊
Thanks for the video,
John
Back when I was a sprog it was 'farmer tight'. I think it's ABom tight from now on!
Nice.
KOOL video
Are the six (in pattern) holes lined up with brass bushings or am i missing something?
Have u ever attached the vacuum to the table? I used to attach my vacuum to my welding table with a spring clamp when I would rotor bur aluminum. Kept the mess manageable.
Cute optical illusion…looks like the K&T is moving across the floor when you rapid the table, rather than the table itself. :oD
The sprocket teeth line up with a t slot almost perfectly...
Hahahahaha "Hold onto your butts" I love it!
you'll work on any project. sign of a man going places. one question, why did you not use another set of clamps on the inside with such a big piece?
Is that a case hardened gear? The saw is HSS? Nice video. Good to see the K&T working now in the last couple of projects. Doug
Nice job on set-up and follow through. Next time you use the KT would you go over the controls, like setting speed, cut speed, etc. Thanks
I'll keep that in mind for a future installment. I do go over the over arm supports in more detail in this weeks SNS.
Heck yeah!!! :-D
AvE sent me here.
Welcome!!
When you did the first cut you were climbing. Puts pressure on lead. No vib.
Just a thought. Your vids are excellent
what's the sprocket being installed on? understand that the pre-drilled bolt pattern will hold sprocket in place and keep the space open from metal removed from splitting saw, but wondering if the two slots in the valleys will become a ware spot over time from the chain passing over them? would be nice to be able to see it after it had been in operation for awhile! great video Adam!!
Hey Adam, always enjoy you videos. What happens when the drive chain passes by the 2 teeth where the saw cut is? Or are the 2 halves indexed by the mounting holes? I must have missed that part. Thanks for another cool video
Puppy!
I don't see how the first pre cut does anything to help with the in-feed in the direction it was cutting from the bottom side of the sprocket at full depth, now if it was climb milling I could see it helping. Great videos though Adam! I have picked up a lot of good tips from you 😉
Just interested in how you would have approached the job if it was an odd number of teeth on the sprocket. It seems to me not a great idea to cut one tooth in half. Do you just move the cut line over a bit until it hits the next gullet? Or what?
Hi Adam, outstanding work!! I just seen your Dog walk past what's his story?
+Abom79 Nice one Adam, those Niagara's were a deal were they not? I took advantage of some of the sizes below 2", I am set for 2" roughers. Great work on cutting that part in half. Horizontal cutters are great a certain jobs, and this was one of them. I didn't catch what rpm you were running at, but looked like around 60, so with a typical 4" tooth count of 24 you were right in the ballpark for a .0015 to .002 chip per tooth with 2 to 3 ipm, at around 65 sfm. That's a really nice, conservative, setup for that type of cutter, they tend to be fragile and blow up if you push them too hard.
+James Kilroy I agree I try to stay around .002 per tooth on the not super substantial cutters as well. I think it is a good starting point for sure. Cutter explosions sound bad, I haven't done any of those but have certainly lunched plenty of end mills! :-0
+bcbloc02 If one of those thin saws tries to climb out of a cut and jams up, it will shatter in a spectacular fashion, parts can fly quite far!
Thanks James. Seems I still got it. I've done quite a but of sawing back in our old shop, and I set the speeds and feeds by memory, sight, and sound. I let the machine speak to me. But you were right about he rpm. 😎 Maybe one day we can do some deep cut slitting.
I remember both me and dad breaking some saws in the past. Sucks when you gotta buy another one just to finish the job.
Abom79
I imagine it sucks even worse when you get a big nasty gouge in your near finished part from cutter shrapnel. I know I hate that!
Why did the gear need to be cut and how are they going to replace the kerf width if they are reusing it? Nice seeing Stella again. Doug
What is the material? Looks like it cut like butter. When I used to have vibration set in we had some shot bags we would place on the part. Took up vibration real good. Also how does it locate on the mating part. The tooth pitch will need to be the same as if it weren't cut. You now have a gap. Another quality job by Booth Machine!

Adam just a suggest, but I would have put clamps on the inside as well, if you think about it, once you cut threw the right side completely, the only thing holding it was the outside clamps on to left outside, it could has pulled up when you came across to cut the left side... "Im no expert" just saying... Also, It was unlikely it would "spring and bind because of the size of your saw, but always need to be prepared for that as well... Nice Brian F.
Hey adam.. Why did you choose to have the blade cutting anticlockwise with teeth taking chips on top of the work not with cutter going oposite direction with teeth cutting down?
I really am new in this. I have started to have an interest in metal working since a year ago. I have yet to buy something ( some machine ) which i can build different things with. I am looking forw. to that :)But one of the first things that I learned was that for Cutting different metal one has to know how quick the machine must turn!!! and this is really slow?dont know if this is a stupet question or not. But that would mean that I can make a holl with my drail !!!? because I have tried and didnt work. what can I do ? ( Drail is making holl machine :) )
Are you cutting this sprocket in half to get it over a shaft that has too much stuff to take off and then they weld it back together? Only half way thru the video, just curious.
Is that normal Adam to cut on the "up-stroke" with the saw trying to lift the metal off the bed at the cutting edge? Any other situation I have seen or been involved with when cutting or sawing always saw on the "down-stroke" i.e. towards the groove in the platform.
It's normal to push into the cut, it's how I was taught. I don't like climb milling unless it's nesessary. On real thin parts it works fine, or when making light cuts. For heavy milling you have to have a backlash eliminator, which the K&T does. 😎
+Dan Whiteford Normal if you do not want to leave a trail of teeth embedded in the job by climb milling! Without backlash eliminator you do not climb mill.
Will this fit in my honda?
I don't know if an of the the other subscribers listen to jazz. I hope there are some besides me. The parallel to jazz is that so much prep goes into a performance that by the time of the show, you just take it on home. The hard work has already been done. I went to a jazz show last night and it was perfect in all regards. The pros had some university students sit in for a few songs. They did great. Not a one of them would have any competence whatever with machining. But they have put thousands of hours into honing their skills into something approaching precision.
Wut?
fuuuuuuuuckin bbitch?

My question is: Why should i cut this in half?
nice video man!
greeting from germany :)
+FabiAtDrums It probably needs to be installed in a place where they can't slide it over the OD of the shaft.
+FabiAtDrums i'm not sure about this sprockets application but split sprockets are common in chain drive systems due to the chain and the sprocket being high wear area's that require routine service and maintenance being able to easily replace these components reduces down time of the machine due to maintenance and repair work. the split sprocket is bolted onto a non removable solid disk on the shaft being driven by the chain.
the job seemed to pass Stella's inspection...
I don’t see how the precut helps as a guide, because the teeth of cutting disk enters to material from the opposite side during the final cut. Great video as always, thanks a lot.

How many guys closed one eye and lined it up too?
+Jeff Pinter I was trying to look at the tips of the teeth relative to the slot in the table ...
I did! 😆

When using the rapid feed on the Z axis of your mill, I notice you lift the rapid lever upwards. On your mill does the rapid lever also go downwards? I run a K&T S-15 mill where I work, and the Z axis rapid feed also feels weak when lifting the rapid lever upwards, but is fine when pushing down on the lever. Is it possible to try this on your machine? +Abom79
Hi Adam, Was that sprocket made in your other shop ?? Joe Morris
Adam Bomb, I dabble in this work, I hav a mill, lathe ,saw. I tune and weld repair train horns. I see you have a horn on the back wall to the right of the flag. What is it? Is it a chrome triple Pacific horn? Or possibly a Kahlenberg T3? Thanks for the videos!😬
I'll have to look at see. Can't remember now. But they do sound good! I hit them once in a past SNS.
Why split the gear?
Is it me or is that axis wobbling just a bit?
no fun zone sir abom.
You were using the German torque specification for the job, which is "gutentight".
That's it!!
Torque wrench? I was trained that one grunt = 25 ft/lbs.
Why are you cutting upwards and not downwards with the saw?
Because on conventional mills you want to conventional mill, or "push" into the cut verses pull into it. There are times where climb milling works to your advantage though, especially on thin work parts.
