Hi Keith, I sure appreciate all of the time & effort that you put into your videos. I'm an amateur & don't know anyone in the business that I can learn from. This is absolutely awesome, just like being there. I spent 12 years surveying for the American Bureau of Shipping & wish that more of the shops I worked with were like your. You're squared away, a straight shooter & you're willing to share your decades of experience. Thanks again for your videos. Best Regards, Jon
Keith- The ladies ask me why my right arm is so strong; I tell them it is because my hydraulic press is manual. :-) I have never watched it being done (broaching)-Kind of knew but now, watch one, do one, teach one and another great vid. I really believe there is nothing you cannot learn, and it really helps to have a good mentor who explains things practically-most books go on and on about stuff you don't need to know. Not you! Straight and to the point to do the job-Thanks! -Christian
Thanks guys, for the comments, the camera picks up the noise a little more than it actually is, but understand if garage is connected to house, even sometimes I drop heavy piece and wife runs out to see if I'm alive! LOL. I did not have press before I made this one. Let me tell you life is to short to just talk about it! almost everything in press is used stuff! ;{)---
What I really appreciated about this piece is that it made me see that a keyway guide can be devised to apply a lot of different ways - not just the "kit" way, as long as your arbor press, hydraulic press, or I suppose mallet or sledge can gain access. Out of the box. Nice.
Saw CNC broaching like 1000 times, never knew how it was made "ye olde way". Interesting stuff. I also like your DIY shims: creative recycling - cheap & smart. Respect and greetings from Germany.
This is great! Thanks, I'm taking a class on manufacturing processes, and they really don't get around to showing us what really happens in machine shops. Your videos give great insight! Thanks!
i bet i did a thousand of these in my day and as far as the lip action goes it seams every machinist i ever worked with had that - i did almost all mine with a dake arbor press by hand i sure wish i had this set up great job-had a brotch shatter with me 1 time in 13 years man it was like a bullet lol
Nice video. I've also used the steel strapping as shims. Usually when I'm milling a flat on an OD. Stick the work on some parallel surface in the vise, add a couple shims, mill the flat, add a couple more shims and mill the same flat on the opposite side. Works consistently. I was a little worried the drift would pop out at you.
Great videos sir. Though I'm a CNC Latheman by trade, these bring me back to my grandfather's garage shop getting covered in oily cold rolled chips. Keep up the good work!
" lip action optional" hahaha, We all have quirks. I make some sort of face when drilling a hole or the like around here at home and my wife always get's a kick out of asking me why i make that face... lol,,we laugh and go on with our project. Thanks for sharing the work you do.
Wow,I subscribed to your channel a little while back. You are a master at machine work ! I set and watch in amazement at some of the things that you have taken the time to video . Keep up the good work Keith,I know you will . Thanks,Rich
Propellers have taper bores and the guide is tapered to match those bores, the grove that supports the broach in the guide runs inline with the taper, so the key-way depth stays the same depth...
Cool Keith I was going to ask about the lube too on the bronze. Sometimes you can smell the sulfur when you machine cast iron especially parts right from the foundry. That's a great idea for the shims, that steel usually pretty hard. Also razor sharp when cut with snips....don't ask how I know.
I've not seen this done before. Thanks! And a hint of funny irony, its Oct 17, 2013 and they are saying maybe an early snow... the music in the background seemed fitting. Lol. Thanks for the tips!
I was always taught to measure from the center of the key across to the other side of the bore with a caliper and cut for dia + 1/2 the width of the key.
I have never seen or even thought of using a press as a cutting tool. Is this common practice in the shop? It's amazing to me to see how things are done. I always have dropped parts off and picked them up done not thinking of how they did it. Sometimes I get on a Turn Write binge and watch videos for hours. My wife says "Thanks alot Keith"
I have done keyways in propellers on the shaper with such jig mountings,before, It does take a lot of time, but some keyways are special and there is no standard broach for them. ;{)---
Hey, thanks for the comment (rescue) Keith on the time consumption factor. The other guy suggesting that a shaper would be a faster option (lol considering that you have a big broach kit, and a number of premade broach guides) is just one of the long list of knowitalls on the internet I guess. And lol again - I can hardly make out what we're talking about when translating our languages to english with google translate.
The broach guide slot is milled inline with the taper so the key way depth remains the same depth for the length of the taper, by shimming the whole project the guide and push ram are aligned. ;{)-----
All or most of my broaches are over 20 years of age and still cut nice. In English or dollars; Broach job = $50 minimum so 50 to 100 broach jobs in 20 years = $2500 to $5000 minimum per broach life. Remember the better you take care of your tools the more return you get out of them! ;{)---
Ciao Keith,guardo sempre i tuoi video,imparando sempre piu' trucchi del mestiere.Mi piacerebbe tanto lavorare al tuo fianco,sei tanto bravo..............Un saluto da Giuliano
Hey Keith, that is one awesome process! Dude, I was intrigued! But, I bet that process becomes really old and tedious after the first time. Ha ha ha ah .
@vondeliusc Christian, I'm busting a gut, glad it was a new topic for ya, thanks for the Kudo's... I figure if I, walk the talk, theres way more info than a lecture and hits on some things I may not of thought to pin point on... Keith
Well, most of the time you judge the lathe your going to buy by the size of your projects and the cash in your pocket. Your room to use it is also a good factor and the type of electrical you can supply it. ;{)------
Is the keyway always aligned with the centre of the blade for strength in a prop. You can grind a recess in the end of the broach so your push rod can't slip.
In watching this broaching video I realized you need to go find yourself one more toy, a little Davis keyseater. Not one of those single tooth jobs, but a real Davis. I have had a good old one in my shop for a few years now and could not live without it! Lots easier, and faster!
Banding is very useful. I use it to hang items, or just to make a quick knife. I have also used banding to make springs. Also, other shit...like scrapers...
I thought the same thing. I saw a guy launch a 1/2" peice bar stock at somewhere near the sound barrier out of a press once. Scary to think about taking it to the face.
I watched a bunch of videos on broaching and I think I know know the best way to cut internal or external key ways. I think a lathe carbide broaching tool attached to and incremental slide plate (motorized) which is then attached to a trip hammer clutch. Broaching made easy and faster than CNC thanks to faster oscillations due to the trip hammer clutch.
i was thinking the same thing, i work for a company that does this and we cut our own shims with sheet metal from .002 - .020 then whatever other shims we need we go and get but i hate having to recut shims after every pull.
Jaysus! He's a real machinist but that pusher gets cocked just a little bit he's gonna catch it in his pie hole! I worked in a machine shop for 25 years. This'll work but a real broach machine is a helluva lot safer.
I know this video is old but I think for larger diameter holes it would be possible to create a right angle end mill that could fit in the hole and carve out the broach.
Keith, I'm sure you know what you are doing, but you mentioned cutting a tapered slot, hence the key stock under your backing plate. But it seems to me that if the broach follows the guide, then either the guide slot or the guide itself must be tapered; i.e. unless the broach moves at an angle to the axis of the shaft, the slot will not be tapered. Angling the workpiece will only change the angle at which the press imparts motion to the broach. Did I miss something?
I noticed you aren't using cutting fluid. Is that just because you're cutting bronze, or do you typically not use cutting fluid when broaching? Excellent videos, Keith, I couldn't subscribe fast enough.
You said that the slot (keyway?) wasn't a straight one, but was at an angle. As it appeared that you just "willy-nilly" created SOME-SORT-OF angle, by placing a 3/8" piece beneath the thick ring of steel, I'm assuming that the degree of the angle wasn't critical. Is that correct?
hello good night, I had the pleasure of seeing your video, parabens very instructive, would like to know the name of this equipment, surely here in Brazil will not find from already thank you for your attention
I thought i was the only one to make a home made honing tool from taped together sand paper!..or is that one of them there fancy ones? I always bite my tong...Instead of lip action..LOL
Also, never use a hardened piece of material to push your broach through. If it get's stuck and start's to bend, it will shoot across the shop like a bullet !! I had to learn that one the hard way.
Oneday that push pin used to finish off the broach pass is gonna fly out at 100,000mph Oneday, and youll be hanging down face level cause you catch the broach by hand when it finishes its feed through. And thats going to suck! Hopefully it never happens!
I've got a question I don't have a brooch ink it and I'm going to buy a small one I think it's a couple hundred dollars so it's not a real good one or a real extensive on. Do they noticed okay it gives you these bushings there random sizes from small to you know maybe inch and a half to use in broaching random diameters but they seem almost useless. I mean what are the odds that I get a size bore that these bushings are going to fit properly? Are you supposed to make your own? I'm fine with that I just don't understand why they would even include the slotted bushings in a kit I mean seriously? I'm going to be doing many different size gears and pulleys I can see maybe having a 5/8 or 7/8 or 3/4 handy but other than that there may be a lot of custom stuff. Anyway if anybody could clear this mystery up before I buy my kid would help me a great deal

I really appreciate you taking time to post your vids. There was no such info years ago until youtube.

I really liked the effect of the little bubbles floating in from the left hand side. It sort of lightened up the subject of broaching.
This is great! Thanks, I'm taking a class on manufacturing processes, and they really don't get around to showing us what really happens in machine shops. Your videos give great insight! Thanks!
Great video Keith, especially the close up shots. The lip action was totally necessary! 😀

We miss you Keith.
Hope you are well in your new facility!
Wow, thanks for the quick reply. I watched the other videos and learned some new things--really appreciate it!
Aaaahhh! So that's what a broach does - often wondered how to use one. Cheers!
Yes the keyway is always aligned with one of the blades.
Nicely done. The power press helps, Mine is manual.
I wondered how they make those cuts... thanks for the video!!
I've not seen this done before. Thanks! And a hint of funny irony, its Oct 17, 2013 and they are saying maybe an early snow... the music in the background seemed fitting. Lol. Thanks for the tips!

Watch my two videos on Press Talk 1 & 2, and read the comments. ;{)---
Ive just broached 60 3/8 x 4" slots on a manual broaching press, when my arm works again Ive got to make a press like yours!
Most impressive, brilliant!
Thanks for the comment! I hope to visit Hong Kong, maybe next year My best friend lives there. ;{)-----

Thanks for sharing always wonder how they make a tapered keyway.

Outstanding Keith

Banding is very useful. I use it to hang items, or just to make a quick knife. I have also used banding to make springs. Also, other shit...like scrapers...
We increased the bore size to the next shaft diameter, causing the need for the next size key, with new width and depth requirements. ;{)---
I thought the same thing. I saw a guy launch a 1/2" peice bar stock at somewhere near the sound barrier out of a press once. Scary to think about taking it to the face.

Broaching made easy and faster than CNC thanks to faster oscillations due to the trip hammer clutch.
I always say you got to hold your toung right to put some parts on, a must for sure LOL!!
I like to use a couple of drops of oil/lube on the back side of the broach as sometimes the shim can get sucked in with the broach.
i was thinking the same thing, i work for a company that does this and we cut our own shims with sheet metal from .002 - .020 then whatever other shims we need we go and get but i hate having to recut shims after every pull.
Jaysus! He's a real machinist but that pusher gets cocked just a little bit he's gonna catch it in his pie hole! I worked in a machine shop for 25 years. This'll work but a real broach machine is a helluva lot safer.
On soft bronze I prefer not to have the mess, sometimes if I do it is more for the shim side to ease the drag. ;{)-----
Did you make or buy your press? Can you do a video on your press? Great work,i really enjoy your vids. Iv learned alot.
I know this video is old but I think for larger diameter holes it would be possible to create a right angle end mill that could fit in the hole and carve out the broach.
Mats Moreau there are milling attachments, but big diamater holes are almost always done in shops with specialized machines
Thanks for the great video. What kind of press is that?
Keith, I'm sure you know what you are doing, but you mentioned cutting a tapered slot, hence the key stock under your backing plate. But it seems to me that if the broach follows the guide, then either the guide slot or the guide itself must be tapered; i.e. unless the broach moves at an angle to the axis of the shaft, the slot will not be tapered. Angling the workpiece will only change the angle at which the press imparts motion to the broach. Did I miss something?
The guide slot is parallel to the bore taper.
It is a straight push key way broach, found in MSC catalogs ;{)-----
Hi keith I am just on board also. ;) What is the machine you use to press the broach down it seems like its electric powered??
Thank you for sharing.
I noticed you aren't using cutting fluid. Is that just because you're cutting bronze, or do you typically not use cutting fluid when broaching?
Excellent videos, Keith, I couldn't subscribe fast enough.
The pressure surge due to the cut variations as the broach is forced through, contacting each tooth one at a time! ;{)---
wow! that's some force!!! how many tons is that press ??
What causes the vibration on the press table? It looks almost like an impact wrench motion.
@billdlv The tuff size to find on the banding material is for the 3/8" and under broaches...
Yes some times a prop is also referred to as a wheel, you hear that phrase more in prop shops and marinas. ;{)-----
Hydraulic press a lot better to broach with. Last time I broached a 1/2" keyway, could barely move my right arm for a couple of days.
Buongiorno Keith,ti scrivo da Roma,Italia.............Un saluto
Why add more depth to an already made keyway? Did it strip out?
The throw away strapping that you usually throw away
Good work.
None on a plain bronze wheel, sometimes I do on Nibral wheels and most other alloys except cast iron...
no lube or oil at all? dont you need it for broaching, or is it because the prop is made out of brass?
You said that the slot (keyway?) wasn't a straight one, but was at an angle.
As it appeared that you just "willy-nilly" created SOME-SORT-OF angle, by placing a 3/8" piece beneath the thick ring of steel, I'm assuming that the degree of the angle wasn't critical. Is that correct?
No lubricant?
Not needed. Low speed
hello good night, I had the pleasure of seeing your video, parabens very instructive, would like to know the name of this equipment, surely here in Brazil will not find from already thank you for your attention
Just curious, a prop is called a "wheel"?
If the broach guide is tapered, how does it give you a consistent slot depth?
Wouldn't it allow the tool to move around?
michael atkinson only the very last tooth will set the final dimension the whole way through
I thought i was the only one to make a home made honing tool from taped together sand paper!..or is that one of them there fancy ones?
I always bite my tong...Instead of lip action..LOL
I found an improvement after using the lip action.
Chow down some brass and aluminum.
No cutting oil required ?. Because it's brass ?.
Also, never use a hardened piece of material to push your broach through. If it get's stuck and start's to bend, it will shoot across the shop like a bullet !! I had to learn that one the hard way.
Lip action is required if you want a job done right!
Great tool
That was cool
Keith I can't remember those blue digital calipers you like can you let me know the name.

Keith Fenner thanks
Quality lip action!
Yes, old school techniques, still used today. ;{)-----
loveit.
Hmmm will I get the same effect if I vary my lip action I prefer the tongue in check method I seem to get a better result
I hardly dare to ask the price of a broach like that?
You can look them up on mscdirect.com, they are steep. ;{)-----

Ever think of making a pocket for your pusher in top of broach
I've got a question I don't have a brooch ink it and I'm going to buy a small one I think it's a couple hundred dollars so it's not a real good one or a real extensive on.
