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.

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

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

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!

Check out my two videos called press talk 1 & 2...Cheers...

Very nice video Keith. You did a nice job of explaining why you set up and finished as you did. I completely agree with you about strapping, it is made out of surprisingly good spring steel. (Engineer of 35 years practice)

"Lip action optional." Bwhahahaha! You caught me off guard and I almost laughed my beer out my nose. Thanks for the laugh.

Great video Keith, especially the close up shots. The lip action was totally necessary! 😀

thank you your youtube clips are great bits for information keep them coming, great way to learn about how to do things in my own home work shop.

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.

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!

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

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

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

Keith, Hiram up in Vinalhaven Maine. would just like to thank you for your knowledge of machining and all of the above. You do superb work, and are truely a craftsman. Keep it up.

Thanks Keith, Always enjoy your videos. Even an old dog like me can learn something! Rob

Thanks for the comment! yes even when I bend a 90 on the top side they get pulled in sometimes. A light coat of oil helps sometimes too. I like your idea. ;{)-----

I learned something. Thanks! Keep it up Keith. Greetings from Germany.

Great video.. great idea for the strapping material, and it's come in very handy, Thank you.. I found that as I put more strapping "shims" on, the shims did a little traveling due to the down pressure.. my solution was to weld a perpendicular pin to a small plate, and punched a hole into every shim, so when you dropped it onto the pin, it stopped the downward motion of the shim in contact.

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.

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.

Wow, thanks for the quick reply. I watched the other videos and learned some new things--really appreciate it!

@billdlv The tuff size to find on the banding material is for the 3/8" and under broaches...

Thank you for all of the movie, I was in Hong Kong, work is cnc lathe and cnc milling,. Your movie made ​​me learn a lot of ways to go down immediately useful

Most impressive, brilliant!

Beautiful key slot. Modern technology can't replace this method .

" 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.

Outstanding Keith

I wondered how they make those cuts... thanks for the video!!

That is excactly how i set up props for broaching, too. And it´s excactly how i set up props for boring in the manual lathe, too... looks like you´re just as clever as i am ;-) Props to you, from a professional prop-smith from Denmark...

That's because it's generally standard practice with conventional machinery -- they've been doing it that way for more than 100 years. Nothing new or clever/different.

Aaaahhh! So that's what a broach does - often wondered how to use one. Cheers!

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.

@Jim911Bo Some times I do on Nibral, but most of the cutting was free from the remainder of the 7/16" keyway, if at all, i would use some lube on the shim side to ease the glide... No lube on cast iron, broaching, turning or milling!

Thanks for the Comment and welcome aboard!

Nice! Thanks for sharing.

@oneyaker Thanks for the major Kudo's there, I built my jobbing capablities in stages... There will be more to come, as the work keeps rolling in, Keith

Thanks for the comment! best wishes to you in France, right? my guess anyhow... ;{)-----

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...

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

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 .

We miss you Keith. Hope you are well in your new facility!

Watch my two videos on Press Talk 1 & 2, and read the comments. ;{)---

We increased the bore size to the next shaft diameter, causing the need for the next size key, with new width and depth requirements. ;{)---

Excellent video. The lip action shows concentration and focus and is therefore pretty much mandatory.

Thanks for the comment! I hope to visit Hong Kong, maybe next year My best friend lives there. ;{)-----

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!

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.

Informative video, thank you for sharing

Yes the keyway is always aligned with one of the blades.

I was woundring how this grove get machined. thank you for the vedio. it is very simple yet effecient method.

BWAHAHAH!!!! Lip action optional! XD Keep up the awesome work and vids, Keith!

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

I to am learning better and faster ways on working on oil field engines and pumping units, Thanks from Ohio Keith....

Nicely done. The power press helps, Mine is manual.

Dang, you made me jealous. I used to have to do tricks like that with an arbor press and a giant cheater bar. LOL

Cool trick with the strap-shims. Reduce Recycle Reuse!

simple and instructive! thanks a lot!

Thanks for watching over there in Italy, best wishes to you and your family! ;{)-----

Good job man:D

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. ;{)---

Amazing! The first time I saw!

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! ;{)---

@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

Thanks for the great video. What kind of press is that?

Thank you for sharing.

That was great, thanks mate.

Good work.

Ya, your right! I have run some nice broaching machines but for a one man shop with only an occasional need to broach, this makes more sense on the cash flow! LOL thanks for the comment ;{)-----

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"

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...

That was cool

Sure be glad to have you swing by!

Looks good .

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.

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!

I would very much like to see how these broaches are made.. There are incredible forces on thoese broaches..do they never snapp..

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. ;{)-----

Good job!

I always say you got to hold your toung right to put some parts on, a must for sure LOL!!

Of course I learned a ton..Thanks, I am looking for my 1st shop lathe. How big of a lathe would be the first lathe?? 36" 40" ????

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.

Hey Keith, can you provide any tips on broaching stainless steel?

Thanks you for the comment! ;{)-----

Great tool

None on a plain bronze wheel, sometimes I do on Nibral wheels and most other alloys except cast iron...

btw merry xmas to and to your family! lol. good bkground music

Quality lip action!

good stuff thanks for the vid

Yes some times a prop is also referred to as a wheel, you hear that phrase more in prop shops and marinas. ;{)-----

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!

Buongiorno Keith,ti scrivo da Roma,Italia.............Un saluto

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.

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.

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.

lip action, priceless

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. ;{)------

Love the lip action "hahahaha"

It is a straight push key way broach, found in MSC catalogs ;{)-----
