This is how to broach a key slot (keyway) in a pulley. I am cutting a 3/16" wide slot in a 5/8" bore aluminum pulley. This DAKE #0 ARBOR PRESS is a 1 1/2 Ton capacity.
Thank you for all of your very informative machine shop videos. I’ll be forever grateful. I’m glad I found your UA-cam channel.
Sincerely,

👍👍👍
Necessity is the Mother of Invention!!!
This is the kind of thing "You Tube" is great for....Learning from those who know how to do things.
I dont waste my time making negative comments, fools I just ignore.
I enjoy your videos. Im a small engine mechanic for 20 years and I have to do my own machining sometimes and watching your videos help me to apply what I see to doing it right instead of guessing thank you
Thanks for all of the very informative videos you have cranked out. I especially liked the first video about grinding lathe bits; I'll make it a point to go back and view them all. Reading about such things in books is OK, but being able to see it done by a qualified individual with explanations is great!
Thank you for these easy to understand instructional videos. They are straight to the point and I like your no-nonscence attitude.
Thanks for this video. You are such a great resource. I've been trying to figure out how to cut a keyway in a flywheel......and NOW I know. Thanks again.
👍
Great video. I was looking for a clear and concise introduction to the tools and the process, and this was perfect.
Thanks
I'm glad you made this video because I did not know how the key slots were made. Thanks.
I just love watching your vidios. You have a vast knowledge of machining and it's nice you share it with everyone.
You were just a kid when you did this video...im getting ready to do some broaching for a pulley on my 3-1 cnc mill/lathe....as usual been came to the rescue with a great video...long time listener...not a first time caller ...:)
👍👍
Thanks Tubalcain for a great demo. I've seen these broaching tools in catalogs and always wondered how they worked.
Best wishes.
Joe
Yes, it was a useful and informative video. Thanks for braving the cold for our edification.
Paul
Yes, and for me, ( a shop teacher for 40 years) its like teaching without the clowns. THANKS.
Yes--well advised. But it was so damn cold out there I was trying to get done.
I had never seen or heard of this process before. Fascinating, I had no idea that metal could be cut this way.
Best Wishes,
Brendan
Like being back in shop class but without the clown's that dont want to learn any thing Thank You For Sharing Your Vast Knowalge im learning a lot from your video's
Thank you for the great vids, please keep it up. I have been enjoying the vids since finding them 2 days ago, learning a few tips and tricks as I go. But the real value here are for the young people coming out of a school system that no longer has shop classes, here is an opportunity for them to learn how to do things and that they can do things. Thanks again.
I quite liked your video. It was thoughtfully presented in a clear and concise manner. Nice job all round. Your voice was easily audible and I appreciated the editing.
One thought, though; how about fabbing up nice stand for your arbour press out of suitable structural steel such as 2" angle iron.
I learn more and more with every video.
Thanks a lot!
Thanks for sharing! Worked in a machine shop yeas ago an needed a refresher for a project i'm working on...Thanks tubalcain!
I place this on my trestle board! ;-)
Hassay Savage , excellent quality HSS broach tools been using them for nearly 40 years.
Very useful, thanks! Now that I've seen how easy it is, I'm going to go broach a project I'm working on this weekend!
Hey thanks for the how to video. I appreciate you taking the time to do that for us.
I have been following your videos for a while, I love them, they are a wealth of information!!!
Thank you Lyle, god bless.

Rust wont hurt a file, it will, in fact, sharpen them. One of the old time ways to sharpen files is to leave them out in the rain. The way files get dull is the tips get rounded over. Rusting corrodes the metal which removes the rounded over tips.
Very good info and well spoken. Thanks much.
excellent video! Thanks for teaching the technique.
Very good info! thanks for explaining how this is done.
i would think one could make broaches and the inserts rather easily if they sets are expensive.
would hss tool stock be suitable?
Take an old or split 1/2" socket, cut the top off and weld it to your press. Then just use a half inch drive ratchet to crank it down.
I'd probably use a 4 pound hammer to persuade the broach through the work. Might not have the same smooth cutting action though.
He has another video broaching on the lathe- good info too!
THANKS
I don't mean to be blunt, but wouldn't it be better to clean those chips with a paint brush rather than rapping that brittle broach against the bench and possibly breaking it ? And maybe a big C clamp to hold that thing down so it don't slip and cause an injury ?
I do thank you for showing how this is done, good job.
Thanks for the keyway lesson.
As always, thanks’ for taking the time to make this video! And I support this site. ~M~
Excellent as always...thanks!
Thanks for watching
Very nice, I learned something.
Thanks for the video, I enjoyed learning how this is done!
lesrning something every day! :)
Thas a nice vacuum rotor. thanks for the video
@mrbreezeet1 Yes--that might work
Better to put the key way opposite the grub screw, gives the pulley more strength. When you tighten the grub screw now you will be lifting the pulley away from the key and have more of a chance of the key way chewing out. I have seen it happen many times with alloy pulleys.
Thanks
Any tips for keeping them straight?
my mechanical engineering professor told me to look this up
would like to see a shaft done. great video. I bought a set cheap on ebay. got lucky.
thanks, I never knew how that was done. Very interesting.
Tony
OT I got a few files at the flea market, look pretty new, but there is a little rust on one of them. Can I clean them by soaking in vinegar?
Thanks, Tony
very helpful never seen this , thanks
very good job! but, why don't you fix your hand press?
Thank you
Would you be my neighbor? I've always wanted to have a neighbor just like you, I've always wanted to have a neighbor with a machine shop too.
I wish I had neighbors that showed even 2% interest in what I do
Seriously I would drive you crazy asking for your advice. In the meantime I sure enjoy your videos and I'm trying to apply what I'm learning from your videos as I learn to use my recently acquired lathe.
+floyd green I'd drive him bonkers bringing broken pieces every night " how do i fix this where do i buy the tools to do it" :)
lol !!
It would be easier to have 3 handles on the press.........like on a drill press...your next project ?? good videos ...
As always a very instructional video. What would you do if you had a pulley with a damaged keyway in it. I recently purchased a used bandsaw and the bottom drive pulley has a damaged keyway in it. I was going to use a larger broach and make the keyway bigger as there is still heaps of meat left. I'm a newbie so would appreciate your feedback..... oh yeah, we have had a really cold winter here in NSW, Australia too so currently making a truck drum brake heater for my shed. Many thanks, Gordon
yes brach it larger. Then cut the keyseat larger too
total amateur so excuse me for lack of experience, but why can't u use an endmill to slot an internal keyway..??
Do the weight lock on when pressing items
baie dankie men'eer.
Hi would you tell me what size of arber press are you using
A possible alternative suggestion. Use a hacksaw on the pulley and cut straight and crisscross to simulate a broach. JBweld to snug it up.
Great Video ,Thanks For Sharing ,
@SupermaxCNC
Oh, OK Good to know.
Thanks. I'll just leave them as is.
Thanks mrpete222, I'll try it.
Tony
Pete,
I have an old Power King drill press that is unfortunately missing the spindle pulley and motor pulley. Would using a broach in this manner be the best way to make a splined spindle pulley from a round shaft pulley of the correct diameter? Or is there a better way to make a one off custom piece like this? Thanks so much and I fully enjoy what you do...imparting knowledge/experience to others of similar interests is invaluable
I have never done this. It would be very difficult to position the brooch accurately for the several different grooves
Not quite what I was looking for but nice video anyways, very interesting. Thank you
That looks like a starter rope pulley of a Wisconsin.
Suggestion? I have an older Dumont Minute Man broach set and the bushings do not have a ledge (larger diameter ring) at the top. They are just cylindrical and will pass through the hole to be broached. I ended up putting two thick washers under a V belt pulley to support the lower end of the bushing for broaching, which worked, but most of the bushing was above the pulley. Would you have any thoughts on how to modify my bushings so they appear more like the ones in your video? On eBay I did see various Dumont bushings with rings, a pin, and a circular ring with set screws. The pin seems easiest so far to me.
I'm not sure why they make the bushings w/o the ledge. all mine have it. otherwise they push thru
I will either pin it or make my own. I also can't figure why a ledge was not provided. ????
What brand arbor press do you prefer? What do you think of the Dake, Greenerd, and Famco. I believe all three are made in the USA.
I always liked dake and famco
Be careful with the broach.. it could fall on the floor and break.. and then .. dang dang dang... you put the chips out of the tool o.O
derernsti THERE'S A BIG DIFFERENCE BETWEEN EITHER DROPPING THE BROACH 3 FEET ONTO A CEMENT FLOOR- OR TAPPING IT ON A WOODEN TABLE TOP-!!!
I would take a class with you.
Since the broch could break in falling on the floor, then rapping in sideways on the bench could also break it. Next time bolt the arbor press to the bench to be safe. SAFETY! right?
@mrbreezeet1 Try 1/ black molasses and 10/ water, several weeks. 1:10
T=up
u should have ur machine screwed to the table and please buy the hydraulic press :)
Id put a nice heavy bag to catch that broach...
Да закрепи ты пресс на верстаке !!!!!!
Thanks
Ведь при закреплённом прессе удобнее и безопаснее работать . Это же очевидно.
