Nice! As soon as you said it wasn't deep enough I thought 'luckily you have a broach that fits that if you turn it around'. 😆

1) I've always wanted a broaching set. This one looks pretty cool. 2) Looks like rebuilding your shop press to be more usable can be a whole series of new videos. Make it less sloppy, add air over hydraulic jack (or can you modify the current jack?). 3) Regarding building up your shop tooling, using your brain and whatever tools you have until you have the right tool, My first "lathe" was a drill press and a few different files. Took forever to shape something, but it worked.

I love my broaching kit, even though I’ve only used it twice. It’s a must have.

I have been watching the prices on this tools for years. Thanks for sharing. Your going to love the air over hydraulic pump. Next for me is a press brake attachment. I saw a video years ago on rigging up the release valve with a foot leaver, it is the best. I used my press to flatten the end of conduit for a geo-dome. That a lot of pressing. Four hurricanes later it’s still going strong.

When using a press with H motion slop (vs arbor press) it’s highly recommended to relieve pressure on the ram intermittently to realign/correct misalignment and reducing the chance of breaking your broach. Slow and steady does not compensate and when you’re driving a 20 ton hydraulic pump there is no way you’ll feel anything on the other end.

The groove is cut deep enough as long as the broach slides into the corresponding hole. In fact it should not be recessed, otherwise you may end up with a broach that start with an angle when the first tooth bite, and that's the quickest way to break it.

Make yourself some arbor extensions the same diameter as the arbor on your press in increasing inch long increments out of mild steel. Turn, or silver braze, a collar on each one that slides over the existing arbor to keep it in line when in use with others or the existing arbor. (If you are going to turn a separate collar you need to start with larger diameter stock and own a lathe.)Imbed a round neodymium magnet in a counterbore on the large end of each extension. The magnets that come with a countersunk hole in them work well for this.( The counterbore should be just slightly deeper then the magnet’s thickness. The magnets are brittle and you do not want anything pressing on them.)You now have a set of extensions that link together and keep you from having to move the presse’s bed up and down all of the time. While you are at it, make yourself a storage rack that holds each one that angles down towards the back side of the press, and mount it in the upper left hand inside corner of the press. The collars then retain them in this rack thanks to earth’s gravity. In that way they stay with the press and don’t get lost. When you are broaching a keyway always stop a couple of times, take the workpiece out with the broach still in it and look at the underside where the backside of the broach is suppose to be making contact with the collared bushing. In some materials the broach starts to dig in and pull itself away from the slot in the collared bushing. If you continue in such a manner you run the risk of a tapered slot and, or, a broken broach. I would recommend that you always use the jack handle that came with your press for broaching. It gives you what may be termed “machinist’s feel” for the entire process. You may want to shorten it up over time as you use your press. Save the air over for press fits and the like. Unless you are broaching 500 pieces, you do not need the speed.

This probably sounds crazy, but I’ve had a lot of luck making broach guides by 3D printing them. Just an FYI in case you find yourself trying to broach an odd sized hole.

Excellent review! I too have wanted to add a broaching kit to my arsenal for years and you may have just convinced me to move forward with a purchase. 👍😁

Looking for a set of broaches, mostly for square holes, probably also some key ways. First good review I've seen thanks man. Subbed.

Been wanting/needing this for my arsenal. Hope someone sells some perches soon since I just bought this. 🤣

Hi, algorithm just stumbled me onto your very nice channel. I've had a look through the back issues and sub'd. I like the gentle humour (ok, humor!) and the down to earth practicality. I was just looking at the lathe clutch - I don't need one but I like seeing sound engineering - especially when there are follow ups about improvements. Incidentally I built the James Clough ELS and it is excellent.

If you ever want to mill the jig deeper or wider a good trick is to put the broach in the jig inside the mill vice and indicate on the broach to get it squared

A needed mod for your press would be: quick change variable length posts for under the ram, would make for much less changing of the pin on long stroke pushes like that one was

You should have put the small bushing in a matching hole and made sure that the broach was actually too large before modifying it. The smaller OD of the bushing means that when the slot was cut a larger percentage of the diameter was removed. Possibly the answer would have been to just chamfer the sides of the pilot section of the broach.

For comparison a plain 3/16 broach with shims from AliExpress was $20 delivered and worked well for about 9 steel spur gears I made. Maybe the same factory, who knows? I wouldn't be too quick to buy a set unless you do a lot of that kind of thing.

Make sure you have padding on the floor underneath the press. If the broach falls through and hits the floor your nice broach will be in two pieces.

The best way to had the depth of the 1/2 bushing is to mesured it with the broach inside. Total height with the spacer should be .560-570" f

Nice informative video, thank you! Just one FYI, is that an older model HF press with the cast iron, aka "exploding" press plates? Check into it, be safe, thanks.

Isn't using that broach like a file the same as turning a reamer backwards when you reverse the stroke. The cutting edge isn't supported and will dull. Not sure, but I would avoid using the broach in that way.

great review

If you had used an already broached piece and turned the cutter around, it would have come out perfect.

Ya know you can pull the pin down manually and adjust the big gap out with the screw on top of the jack.
