Three Ways To Cut Keyways! No special tools!

Glad to see you broaching this subject.

I did something similar in 1991 while underway on a submarine in the Atlantic (we had to repair a large pump and needed to manufacture a part). We did not have any fancy broaches but we did have an old South Bend lathe. I ground down an old style boring tool to make the cutter. It took a minute to cut the keyway but it worked just as well. Nice tips, Quinn.

As always kudos for showing alternate methods and work around from the expensive specialty tool. One of many reasons your content has such value!

Great video content and I applaud you for warning users of long keyway broaches to frequently release the ram pressure from the top of the broach to prevent accidental breakage. We were taught to always relieve the ram pressure every couple of teeth of broach travel.

Your voice delivery and correct terminology use is flawless! Perfect video quality. Thanks also for presenting the cutting audio from broach or cutter passes...it is the sound of Victory!!!

I have found that if you use carbide when doing the mill/lathe trick you have to retract the cutter before returning, otherwise the cutting edge chips. HSS seems to handle dragging on the return stroke much better.

I've zero interest in making a steam engine, but I love the things you are teaching me while you make one. Same thing here: always wondered how one could cut a slot (in this case, a keyway) on a machine that spins material! My lathe is so much more capable than I am, but you're teaching me to THINK. Very grateful for that, Quinn. Press on!

Quinn, From an engineer and machinist, you know your stuff. Well presented too. Good job.

You can also use a file. It might be more labor intensive, but after after a week or so you'll be halfway there!

And here I am 7 months later for a refresher course. My 16-year-old son needs a key way on a generator pulley on a 49 Plymouth.This will be life changing for him!

I am working on a workmanship program in our company and crossed ways with your channel. I am VERY impressed about the depth and effectiveness of your teaching. doing metal works for 30 years I find all essentials and more covered and super well explained.

cheers for this video Quin, I was aware of the methods for cutting a keyway on a lathe or mill, but it was really good to see it explained in terms simple enough for me to understand and have it demonstrated so I can follow along!

Thank you for sharing your experience, knowledge, humor and skill with such calm and accurate commentary. Great job!

As a newby to this engineering & lathe type stuff, I found this really helpful. Thank you!

I really appreciate your idea of what 'expensive' is. So many sites/channels I visit have a much different definition. I watch/read for some time, and then find out that this great part/accessory/thing I'm finding out about will cost more than I spent on the machine I'll be using it in. Or the tool I need to make the thing costs far more than just buying the part, or dozens of them. It's true that, sometimes, that's okay, since making the part is the goal, but getting these great tips is so helpful, because I have very little cash to spare!

Brings back memories, I have used all 3 you're methodes .Your'e guidance is good, I was a tool and die maker for 40 + years

The true test of knowledge is one's ability to share it in a clear and simple way! Thank you for sharing your knowledge! I love your humor "for the vitamins, kitty hair, because we're civilized". Priceless! This very old guy appreciates it very much!

Those are some great tips to keep in the back of my head. When I first got started in this stuff, I worked at a machine shop mostly doing operator stuff. They got a job that required a ton of keyways. They went out and bought a vintage keyway machine and had it refreshed by the company. I can't remember how many I ended up cutting. It must have been in the thousands.

Every Sunday morning (Australian time), your videos make me 18% less sad!

I like your comment on the lathe. An old machinist told me the biggest limit of what a lathe can do is the operators imagination.
