Cutting Internal Keyways in Manganese Bronze Gears on the Vertical Slotter - Manual Machining

The Morey Vertical Shaper or Slotter as some call it, keeps earning her keep. This particular job came in due to one of my other videos on cutting keyways with this machine. The customer was push broaching these, and it was not going well. They told me the last set they cut, the broach exploded, making a very dangerous situation.
As this is the first test run of these parts for a potential new customer, I need to do my best. Not that I would ever put out anything other than perfect parts.
The Kool Mist unit was purchased from KBC Tools and I am very pleased with it. Their products and pricing are great. Here is the link to the Portamist. www.kbctools.com/itemdetail/1...

I love these old machines . In the 70's I worked in a foundry that had a Turret lathe with a 10" bed next to

[@BrucePierson]

These old machines sure do a good job and keep on keeping on after decades of use.

I got a vivid mental picture of that exploding push-broach fragmenting across the customers workshop. Not surprised they decided to outsource that step in the process. Looks like you have the right machine and tooling for that job. Hopefully the customer brings in more work.

This is like the earliest asmr haha. It's something the cnc machinists miss out on. Hitting your number is like getting a hole in one, sinking a half court shot or catching a 50 inch musky. The simplicity of the machines action hides it complexity and sturdiness of build. I'm gonna have to start looking for one. Great vid and channel. Thanks again

Love that old machine. Maybe it was just the camera angle, but it looked like the second cut was a goo 60 thou off center of the first one.

Glad you mentioned the flaws with force broaching. I was curious about how that would work. I agree that using a coolant misting system is a lot less messy. I have to say though that I did get annoyed with the constant hissing when I was working as a machinist.

Spray system seems to be a great idea. Thanks for another great video, machining without CNC done right.

[@Rustinox]

I can totally understand you like this machine so much. I'ts a very nice piece of equipement.

My back hurts so bad just watching you leaning over to run that.

[@hl8256]

That is a magnificent machine.

[@waynep343]

I see a base plate jig indexed and bolted to the table with a precision bore the same as the part but cut outs where the broching head as to pass thru so a plug could index the centerline. Adjustable stops to hold the clock position of the part while you clamp it down. If you could get a chunk of the worm gear. You could make pivoting indexing locks. So you clock the part to seconds of arc everytime in seconds while clamping the part.

I remember being around when my boss was trying out a new tool and his dad came in, He showed his dad the result of the tool on a fence post but his dad was more interested in the shavings that came off the cutter...picked a few up and because they were shiny smooth and spiralled said "that'll do" and walked off to do something else...

You did a nice job on the video and the part. It is interesting to watch you. What a great idea to cut it in two steps. I was thinking of you and the tractor show but that is next month. Thanks for making and sharing the video. I am glad that you are finding new customers. I wish that I could stop by and see you sometime.

[@mikedyson7330]

Great video , need more.

[@daleolson3506]

Does it matter where the key way is in relation to the gear?

[@JonesMetalCraft]

Very cool machine!

[@kimber1958]
