Square Holes - 5 Methods To Make Them in Metal

Рет қаралды 1,235,772

Күн бұрын

G'day everyone,
In this video I will be going through a few methods of creating square holes. I will be needing to machine a few of them in the future in order to repair my broken 4 jaw chuck, and after looking into some of the methods, I thought that it might be an interesting video topic.
In this video we will also be revisiting the old die filer that I used make last year. I will use it to file a hole square. I will also look at shaping a hole square and make a cutter from silver steel. I will also revisit the rotary broach tool I made earlier this year.
How does rotary broaching work?: • How does rotary broach...

You can make "reverse" files for your die filer machine. It is easy if you dont mind losing a bit of length. Use a blowtorch to heat the end of the file to anneal it (so it is no longer brittle) then just grind that new "handle end" to a round shape or whatever shape fits your machine mount. Then mount the file upside down. Obviously you can cut off the original handle end. 👍

We sometimes use the same method as Joe in CNC machines to make hexes in implant screws, except in CNC it's easier to use a one cornered tool and index between corners. It's considered a form of skive broaching. Great intro, btw.

Holding a rotary broach that way without a specially made tilted holder for the tail stock was a nice idea. I have been thinking about a rotary broach but thought it was too much work for something I would use so seldom but a chuck in the regular tool holder can be used for so much more.

Finally! I know I'm not crazy. I saw a video of the Colt factory making 1911's. They were using a "filing machine" to make the cut out on the back of the grip, the area where the spring housing is held. If I recall the machine also lifted the file up a little on the non cut stroke.

If you put isopropanol onto your file, it will be much easier to file aluminum. It prevents the clogging of the file and the finish is so much better. Equally well, I never drill a hole into aluminum without using isopropanol on the drill bit. The hole quality is like night and day.

I mount my files ‘upside down’, glued into a tube which fits the holder on the die filer. If you put the tube in the lathe Chuck, and the file in the tailstock, you can get them pretty true. Apart from then being downward cutting, the other benefit is that you can fit a handle onto them so you don’t poke your eye out 👍🏻

Here in Turtle Creek / Wilmerding Pennsylvania, USA.there was a company that made square and hexagonal drill bits. It was on Airbrake Ave. This was the home base for George Westinghouse. My math / geometry teacher had one and demonstrated it on a bar of soap. He was teaching something called a loci of points. The way the bit worked was there was a square jig, A block of metal that already had a square hole in it that the bit went into to guide it. With each revolution of the bit, the cutting edge would take off more along the square profile. At first it only cut along the edge, then it would hit the corner and the path would go along the next side of the square. If you ever saw the Spirograph toy it was a wee bit like that.

I have made many cutting tools with 'silver steel' (drill rod, to me), and all I did was heat it to yellow and quench it in oil. Sufficient tempering seems to take place during the cooling process. If I was making a drill, or similar cutting tool, I chucked the tool in a drill press and heated it while rotating before lowering it into an oil can, so it would not warp.

@ThantiK Жыл бұрын

@4:06 -- You should add some air assist to this. There's a lot of build-up of chips in your file, and getting that out of the file during each stroke would probably help it function faster.

@BasementEngineer Жыл бұрын

Making a blind hole is much more difficult, especially if only one is required. Many years ago I built a tool that required a 3/8" square hole 3/8" deep to fit a socket set handle to operate the device. A fixed handle was out-of-the-question as it would have interfered with machining operations. I laid out the square hole and drilled 1/16" holes at the 4 corners, tangent with the sides of the square. Then drilled out the middle of the square with a 23/64" dia. drill. Hand work using needle files did the rest. Did not take that long to do this part of the job. Nowadays I would EDM that hole with my shop-built machine.

@feelthepayne88 2 ай бұрын

You could also make the tool in two parts, one with the square hole as a through hole and then the other half, either a transition to round socket or whatever and just line up the holes and weld them together. Might not work for every application, but should be a useful solution for some parts.

@@mmm365 The whole point is you don't need to measure the temperature, you just get it to the point that a magnet won't attract it. This is the same point that the internal structure of the metal changes to make it hard. It will be a red heat to get it to this point.

Getting better all the time. Q: the part made at 7:20 is not the same part shown at 7:40 and onward. Its hard to see but I don't see much relief on the second one. Why the change? Using the quill that way is a very old dodge used to emulate the powered or hand shaper/slotters of old, at lease 150 years old, not a new thing. Glad you warned about over stressing the quill drive.

Did you save the metal filings for thermite? I used to work at a factory job in the 1970s where I filed the mating surfaces of a pair of tweezers. I forced the unfiled tweezers into an opening in a die where a file reciprocated up and down. I had to wear leather protectors on my thumbs and index fingers. I was paid by the piece, and occasionally made OK money for the era.
