Question

A hexagonal hole of each t.......

Answer 1

Answer:

Step-by-step explanation:

Step 1:

In this instructable, I will show you how to make a hexagonal shaped hole in metal. The reason I'm making this is because their is little information on this topic. This is not a very costly method. I hope you enjoy.

Step 2: Tools

You will need:

- Drill bits of the size of hex you want to make  

- Allen key of the size hex you want

- Bench grinder  

-Bench vise or some sort of shop or arbor press

- length of pipe If you're using a bench vise(for leverage)

- various sockets to use as a spacer

- drill or drill press

Step 3:

 

 

 

First you are going to drill your holes. I recommend using layout fluid and a scribe to locate where you are going to drill. I used a center drill and a mill to accurately drill my holes. A drill press will work too. Tip: I recommend using a drill but that is a little smaller than the size hex you want. You can use the exact size, but a smaller drill will leave a sharper hex shape

Step 4: Making the Tool

 

 

 

This is the key to making a hex shaped hole. You need to get an Allen key that is the size of the hex you need. You then cut it down to about 2-3 inches. You then need to put a taper on one end. You do this by using a bench grinder. You grind on each flat of the hex, try to keep it as even as possible. You then need to add rings around the whole tool. You can do this by using the side of the grinding wheel

Step 5:

 

 

 

You now lay up various sockets to support the work piece in the vise. You then put the part and the tool in the vise and add a little pressure. You can tweak the straightness Of it with a hammer(lightly). Put on eye protection!!! I am not responsible if you hurt yourself doing the upcoming step. Be careful. You now tighten the vise. You'll probably want to use a pipe for leverage. Tighten until the tool is all the way through the part.

Step 6:

 

When the tool is all the way through, take it out of the vise, and beat the tool out of the hole with a hammer. You can then repeat this process on the other side to make it sharper. After you're done, you'll want to debur the hole. You can use an angle grinder with a flap disk to do this.

Step 7:

You may want to clean the hole up with some small files. And now you have a hexagonal shaped hole in metal!! The part in this instructable is 3/16 steel. The tool is a 3/8 Allen key.
