I had an idea for a 24 inch steel pipe cut in 18mm.
If you can’t find the exact pipe, this is a great one.
You can use a 6-foot long 1/4″ steel tube.
The pipe is made up of 18mm steel, and is cut with a 6 foot long 6/8″ piece of 1/2″ diameter steel tubing.
This pipe was made to be the size of a 19 inch pipe, which I think is the correct size for the pipe.
I like to use a flat side to make it easier to cut, and a flat top to allow for the bottom of the pipe to go on the end of the cutting board.
Here is the finished 24″ pipe.
