Hello.
I greet you on my channel: Simple Machine Tools
. Today I needed a tool with which I could drill holes at 90 degrees.
I looked several ways on Youtube, but none of them gave me any good accuracy.
I had to come up with my own way.
As a basis, I took the fastening bracket.
Many bloggers suggest using this as a guide for drilling.
This way you can use it where you do not need good accuracy.
I decided to improve this method a little.
To make the drill stand more accurately, I decided to weld the bushing to the fixing
bracket.
I do not have such a sleeve, so I decided to make a hole, 10 millimeters in diameter,
in a wide nut.
The drill tries to pass exactly in the center of the nut, you just need not to interfere
with this process.
I drilled the other nut on the machine, it was faster.
Now I welded both nuts to the fixing bracket exactly inside the corner.
Well, my device is ready, I just need to test it to compare with other drilling.
I fixed the corner so that the device did not move.
I drilled two holes and saw that the corner with the bushing gives a much more accurate
angle of 90 degrees than just the corner.
I'm finishing this movie, bye.
