MendelMax Build Log Part 2: Tapping the Extrusions

The alumnium extrusions need to be tapped. I first used a countersink to make tapping easier:

After that, the tap can easily be done. Make sure to blow all debris out and use some oil to cut it.

The result looks like this:

 

I also used the countersink a second time to make and used sandpaper to smoothen the hole.

The overall process took about 2 hours, roughly 5 minutes per hole.
