Using a PCB board as a drill template for heatsink holes. The 4m screws screw into the heatsink to hold the template in place for starter drilling.
Notice that there are 4 extra holes that have been tapped 6/32 for a little extra security and also to help align parts and keep from rotating.
Each screw is inserted between the heatsink fins all the way to the flat portion and can be changed easily if it were to break on assembly.
Ignore the exposed holes seen in the flat of the heatsink, they are old positions no longer in use.
Only fitted, not assembled just yet.

Nice, the tip for enlarged printout! To be honest, with a hand drill, I was never able to have 4 aligned holes, most of my boards ended up screwed with three bolts instead of 4. The third/fourth one just always ended up misaligned.
Bench press drill is probably mandatory for me there to get precision.
