It's not a radiator, it's a colander! I can't fix it... We have four holes and I couldn't find any of them! The good thing is that these radiators are available on the aftermarket in sufficient quantities at a reasonable price! Glad the other radiator is OK! The rad adapter also looks bad. But at least I can correct that.
Cutting, punching, drilling, threading, fitting... By the way, I broke my set of taps. They were both left in the holes...
Drilling accurately through the aluminium from a side you can't even see was bloody difficult, so there won't be any photos of the process. I'll just give you the final result.
The tap wrench is actually awful for smaller taps. You always put too much stress on them. That's why I use the drill. You can reduce the torque, and if there's still too much stress, it slips in the chuck instead.
By the way, when I was looking for a small sheet, in my aluminium warehouse, I came across some old concepts The inscription in ru "In the event of a fire, press the button" I should have benefited from this experience...
I have filled screw holes in my projects too. I am famous for getting the radiator mount holes wrong. The scrap bend is great, but your current curved bends are cooler.
Well, I'll show you a rough plan of action. ghm - the pumpster I love this moment! It's time to install psu attachment. Amazingly, I hit the holes the first time! I didn't even have to redrill anything!!!
Nicely done. If I had used a router, some of those slats would have bent. In fact, the only time I broke a router bit was cutting aluminum. The chips all got under the router base too. I may just have a crappy router.
