I have a selector i'm trying to put the dimples in and I can't seem to even start a hole. These things are tough. I don't really feel like ordering one of the repros right now.  Anyone got any ideas?

I'd say contact heatnbeat, he's a member here and ask him what sort of drill bit he uses.

I tried the same thing. Gave up and went with JS aka Heatnbeat. The drills required cost a goodly portion of the $25 he gets for his.

Save it for a later retro build, one where you don't need a dimple.
Get a Heatnbeat dimpled selector.
If you can't afford ia repro, then use it without the dimple for now.
Replace it with a Heatnbeat when you have the spare cash.

Selectors are very hard to drill.
Not worth it IMHO.
I have 3 real dimpled selectors and a couple of Heatnbeats and his look very close.

cobalt drill bits and plenty of oil.,start with a small one to get you a pilot hole then use the size you are wanting for the pin hole

Well I tried drilling it with a cobalt bit. All I did was remove some of the park on it.

Should I try to use a center punch too?

I was taught in shop to center punch everything before I even thought about drilling it. On most things, we'd use carbide center drills after punching it before actually getting out the drill bits and going to town. Granted, we also had drill presses and vertical mills to use... I miss shop class.

Anyway, I'd imagine the same would hold true. Center drills are expensive though. I would at the very least, beat a good spot into it with a punch before attacking it with a drill.
