Drilling Holes

[dirtybirdy]

I have drilled my Tugboat rda holes out to 1/8 on each side. The airflow is great but the Vapes are still super hot

I want to drill 2 more holes on each side at a 45 degree angle using a 1/16 drill bit. Then on the top of the cap I want to drill out 2 holes on either side using a 1/16 drill bit.

I do not have a drill press and can not figure out how to get the hole started using a drill. When I attempt to start it the drill bit just slides all over the atty scratching it up.

Is there some way to just make a little indention so my drill bit will stay in the spot and not move?

I doing this on a clone so I am not worried about scratching it all up just wanting to try some things out.

My current setup is 22g dual coil on 3/32 6 wraps giving me about .23 ohms.

Thanks.

Haha . . . I was going to say, no way I'm going to take a drill to my RDAs. Then I read the rest of the story.

Good luck.

ETA: I would use a ..... punch prior to drilling.

P r i c k punch or a scratch awl.
