Drilling holes in tin cups for a sculpture project-?
Question:These are cups like one would use in camping-I think of them as cowboy cups. If theres a bit of chipping-its ok as I want them to look used-even rusted in places-so I'll probablt try and chip some. I've got an extra to play with but was wondering what type of drill bit to use? Just a "metal" one? THANKS!
Answers:
The thing to do is to use a small grinder bit like the kind used on a dremel. Slowly gring the ceramic coating off in the area that you need the hole. I suggest using a marker to draw the exact diameter of the hole and placement. The tough part will be getting the same spot on both sides but if you don't care about the inside, all the easier.
Once you get the ceramic off and are at the metal, use a sharp bit and you should get the perfect hole with no chipping.
Make sure the grinding bit you use is not too rough or it will just chip it all off instead of grinding. I have actually used one of thos bits to grind a hole through a glass pane. It took time and patience but it can be done.
I was trying to do the same thing, I was making a wind chime with a metal cup.. .it doesn't even seem like that thick of metal and I tried metal bits and steel bits... couldn't get through... good luck to you though... I am sure there has got to be something!
I would use a metal punch to punch the holes in it. Fill the cup with water first and then freeze it. Then punch. That way the cup won't deform.
If you don't care about chipping the enamel, why not just punch the holes, with a steel punch and hammer?
A cheap punch is a drywall screw. Pierce with a screw and widen the hole with a tapered steel punch, or nail set.
Just a regular metal twist drill.
