Off the wall question - I'm thinking of "ornamenting" a motorcycle plastic part with some fired 9mm brass.

 

Anyone happen to know what drill size would make a hole in plastic of the right size so I could "press fit" the brass in the hole, leaving the end of the case/primer visible?

 

Ideally the hole would hold the case tight enough that it wouldn't fall out, but not so tight that I'd risk breaking the plastic trying to press the case in.

25/64"

I measured a spent case at 0.388 in. 25/64 would be the closest, but it wont be tight enough for a press fit, a bike would vibrate them loose, but a little epoxy or something would work

Hrmm.  Any "home depot tool bin" way I can drill something closer in size?

3/8 bit would get you to .375. That might work if you ream the hole out a little extra with the bit. Not sure how thick or elastic the plastic is but the 9mm has the extractor groove and lip that can make the casings apear loose.

Thanks - my plan was to leave the extract groove portion above the surface of the plastic, not flush with it.

be aware the 9mm is a tapered case, it doesn't look it but it is, .380 at case mouth to .390 or so at the web. The rim itself is wider still.

 

 

 

Nice !

Looks good, should drive the DC popo BSC if you ever visit there.

Trimmed down all the cases so they're really just the end of the case.  Since they're not complete cases will that clear me of the DC nonsense?

Who cares, lol. That came out great.

should have polished them up before putting them in 

 

Other than that, it looks good 

Id avoid DC altogether!!!!
