[ARCHIVED THREAD] - How do I ''Tap'' something.

Posted: 1/15/2006 12:29:08 PM EDT

What needs to be tab is the magazine cap on a mossberg 500. Would I just drill it with a drill or do I need s weird drill bit? I was thinking i could drill the hole slightly smaller then the screw and it would go in tightly.

You have to make sure the drill bit is sized properly for the tap. Other than that, just a regular bit.

what you mean sized

The tap must be used after drilling the hole with a drill bit whose outer diameter is correct for the tap.

Too big an O.D., no or little threads.

Too small and the tap will get stuck and maybe even break. Very bad.

There are charts for this. Don't even think about cheating on drill size. Been tried before.

13th, drills are sized three different ways, fractional - 1/4" or # - #29 or a Letter - N. Using the link for drill bits twonami gave us ether find the right size in your own drill bits or as for that size at the store. And most taps should have the drill set on it.

buy her dinner and be nice. Good luck.

Seriously.

1 the tap set should include size of drill bit to use.
2 be careful to start the tap, keep it straight as possible. for every turn clockwise,back off half a turn to clean out the threads you are cutting. (this keeps from stripping the metal or breaking the tap. )

Keep in mind that if it's really tough steel you might only be able to go a half or quarter turn at a time before you need to back out the tap. Be careful because the tap will snap very easily if you've never done this before.
Everyone snaps a tap sooner or later so don't get discouraged

.
Use plenty of oil. Motor oil is a good lube for tapping threads.

Now where could I get the tools for this? I'm gonna guess home depot.
I already took the barrel bolt off.

Ok, In the directions from Uncle Mikes thing I got from wal-mart it says I need a No. 3 drill bit (.213) and a 1/4-28 tap.
This is what i found that home depot sells.

Only thing is it doesn't say the drill bit but that doesn't matter. I assume since it comes with the tap.

If the tap and bit come as a set you'll be good to go, just keep them together for future use.

Assume nothing. Save yourself some potential aggravation and maybe time, and find out first.

#3 drills are not exactly common, so I would bet that it came with the tap.

Wouldn't bet much, though.

Ok, I taped both barrel nuts/screws on both my Mossberg 500 Barrels. I got the tap stuck a few times because I didn't have a good vise. The vise was on my step dads black and decker work mate which is made for wood I believe. They both came out perfectly. This is a really easy thing to do I got a Tap set a lowes. For and a drill bit that came with a tap for 43 dollars. I think anyone with a brain could do this.

Also thank you for the info.
