What's that tool called...

...that you use to drill hole in bolts for safety wire or cotter pins?

I don't even know what it looks like or what to ask/search for, but I have a few things I'd like to run a cotter through!!

 

I use a clamp and a drill

 

I call it a drill press.

 

drill jig.

Drill bit!

 

its a fixter that holds the bolt while you drill it in the drill press,i found it easyer and quicker to just buy the bolts that already have the holes .

 

I use a V-block with a clamp !! >>>>.

 

I use loctite

 

I don't drill the nuts, I like using castle nuts. That tool looks neat, I just don't do enough to justify it. I use a piece of angle iron, 2 clamps (one for the bolt and the other for the angle iron), and a drill press.

 

Looks like this >>>>.

 

Those jigs kinda suck(the store bought ones). You will break bits.
Put the bolts in an alum. vice.
I use an electric drill w/ a 1/6 or 5/32 bit only hand tight so it will slip and not break when going thru the other side of the bolt.
I've drilled 1000's of bolts this way, maybe 100 thousands.
You will still break some though.

 

I was talking to an aircraft restoration guy one day about drilling bolts and nuts for safety wiring and he said if it's something that is that important to keep tight, by a bolt that already has a hole in it. I believe he said Aircraft Spruce sells them and several different grades. Also, McMaster Carr will probably have them as well. I can understand not buying that fixture if you're only going to use it a couple times. So if you're only going to do this a couple times just buy the correct bolts a couple times and save yourself time and money all the way around.

 

Problem with that Scooter is the differing applications. I need the hole where I need it, not where someone else put it.

 

Well I feel like a dumbass, I figured the bit would want to wander all over the place. I'll have to try it that way then...

Thanks guys....

 

Anything you are drilling a hole take a center punch first so drill hole starts true and straight where you want it and plenty of lube while drilling.smaller holes are always more of a pain ,just take your time.

 

Yeah, that is true. That can be an issue... Hate it when that happens!

 

Start with a center drill- they are stout so they don't wander. The next, regular drill bit won't wander- in other words, it makes a better pilot hole.
