[TPR] Drilling bolts for Safety Wire

[Asa Jay Laughton]

Well -that- was an adventure.

I picked up a drill fixture for making holes in bolts to pass safety 
wire through.  It was this one:

As you recall, last week I broke the first bit on the first hole.  I 
picked up a couple of super-razoo bits (Carbide I think) and took to my 
Dad's drill press today.

Long story short, I think we went through six bits total before we 
called it a day.  The second original bit actually lasted the longest.  
One of the new super-duper ones I think was dull to start with as it 
chattered and shattered almost immediately.  The second one cut like 
butter, until I hit a piece of broken drill bit from a previous snap 
(yea, we thought we got it all out of the hole but apparently didn't).

I now have six caliper bolts with two holes each, and two caliper bolts 
with one hole each... and small bits of broken drill bit in second hole 
attempts. <sigh>

Doing it again... I'd recommend just ONE hole per bolt.  I wanted at 
least two for more flexibility with the safety wire.  However, my Dad 
commented later that I really only need one and we talked through how to 
properly safety wire based on all possible positions of the bolt.  My 
dad is a certified A&P so I figure I can listen to him (well that -and- 
I'm older now so listening to Dad is okay).  He was lusting after the 
drill fixture too, he told me there were plenty of times he'd wished 
he'd had one when he was working on planes.

Overall, mission accomplished... I just need to pay back Dad a few new 
1/16" drill bits.  :)

PS.  It's damn cold here, raining cats and dogs too.  I've forgone any 
more work on the car today.
