Drilling tight spaces
Posted: Fri Feb 17, 2012 8:55 pm
Thought I would share a dilemma and solution I came up with today. I needed
to open up 4 x 5/16" holes up to 7/16 holes in the top of the carrythrough
for the outer gear saddle bolt crush tubes. I had only wanted the tubes to
be held in place by the top and intended on leaving the bottom at 5/16" to
add an 1/8" thick layer that the bolts/crush tubes would have to pull
through to make it a little harder to "lose" the gear. Now I now why MAM
drilled totally through the carrythrough tubes, as they could only do so
easily from the bottom! With everything riveted together, door sills
together, etc, no flex drill or 90 degree angle drill capable of holding a
7/16 bit (or 3/8" shank unibit) would fit in to get at these holes in such
tight quarters.
I found a use for one of those Christmas presents, from the kids, that I
always get accused of never using. As seen on TV "squeeze wrench". I ground
3 more flats on my unibit so it would fit into one of the adapter sockets.
Put it in the squeeze wrench and while pushing down on top with a piece of
wood, spent 45 minutes ratcheting in 4 holes. Not quick, but it worked!
