No.. Not at all.
The clamp load generated by the bolts is what holds the joint together.
I mean, when you get it all bolted down to the proper torque, it's not going
to slide around any more than if it was a .001" clearance.

you think that .5mm is too much gap?
My gear brackets are made of cast aluminum, and my fear is that if the
legs are not tightly fit, then maybe that may induce some cracks.
Then, again, I am fairly ignorant as far as metal work is concened.

Objet : Re: KR> Main landing gears - Drilling through spring steel
Maybe a silly question, but wouldn't you be better off just using an AN-6
(3/8) fastener? The holes would already be oversized about .5mm (around
.020").
Then you wouldn't have to drill.
Just a thought.

specialists:
My taildragger KR2 main landing gear legs are made of spring steel. They
hold to the gear brackets by 4 bolts each. The bolts are metric, 10mm
diameter.
I would like to change that for the nearest AN size. That would be an AN7,
which is 7/16", that is 11.11mm. So I would have to enlarge the holes.
Now, I don't know much about steel, but I know by experience that it is
very hard to drill through these legs, since 3 years ago, I tried to drill
a couple of tiny holes to hold some brackets for the brakes lines, and I
gave up.
Questions, then: what are my chances to succeed, what kind of drill bits
should I use, and what is the correct drilling technique?
