1: when i replace the cleats on this side, how do i deal with an oversized
hole? i can't get a nut/washer into the tube as it's a lot smaller than my
hand, and far from the end. i can't thread the hole because i'd need a
larger screw (or bolt), which won't fit the hole in the cleat. the cleat


This looks like a good application for a Helicoil insert. Drill the hole
oversize with the bit provided in the kit,and screw in the coil. ( a bit of
loc-tite at this stage doesn't hurt)



2: are the threads in the other hole strong enough if i replace the screw
with a similar one to what i took out?

Do this hole with the Helicoil as well. It will mean that you can get both
screws out when , 18 years from now, you want to take it off again.

3: how to prevent further corrosion for the next time i have to do this

Before you put the screw back into the Helicoiled thread, wrap the screw
with a bit of Teflon plumbers tape.


4: how to prevent the heads from breaking off on the other side

Buy a Helicoil kit with at least 4 coils in it and do the lot of them at
the one time. It will save you alot of agrivation later.



no telling what's happened inside the tube on the other side or whether i
can get the old screws out ok. i'm sure i'm going to have pretty much the
same problems though (or something completely different).

the cleats can't really be moved as they're in the right place. besides,
if i did that, i'd have to get the other 2 screws out, causing more
problems and another set of holes.
