Thanks all for the comments
Having been around the Matronics lists for more than a few years, I'm fully
aware that I am not building a space shuttle.
So much so that I have returned the silica bricks (except a few that I kept
to repair the fireplace) and cancelled the solid fuel boosters order.
Seriously: what I described is quite simple and does not add to the
workload.
On the contrary, I strongly believe that it saves time by avoiding glitches
and associated head-scratching. I have used this process in the wings and
tail feathers (all done) and fuse (past "boat stage").
Happy building
Carlos

I don't know what you guys are building but I thought mine was a space
shuttle! If you look at page 6-MT-1 through 6-MT-12 these are the
plans for mounting your plane to a 747 to transport to and from your
home airport.

The corresponding drill bit is 0.160".
A black cleco is 0.149" at its widest point - but it is not
round.
(Note: these are measurements I took from Items I have. You may
find slightly different measurements.)
In longer parts (more than a foot or two) or assemblies of more
than two parts, I find that if parts are not perfectly aligned, it's
hard to insert the rivets. And, worse, parts will be warped or difficult
to match as I proceed with construction.
So, instead of simply trusting the clecoes, I started adding
spent drill bits here and there (a solid rivet is better than a cleco,

I eventually started cutting drill bits and grinding one end to
make it easier to insert them.

The opposite end is covered with masking tape - see attached

I have a bunch of these, A4 and A5, and use them frequently.
Hopefully this can be useful to someone.

Carlos:
Don=99t let anyone discourage you from trying to achieve
perfection when building anything.
When you are finished you don=99t have to explain any misfits,
wrinkles or misalignments.
