Something that has worked for me is to insert the tail (smooth) end of old drill bits in some of
the holes, to ensure parts remain aligned. A piece of masking tape on the drill bit will help
keeping them in place (they tend to sneak away when you are not looking).

At our Basic Sheet Metal Workshop at SunNFun we teach that Clecoes alone don't completely hold
critical structures in alighnment. I always urge builders to use at least a few critically
located clamps to maintain important alighnment. This is true especially after all deburring
and prep is complete and riveting is about to begin. If your have a wing laying on a table with
clecoes in every other hole, I can lift one corner of the wing off the table if your firmly
hold the oppisite corner. Ask me how I know that you can build a warped wing this way!
With proper clamping, you can remove many of the clecoes and use them elsewhere in your
construction process. Of course there is nothing wrong with having a clecoe in every other hole
when you are riveting, but if the structure isn't properly aligned AND CLAMPED it will come out
warped. Again, ask me how I know!
Good luck and build straight!
