Clecos - Every other hole?

rodcritt · #1 10-07-2008, 07:47 AM

When match drilling the skin to the HS is it OK it put a cleco into every other hole or is it necessary to place one in every hole? I would like to drill my skins tonight but I only have 100 clecos and it takes 113 per side on the -7. I know I need several hundred more clecos before starting the wings. I just want to move on before I have to order more. Is this a bad Idea?

Thanks for any advice,

If even that! Every fourth hole would work just fine.

I did not cleco any of mine together until rivet time.
And even then it was sparse.
I didnt match drill.
I dimpled right out of the box and assembled to rivet.

OMG! You're going to fall out of the sky any minute now! Did you at least prime everything in sight?

Hmmm. That'll make the next one go together faster!

Rodney,

Every other hole will work just fine.

Kahuna has one nice plane and it will be interesting to see it when he has 2000 hours on it. It might turn out that he was smarter than all of us but until then, I suggest you stick with drilling and deburring per the plans.

Thanks for all your help. I didn't think it would do any harm. It's just the reassurance I needed.

If prior history is any indication, we probably won't have to wait very long.......

I suspect it will look as good as it does now.

What is the chance of a crack developing if you dont drill and deburr ?
I kinda feel the drill and debur is there to fill the 51% rule. Sure it makes good scientific sense to drill and deburr before dimpling , but will it really make a difference in the first couple of thousand hours if you dont ? Any experts??

Time to be dealing on used clecos from those that are finished.

You will also end up throwing some away during the build process such as tanks and fiberglass work. Not many but some.
