Exclamation Rivet help




I 'm working on my -7 Drawing 25 , Riveting the F721A-R forward canopy deck to the F-721B-R ( Longeron ).
I cant for the heck of me get any of my bucking bars in, even my little tungsten. Can I use a cherry max pull rivet in the three locations I marked in red. If can does anyone know a cherry max equivalent # ?

I used a pulled rivet, but I have no idea which one.

Default Rivet

A Cherry Max should be fine however the most important thing is that you measure the grip and use the correct rivet length.

Ed,

Pull the 721 A and B off. Then rivet the 2 rivets then put the piece
back on as one unit. I think that is how I did it.
If rivetted on. Blind Rivets.

Angry Rivet help

I used (made) a 1" x 1/2" x 7" flat bar for my bucking bar squeezed in place with fingers as close as possible to the rivets.
Then set with rivet gun.
It does not take much to set these little rivets, but make sure you squeeze firmly on the bucking bar.

I all ready have 99% rivited so I wouldn't want to remove, guess tomorrow I'll try the idea making something smaller to get into such a tight area. If that don't work I'll have to decide on which pull rivets to use


Thanks everyone for the input.

Ed

Default Blind rivet equivilent...

You'll need to verify the reach, but the MK319-BS blind rivet is acceptable.

Note: Getting them from Van's is a little more expensive that Aircraft Spruce, but ACS says the ccc-32 as an interchange for MK319-BS, but I find them a slightly different size. Get a bunch from Van's.

Default Back Rivet Plate

I've used the side of my back rivet plate as a bucking bar in narrow places like this. That may work.

Here is the perfect bucking bar for the rivets in the first post. It fits just like it was made for this spot. Several vendors carry the same one but I got mine at Avery.

Default What Bruce said...

If you haven't already riveted the assembly on, take it off, rivet the two vertical rivets, reattach and if necessary, drill the one other hole out to 7/64 and put an MK319BS in there.
