Today I first riveted the three ribs I had prosealed yesterday. Then I riveted the outboard end rib. First I riveted the nose reinforcing plate (the 6 rivets on the right), then I squeezed all the rivets. I surely prefer this method of riveting, but the proseal having had no time to cire I noticed it makes quite a mess.


Then I did all the fillets on the ribs and covered the rivets. I finished by installing the vent line.



Here is a picture of the pick-up bay with the vent and return line. I'll rivet the inboard rib later as I'm still missing some tools to torque the nuts on the lines.

Today I riveted the ribs I had prosealed yesterday it goes like this: uncleco, clean the hole with a deburring tool and acetone, put some proseal in the dimple with a toothpick, put in a rivet and shoot it. As the proseal holding the ribs is already cured the rib stays in position, and as the only uncured proseal is the small amount in the dimple, the work is not messy at all. I noted that some rivets are standing a little proud of the skin, I drilled a few out and replaced them. I will deburr the holes a bit more.
Then I prosealed three other ribs to be riveted tomorrow.
As usual all this finished with a clean-up

Today a begun prosealing the ribs, I opted to do this in two steps. I prosealed the rib, then put a cleco in every hole (I even added a small nut between the cleco and the skin, it gives a bit of a better grip). I will let the proseal cure overnight and then rivet everything tomorrow.



Here is an inside view, tomorrow after the riveting I'll have to thoroughly check the flliet's integrity.

This morning I riveted the right tank stiffeners. Being a bit more careful and organized, allowed for a much cleaner work. I finished by reassembling both fuel tanks, this will allow to begin working on the ribs next time.

Today I used ProSeal for the first time. This two part compound needs to be mixed in accurate proportions, then has to be used within two hours as it hardens slowly but surely.
I first tried a very small quantity (20g+2g) to get familiarised with the product. To me the compound didn't seems as free flowing as I had thought but it is surely tsicking to everything it sees. So I'm working with latex gloves not to get it on the hands, but it's impossible to keep it of the tools.
I first installed the stiffeners using the following sequence: first a bit of proseal in the dimple, then the rivet in the dimple, then the stiffener get proseal on the contact flange, it gets put into position and back riveted. The proseal oozes out from everywhere, but before cleaning, nice fillets are formed around the stiffeners and every rivet get a blob of proseal on the factory shop. Here is the result



After the stiffeners, I riveted the fuel caps, not forgetting the vent line attach clip.



I also riveted the drain valve support. To be noted the free path between the proseal blobs on each rivet to allow water to go all the way to the drain.



Today I did all this on the left tank, on the right I only did the cap and the drain before cleaning the tools and the tank skins.
