Can't have enough
I keep my cleco's in tubs, one for 1/8" and one for 3/32". I've had both tubs close to empty a couple of times. When riveting the horizontal satbilizer, I was putting 3/32" cleco's in just about every hole or every other and that ate up a lot of them (sorrry, I can't say how many were left in the tub). I also had work going on the rudder at the same time and had a few in use there. I've got a quickbuild fuse and wings now but I'm still on the emp.
I bought the RV Builders tool kit from Aircraft Tool Supply and that was the number that they had shipped. I've also tossed out a couple along the way that went bad. I just figured that someone else had figured out, more or less, what was needed. I'd sooner have a few extra than not enough.
