.010 deep in a .120 part should not be a concern at all. I don't know the part your riveting in detail, but I built a -4 and specialize in structures on heavy jets. If you have access to both sides, you can shoot a universal head rivet in the opposite direction and the bucktail will "fill" the countersink. Done and move on. Or, if your parts have edge distance to oversize, simply go the next diameter larger..plenty of material there. In fact you could probably leave the countersink you have, enlarge the hole, and shoot next larger rivet, then shave/sand the remaining rivet head material away.
Is there space where you could drill another rivet hole? (but not closer than 2 diameters away)
Rocky, please see attached.Can you post a picture?
Scott, the rivet is a 4-x. Yes, the CS is on the top.What size rivet? Is this CS material the "top" part of the stack...?
Ralph, I don't think so.Is there space where you could drill another rivet hole?
Jeff, not even close.... is there a knife edge....
Bill, that's what my gut said, but we're trying to be careful and deliberate.... should not be a concern at all.
Wow. Sounds ridiculously obvious and simple now that I see it in writing. To be honest, this never even occurred to us.If you have access to both sides, you can shoot a universal head rivet in the opposite direction and the bucktail will "fill" the countersink.
Bill, Again, wow. This is not something we would have come up with ourselves, but sounds elegant. We have not measured the dimensions, but believe this would also work.Or, if your parts have edge distance to oversize, simply go the next diameter larger..plenty of material there. In fact you could probably leave the countersink you have, enlarge the hole, and shoot next larger rivet, then shave/sand the remaining rivet head material away.
Scott, We had thought of that but lack the tools, and probably skills to do this one.A third one that I have used myself in the past is to make a fin spacer that can be put on top of the manufactured flush rivet head when you set the rivet.
