I'm planning to put up a bolt ladder soon and would like to add a couple rivets for spice however, I don't know how they're placed.

Something like this?

Pop rivits work best.

You drill a very small hole and put the pop rivit in, leaving just enough sticking out that you can place a loop of 130 lb monofilament around it, right behind the head. Then use the pop rivit tool to expand the rivit until the shaft breaks off. Attach a carabiner and viola! You will be a riviting fool in no time flat.

I agree whole-heartedly with Brian. If you must drill the rock, to make it more dangerous and less permanent is just irresponsible.

Please don't place garbage gear that will need to be replaced in a few years. Please heed Brian's advice.

Apparently Mike is the only other person who thought this post was as funny as I did, but he had a better reply... If the OP is serious, read Downward Bound.

About time someone brought the rivet back.
Good work Dugan, ol' chap.

(Oh, and btw, you should use a 137 lb monofilament. . . let's not be irresponsible)
