throwline throw weight

[surveyor]

Say Caleb, I modified a brass plumb bob as a throw weight. Drilled a small hole straight through for the throw line and a large hole for the end of the rope. You can't see it very well in the pic, but the pointy end is rounded over and sanded smooth. I use a stopper knot on the end of the throw line and then pull it through and tie a pile hitch as you showed me near the end of the climbing line, then pull the rope inside the bob as shown to hoist. It ends up weighing 13 oz.

Nice... I'm going to give this a shot. Thanks for posting the pic.

Surveyor I see you like my choice of throwline ( target ), works wonderfully down here on my trees and I have tried them all. Hope you not planning on getting hit by that plumb bob, stay out the way. I know 13 ozs is 13 ozs however that is a dense particle situation as opposed to a throw bag. Is very aerodynamic though. Studied surveying in University so I know a bit about plumb bobs. However I like working in trees way better.

Yes you need to be careful with this weight. Also Adam,if you make one,be sure to tie an overhand knot about a foot down the throwline from where it enters the point, so you have a stopper on both sides of the weight. I have been trying to get it stuck, but so far it always pulls out. The 13 oz. seems about perfect for me, but you can obtain many different plumb bob weights.

Glad to see you found the advantages of a metal weight.

If you approach a tight fork with the PB you may find attaching another line to the end to retrieve from the wedgy.

Thanks for the tip, surveyor. I picked up a lot of 4 vintage brass pb's on ebay. It was 3 16oz and a 24. I figure after I drill them I can turn them a bit at my friends house to get them to the weight I want.

I'm interested to try them out, but I don't think I'll be using them near anyone's house. Me and the throwline don't always agree on where it should go.

I can already hear the sound of breaking glass. That would be a really bad idea in a dense urban residential area like the one I usually work in.

Um a throweight will break a window regardless.

Not from a glancing blow, don't ask how I know that. I would think a long drop onto a roof would be a more serious matter, as well.

I was able to get the Plumb Bob stuck today, although I did not wear gloves to really bear down on the throw line, but rather, I tried to finesse it out. So I used my NZ throwbag, and removed the line from the bag after each failed throw. Finally hit a very small but good target, and ascended 40' to retrieve the Plumb Bob. I found the line wrapped twice around a small upright branch and then draped over the main branch.

Regardless of what? Throw bags are softer than brass plumb bobs no matter what. Which would you prefer to be hit by? Ummmmm?

I knew a guy that used to love a lead fishing weight.. said he only ever put it through 1 roof...
