They truly are different products. Alumifoam is the same density as Cedar Wood. At .47 grams per cubic centimeter, it means that for every cubic centimeter of Alumifoam you need .53 grams of weight just to make it neutrally buoyant. I cannot copy a link from our own web site right now, but hopefully the following link will show up soon. If not, do a search for Archimedes Dunk Test on this site and you will find the link. Do the dunk test and it will tell you how much volume your lure has. The volume is equal to the same amount, in grams, it will take to make the lure neutral. Lets Call that variable A. Weight the lure and see how much it weighs. Lets call that variable B. Subtract the weight of the lure, B, from the total, A, and that is the minimum weight you must add. Adding more will make it sink. Ok so is the dunk test done without weight hooks or anything? The link didn't really say. Do I mold just the foam bare to do the dunk test? I'm confused a bit.

Anglinarcher Posted October 20, 2017 Report Share Posted October 20, 2017 A "breaker" of water was a typo. It should have said a beaker. What you need is anything that is large enough to hold enough water to submerge your lure in without touching the sides or bottom. You need a gram scale large enough to weigh the weight of the water and the lure. The Dunk Test will work for several things, so you don't always need to have hooks and hangers attached. BUT, in your case, where you are trying to sink a lure, you want everything attached. I will do a quick video and attach it if I can. It should show you what I am talking about.

Anglinarcher Posted October 21, 2017 Report Share Posted October 21, 2017 OK, can attach pdf, jpgs, etc., but not movies. I don't want to post a 2 minute video to YouTube, so I sent you a message. Give me your email and I can send the video to you. 1 Quote Link to comment Share on other sites More sharing options...
