It has a hole in its "face" and a hole on its back. As far as making one from wood I am sure it could be done but it would present some unique challenges like how woule you bore the hole and if you had the hole bored how would you apply the sealer and epoxy with a straight handle brush. Just my opinion but too much trouble for me for what it would actualy be worth. Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted January 8, 2010 Report Share Posted January 8, 2010 A few members have messed around with this idea. I recently caught Pete (Hazmail) out with such a design, on another forum. I think Lapala also did some work on this idea. I bet Daimei has something going too. Searching will be difficult, so hopefully we will get some feedback.

hazmail Posted January 9, 2010 Report Share Posted January 9, 2010 (edited) Sinyo - the perfect material for this (IMO!!) is Expanded PVC board, you can drill the tunnel and you won't have to seal it, as PVC is pretty much impervious to water.pete Edited January 9, 2010 by hazmail Quote Link to comment Share on other sites More sharing options...
danderson Posted January 10, 2010 Report Share Posted January 10, 2010 I've always wondered about this as far as a lure making bubbles. It seems to me this can only work if the lure traps air before it is submerged or it is a topwater lure that is continuously trapping air as it moves across the water. The reason I was wondering is it would cool but I just don't see how it would work once the air supply from the cast is replaced with water as you retreive it back to you. Just curious I guess if anyone could explain or if I'm way off on what you guys are trying to do. Quote Link to comment Share on other sites More sharing options...

And no problems with sealing. Quote Link to comment Share on other sites More sharing options...

When the water passes through the holes, it's slowed by the walls of the hole, and so it's under lower pressure than the surrounding water. This causes dissolved gases to precipitate out, forming bubbles. At least, I know that's the reason it's important to ream copper pipes when you're running water likes. The chlorine in the water, which is dissolved and harmless to the copper piping, will precipitate out when it passes over a rough spot, and the chlorine gas will eat the copper.

ROWINGADUBAY Posted January 14, 2010 Report Share Posted January 14, 2010 Is this lure mimicking the farting action of a dying baitfish!!!!!! Quote Link to comment Share on other sites More sharing options...

Dave Dave I think this was the post you thing of My link. I had some success with it and alot of failures also. Sorry the baits pics were deleted in this thread by mistake. I will try to dig this bait up( gave up after awhile). I think the topic was venting baits. Quote Link to comment Share on other sites More sharing options...

Thanks Mark, That makes sense to me now. I just couldn't figure that out because I guess I just didn't realize that moving water would do that in an enclosed or completely submerged object.

I just couldn't figure that out because I guess I just didn't realize that moving water would do that in an enclosed or completely submerged object. I think that's why bass busting shad underwater generate bubbles. Their tails whip through the shad, causing low pressure on the back side of the tail, and bubbles. Dave, A.K.A. Vodkaman, would probably know a lot more about this. Something to do with vortices. Quote Link to comment Share on other sites More sharing options...
