I'm kicking myself. I didn't go past page 5 on the search string. The answer was on page 6!! AAAAARRHHHH!!!!

Yes, I got one earlier on, no one noticed because I had hardly pressed the go button and KC posted the answer! What is the point of easy, Bring it on.

I'm beaten, I know the name is right but can't find anything else. I'm up for another from KC if everyone else is done.

It is sad and too bad. He may have gone home, but we still have the ball. I think that you were right to raise the issue Mike and I thought that you did it nicely, not in a disrespectful way.

Has anyone had eny experience using Gelflex for making moulds? It is a re-meltable plastic available in two hardness's. It is soft enough for undercuts and good for a couple of hundred castings off simple mould shapes. I would appreciate any feedback.

This problem occured a while back. I thought the best idea that came from that post was to try and contact the original pourer and ask him. Because he is no longer in business, he probably won't have any objections to sharing his recipe. Has to be worth a try.

What causes a tight or wide action.? This question was posed to me by Skeeter Jones. I thought it was such a good question that, although it has been mentioned a few times, it has never really been aired here on TU. The following is MY take on the subject and I invite you all to add your own thoughts and arguments. Several variables control the amplitude or width of the action or side movement of the lure. These are lip width, velocity, material density, lip edge shape (knife or rounded), body shape at the interface with the lip, depth of the body, ballast distribution, lip material, hardware, water temperature and what you had for breakfast. I guess I got carried away there, but to different degrees, they all have an effect. I will deal with them one at a time. Lip width. The frequency or how many waggles per second that the lure performs is directly proportional to the width of the lip and the velocity that the lure is pulled through the water. It can actually be simply calculated. Look up Strouhal, Wikipedia covers it quite nicely. If the frequency is low or slow, the body has more time to swing from one side to the other and therefore will swing further or have more amplitude. If the width of the lip is halved, the frequency doubles and with half the time available for side travel, the amplitude reduces. So, keeping everything else constant, a narrow lip gives a tighter waggle. Velocity. Covered mostly under lip width, if the speed doubles, the frequency doubles and the amplitude is reduced. At high speed trolling, the frequency could be 40

Dramone, PM sent.

I googled the orthopolywotsit. I could not find any strength figures. It stated that after curing, it has to be heated in an oven for six hours in order to reach full strength. If you can get a sample to try out, it has to be worth a trial. You then need to figure out a way of comparing with the other lip materials, or am I getting too involved again. All those members with shares in Lexan will want proof that it is at least as good.

You obviously will have a separate drill template for accurately drilling the holes in the lip blanks.

I saw the post originally, I sent you a PM. How about double sided tape. I think the silicone rubber is about the best idea though.

Hazmail, nice solution.

The mixing bondo with the resin sounds like a great solution. I suggest that you go ahead, lead the way and report back. With the fluidity and release properties of resin and non-shrink properties of bondo, I really think that you are on to something.

Regarding the resilience or ‘rock bouncing’ properties of the different lip materials. The idea that some materials rock bounce better than others has been discussed many times over the years. A simple experiment can be set up to test the resilience of various lip materials and put this one to bed. Cut a round disk of each material to be tested, say 2 inch dia. Drop it from a set height onto a hard surface, stone floor tiles work well. Measure how high the disk bounces. Repeat many times to get a good average. It would be a good idea to record the thickness that you tested also. The one that bounces the highest wins the resilience contest. I cannot do the test for you as I have neither of the materials in question. I’m hoping one of you out there will do the quick test for us all and solve the mystery and remove the suspense.

Q1. How in the world does a trailing edge cut through the water? Q2. How does this trailing edge create a vortex? Q3. How this trailing edge creates a stronger pull down force? Skeeter. I get the distinct impression that you are not buying into the application of vortex theory on the action of the lipped lure. But that is acceptable as I have never really explained the theory in words, I have only provided links to web articles on the subject as they explain it better and there is less chance of me attaching my own interpretations which may or may not be correct. This thread is not the place to deal with the subject comprehensibly, so I will limit the discussion to addressing your questions. Q1 and Q3 are essentially the same, my statement of ‘cut through the water’ was a bad choice of words. However, a lip with sharp edges front AND sides will exert more down force than a lip with just the leading edge sharpened. Explanation. Consider the requirement to move a body one inch wide through the water with the least effort. Like a wing, bullet, rocket or a submarine, the shape that you would select would be a torpedo type shape. The water (or air) parts at the front, slips by the object one inch wide and re-joins at the rear, causing a minimum of turbulence. Turbulence is a chaotic mess of vortices also known as drag. As the body is shortened in length, the effort required to move the body through the fluid increases. The fluid finds it more difficult to cleanly re-connect at the rear, due to the severity of the change of direction. As the object shape is shortened further to a sphere, the chaotic vortices increase further. As the shape flattens further and approaches a flat plate, the point at which the vortices are formed is at a single line around the edge of the plate. At this point, the force required to move the object is at a maximum and under the right conditions of speed, fluid density and size of plate, which are all present in the fishing lure application, the vortices join and act as one. Throughout the changing shape, from torpedo to flat plate, the area presented to the fluid is the same, i.e. one inch. The only difference is the trailing vortices. The vortices or eddies are low pressure swirls of fluid formed behind the edge of the plate or lip. They apply an additional negative force on the rear/edge of the lip. One could form an argument that the only force on the lip is due to vortices sucking the lip back and the supposed pressure on the front is less significant, but I am not confident enough to make such a sweeping statement that is so difficult to visualize and therefore be accepted. So, in answer to Q1 and Q3, if the lip edge was sharpened, the negative (sucking) force on the rear face of the lip would increase, thus applying more down force to the lip. As for Q2, as the water flows past the edge of the flat plate, it tries to fill the vacuum or void behind the lip. This change in direction causes the vortex to form. An example. On the next windy day, stand with your back to the lee (down wind) wall, right in the corner. Notice how calm the air is. You are now standing in the void or low pressure area. Now move slightly away from the corner. The wind increases, but the direction of the wind is toward the corner. The wind is rotating, a vortex is present. Throw some leaves into the wind and observe the movement of the wind. If a lure is already built on the edge of instability, then the maximum depth condition is already present. Any sharpening of the lip under these conditions will merely push the lure balance over the edge and the lip will spiral or death roll. However, if the lip is not on the edge and it is required to gain more depth, there are several solutions available. A. - move the tow eye rearwards. B – increase the area of the lip. C – shorten the body at the rear. These are all very invasive changes. Simply sharpening a thick lip to an edge will achieve the same result. It will increase the down force at the front and ‘cut’ more water.

The compound removes any grime attached to the bearings and any corrosion that is present. Unless you re-apply the compound many times, the steel bearing surface will not be affected. Like using emery paper, the compound wears out fairly quickly.

That was DEVIOUS!!! I stopped looking for Juha's, you naughty boy.

Post another.

All the hurdy gurdy is hurting my head. It's very dificult to pull the names out of the Finnish text.

Pete, that was impressive. The lip looks right.

It is very similar to the Sabatier effect in photography. I won't describe it here, too heavy. It is a way of producing a thin line of white between two black bodies. The result looks like a negative line drawing. Impressive, but hardly worth the six hours it took me to produce. What I think he is saying, is that lacquer applied onto wet lacquer, will run upto the previous coat, but not quite reaching it, leaving a rim of white. A good application for painting the eyes, with a very thin white rim. The fish will be well impressed and will select your piece of plastic over the real thing, any day!

I think the guy has way too much wanga to waste.

Palmetto Balsa, you cannot give it away. You have to post another.
