@mark poulson - I too use alcohol in a spray bottle. I distill my own Dave

Pete - I put myself in isolation around mid January, as 5M Chinese visit Indonesia every year, so an infection was inevitable. The government numbers I suspect are nonsense, they are trying to protect the economy. They don't tell us where the infections are. There is no mandatory isolation, just weak advisories which everyone ignores. In recent weeks people seem to be taking it more seriously which probably means there are infections here in Bandung. I simply don't know the true numbers. I just did a fresh search for Bandung - 1 case, 0 deaths. What a joke with a population of 2.58M! Dave

Dgagner - not even close. Dave

Lure design is a lot about volume and mass. I did not say ALL because many of you believe that aesthetics play an important part. Personally I am not a believer. Mass or weight is an easy assessment; I own a 500gm scale that measures to two decimal digits of accuracy, equivalent to 0.00035oz, as good as it gets. Measurement of volume is a little more technical. You can multiply X,Y & Z to get an accurate volume of a block of wood, but that does not help with a complex shaped lure. You can use a displacement method (which I extensively experimented with) by weighing the displaced water by immersing a lure in a full container. But way too inaccurate for what we need for lure design. With a gram scale with an accuracy of 0.01g, or even 0.1g, you can predict volume to the same accuracy. Plus, you do not need any additional equipment other than an accurate gram scale. All you need is Archimede’s principal. Once you have accurate numbers for weight and volume, you no longer need float testing. The units of density are g/cm³. In other words, divide the weight by the volume in metric and the result is density. Fresh water has a density of 1.000, Sea water 1.025. Assemble a complete lure, apply Archimedes, and it will tell you how much ballast to apply. Dave

Dgagner - great post. To be totally honest, I did not understand this shit in school or college. I only figured it out when I started this lure journey. I can only put this down to the fact that my teachers had no practical application of the Archimede's theorem and so could not explain in practical terms. But, we have a practical explanation here. A chance to really understand heavy science. Archimede's was a lure designer Dave

Ravenlures - Sent. Dave

It is probably a misunderstanding of language. You are talking about a lure making shop, a shop that makes lures. I doubt if such a shop exists, though you might find a contact who could make lures for you. Tackleunderground, being a lure making website, I am sure we could help you to make your own lure at minimal cost. Dave

Lure MAKING is not a low price commodity, it is labour intensive and time is money. Personally, I charge $50 per hour, my main job I charge $100 per hour. I advise you buy some tools and start MAKING your own! Dave

AZ - Always sad to read of a member passing. Thanks for reporting. Big Epp - the S-motion is interesting. I wrote about this several months ago. A lure will waggle at a specific frequency given its shape geometry. But, there is also a pendulum effect. If the pendulum frequency matches the waggle frequency then the waggle will be exaggerated, and could be the cause of the bait going on its side. The lower the ballast weight then the slower the pendulum effect. Normally the pendulum effect has little influence on the waggle motion as the two are out of sync. However, if the pendulum is slow enough to match the waggle at a lower harmonic, then the two forces will combine and give an action 1/3rd of the normal waggle speed. Consider the waggle with capital letters representing combined motion. L r l R l r L r l R l r Superimpose the pendulum. L - - R - - L - - R - -. I hope this makes sense. It is a new lure movement concept that has never been explained before, and rarely seen if you don't experiment with shapes and ballast locations. Dave

I think Mark Poulson nailed it. The CoG is too centered which will cause the lure to tumble in flight. The same problem is encountered on hardbaits with fixed weight locations and shallow swimming lips that mess with the airflow (the equivalent of the spoon). The CoG needs to be as much to the rear on the lure as possible (leading the flight). Make the tungsten weight the last item, add a couple of beads at the front. Consider darts; the resistance to flight (the spoon) is at the trailing edge, the mass (tungsten) is at the front, in flight. The spoon, like the feathers of an arrow, tries to hold back the flight, the weight tries to advance the flight. Take a dart and throw it feathers first and see what happens. Mark is probably the smartest guy on this site. You should all listen to what he says (sorry Mark, but it is true)! Dave

Young's modulus is a measure of elasticity, generally expressed as a graph that demonstrates the springiness and yeald point in a material. If you take a piece of spring steel, you can bend it, and it will return to the same position. Bend it a little more and you get the same result. But, bend it beyond the yeald point and the material takes a set, it is permanently deformed. If you perform the same exercise with SST, it will take a set with minimum force. The Young's modulus of SST is way too low for applications that require maintenance of form such as wire spinner baits. Of course, design is always a compromise. One must weigh up the corrosiveness of spring materials with the long life of stainless materials. Try to make a twist eye from spring steal and you will be there all day, and hurt your fingers. But, SS is like butter in comparison. Young's modulus is the technical expression of what we all know. I sucked you in didn't I Dave

It is a Young's modulus thing Dave

Hiro - Your English looks fine to me, and it is good to see your name again. Interesting idea. I am sure there is something there from this effect. Dave

D2T because of its consistency has to be applied thick. I am guessing that you may have made the coating too thick. Dave

I was shocked when I first read this post, I imagined.... well, it is too scary to even write down. But of course, that is not the case, you are performing a round over operation. You are trying to do a complete round-over, and that never works in practice. I suggest that you increase the blank thickness by just 1/16", this will guarantee a good contact with the bearing. A minute or two with a piece of emery will complete the round-over that you are looking for. I use a flap-wheel in a drill press for this tidy-up operation. Dave

Yeah, you probably right, it would be a pointless exercise as I don't do pretty Dave

I would definitely enter, if I ever get this triple point lure built. Dave

How many joined TU because of last year's competition? Make your voices known now, and we will celebrate the competition. More than ten replies and I will be convinced. Dave

We need more posts/comments to encourage guys and girls to stick around. It is in our interest as well as theirs. TU is the premiere lure building site IMO. It can be imposing at first. But we all have a common interest, a common goal; we just want to build better fishbait, better lures. Simples Dave

I have mixed feelings about this annual competition. I see the value of all-comers, so we can see innovation and new ideas. But I am not seeing innovation or new ideas, just same old. I would like to see the competition limited to members only, and with a limit of time served, say 3 months or ten posts. It would severely limit the number of entries, but I am for the site, and these outsiders are not contributing, just trying to take. I would be tempted to make member viewing only, but that would limit the prospect for new members. BUT! I have to constantly remind myself once a year, that TU is not an exclusive club. If it was, how would I have ever have qualified with no knowledge or experience, to become a member of this club. I say to all none members reading this, who have ever taken a knife to wood, sign up and contribute. As I discovered, you do not have to be an expert to contribute. Put forward an idea, get shot down, have that idea improved, generate another idea from the original, and such is progress. I am a living testament to this process. Winning a competition is small-fry, actually contributing to your fellow designers and builders is the real buzz. Dave

@Hillbilly voodoo- they rarely do. I hate this time of year. If there was an entry class for CAD lure proposals, I would enjoy it more :) Dave

@eastman03 - Ha! They won't if previous contests are anything to go by Dave

Yes, I still do the washing hands thing. The alcohol spray is extra, just like using sanitizer. I am going to arrange a meeting with the village chiefs and elders to get some rules written down for when things kick off here. At the moment it is just business as usual, kids playing outside, people chatting in groups, Mosques busy as normal. You wouldn't think there was a global pandemic going on. They will find out the hard way in three weeks time! Dave

According to official numbers, Indonesia is only just getting started with around 700 cases nationwide in a population of 640M. However, I am not buying in to those numbers, I would say x10 or even x20, but no one is talking. I started taking precautions 3 weeks ago when it became obvious that the government were lying. I am using my stash of 75%ABV (150% proof) vodka in a spray bottle for hands and purchases. I hope this is enough. The biggest problem here is that a lock-down is not possible as most citizens live from day to day. If there is a lock-down, they lose their income and there are no social benefits. India has locked down, but the government has announced that they are going to support the poor. Indonesia better get their act together quick or we are in for a disaster that will make China and USA look like villages! Tough time y'all, stay safe. Dave
