Quite simple - It is the standard lathe turned part. But instead of cutting a plane, you cut a right-angle. for the corner radius, you drill a hole through first. Dave

Yes, an old thread. But I will add, that anyone worried about applying CA glue with the bare finger, it will wipe off easily with acetone, so no big deal. A cheap brush might work, but I would be nervous about the bristles sticking. Not a huge problem if you have a sharp blade ready. Dave

The lightest that I could get the resin with MB's was around SG 0.67 which is the equivalent of a heavy density wood. The thickness was that of mustard, so it could not be poured, but I did manage to inject the mix with a cake icing syringe. Dave

This is good. Dave

Here is another way to increase the wiggle. Dave

Consider a concave face to the lip rather than flat. Yes it is a lot more work, and difficult to get symmetrical, but it will generate more wiggle power. You need to experiment with tow eye position on first prototype. There are no formulae, all we can offer is best guesses for a testing start point. Dave

Angus - glad you are on top of the radius thing. As an engineer, this is basics, but no everyone has trained as an engineer, so it needed mentioning. Dave

The baits look great, and I can see a very nice 'S' action going on there. The problem with this style of bait, is that there is nothing driving the bait down the water column, compared to a lipped bait. The bait swims straight and the line pulls the bait up to the surface, as the line feels the resistance of the water. I have never tried to drive this kind of bait down, but if I did, the thing I would try would be to position the tow eye higher up the bait, onto the forehead. Nose heavy internal weighting, so the bait rests nose down, might grab you 12" of depth, but I have not tried this, as people generally want their baits to rest horizontal. Another alternative is a lead weight mounted a couple of feet in front of the bait, to drag it down. Trial and error to find the size of the weight, just enough to overcome the line resistance at the speed of your retrieval. Dave

We need some pictures to help you. Dave

Like Bass100, I suspect the tow eye position. Dave

If the lip becomes an issue by snapping off when bounced off rocks, the solution is to design in a radius between the body and the lip. This will act as a strain relief, spreading the loads out. Cracks and tears happen at sharp corners because all the strain concentrates at the corner. Remove the corner and the problem goes away. This is why aircraft have round shaped windows. DAve

I suggest that you start a new thread with your problem. Post a pic of the lure, and the solutions will come thick and fast. Welcome to TU Dave

X2 - stripers online do a lot of this kind of work. Don't forget to come back though Dave

Working with clay requires practice and skills, just like working with wood. Paul Adams on YouTube is well worth watching, and opens up some of the knowledge. I prefer wood, or depending on what I am making, various materials all combined. Making masters in wood is a lot more forgiving than you might think, because if you remove too much material, you can always add more back with fillers. Dave

As far as I know, the paid for MWB is no different to the free. I don't generally pay for something if I don't have to, but that is how impressed I was, it saved my computer. I have MWB on all the time, but it is not necessary to do that if you don't want to. It is not intended to replace virus software. If you have a specific virus problem, you should look it up on a clean computer if necessary, to find the way to clean the virus. This may well involve other software in addition to MWB. Some of these viruses write themselves deep into the core of your computer, and can re-embed themselves every time you remove them. It takes special procedures to get rid. DAve

This is a terrific project. My first thought was density issues, but if your material is 24% then that is not an issue. You are basically leading the way with a project like this, so I suggest that you get one finished and proceed to the water's edge. Don't forget to report back. Maybe a little video! DAve

I use FF and as long as I clear the history regular, everything on TU works just fine. I just cleared my history a couple of hours ago. TU just will not work around add blockers. Good job done by the software writers. Make sure you add TU to the exceptions list. Malwarebytes is excellent. It is free, but I liked it so much, I decided to pay for it. Dave

I know this issue is always at the front of Bob's mind. He has masses of knowledge and information to share, and often lets his business interests stop the flow, for fear of reactions like this. Unfortunately, this is likely to slow down the valuable input from Bob and we will all lose out. I suggest that if you think there is an issue, hit the report button and leave it up to the site moderators, that is what the button and the moderators are for, and that is what I do. Voicing opinions in the forums just causes bad feelings. Dave

Sorry it didn't work, but that's all I got Dave

I went for a boat ride in Phuket. The guy had 3x Mercury 250cc o/b motors strapped to the back - I think I would feel much safer in yours Dave

Dsotm - the link is fine as you have it, but if you want to hide the link in a word, you need to select 'more reply options'. If you did this and it still didn't work, you probably need to empty your history. The link was very helpful, thanks. Welcome to TU Dave

DiametricD - I wasn't going to say anything. BUT, you state that you are going to get involved, so I had no choice. Do a YouTube search for 'vortex shedding', and you will find vids that display the actions and forces at work to produce the 'waggle'. Dave

Mark - It is called a high density eurethane, capable of being machined and used for their impressive list of applications. The quoted density is 4Lb/cuft. This is extremely light. Consider that lure builders use a 16Lb/cuft foam to make lures, which is an equivalent of the very heaviest balsa or a very light wood. In metric, this would be 0.25gm/cm³ which is 25% of the density of water. So 4Lb/cuft would be 25% lighter again. Insulating foam-in-a-can, used for water pipes, is a foam with the same 4Lb/cuft density, but soft and can be squashed with finger pressure. They have come up with a material that is a lot tougher than this, BUT, nowhere in the article did they call it a foam! Is it usable for carving lures? - I would say yes. With that rigidity, it should carve, machine and sand well. Usual sanding safety dust precautions apply. Dave

This is ideal for spreadsheet. It is not difficult, but you still have to do it. AND it's free. Dave

Thanks for the response Frank. DAve
