  1. CAD and 3D printing

    A LOT of time is involved. BUT, if you construct the model right, it will be possible to make changes very quickly and easily. Also, I can change the length of the lure, keeping the relative proportions. All the major dimensions are stored as variables, so simply by changing the variable value, I can control the model dimensions. A short stubby 2.5" lure will be no good as a 6" lure, but by changing the thickness variable I can make it useful again in seconds. Dave
  2. CAD and 3D printing

    Here is an image of my bluegill. I have this printed off, but I can't find it after my last house move unfortunately. Dave
  3. Archimedes Dunk Test

    I worked on the water displacement method before developing the 'dunk test', which incidentally I discovered here on TU, in an old thread. I rigged up jars with connecting pipes but no matter how hard I tried, I just could not achieve the accuracy that I required for small lures. The method works well for large objects as the error becomes less significant with size. I now own a gram scale that has an accuracy of 0.01g. With my old 0.1g scale I could get very close to suspension, but the new scale will nail it every time. Suspension is a lot more complex than an accurate scale though. You have to take into account the paint and top coat, hooks and eyes. The 'dunk test' can only put you in the right ball park, the rest is up to you. Dave
  4. 3D Printed molds

    I have had a 'taker ' for my offer. But unfortunately my work situation has changed, and paid contract work has to take precedence. My customer understands the situation, and I fully intend to fulfill my offer, and the shrimp will be delivered, but timescales are out of my hands. Regretfully, I have to withdraw the offer for anyone thinking of taking me up in the near future, but I may well open the offer again. I find this work interesting and challenging, even comparing with my normal work as a car designer. Dave
  5. How to shoot good tackle making videos

    I agree with the message, but this vid didn't cover the subject. I expected more - sorry! Dave
  6. New Swimbait Making Project

    Great video, very informative. Nice action on the swim test too. Dave
  7. Swimbait designing/evolution

    People are always accusing me of over-thinking ideas. But I am an engineer, that is what we do! Dave
  8. 3D Printed molds

    That is an amazing offer. I hope someone takes you up on this opportunity. Good attitude I will chip in with some free CAD design work if anyone needs it, to support the above offer. DAve
  9. Full moon fishing

    Very nice video, enjoyed it a lot. I wonder what effect the solar eclipse has on fish. My guess is that the fish will go into a feeding frenzy, as they think they have missed supper. Dawn and dusk are catching times in my experience. Dave
  10. hello from the new guy

    I have just moved into a new place. I had plans to set-up shop again. I solved the ventilation problem, as my new shop would be out-doors, under the cover of an awning roof. Unfortunately, I have rediscovered my love of fishing, and do two competitions every day. They will not allow me to use lures, which was rather distressing, but it is still fun beating the locals. On average I win a prize 2 out of 3 days. Dave
  11. 3D Printed molds

    I design my molds with the injector built-in. For the first pour, I block off the exit of the injector cavity, and then fill the injector. This gives me my injector piston. Probably not a good idea for hot plastic, but I only pour resins, for which this method works perfectly. Dave
  12. 3D Printed molds

    I also use No3 for two part molds. I also design my mold master so that the two halves are identical, this way I only need one 3D printed master. Also, because all the silicone halves are identical, I don't need to match them as they are all the same. Dave
  13. Weight in a crankbait

    I totally agree with Rosko2 - eye position is probably the most powerful adjustment that you can make. This is a good one to experiment with and learn. Eye position is key to attaining depth. DAve
  14. Weight in a crankbait

    The only thing that I can add to the marvelous and knowledgeable comments above; is when you modify your bait to improve, change only one thing at a time and make a note of its effect. If you change more than one thing, you learn absolutely nothing because you do not know the effect that each individual modification had. Yes, it is a lot of work, but with each change, you EARN knowledge that will reap short-cuts in the future. An experienced designer/builder has a 'feel' for what needs to be done. This comes from the knowledge of what each adjustment will do. That is why I say 'Earn'. Pay now with the work and effort, earn the knowledge, and apply it freely in the future. Dave
  15. Lure Drying RPM

    Ha! - Probably a lot. They wouldn't notice, except for the desire to 'burp' at the top (swim-bladder expansion) Dave
