It is one of those strange things that has been around for all time. We have all experienced it at some time. Everyone who has ever picked up a table tennis paddle has seen the effect when they toss the paddle up in the air, watched it flip over and then caught it again. So well was the movement known that science forgot to look at it and come up with an explanation. Dave

This is an interesting topic. Going through Helicopter flight training this same motion was well discussed. Only to achieve the opposite results "Autorotation" . The forces of this theorem is to have the center of gravity move in a controlled manner similar to a navigational gyro. This could be very costly. Physics is the plane of finding how to control the action, in a constant manner. Good luck. By there were a few helicopter pilots, that have come very close to this. But the successful ones didn't survive, either the extraneous forces, or the violent impact.

Travis - my hard-bait molds should fare better being a cold process with a little exothermic reaction. It will be interesting to see if my suggestions can extract more pours directly from a 3D printed mold, it is just a prototyping method, and may produce enough for own use only applications. I do agree that printing a positive and molding in POP or other material would be the way to go, as I posted in my first reply. Dave

M and f should be a dead on match. Watermelon green that is. depending on what glitter is used is how the color changes. My watermelon blue flake is a dead on match as well as watermelon red flake.the blue flake makes it greener and the red flake makes it more brown. I read somewhere m and f is what GY uses. My green pumpkin is close as well. With all that said don’t get to hung up on a dead on match. You’ll go crazy. Lol. close works.

I haven't tried printing a mold as simply takes too long for something that I know isn't going to work as needed. PLA molds for soft plastics simply is a poor media. Much better off just printing the bait and molding it in both time, effort, and use of product. Maybe I will goof around over winter break with printing some masters and see about making a mold of them. I am so proficient in Fusion 360 might be done next winter.

Good reply Anglinarcher. My prey are bawal, a deep bodied very aggressive fish, which explains why I only need a belly hook. Dave

Mark - Yes, basically what I want them to do; between plywood backing plates, but with a lot more clamping. I didn't mention plywood thickness, I would say at least 0.5" or thicker. The problem with a 3D print the size of a mold is that it can take 24 hours to print, and so the overall mold thickness tends to get compromised. BUT, the mold is going to warp what ever thickness that you make it except it is going to require more effort to correct an overly thick mold, and it will take more intermediate bolt clamps to correct an overly thin mold. As always, design is a compromise. Just a thought - If we ever get the PLA molds to work, we could consider internal cooling pipe matrix for an air flow or possibly a water flow, but we should solve the immediate problems first. Here is an ISO view of my hard-bait mold half. Dave

You can make your own hanging filtration by using a box fan. make a box to hold the fan and filters in front and back. also a shop vac, with a cyclone hood on a 5 gallon bucket. you can Google everything you need, or YouTube.

@Rbertalotto A lot of predatory fish strike at the head of the bait. You can get away with a single tail hook on little stuff, but I've missed fish even on little lures with no belly hook. Additionally, the belly hook can provide a source of ballast to help keep the lure floating upright. My thoughts at least.

In past I had similar troubles trying to copy, with a 2 parts room temperature silicone, some chinese soft baits, instead I did not find any kind of troubles copying right "good" plastisol softbaits, so I think that such kind of marks depend by the raw material of soft baits that you will like to copy (especially the surface painted ones).

I agree completly with Fatman. I have had that problem before and it is usually because of too much talc in the molds. it also happend with some very old powder paint. the vinagar did fix the problem for me. I mixed he vinagar with half water, heated the water to 180F and then rinsed in clear water.

I am retired now, but unfortunately I spent my money on wine, women and squandered the rest. I once approached a large lure business with my ideas but did not even receive a reply, their loss not mine. I have worked hours as a contractor that would make your toes curl, but was paid well. Unfortunately my investment in my local beer establishment did not pay off. I have designs, but no money to develop. Investors welcome Dave

If I (or anyone) could make a perpetual motion machine I could buy every lure company in the world to design and make lures for me.

Yes i remember don I sit next to him every weekend at the monticello flea market he is a good friend of mine he still makes his lures at age 72 if you ever wanted to know fishing this is the man to talk too he knows alot his lures still catch fish salt water and fresh montcello raceway rt 17 b monticello ny you can find him 9am to 5 pm sam
