Their needs to be a flat between the nose and the tow eye. As I see it, with the rounded shape, a weak vortex is created at the start and sets the lure in motion to one side. BUT, when the next vortex on the other side is formed, it is too weak to change the direction to make the wiggle, and so the lure spirals. A flat, as described above will increase the vortex strength and allow the required change in direction. To test out this hypothesis, a thin plastic flat can be soft glued as described and the edges filled with soft modeling clay or even hot glue might work. Google 'lipless cranks' and note the nose flat. Dave

Pete, I fell for that one too. Still, good information. Dave

I was a member of a website dedicated to the Thien. I did a quick search but it seems to have disappeared. Still, plenty of articles are available for this simple and effective build. I liked it because it was based on vortices Dave

Consider plaster of paris for the mold. POP has a superior finish. Dave

Alsworms - sorry if I gave the wrong impression. I did try to word my post so that I was NOT attacking the moderators but merely acknowledging the problem and to offer my services. If you really feel that this post will make the situation worse, then just remove it. No problem here. Dave

It seems that TU is having a severe spam problem. Obviously all coming from the same person and possibly the same IP address. If you need a volunteer to help deal with the work load problem then I am at your service. Dave

I hope you do stick around, I look forward to reading new ideas. Basically, the gallery is for showing off your work with photos. The forums are for questions and instruction. Photos only permitted if they contribute to the subject under discussion. Dave

I have never heard of 'pipes' as a construction technique. Probably labeled different in the software that I use, CATIA V5. Dave

Every year I get majorly irritated by the contestants that don't read the simple rules. So, this year I decided NOT to read the rules to remind me of the infringements. The ploy has not worked, I am Pd off as much as I ever was. I have entered photography contests many times. The first thing I do is read through the rules at least three times to be sure of the requirements. What is wrong with these people! Dave

Don't throw out your failed silicone molds. Shread them or cut into small pieces and add to the mix for your next mold. This will save volume of fresh silicone. I believe the silicone sealer (vinegar type) will also serve the purpose for regular silicone, but perhaps someone could confirm. Dave

POP warning - do NOT pour any white milky remains down the kitchen sink. It WILL settle and harden. Dave

POP can be both, but in out application it is a mold making material. POP for casting resin is risky. If you die-lock your master, you will need a hammer to retrieve it. Dave

Plaster of Paris (POP) is certainly the cheapest method of casting, and the experience carries over to other materials later. Quality is very good too. But beware! If you are pouring a hard cast like resin then you run the risk of trapping your cast in the mold. This is called 'die locking'. You must be able to lift out the cast perpendicular to the split face of the mold. Dave

The bucket method is your only option unless you use CAD. You can calculate how much weight but not where to put it. Dave

Well, with your experience it might well be worth having a play with. Most software, even the expensive professional software, is available free using torrents, this is how I am able to use Catia V5 design software. Tell me the name of the software and I will see if it is available for you. Dave

Flow analysis software will not help. It is very basic, flow past an object. I looked into the idea years ago and quickly rejected the thought. The software is expensive and complex, requiring some knowledge of the fluid dynamics subject. Dave

I have read those articles too, only I was not able to source those ingredients locally. I wish you luck with your project. Dave

RiverSmallieGuy - That looks like the tank that I designed, except mine was 8'x4'. Basically a screwed together frame with plywood panels and angle supports to stop bowing and bursting. The simple tank is then lined with a sheet of polythene. For mobility when moving location, the framed panels are easily dismantled as they were all dry screwed. I made the tank in two halves that butt up to each other. It was a great tank, served me well. In the video below, see the first 15s. To the left of the tank you see cover panels. These prevent algae formation.

Fecetious, but a good point. Dave

I really don't understand why this video has been included, it has no relevance to your question. Do you work for the company or something! Dave
