basspatrol Posted March 17, 2015 Report Share Posted March 17, 2015 I came across this lure awhile back. I made a master with sculpey , but I can't figure out how would i make the mold for this. Specially the tentacles. Any ideas? http://www.ebay.com/itm/321206109907 Quote Link to comment Share on other sites More sharing options...
MonteSS Posted March 17, 2015 Report Share Posted March 17, 2015 Buy Yamamoto skirts and bond them on. Quote Link to comment Share on other sites More sharing options...
basspatrol Posted March 17, 2015 Author Report Share Posted March 17, 2015 these have a conned shape on the tentacles. The action on the tentacles should be totally different... Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted March 18, 2015 Report Share Posted March 18, 2015 You could do it as two operations:1 - Pour the legs flat, in a star shape, with a central clamp bulb.2 - clamp the bulb in the bottom of the body mold and pour.Mold notes:A - The insert hole has to be just the tight enough to clamp the bulb, to prevent leakage when pouring.B - The body mold will have a dry cavity to accommodate the legs, allowing you to stand the mold up.C - The heat from the body pour would probably cause the legs to reset long. Even if it didn't, it would not matter.D - The legs will be a difficult pour. Certainly at least injection. I know vacuum forming would do the job.E - Might as well increase the number of legs while you are there.F - RTV would probably be best, but PoP would work too. I would go with PoP for experimenting, as these are both big molds.Dave Quote Link to comment Share on other sites More sharing options...
SlowFISH Posted March 18, 2015 Report Share Posted March 18, 2015 The only tricky part is the legs. I'd definitely mold the legs separate from the body... if you really wanted to, you could insert the legs into the body mold if you didn't want to glue/weld them together. As for the leg mold - a real quick/fast test would be taking a small cup and filling it with POP. I'd then wax up some toothpicks and insert them in very close to each other to mimic the legs in the pic (don't go too far as to trap them from being pulled out of the pop). Once it dries up - pull the toothpicks out and drill/grind/whatever a small area on top to give yourself some meat to the leg part - like a table top to you legs. The table top will let you pull the legs out of the mold and weld them to the body (I hope this makes sense). I'd then test with a real hot hand pour.... might have to heat the mold as well. Odds are, the legs won't vent when hand poured. So the next step would be to make top to the mold that allows you to inject. Look at some of the skirt mold out there - same principle except you have a very deep mold instead of very wide mold. I'd still make/test one in POP. On the mold I'd make sure the bottom/end of the legs close to the bottom surface of the mold (say 1/8"). Then get a real tiny drill bit and vent the bottom of the legs. There are some real tiny bits out there, you'll have to use a hand held pin vise to hold them. You should be able to make a vent that is small enough that the plastic won't fill/clog it. This mold I'd shoot cooler and wouldn't press to hard on it at all - to insure you don't fill the vents at the bottom of the legs. Hope that makes sense.

nedyarb Posted March 18, 2015 Report Share Posted March 18, 2015 I would buy the skirt mold from lurecraft. It makes skirts with about 20 tenticles, then cut 6-7tenticles off and fuse them together with a lighter Quote Link to comment Share on other sites More sharing options...
CNC Molds N Stuff Posted March 18, 2015 Report Share Posted March 18, 2015 If you wanted to just inject it as one operation you might be able to do it with a Mandrel like Bear's tube mold, or you might do something very similar with a 3 or 4 piece mold. It looks like the tentacles have a natural lie to the rear, so I do not think a regular skirt mold was used and fused on, but there are variations that might have been. .

basspatrol Posted March 25, 2015 Author Report Share Posted March 25, 2015 i just got a sample of the lures today. Very interesting how the legs were nothing close to laid flat as the tube molds. I think Bob was spot on on the 3 or 4 piece mold. And the tentacles did have a natural lie to the rear. . I am in love with this lure. I am going to try to use this vs the GY baby ika which is hard to beat. This lure was definitely injected (3~4 parts). Thanks guys .
