    Default please help me with this simple invention

    Not to do with woodwork but Iím posting it here because there are more practical people here then anywhere else I know.

    What I want to make is a tube somewhere about 40 to 70 mm diameter and about 1000mm long, with many very thin diameter tubes inside. Imagine a 1 mtr piece of poly pipe packed full of drinking straws - that would be perfect except drinking straws are only 300mm long and I want them to go the full 1000mm length.

    How would I make this? Any ideas ? Obviously what I need is very long tubes with of thin internal diameter with very thin diameter walls.



    Expanding on this for those still interested. This is for fishing. Specifically for fishing for larger fish like kingfish and jewfish from the shore. It sits beside the rod which is in a rod holder and itís purpose is to allow the fish to pick up the bait and feel NO resistance until it has swum for a few (10 or 20, say) metres. At the end of those 10-20 metres the line goes taught and the fish comes up against the drag (which is pliers-tight), turning the circle hook in its mouth and embedding it.

    To finish the contraption off requires a spike at the bottom for pushing into the wharf or sand, and an adjustable clip at the top to prevent line spilling out inadvertently. line is pulled out of the rod and loaded into this contraption, which is the purpose of the very thin inside tubes, line is pushed into each one and they guarantee a tangle-free release (of that part Iím confident, as I use it on other rigs).

    For those not experienced with fishing for target species such as those mentioned, the issues needing to be overcome are that:
    1. Big fish are wary and hard to hook because they tend to spit the hook immediately they feel some resistance
    2. Big fish tend to swallow baits slowly, usually only taking it fully into their mouths after swimming off for a few meters.
    3. You donít strike circle hooks, you allow the line to tighten naturally, and the hook rotates in the fishes mouth and embeds itself in the corner of the mouth. This works better if you allow the hookup to occur before you pick up the rod.

    Any help appreciated
    Cheers

    I get what you're trying to achieve.

    Why don't you just use a handline after the rod? I reckon it'd be much simpler.

    Yeah, maybe.

    I expect youíre meaning a handcaster, one of these Jarvis Walker Handcasters - DINGA Online .

    Iíd like to try both and see which one works best.

    Iíve had a lot of experience designing similar solutions and my preconception is that the handcaster will have a tiny, residual tendency to go awry when things get panicky, plus I think it will be difficult to keep the line on the handcaster when wind, waves and dogs are thrown in the mix. I have used the thin tubes solution and it never failed to release the line clean and tangle free - though I was limited to conventional drinking straws and therefore only about 4 metres in total.

    I will keep rethinking both solutions. Build and test, build and test .... it never works like you think it should.

    If I understand correctly I don't see any huge problem piece of stainless pipe fled with smaller stainless pipe (6mm) will not be cheap, or you do the same thing with acrylic pipe and tube

    Hi,
    Check out the irrigation isle at the hardware shop, you may find something.

    Tubing on a roll? Straighten it with hot water?

    I would be worried about chaffing the braid as it is pushed into the tubes, you would want very smooth edges.

    Have you tried a baitrunner reel? I have a couple of Shimano Baitrunners and I think they are great reels. Even just fishing with an open bail should provide bugger all resistance.
    Those were the droids I was looking for.

    A couple of good points raised.

    Not stainless steel - too expensive and too heavy. Preferably lightweight, cheap, plastics.
    Yep, maybe I can find something on a roll in the hardware store, and maybe among the micro irrigation products.
    And the use of softer plastics prevents chaffing.

    Hereís an example of the same concept used for a different use. This was actually the core of a rather tricky device that goes inside a float. One loop of nylon is pushed up each drinking straw using a plunger. The straws simply prevent tangling by keeping the loops separate. A rubber band was all that was needed to prevent the nylon from spilling out inadvertently.

    Tomorrow if I get time Iíll be making a prototype solution using a handcaster and some type of home-made clip. It should be interesting.

    Cheers

    Yep, I do use baitrunners but I only have small models. love them. When I bought my last big reel I was tossing up between a conventional reel and a baitrunner and I stupidly opted for the conventional.

    They’re not ideal for this job though because you need to attend the rod to crank it into gear at just the right time. I want the fish hooked and pulling line against the drag before I touch the rod. I so often see people using circles and pulling hooks out of fish’s mouths because they are used to fishing j hooks and old habits come back when the thrill of a big fish takes hold. I do it myself too.

    Would a sheet of Corflute (as used in election campaigns) with a Stanley knife cut in every second core to allow the sheet to be rolled up into a cylinder work?. I would imagine it would look like a bunch of straws. You could try softening the sheet with hot water to make it roll up easier. I think I have seen Corflute at Bunnings in the building materials aisle. Screen printing or sign writing supplies would be a good place to source some material.
    I received some from a traditional printing place years ago for use as set panels in a school eisteddfod the kids were involved in. Yours truly ended up making the frames to attach the Corflute, and some very talented kids and Mums did the set painting.

    I'd look at getting the smallest poly tube that you can find, probably 12mm, pieces a metre long will give you 2m each, arrange them in a bundle, after deburring the ends, and glue together with Super Glue.
    If you wanted to keep them together to withstand abuse, get some marine ply offcuts and drill the holes in the required pattern and slide over the bundle.
    To load the tubes use a bit of sanded dowelling with a notch in the bottom.

    Googling "long drinking straws" immediately came up with a few possible results. One Aussie site had 70cm straws @ $3 per 50... (Ignoring postage, etc.)

    28" (71cm) seems to be lthe longest readily available, but I'm dead certain that when I went hunting for straws for a project I had some time ago I came across 1.5m lengths as well as a couple of sites that handled custom sizes...
    I may be weird, but I'm saving up to become eccentric.

    How about heat shrink ? It comes in numerous sizes and is soft and is available in those sort of lengths

    I think thatís the perfect solution. 700mm is near enough to 1000.

    Oddly, I googled Ďlong drinking strawsí too, but only came up with Overseas sellers. I guess I did something wrong.

    I also found out that party shops also have them, apparently for something to do with balloons.

    I can now set out to make a drinking straw and a handcaster solution - and see which one I prefer. Total cost $2.99 plus postage, as I have everything else.

    Anyway, perfect.

    Cheers and thanks
