I have done some tube dipping and saw an injection setup that didn't need to have the tails cut. I bought some stuff which came today. I heated up 5 oz of plastic and made some.

I got 15 3 1/2' tubes with a bit left over. There is definitely a learning curve here. This is a close up of one.

Nice. What does the mold look like?

GMAN · « **Reply #2 on:** January 28, 2010, 02:23:41 PM »

I really like that Jigman. How difficult is it? Is the head fairly thick?

I make all of my molds and learn how to use them as I develop them. I have been working on an injection tube mold for the last couple of years with no good results. I think these are the reel McCoy when I learn how to use them. The molds must absolutely be clamped together.

As of now I have $329 invested so that would be $21.93 per tube so far.

It will get better.

I bought 2 molds and that isn't half enough for some one trying to sell them. At least 6 molds would be needed ($480) plus all the other stuff.

This is the mold with the mandrel out.

This is the mold with the mandrel in.

I bought a double injector system. The nozzels on the molds are for single injection. The stuff at the bottom is for laminates. I may be there in a day or two but not yet.

That is cool. Is there a loaner program?

I'd like to get into that plus get me a grub mold.

Is that mandrel adjustable on the center pin so you could gain length of the tube body.

JackJ · « **Reply #6 on:** January 28, 2010, 05:41:28 PM »

Wow. Your machining those yourself?

Different mandrels can fit into it making different lengths.

I wish I were but I am mechanically challenged Jack. I have tried some stuff with bolts and fiberglass. I gave up. Then I saw these for sale.

Now that's all right!

The double barrel nozzle looks like it would be kinda tuff to make.

Those tubes look fine to me, JM!

Buzz the pic is misleading. The regular nozzles are removed and the pointy ones installed. The gizmo on the bottom is an adapter that goes into the mold so both nozzles fit at the same time. I haven't done any doubles yet but plan to today.

Those are really great looking tubes. I'm sure it will come out being cost effective in the long run. Are you making the setup to rig them on also? That is always my stumbling block. I have difficulty rigging them in a way that I like.

Good job!

Post up some pics

Jig Man · « **Reply #13 on:** January 29, 2010, 01:23:18 PM »

Here are the pics Gman. Pic 1 is the injectors with both types of nozzles and the adapter. Pic 2 is how the injectors fit into the adapter. You put the adapter into the mold, fill the injectors, then put the nozzles into the mold then inject both at the same time.

Steve how do you like to rig them: Tex, Texskin, outside weight, inside weight, jig head open hook, jig head weedless, ?

GMAN · « **Reply #15 on:** January 29, 2010, 01:49:21 PM »

Most of the time I texas rig it and skin hook the point.

Jigman, how complicated is that assembly to build? I am thinking if I buy the small attachements at the bottom of your pic I could build the rest. All it looks like is a basic piston design with an o- ring in it. Probably be real simple to make.

That's a good question. I don't really know the answer. I'm not trying to be pessimistic here cause I really do like fishing tubes. It's simple and subtle. I guess I get brainlocked trying to accept a rigging concept that gives good access to a wide bite hook without the plastic getting in the way. do you normally use a wide gap hook?

GMAN · « **Reply #17 on:** January 29, 2010, 02:20:13 PM »

GF, imo wide gap hook is a must for tubes. I miss way too many fish when I fish a standard hook and a tube.

Jig Man · « **Reply #18 on:** January 29, 2010, 02:26:07 PM »

I do not use a wide gap hook. The biggest problem I have is deep hook sets.

GETFISHED · « **Reply #19 on:** January 29, 2010, 02:35:05 PM »

Great pic. I like that open hook there. If I could just get more than one cast before I have to leave it at the bottom of the lake.

GETFISHED · « **Reply #20 on:** January 29, 2010, 02:40:38 PM »

Hey Jigman, on that there pic I have a couple questions. When you rig that tube on there is the weedguard the first part that goes up into the tube? Do you get to choose from different grades of plastic regarding softness and or durability ?

Tubes can be made from any plastic you want. I am using calhouns medium because of bear's recommendation. It is very soft.

Here is a pic of the process. Some lube is necessary (spit, WD40, spray silicone, or my fav. petroluem jelly with garlic powder mixed in) same stuff I put on my FnF jigs.

The tool thingy gizmo is a piece of TV rabbit ears with a roofing nail (head cut off) glued into it.

Gmam the tube is 0.924 ID 1.045 OD and 6 5/32" long. If you want the piston measurements and the rod length, I'll have to dismantle it. If I do, it will cost you.

thanks Jigman. Good enough for me. ;DI'll get to work
