Lexan Thickness For Balsa Crankbait?

Recommended Posts

If you want to try thinner bill material how about considering circuit board material.  Search here or internet for G-10 Material.  I found a model airplane site that shows how to make your own G-10 material.

Granger and McMasters also carry thinner material.  But this won't get you clear bills. There will be fiberglass cloth in it for strength in the circuit board material. 

 

If you want thinner lxan you could cut out a rough shape bill then sand down to thinner thickness.  Its more work and you'd probably want to get finer sandpaper to get the bill somewhat clear.  Also I remember a post where scratches could be removed by coating bill with a thin coat of resin.

I use 1/16" for everything, deep or shallow.  I also like the G-10 circuit board when I can find it in white color because you can go even thinner - 1/32" is fine for anything and it's stiffer than 1/16" polycarbonate.  What you choose is critical to the balance and performance of your crankbaits.  It usually takes multiple prototypes of a crankbait to get everything working right.  It's not important which thickness you begin with but I like to stick with whatever thickness I am using so I can control the performance of later versions of a crankbait.  If you change more than one thing in a series of prototypes, you can never be sure which change caused the difference.

i ordered some of the circuit board bills off of lure parts.com today with some eye lags or screws. all i have right now is a drawing made of this crankbait im going to make my dad has all the wood tools i need to get it done so it will all be an experiment when i start. I am just trying to get as much information as possible so when the build starts it can be half way smooth rather than a bunch of breaks trying to accomplish one bait. next ill have to research on sealing the bait or not before paint and how to finish the holes drilled for the eye wires.

As far as sealing goes it's my opinion that sealing is a necessity when building baits out of wood. Once the blank is shaped and sanded to it's final dimensions I add all the hardware. Line ties, hook hangers, ballast, etc. Then I seal with 30 minute epoxy. This insures the seal is tight around all the holes you've drilled into the lure. The bait is then placed on a lure turner until the epoxy is hard. The amount of time will vary according to the ambient temperature, but will usually be set up enough in about 45 minutes that you can stop the lure turner. This doesn't mean it's ready to paint. It still needs additional time for the epoxy to cure. I mix my epoxy in those little plastic medicine cups like the ones you get at the hospital. I leave the cup on my workbench and when the left over epoxy is hard enough that you can't leave a fingerprint in it when touched I feel comfortable that I can begin painting. After painting just top coat with the clear coat of your choice.

 

The reason we seal wooden lures is to prevent catastrophic failure as well as give us a smooth surface to paint on. If the top coat is compromised and the lure hasn't been sealed then the wood will swell and you've lost everything. A properly sealed lure on the other hand can be repaired. You may have to sand it down, repaint it and top coat it again, but you won't have lost the whole lure.

 

hope this helps,

Ben

We use 1/16" or 1.2 mm thick lexan or aliminiun for bibs here in Australia for small lures and up to 1/8" for or heavier lures for chasing Cod.Big lures always get bibs pinned in postition aswell as glueing.Easy place to find lexan is try your local hardware store and use the flat skylight sheets that you would put in your roof for your shed or patio.These are called polycarbonate sheeting same stuff as lexan.

I wrote an article on the comparison of various lip material's bending properties (July 2011) it involved a lot of research and some very heavy sums. I tried a search but I probably decided not to post it, as I know most of you don't like the techy stuff.

 

The results:

 

1/16" G10 was 3.5x better than 2mm polycarbonate.

 

I also came across another material that was twice as good as G10, called basalt carbon fibre. I don't know what its availability is, but it could be worth looking into.

 

I use 2mm polycarbonate, purely because it was readily available at the right price. I doubt I will be changing any time soon, judging at the amount that I still have left in my man cave. For small lures it is overkill, BobP's selection of 1/32" G10 would be a good choice for lures smaller than 3".
