Alright ive been reading about custom cranks being built with through wire construction.

now the newbie question of the day........whats through wire construction.

thru wire is a pain in the butt and the strongest way to build a crankbait.  

Take you blank and cut in half, now bend your wire to fourm the tail hanger, belly hanger and line tie.

place inside of bait halfs and glue back together.  That's it in a nutt shell, but there are more steps than that.  You have to accout for your balast weight and lip.  

I don't use this method, it adds a load of time to the build.  I've never had a hanger or line tie pull out of any baits that I've made (so far).

Here is an example

Thanks big I had heard of tournament fisherman getting their cranks built like that just so they dont have something break in a tournament. But never understood how it was done.

If the hardware is put in the bait properly the only way to get it back out is to destroy the bait.

I tested 1 of baits and the bait broke in half with the hardware still in place.    Thru wire is still stronger but there is not enough difference to offset the extra 1-2 hrs of build time.

are they more difficult to tune because of how they are built? If its not put in an exact way will it always run a certain way no matter how you tune it.

as long as the weight and hangers are centered then tuning should not be a problem.  You also need to make sure the lip is lined up perfectly also.
