I tried a search looking for info on straightening bent shafts but I couldn't find anything. Does anyone have any tips in this area. I had a grouper hole up under a ledge a few weeks ago and he did a number on a Riffe Euro shaft.:( It was that shafts first and last shot!...go figure. I think I will be buying a few of the RA shafts soon. Less than half the price!:hmm The other Riffe shaft has held up great though through numerous beatings by african pompano, cobia, grouper, etc...


Well, if nothing else the title of this thread should get some attention....I'm sure the peanut gallery will have some entertaining comments about my bent shaft. :D

Thanks,
Matt

hi

Matt be careful when trying to straighten it. I snapped one of my Ra spears not long ago trying to straighten it in a vice :duh

cheers
 
Matt, you can go to hardware store and get a small bottle of mapgas and tip for about $10.put shaft in vice and heat it up w/gas.Slowly push it straight w/pliers.after it is almost straight put on floor and roll it.You`ll see what needs to be straight and then repeat this.you can also walk on it while hot and push alot of it straight w/ you`r weight.in all it takes about 15 mins.:)
 
good luck trying to get the shaft straight. I doubt no matter how hard you try, you wont get it to shoot like before.

Personally, i wouldnt spend the money on a riffe euroshaft. I recommend the RA shafts because of their low price and soft steel. This allows the shaft to bend and return to its original shape without damage. Granted, if you bend it too far it will ruin but it will last longer than the Euroshaft. The euroshaft is made of high quality steel which is hard to bend but when it does, you will NOT get it straight.
 
I'm not sure about heating up a shaft. If that shaft has been heat tempered, you will effectively ruin that temper and severely weaken the shaft. We have done it the hard way by putting it in a vice then trying to bend it but like Ivan said, be careful about snapping the shaft.

Matt, if you want to try and straighten the shaft (and I would since you have nothing to lose) I would go the torch and vice route. Here is what I have done in the past with other metal things that I have bent into shape; get the shaft as hot as possible try and bend in back into shape while wearing some very heavy gloves. After getting it straight, heat it up again and cool it off with oil (I think motor oil will work) and you should have a shaft that is both straight and hard :D . Now I have never done this to a shaft and I don't know how the stainless steel is going to harden with the oil but I have done it to other things and it has worked. I have friends from Cuba that use to make their own knives for fishing and diving and they would harden the steel by cooling it off in oil. If you decide to try this be very careful and let me know how it works out for you.
