Whychwood crimps slip then snap 25lb boom. (39 posts / 2,975 views)

Hi I have an issue using Whychwood crimping pliers and Whychwood 0.6 crimps.

When I test the 25lb boom between two pulling tools it always slips then snaps somewhere near the end of the crimp.

I'm placing the crimp the correct way in the pliers and ensuring even distance of crimp is sticking out of both ends to give the flared effect.

I then just squeeze as hard as I can. However every time I test it it snaps under maximum pressure.

I'm making small loops either end of the hooklink and blobing the ends ?

Anyone got any ideas what I'm doing wrong

Crimps dont make it indestructible. If you are pulling hard enough it will break. 25lb of pressure isnt a great deal for an adult.

Thanks but it always slips first then snaps at crimp, pretty sure I couldn't snap just boom material between my hands ?

Are the crimps breaking? Didnt korda change the material of their crimps to brass because of an issue with the boom and the original ones?

Can't really comment on the snapping or the crimps , doesn't sound right tho ....., but you'd never put anywhere near 25lb of pressure on the hook with a rod , hold a lead and get ya mate to bend into it , you'll be amazed how little pressure is there..

Im sure i read in the pst its about 4lb of pressure with a rod and line. T/c and line choice dependant obviously.

But 25lb between your hands isnt a lot at all, and youd easily be able to put that onto a short length of line

No The crimps are not breaking the boom does at one end or the other, it starts by slipping then snaps very close to the crimp.

Try with a crimp on one end and a standard loop on the other - that way you learn whether the crimp is better than a normal knot.

If the crimp gives before the loop then it needs attention.

Never had a crimp go with boom definitely user error unless your literally pulling for a break. Can't be crimping correctly.

So what am I doing wrong then ? Are you using Whychwood crimps and tool ?

Really can't understand it myself, as I say crimp is in correct way, even both sides , and squeezing hard ?

I've tied loops with a figure of eight knot at each end and it's far stronger, the boom appears to slip initially then snaps?

Grab your scales and see how much force you are pulling with. You will surprise yourself

Korda 6mm boom snap at 19lb (scale test) more than double you need to land a fish.

Put your crimped boom with one end at a scale and start pulling. Have a look at which force it snaps.

Do the same with 2 knots in the boom.
It will easy your mind if you see the force needed to break the boom section.
Are you sure?

This action cannot be undone.

Yes, continue
