Heck I have fired over 200 bolts with this string and the nylon cover over the centre of the string is just starting to crack, I think we need to try a few layers of heat shrink tubing like archers use. ? What do you think ?

You could always buy some Eastman flight rail lube which you run up and down the runners either side of the rail to reduce friction on the string. Or, you could do what I did for a wihle and simply use a little tin of releasing oil! I've seen some survivalist sites which say that butter or lard work just as well in a SHTF situation.

Thanks for the tip, currently I use Bohning Archery Tex-tite bowstring wax, its pretty darn good.

I like your thinking NR, I'll do the same, me dad (GRHS) had loads of shrink wrap in the garage, i think this will do the trick.

Shrink wrap tubing appears to be normal fitment on Barnett strings, but not on the other make, fitting it perhaps two layers thicj should reduce wear considerably.

hello there,

i saw this conversion done to the 80 lbs alluminum pistol crossbow.

www.youtube.com...

do you think we could disscuss and learn how to do the conversion ourselves here as a project?

i noticed there were a lot of good comments about bow strings and such, people here understand their crossbows.

it's a great little crossbow with ten bolt feeder magazine, great for compact spaces.

perhaps there would be enough idea and headfs to understand this conversion process. i am still looking for a feeder magazine design plans.

please could we put our heads together to understand this crossbow design conversion.

thanks.

good call but with the cobra 80lb pistol crossbow there seems to be a different issue. ive got 3 different pistol crossbows and have been using them heavily over the last year.ive found that with my spitfire 80lb that the string lasts for ages and only gets wear where its contacting the bolt but with the cobra the string is hitting the the pulling forks everytime its fired which is leading to instant wear.i have seen models of the cobra with the pulling forks further forward so there is no contact with the string but i think its a bit of a lottery unless you mod it.
