I have been using my european railgun now for about a year and have re-rigged it a few times. Recently I have lost 3 spears in nearly as many sessions (expensive)!. This has been due to the mono getting snagged in the articulated wishbone or the mono simply snapping at the point where it threads through the spear.

I am always careful to make sure that the mono is not twisted over the spear when loading.

I have tried 1.6 mm mono instead of the 1.4mm mono the gun was originally rigged with but this tended to snag. I tried Cressi 1.4 mm mono and it snapped (1st session). I have now bought some Leadertech 1.4mm mono and some anti-chaffing covers to thread over the mono at the point where it loops through the spear. I haven't been able to try it out yet as I am awaiting delivery of the new spear so I don't even know if the new rig will work (the loop may be too thick to fit in the spear/firing mechanism)?!

Does anybody else have similar problems and how do they overcome them? And also, can anybody recommend an inexpensive/reliable spear supplier in the UK.

Mono is terrible with abrasion resistance. Most likely you have some sharp edges around the line hole. You can try buffing it with a dremel and a buffing head mixed with some SS buffing compound. I have given up on steel wishbones and prefer to use spectra. You can get euro shafts now with tiny fins which work great. Otherwise you can use needle files and a dremel to fix up the wishbone slots. If your wishbones are still getting frayed it is a good idea to simply have loops in your bands which allow easy and very quick wishbone change. I use 1.9mm spectra for my wishbones and even on the shafts that have slits, I have no problems with it fraying, and I use a very thick 3/4" small cavity band.
 
Thanks for the advice Speareasy. I think i'll change the wishbone to a cord one. The rubbers are probably due for a change anyway so now would be a good time to change it over.
 
I use wishbone inserts that I tie Specta/Dyneema to.

Screw caps can also be use to like the OMER to tie Spectra to.

The Spectra should not be too thick so it will fit the shaft grooves or fins.

I use Spectra instead of mono for shooting line.
