This keeps falling off and costs £20 a go
so i bought one of these for £17.

took off the roller and fitted it to to the Gamut boomarang. It has not fell off yet and works just the same.

Loctite is your friend 🙂

Have a look at the blackspire spares too.

I know I was stupid not to use it especially on the second one 😳

Will have a look..Thanks

i used a longer grub screw with an M3 lock nut on to hold the main roller bolt in place, i can post you what you need if you wish to go this route

Runs out to have a look. Grub Screw ?????

Edit Waddles out due to bad back 🙁

Mine has a tiny grub screw, I did not know it was there 😳

This explains why the second one did not last long !

Thanks for the info STW rules ( sometimes anyway)
