weight tubes

[Beanbag]

Got a question about setting up my Trad Lites. Shooting 30" with 175 up front out of 54# Moab. Arrows are pretty close to darts but are coming in just under 500 grs. Would like to get the weight up. Does putting tubes in change the spine/tuning? Thinking about 3gpi from 3 rivers, should add 30+ grs.Thanks Jim G

The weight tubes are design for parallel shafts,not for tapered shafts like AD's.I shoot some Trad Lites with 175 gr. points and they weigh right around 515 grs..You might try adding some rope,it will increase weight.But for me I don't like adding stuff inside my arrows.AD Trad Lite Hammerheads will be a heavier shaft.

They didn't affect the spine on my Beman Bowhunters.  Or at least not enough to tell, when you're as bad a shot as I am, its hard to tell when the equipments off.

LoL, Was wondering that myself!! Jim G

Weight tubes will not change the spine. One thing you want to do, is cut the tubes so they fit  the full length of the arrow with just a little room to put your nock back in place. Once you have the length cut, pull the tube back out and squeeze it with a pair of pliers about every two inches or so. This will keep the tube from popping the nocks off your arrows when they hit something hard.

They didn't affect the spine for me, but I couldn't keep the nocks on for the life of me.  Cut them with no slop.  Crimped with pliers every inch.  Tried every trick I read on this site.  Eventually tried gluing the nocks in.

I like stump and 3D.  So I hit hard stuff (wood that's not rotted enough) a lot.  And I was going through a lot of nocks.  So I gave up on the tubes.  Figure next time I'll spine up one notch and use heavier heads.

Just glue the nocks in.  Never understood why someone would want a nock with a chance of moving around on 'em, anyway.

I think weight tubes are gonna be a problem for you in a tapered shaft.  Going to be very difficult to get them to stay put.
