Tube weight question

CAT22 · April 07, 2011, 09:50:00 PM

Anyone ever successfully mount a portion of tube weight (not full arrow length) into the front end of an arrow? If so, how? Would this have a negetive effect on arrow flight, such as not having all the FOC at the point? Would this change the spine if not full length? I think I have this figured out, but before I try I wanna get some insight.

Thanks, CAT

Just using a portion of the tube in the front half would be more trouble then its worth.Your not really adding that much weight.For me it is just easier using heavier inserts or points in tuning your arrows.You could try it and see,you would just need to glue it in place.But then you'll be stuck with it if it doesn't work out.I also like using the GT screw on weights behind the insert.

I would think it would be pretty simple to put some super glue on it and slide it into the front portion of the shaft. ive only shot arrows with complete tubes. it definately changes the flight but it was only for a 10 Yd shot worked just fine. I also use brass inserts and heavier tips and it works well.... however I also think theres a point of diminishing return where the Tail end of the arrow can get too stiff so youll have to play around with it. Good luck and post your data!

I'm asking this because I have some 10.5 gpi tubes. My arrows are 8.6 and I want to be around 500 for shooting 50 lbs. Full length tubes w my setup would be over 700. I,m not against that, but is there a point of diminishing returns on arrow weight?

I'll agree with JRY309 that you would be better off adding point wieght or using brass inserts. You would be placing your wieght further ahead which would give you better FOC than you would have by using wieght tubes. You may have to shorten your arrows or go to a shifter arrow if you add point wieght but you'll have to play with that. I've messed around a lot with wieght tubes in the past and was never really happy with them. I don't use them anymore.

If you do not want to go the heavy foc route, you could try some heavy weeder line or something else that you can go whole length with that doesnt weight so much.

I personally do not like the weight tubes. It was always easier for me to tune to heavier points. I got tired of gluing the nocks in so they wouldnt pop off.

Don't know what brand of arrows you are talking about, or if the inserts are already glued in; but, it would be easy to get around 500gr. by dropping gt brass weights down your shaft and screwing them in the rear of a std aluminum insert.

What are GT brass weights and where do you get them. Will they fit micro shafts? I want to weight up a few arrows for my lighter broadheads.

Gold Tip weights are steel and they are made to screw in the back of a Gold Tip insert.Those shafts are 5/16" outside.

Don't tell that to the brass 20 and 50 grain ones laying on my work bench next to the 10 grain aluminum ones..

PDP's are steel.. and require an adapter to fit the insert..
