? about weight tubes

[Sticks2117]

How do weight tubes affect arrow flight in carbons? Do I need them to get the arrow heavy enough to shoot safely? I want to try them but that's a lot of money to play with. I kinda want to cut my learning curve. I have some CX 150's and they are really light?

I tried them, but I could never get my arrows to fly well.  Now I just buy the heavier carbons like carbon express heritage and don't need them.  For me my arrows fly better without them.

Good luck.

I have used the lighter 3 gpi tubes,they did ok but the will nock out the nock if you hit something hard.Unless you glue them in,carry some extra nocks with you.I don't like to glue in push-in type nocks.I just went with heavier spine arrow and added more weight upfront to get a heavier arrow.The weight tubes were more trouble then they were worth to me.

I tried them, and I do not recommend them.

I use foam which is used for isolation under laminated floors. It comes in a big roll. It is thin but strong. because it is foam, it is very fexible and does not affect your shaft in any way, exept for the weight. I cut ribbons of it, as long as the shaft is. I cut them on the weight I want and weigh hem with a digital weighscale. To give you an idea: a width of 3/5 inch weighs around the 40 grains.It is very easy to make the weight you are looking for. I put a wire through the shaft, knot it to the ribbon and pull the ribbon with the wire trough the shaft. When it is on its place, I cut the wire. I spray the ribbon with teflon spray first, to make sure it goes in easy and doesn't stuck somewhere.
The foam material doesn't change your spine and is very cheap. After a few 100 shots it creeps a little bit forwards in the shaft; let's say 2 to 4 inches. It does not push your nocks out after the shot.

Hope this helps!

It works great for me and I am adding 30 to 45 grains in this way.

Personally, I love weight tubes.

I shoot just over seventy pounds of draw weight @ 29 1/2" of draw length. Getting carbon arrows to weigh up around 750 was difficult without adding some internal weight.

I usually use the mid weight tubes (can`t remember the weight per inch), and install them full length. I kink the tubes every two inches or so, and smear automotive silicone on the outside before inserting. Removeable if I want to, and they hold very well. I don`t have trouble with nocks coming out.

I have also filled the point end of the weight tube with silicone before inserting to put more weight forward. (If I needed more weight up front.)

It took some experimenting on my part, and it IS a pain waiting for the silicone to cure, but I like the results.
