I had some arrows laying around and decided to try a few different things. I footed the arrow shaft with a two inch piece of aluminum arrow. I then added a two inch screw to the back of the standard insert and ended up with 225 grains total with a 125 grain tip. I then used contact paper for an arrow wrap and fletched them with three five inch feathers. I then added a piece of rope for weight and ended up with a 600 grain arrow. All the things that I did were ideas I had read about on here and then I just used stuff I had laying around here. I have a few questions though. I did this with a light arrow (Vapor2000). Could I shoot this arrow out of my 55# longbow without damage? I have been shooting them and they fly really well but will they hold up if I was shooting them into something other than a foam target? Each carbon shaft is spined for a certain draw weight but can you exceed that without trouble? Thanks..Henry

Most bow builders want 8gpp and above. At 55# that would be 440grn , at 600 you are just shy of 11gpp (10.9), nothing wrong with that at all.

Thanks pops. Anybody have an opinion on my question about exceeding the reccomended draw weight on carbon?

You can go as heavy as you want.  It's the real light arrows that can cause damage too the bow.

How does your combo shoot?

It shoots real good. I just have a friend of mine who was saying that I would be taking them past there breaking point, so they would just break if they came in contact with bone or something hard when shot.

No problems exceeding the weight recommendation on it.  I think they are only on there for compound shooters to determine what shaft they need.  The spine is the only information that is useful to us.  I wish carbons came marked with the deflection instead of these other numbers (ie...150, 2000, etc...)

I agree mooseman, but it was in the back of my mind wondering if I was going to have trouble with these. Thanks for all your advice I can always count on everybody on here..

yep you should be fine if they are shooting good for you. I have some beman mfx .500 full length with 505 gr up front that shoot great out of my 55# longbow . Shoot what flies best and don't worry about it. Drew
