Title: increasing head weight
Post by: alex b on March 08, 2010, 07:11:00 PM
hi i have some 110 grain MA-2 broadheads and know i need a heavier weight. is there any way to increase the weight by about 30 grains?

things i was thinking-

-wrap wire around base of broadhead
-insert wire into center of arrow shaft
-those woodyweight things only problem is they are 40 grains to heavy ( i think ) or will a 180 grain head be good for a 40 lb bow with 35-40 arrows?
- maybe a small washer or metal tube on arrow
maybe even cutting a sliver off a field point?

will any of these ideas work? i would love some new ones too

thanks

Are they wood or carbons or aluminum arrows they have different weight tubes for carbon and alum.and wood you can use the woody weights or just buy a heavier head.for wood a new head might be better.

Yes there is a way.
If you give us the info lpcjon2 asked for then you'll get a load of answers to solve the problem.

o sorry for lack of info--

cedar arrows
35-40 spine
31 inches
40lb selfbow

the lightest they sell the woody weights are 70 grains that means i would get a 180 grain head...is that too much or is is good?

You need too drill a center hole, should be done prior too tapering the shaft, and you could use a finishing nail cut down too 30 grains, insert it the hole and glue the BH on.

Even if you like a long arrow 5" plus the length of the broadhead(probably 1") 6"is a lot in my opinion to have out front.You would have better performance and probably flight if you cut it down.2" inches out front would be ok.When you cut it down it will stiffen the shaft some,but As far as adding weight you can try the nail as jbuck9 suggested.I would just get new heads $30.00 would be worth the time your going to spend trying to fabricate something.

thanks for all the replies
since i dont have a grain scale does anyone have any details on the size the finishing nail has to be for 30 grains?

If you Google penny weight to grains you will get a calculator for that.

I typed it into the spine calculator.  You can use the woodyweights that are 40 grains too heavy if you cut your arrows to 29.25in instead of 31.  They would have the same dynamic spine as your current arrows.  Are your arrows tuned?  If they aren't, i'd cut them to 27in and add point weight until they tune.  Cutting your arrow down and adding point weight is good because the arrow will be slightly heavier but will have more foc.

You can add 30 grains to a glue on head with solder.  Just put 30 grains of solder in there and shove the soldering iron down to melt it.

I practice with the same weight that I intend to hunt with. Same shafts, same point weights.

BTW, I've increased my arrow weight by some grains, by adding fiberglass tape. Looks better than duct tape, but probably weighs a bit less.

It did not affect my arrow flight at all. Still perfect.
