Spend a day or so searching here: http://leatherwall.bowsite.com/TF/lw/THREADSx2.CFM Everything in the world of archery has been covered at this site for years. And, I mean everything! :thumb:
As far as using the dowels found at Lowe's for arrows, I'm not too sure you'll be happy with them. There's the matter of an arrow's "spine" and other such factors to consider.
All of this is covered at the Leatherwall.
While I dont suggest that anyone use a improvised arrow in a production made bow, but it can be done. Wooden dowels are a bad idea and the reason is that they catch fire very easily and never start out correct spine. And I found best way to get correct spine needed is to start with very green and flexiable canes. (Crape Myrtles and Bamboo work well) Roll them through flames of a fire never allowing them to singe or catch fire, this will remove water, take your time here as the spine will stiffen and you need to control this variable. arrowhead is another topic all together so is vains you need an arrow to spin in flight. any other questions feel free to ask
You'll waste time and money.
Just buy some good arrows that will last you a long time.
Unless you miss a lot?
You can get arrows that accept different points.
If you want cheap, get target arrows from Walmart.
Ramin wood.. The wood most dowel rod are made from.. Is (IMHO) only good for bows up to bout 30-35lbs.. Like those above me, I would suggest bamboo!I have made arrows out of dowel rods before.. For my sons PVC bow. 30lbs draw. They worked But wouldn't trust them for anything stronger.
I have found that young poplar is good for a quick and easy arrow. Now notice the word quick, it doesn't mean they are the best, it just means that they will do in a pinch if find yourself needing arrows. As for the heads, I use bits of thinner plate steel. The head doesn't have to be huge if your only hunting small/med-small game with it.
