Lol, You obviously know nothing about compound bows. Not even medieval longbows were that high of a draw weight.

Yeah, it's that important.

Indeed, but some English longbows would reach 100-185lb, however the archers were trained from birth and the style of shooting was very rapid to minimise fatigue. There's no way that weight could be physically shot on a modern recurve bow, the shot cycle would simply make it too hard.

Edit: Goatz, if it hit your hand, then you're probably a tad impaired mentally.

no when you fire if you dont wear a leather glove at full draw, sometimes it just pulls a tiny bit of skin off your hand where your thumb is.

That's more related to technique than the bow. I've never been bitten by my 50lb, and I had shitty technique for quite a while. Just keep your arm slightly bent outwards.

If you can't draw the bow with your arm like that, then the bow's too heavy for you.

Zeus, he means on his release hand

1. Use a mechanical release
2. Use a mechanical release
3. If it hits your thumb, then you have the worst release on the planet. Your thumb shouldn't even come close to the string.

@Zeus, angling your knuckles at about 45 degrees on the grip will naturally rotate the elbow out of the way :wink:

sorry to bring back this old thread i forgot about it :oops:

anyway i have multiple fiberglass rods in my basement and garage. However they arent too thick there about the width of a bic pen. i was wondering if i were to somehow quadruple them up would that work? i need something fun to do because my project is on a stand still due to slow shipping :(.
How would i go along using wood? i assumed it would snap with what i had in mind.

You can bind four of them together as you described. If you want a bow with longer arms(say, three feet total width), two or three may be sufficient. Just start out with two and add them as needed.

Thinking of using wood? Ha. You're in for frustration.
Crossbows have to store a lot of energy in very little material, and most woods don't like being deformed to such a degree. You could back a thin oak board with some fiberglass (not difficult), but otherwise expect a lot of wooden shrapnel flying.

Longer wooded bows are not difficult, but takes patience and quite a thorough understanding of how wood behaves if you want a bow which doesn't suck.

And I'm not saying there's anything wrong with using a simple bent stick for starters, but don't expect much. Those bamboo garden stakes work well when bundled together. Avoid using pine.
