A little crossbow help?
« on: January 09, 2012, 12:38:35 AM »
Buddy bought a crossbow.  No string, no brand that I can find. I'm the "gun guy" so I get the questions.

Unstrung it is 26" notch to notch.  What length string am I looking for?

Does that transfer to bolt length?

Strongly suggest he take it to a shop that deals in crossbows. The string and the bolts need to be matched to the bow  Those things can store a tremendous amount of energy and limb and stock failures generally fall in the catastrophic catagory.
I dabble in making primitive bows and  can make a flemish splice string and while I've never had a bow or string fail on me I've seen the results first hand.
"So, how did you lose your eye/teeth/nose?" are not questions you want to have to answer.
That it does not prominently display a brand would make me question it's quality.

Yeah. 

I get squirrely when the only labels are "Crossbow" and "Made in Taiwan".

http://www.mac.asn.au/string_making.htm

I researched string-making.

I wanted to make a longer string to reduce the weight on my 80 lb hand-crossbow (see below) with a one-piece aluminum bow.  It is too noisy for what I wanted (sounds like a screen door slamming) and is too hard to string.  (You can't use your legs to string it, like a regular bow.)  I figured an inch or so extra on the string would do the trick.  But what with the cost of a whole roll of Dacron or whatever you want to use, et cetera, just for a one-off string, I finally decided to just have the pros do it.  But I never got around to bringing it in for measurements. They quoted 12-15 bucks, sight unseen, knowing it was a pistol crossbow.

When I strung it I had to use the railing pickets on my balcony for leverage and you could hear the railing groaning as I forced enough bend in one limb to "nock" the string. (I don't have a shop or anything like it in my apartment.) It remains strung, up there on a closet shelf.

It's got a cocking lever, so cocking it isn't a problem, but man, stringing it was a bitch.  

Shoots fine, very powerful, but if you're too close to a cardboard box target filled with newspapers, it will strip the fletching off the bolts.  Good sights, but they are plastic and a little fragile.  Easy to cock despite the 80lb weight, if you keep the cocking mechanism rails lubed with candle wax.
