Wow

Firstlight · April 04, 2014, 03:41:00 PM

well, that was interesting. I wonder how many dry fires a typical bow can take?

Well, zay are ze Germans no? LoL. Neato. Those bows seem like a great value for the money.

TxAg · April 04, 2014, 03:50:00 PM

Wow, 72 dry fires

i cringed every time he released.

cool video, I have read before that hoyt dry fire tests their limbs also. I think 1000 times was how high they went

Interesting...I wonder how much that black bow holder (at the handle) in there helps?

It is large enough that the string must also hit it taking some of the force and energy from the bow limbs.

I ask because every time I see something like this, I always wonder where the energy is dissipated and how a device (like the bow) absorbs the near instantaneous forces that are not supposed to be there (or are not there when an arrow is launched).

Nice video! I wonder how many #s that bow is?? That bow shop is awesome! lots of nice tools ..This pic is of a 46# @ 28" D/R hybrid longbow I built 3 years ago has been dry fired over 40 times by its owner.. The string in the picture was one of my "shop" strings I use to tiller bows and try them out after finishing..It typically has a skinny endless loop D97 FF string built by LBR with no string silencers. Limbs are 040 glass, actionboo tapers and 024 zebrawood veneers, it has no stress marks or cracks. She still shoots it when she is not shooting her new Olympic style bow.

I, too, was wondering about the bow holder not allowing the string to complete it full forward cycle, thus adding an additonal layer of forward stress.
Still impressive and that shop make me drool.

thanx for sharing

A bowyer once told me that a good bow should be able to handle a dry fire without issues. He said a lot of bowyers say that the bow can't take it to give themselves a warranty out. He may be right, but that video still made me pucker

Archie · April 04, 2014, 05:21:00 PM

I'd be interested in knowing how that bow performs. Seems like a bowyer could make a bow that would withstand a lot of dry fires, if he was willing to sacrifice a lot of performance.

A couple of years ago I blew out the top tip on my Black Widow recurve in an accidental dry-fire, from full draw (31"), on a 62@31" set of limbs. Dragged the tip of the bow about 2 inches through the fiberglass into the limb. Bow never unstrung, and remained all in one piece. Wasn't a good day for me though.

I had an old Bear Kodiak that didn't survive one.

Two observations:

1. I only saw 7 dry fires, and the way it was edited, only 3 in a row at best. The guy might as well write 172 or 1700.

2. Why was he afraid to hold it?

I have dry fired my sarrels a couple times due to nock failure. No damage yet, but no way I would try something like that!

It does look like the black piece holding the bow is absorbing some energy, and the editing made it difficult to see if they actually dry fired it more than a few times, but.... It's a pretty sweet promotional video.

I got a kick out of it.

Being that Bodnik is not a sponsor is it fair to criticize them without allowing them to respond ?

bowfanatik · April 05, 2014, 02:18:00 PM

This man on video is master bowyer of BearPaw. You think that is fake ?
That bow is just good, accept that

Cootling · April 06, 2014, 12:04:00 AM

Looks like a nice, professionally produced video by a reputable manufacturer. Criticism seems unwarranted.

motorhead7963 · April 06, 2014, 12:12:00 AM

There are always the NAY sayers and pick something like that apart. I would say for the sake of time they edited it. Bearpaw makes some Quality stuff. Think about this have you ever dry fired your own bow? did the string hit you in the back of the hand? I haven't ever dry fired my any of my Bows(thank God) but I think that is a non issue (JMO) What I would like to see is that test done on a Heavier bow say 60lbs? Now that would tell you something. I have never held or shot a Bodnik Bow, but if there willing to video a dry fire test on one of there Bows, I might have to check them out. Looks tough enough to Me....
