spring blade rests

[geoffretired]

I have tried most types of rest.Fixed and drop away. I have never used a spring blade rest. Of the rests I have tried they all have one thing in common; the springiness is limited to downwards. In other words, the rest can spring down below the initail setting, spring back to initial height, but it cannot bend back higher than that.The spring blade type, however, can, if depressed, spring back and end up higher than the initial set up.As the blade is the only moving part, I guess the speed of return will be quicker too.
Could this be the reason that gets the improved results for some?

TYhinking about it, if thje blade springs up to more than its original height then there is more chance of contact. I have a spig rest set up at the moment as a spring rest and the weight of the arrow on the arm causes it to sag a little below its original position. Being some what new to unlimited I set the height up so that when the arrow tip is resting on the arrow rest it is level with the center. shot a bare shaft and it was the same height as the fletched shaft so I left it at that.

Hi Jerry,
I know I replied to your post yesterday, it seems to have disappeared. Thanks again.

I think that the secret is only 1 moving part means consistency. Fewer things to break, adjust or wear out.

However, if the blade breaks, (and this is usually on arrow # 58 of 60, in a head-to-head competition where you are - or at least were - ahead by a whisker...) you need a replacement blade that you have already checked on the bow for consistency. This is courtesy of a good friend of mine that had this happen. Never happened to me, of course!

Matatazela, that makes sense. Simpler idea than mine too. MMmmm?

[Matatazela]

I just have no clue about all the physics and mechanics. I like simple, like me...

In my admittedly limited compound experience I have found that a spring steel launcher on a normal (in my case QT3000) rest gave better performance, particularly forgiveness wise, than prongs. Am I alone in that?

[Matatazela]

Launchers are definitely more consistent than prongs. They bounce my arrows all over the place (at least that is my best excuse for poor groups!)

[geoffretired]

Prongs can cause some archers to experience poor arrow flight. I sometimes wonder if the arrow gets slightly "stuck" in the gap and then needs a bit of a big push to get it going again.

Not just me then... I shot quite well outdoors with a spring steel launcher, then very badly indoors with prongs, but my alu arrows were too heavy for a spring steel launcher
