D/C, the wood was plenty heavy enough, your grain was running the wrong way. I got away from the solid mounts and switched to a strap, I like it a lot better.

I'm having a tough time imagining a strap that keeps the bow from flopping around. Picture maybe?

    The strap only holds it from coming toward you, it has to be backed up by something solid. I will get a pic tomorrow. I threw together another shooting machine a few weeks ago but plan to rebuild it very soon. The strap is the only thing I like on it. I really like Allens latch for the release.

I'm waiting for a picture of Allens release. I'm not sure what a rotary latch is.

  I looked it up, a lot like a door latch in a car or truck. I have some 1 1/4" delron rod, I am going to try and build your style latch from the Delron before I go to the rotary. My compound release I done really trust past about 100#

Yeah, I just did too. Hood latch is what i thought of. They look like they would work all right.

There's a point that is easy to overlook and isn't intuitive.
You want the release point to be quite a way above the track to avoid the string slapping the track*, as there is a lot of string vibraion and arrow flex especially in flight bows.
I can take detail pics of my set up if anyone wants to see anything specific. (Not that I'm claiming my one is anything special or in any way ideal  ::) )

Thanks Del :). Why did you use the leather tab on the release?

This shows a before and after conversion of what I did with this small rotary latch.  Depending on the latch, the modifications don’t have to be this complicated.  I ground a notch in the latch to act like a hook for the string loop, but the hook could just as easily be placed directly on the bow string. I put this latch in a housing that slides on a piece of t-track. The trigger piece behind it also attached to the t-track, and I slide this to the position that I want to trigger the release.  The latch slides back and pops open as soon as the latch release lever contacts the plastic finger on the trigger.  It works great every time and doesn’t fail for thousands of shots at very heavy draw weights (unlike many compound releases). It is a very smooth, reliable, and easy to adjust so i am pretty happy with it.

Just trying to simulate a manual loose, and in the hope that it would be less harsh with less string vibration. I think the string was maybe slipping off the nut before it had rotated fully (not sure it was rotating fully, so I tweaked it).

   I really like your set up Del, I like the idea of flight shooting with a machine when I get too old to draw the bow.

  Allen, what was the intended application for that latch, would you select the same one if you did it over?
