shooting fixture
avcase:
I think a couple more pictures would help. If you really want to get fancy, you can pick up a piece of “8020” T-track extrusion, and get one of the 8020 linear slide bearings to attach the rotary latch release to. 8020 is like the ultimate lego set for big kids. We use it all the tine at my work to quickly construct all kinds of test fixtures. I use it for the shooting fixture for my bows when I test arrow performance at the Alvord dry lake bed every summer.
You can probably come up with modifications to the latch to simulate a finger release also, if that is important. I imagine you could fasten or weld a more blunt “hook” that would give more of a sideways deflection of the string upon release.

like this for the square 4 slot tube?

that 80/20 kit looks like the way to go, but so far I have just been using scraps of plywood and unistrut, you got me thinking though. right now the snow is deeper than the arrows are long, so Its a good time to work out some designs on the sketch pad.
avcase:
Those are not cheap, but they are sure nice and smooth and used for very precise and durable sliding fixtures. I made my own t-slot slide by milling out a piece of HDPE plastic using my table saw, and it works pretty well for my needs. Will get a picture uploaded.

Tuomo:
Thanks Alan for the information! Rotary clutch seems to be nice idea and especially the 8020-system. I think that I will make a new shooting fixture. It would be nice to see your shooting fixture, because I think it is quite well design.
avcase:
I love the 8020 system. I made my endless loop string jig, bow weighing fixture (for our flight shoot events, and many other things out of this. My regular shooting machine is all in pieces right now, but I will need to get it operational in the next couple of months in order to test some new Flight bow designs before I send them out to the archers who will be using them. I rarely re-assemble the shooting machine the same way twice. I configure it on the fly depending on the types of bows I’m testing, and the types of tests I am performing. For example, it will be configured a little different for test shots in the field where I am more co corned about measuring arrow performance, Vs. tests in the workshop where I am chronograph testing the bow.
