So, been building this target changing system now and I have it working quite well.
The big issue has been the cord which actually drives the trolly back and forth. You might not be able to see it but there is a fine fishing leader cord fastened to the middle of the black Kydex trolley (thanks @bigegg ) and going from one end, around the pulley at the backstop end then all the way back to the firing point, around the motor pulley and then to the "shock absorber" of the spring fastened to the other side of the Kydex trolley.
This is a bit femme and I would welcome suggestions as to alternative solutions. What does NOT work: fine bowden cable, even the thinnest is too heavy. Fishing line, it stretches. Paracord, forget it, it sags unbelievably. Any ideas?
