    I'm planning to use tension pins for the roller nut and the trigger on my crossbow, the size is 3/16 x 2" would this work. Also my home made crossbow will be in two parts so that the mech section will be open for repairs.

    I'm know expert but, I have had a bad experience with split pins. I think they would be one and the same. In my case I was using them in my lock for stop pins. and three out of four were cracked in half .They are almost hard as glass. Where  you are dealing with the kind of power you have here i would stick with a solid axle, say about 3/16 or so. Since my problem I've switched to 1/4" shoulder bolts and really like them. When playing  with these crossbow you have to treat them same as a loaded gun. Don't make room for an accident and you won't have one. Above all have fun and enjoy the build.I look forward to seeing pictures.

    After I posted before ,I just now remembered there are two kinds of pins. One is spiral wound and one is just spit the full length. Just the fact that they are called tension pins, I think they would be finicky to size right. You know, tight in the frame loose in the nut. I 'd still stand by my first call though.

    Thanks c sitas for the reply. But maybe I need to be more up front about the tension pins they are made of steel and thinking of putting a threaded rod inside it, that is if I can find the right size rod.

    Also down the road, I will post pictures of my build, and maybe add some wood carvings to it.
