Hi Guys, I thought I would show my latest project. As I posted here before,(Universal Standard Crossbow Nut) I recently built three different trigger types and tested them all back to back. I was looking forward to the Chinese type because it's elegant design intrigued me. But I was disappointed with it as compared to the other two types. ( Classic roller nut and my own modern type with a hammer). The main draw back to the Chinese was the inability to cut a deep groove in the front to accommodate a downward pointing fletch.(Doing so would just expose or hit the front fork.) That meant that I had to use 2, 180 degree fletchs or use 3, with two at 180 and one at 90. All my arrows except one are the standard 3 at 120 type and that is what I want to use. Also the sample I was testing made a load CLACK sound when fired. But I expect that was an issue unique to that sample as I haven't seen that on two other examples that I built. At least not so much.
I want to do a semi modern build with this trigger type but the above would be aggravating.
So I am experimenting with an improved version. I basically, lowered the front fork pin, and adjusted the geometry of the other parts to accommodate. I went with the bolted together claw assembly just because it is easier to machine and seems to work fine. You can see the dropped fork pin in this photo:
And here is the claw assembled:
You can see the front groove for the down fletch in this picture:
It will now accommodate any of my arrows.
Here is a shot of all the parts:
It seems to work well just testing it in my hand but I have yet to test it in a Xbow. I don't have anything I want to mess up by taking apart now, and the new bow I ordered to do a build with this trigger is back ordered. So I am on hold until it arrives. I have a bunch of work travel coming up so it will likely get there the day after I leave.
I leave next weekend for two weeks on the road. (on my motorcycle if the weather holds in Tulsa and Albuquerque)
But I will post a follow up once I get it shooting.
