What we got here is a behemoth of a boat. This guy is 110 pounds, 27 inches. And we reinforced this thing. It's got a solid FR4 riser. Most people will know this material as G10. I made this into a two piece. I reinforced it with carbon throughout. It's got layers of carbon socket and tenon system. We're going to be taking this bow, tuning it out. It's partially tuned. Tips are done, riser's carved. We threw together a mech mechanism for shooting it because none of us can draw it here. But I got to finish tuning it first. So that's where we'll start. So we're going to string this up and we'll check it, make sure. I think it's just a little bit crooked. So we'll straighten that first of all. Just a hair out to that side, which is where I had it marked. Just a hair out to that side. We'll take just a little bit off of that on the trap. We'll do that right here. Double check that. See what we did? That straightened up real nicely on the lower them. Oh, and then a. To take a little more off. Top limbs. Still needs some better. Check the weight on this thing. Make sure I'm still okay. Yeah. Check the tiller here. Feel really good. Oh, wow. Drop it. Drop it. Drop it. We ain't playing if you don't drop it. Drop it. I just have to adjust the tiller a little bit. With a heavy bow like this, you don't have a little tiny bit of action on really on. Removing material changes the weight drastically. So you have to be super careful. A little tiny bit more. Okay, that's perfectly straight now. Seriously, bro. Okay, that'll work. She's tuned right now. We'll take out the scratches here real quick. And then we're gonna shoot it. This pneumatic sander here runs at 1745 RPMs. With that kind of speed, you're. You're sending a bow limb and say you catch it like on here or you catch it down there. A quarter of a second will dig an 8th inch hole. It's a very scary machine. That's why Nick can't run it. Here we go. You better count these strokes. Very, very trying to get his ball. He got stuck under there. Oh, he got stuck under there. Nick, how close are you to being ready for that thing? Good fit. Oh, man. He's not quite ready. I'll take the sleeve off and we'll get that machined right.
