Allen Hall 2025: Soren, welcome back to the podcast. 

Søren Kellenberger: Thank you, Allen, and, uh, nice doing it, uh, face-to-face- Yes, it’s great … and not as a team, uh, call. Right. That’s 

Allen Hall 2025: true. Yeah. You’ve been doing a good bit of traveling, and you’re the new head of CNC Onsite. 

Søren Kellenberger: I am, yes. 

Allen Hall 2025: So congratulations on that. 

Søren Kellenberger: Thank you very much. 

Allen Hall 2025: And all the exciting new things that CNC Onsite [00:01:00] is doing, plus all the things you have developed and are now out in the field implementing, the, the list goes on and on and on.

I’m alwa- every time I talk to you, “Oh, we got a new-” Yeah … “machine to do something uptower.” So it’s all uptower, which is the, the beauty of CNC Onsite. You’re thinking about the operator and the cost to pull the blades off and do lifting the cell off and all those things. If we can do it uptower, we can save 30, 40, 50% of the cost of a repair.

Søren Kellenberger: Yeah. 

Allen Hall 2025: That’s where CNC Onsite is just really killing it. You guys are doing great. Thank 

Søren Kellenberger: you. Of course, we like what we do, but, uh, thank you. 

Allen Hall 2025: Yeah. Yeah. Yeah, yeah. No, it’s good, it’s good. And, and so w- let’s talk about the things that I know about, and we’ll start there, and then we’ll go to all the new things you’re doing.

So the one that I see a lot of operators asking about is yaw tooth. Yeah. 

Søren Kellenberger: Uh, 

Allen Hall 2025: deformations, broken teeth on the yaw gear. Th
