My guess would be just sloppy machine work like we see all the time out of China.
I have put probably 8 to 10 builds in mine over the last 22 days or so trying to get it to do the same thing. I have used fussed Clapton’s, 2, 3 and 4 strand twisted and regular round wire using 24 and 26 gauge SS 316L wire and mine is showing no sign of doing this.
I would say that the possibility for there to be just a single run of however many they made on one particular day with the wrong settings for the depth the machine was set to cut.
My Recurve does not have a serial number on the bottom so no way to track this issue back to the date of machining.
I do not have the extra time right now to pull my current build but I will later tonight and post a picture of my build deck.
@Suomynona any signs of the other one you have doing this yet?
@AJ17 and @Suomynona just out of curiosity what color are yours that have done this? It should not matter but I am wondering if they did a run of all one color on a particular day that were machined wrong.
Mine is the black version and after 22 days of constant use now the only issue I have had is my cap started getting tight on the O-rings to the point it would not turn. I installed the spare set and working as it should again.
I wonder if this issue is being talked about any place other than ELR? I would hate to think this is going to be a common issue, I really like this RDA and I was planning on ordering a couple more.
@AJ17 I would contact Wotofo customer service like @Suomynona did and get a replacement deck sent to you.
