@rvieceli,
Hey, Ron. Thanks for the questions. Unfortunately, Woodpecjers does not send us a sample, so I would need to rely on the information provided along with the video and photos. Otherwise, I will gladly also reach out to Woodpeckers for answers to your questions.
I can see in the photos that there are metric scales on one side and imperial on the other. Also, I can clearly see that the slots do not go all the way through.
I don't have any information on where Woodpeckers sources components and I doubt they would share that information. I do know that they have full production capabilities in-house, but I suspect they got the extrusions from somewhere and milled and laser engraved them.
High resolution images attached for those interested.
Let me know if you need me to reach out to WP for further clarification on anything.
Thanks,
Shane
