Andrew, Frank sometimes may not get emails in his regular folder you may have to send another or see if you can grab his attention on here. I know Frank's had alot of personal life going on and is ready to retire from this aspect of things so hopefully we can find someone to produce these very soon. Heard precision scale was potentially looking at picking them up

I had a chance to test the strength of the 3D printed type H couplers I made and the four I tested all fail right around 35 Oz (2.1875 Lbs). For reference, pulling the dead weight of a scaletrains SD40-2 takes 2.8 oz, so you should be able to pull the dead weight of 12 locomotives before the couplers fail. I also got out five Athearn blue box cars with plastic wheels and tested to see how much force is required to pull them. The force required is low enough that my meter didn't register!
