It doesn't seem to happen on my TC5 as much.
Do you guys experience the same thing with your TC6's? Is there something I can do to help prevent that from happening? Its a cheap fix, so I'd rather have that happen then the arm break or worse, but it just pulls out too easy it seems.
It looks like you are using a shim under the standard hinge pin block. You should use the offset blocks without any shims or flip the aluminum insert around backwards which will act as the shim. I found this was more solid and you don't loose any thread contact. Also as mentioned before, longer screws can help too. I have only had one screw pull out very early on then I switched to slightly longer screws and no problem since. I also notice you are running really high roll center. How's that working for you?
