No, those came from 3 Rivers. I just simply do not have time to make them! If I had CNC, it would be a lot faster.
I'd like to see how you do the plate adjusters.
Longhcruise. I drill in from the side with the mill and tap for I believe it is 6-32. Fill the hole with super glue before tapping, and redrill and tap after it dries.
The super glue soaks into the wood and stabilizes it. I use an extra long set screw. From my tests, it will round the Allen wrench out before pulling threads using the long set screws.
They make a brass insert but do not want to do that just yet.
We will see how they hold up.
