Man, that's a beauty! Great design and workmanship and an excellent job on the post. Thanks.

Two questions:
1. What is a cost estimate for the solenoid-spool valve?

2. When the thumb and bucket operate together do you have a noticeable slowing of the bucket speed compared to when the thumb is in a fixed position (and the bucket is getting the full flow of the pump)? It would seem the bucket would move at about half speed when moving the thumb (if the thumb and bucket cylinders were about the same size).
