Following are photos of the cutting speed control for my copy of the ubiquitous 4"x6" bandsaw. I thought about and discarded the idea of building a bracket to compress the cylinder on the cutting stroke. This would give the advantage of moving more fluid for the same distance, but would require a lot more work.
Instead, I decided to slightly reduce the thickness of the spring mount to accept the cylinder yoke, then made a shoulder pin for the rear yoke, to mount through an existing hole which I enlarged slightly and counterbored to accept the pin. The reservoir is a 4 oz. model airplane fuel tank. The reservoir mount is just scrap steel drilled, bent, and painted.
The pictures are as follows:
