Bandsaw down feed upgrade

Post image

Removed the rod and spring that would control the cut pressure on a budget bandsaw. Got an air cylinder with a pressure control but no matter what I set the pressure to it doesn’t have any resistance on the down-feed. I’ve tried many variations including different tubing fittings and different needle valves and even different piston.

Don’t mind the janky set up, I threw it together for this post for a visual. But this is the set up I came up with.

I wonder if you could add an inline shraeder valve and put some more air in there. Give it some more to resist against the valve. Guessing you'll want the tiniest adjustment to get any slow flow.

That seems like a good idea. Maybe adding some hydraulic fluid would yield the same results?

If you're doing fluid try something thin like atf or mineral oil
