If you have the clearance on the jointer side to position the feeder as shown below, I think you¡¯ll find this makes raising and lowering it a lot easier.

A lot of the forces and balance depend greatly upon where you position the feeder when you are tilting it up and down. I have the smaller 3 wheel feeder, F38 and it still isn¡¯t too powerful when I have it where it needs to be. I took a sharpie and marked alignment marks on the vertical post for rotation and the over arm tube as to where it needs to be for the best balance point. When I have it where it needs to be, the thing is fairly neutral with just a little down force required to park it in the down position.
I moved the bracket down lower so I could easily mount the spring (only had to compress about a 32nd of an inch) just to see how it would work. For my feeder I think the spring is too powerful. I can only bring the feeder about half way down, even if pushing on it with my arms to add more force.?

The picture shows as far as I could push it down.??

If I get an underpowered spring, the only issue is it won't assist as much with the lift, right? I'm thinking better to error on getting a less powerful spring when I order the new one. Maybe 100lb of extension force, which it says takes 132lbs of compressive force vs 330lbs for the 250lb spring.?
