HELP! Vosper Stabilizer Fin Removal

My 1970 Willard 36 has original equipment Vosper stabilizers (Naiad purchased them some time back). Any tips/tricks to removing the fins?

1. Picture of fin - mechanic has a hand-pump hydraulic press attached but will not budge the fin (see oil is just seeping past the shaft and weeping down top). Should there be some sort of tool or fitting in place (see next too)? FYI - these mechanics have worked on Naiads, and I believe Wesmar stabilizers, so have experience, though are not 'factory' mechanics.

2. Picture of Naiad removal from Internet (attached PDF). I found a decent write-up on removal from someone a year or so ago (may have been this forum, or perhaps Hatteras). They mention a Naiad tool, and mention using a hydraulic press, but I cannot figure out from the description if the tool is solid billet, or if there is a threaded shaft through the cylindrical column, etc. I would think the puller would be a simple long bolt that bottoms-out on the shaft, then pops the fin after a few turns, but the shape of the tool with the smooth cylinder makes no sense to me. FYI - Naiad states there is no tool, so the the mechanic in this original post must have made it himself.

I wonder if Vosper's attachment is different than Naiads? Naiad folks are of little help - just said to use wooden wedges to lever the fins off.

Best thinking is appreciated!
