When looking for a cleanup of an oscillator synthesis, I found a synthesis which makes a block-on-long-hook-with-boat in addition, as well as one which downgrades the stator of the oscillator as part of the reaction:

x = 221, y = 81, rule = B3/S23

Mark Niemec's pattern database as well as LifeWiki have the same file containing various methods for synthesizing a honey farm. This boat method works:

[A p92 'X66 half' on HWSS gun]


Forgetting that dvgrn had posted a sub-200 optimization just below, I randomly decided to try and optimize this, and managed almost as drastic a reduction:
x = 206, y = 200, rule = B3/S23

Neither is my P142 big A, P154 loafer, P930 10-in-a-row Cordership, P240 crab, P690 27P4H1V1, P120 space rake alternating, and P11040 spider guns in the collection. Are my guns just not notable? These guns are in my user page.

You've done quite a bit of notable gun-building work recently, it ...

P240:

Very nice reduction. The top-left section can simply be moved 4 full-diagonals closer to yield a minor reduction (493x575):

Saves 6 more gliders:...

That's one for the component database, I think. Unfortunately, the repeat time goes up to 613 for 89 gliders:
