I apologize in advance for the length of this post. I had a sudden surge of inspiration on Tuesday and Wednesday, and I usually find that I can get a lot accomplished in a short time if I just go with it. I've arranged them in order by synthesis methods, rather than numerically or chronologically.
There was a standard converter (bit+snake to teardrop) that should have been in the automatic synthesis database, but wasn't, so the following three objects should never have been on the "hard" list:

The following syntheses involve flipping the end of a bookend to attach it to something else:

#320 can be further reduced from 24 to 21 gliders by basing it off a boat, rather than a ship:

Using a slightly different spark (that can probably be improved), many forming 16s can be changed into 17s by forming a loop-like projection rather than a hat-like one:
52-glider 16-bit still-life gives us #286 from 56 gliders (final step of both 16 and 17):

Objects with protruding loaves:
Here are some 17-bit still-lifes with loaf-like bonding sites, suitable for attaching molds and jams (I need these to complete the 22-bit molds - I'm not actually synthesizing them at this point, just noting the ones that can't yet be synthesized). #237*, #281, #314, #315, #316, #319 and #350* remain unsynthesized (plus two trivial ones replacing snakes with carriers in the ones marked *).
#375 from 27 gliders. I had actually built this one last March, as an intermediate step in one of the difficult 16s at the time (one that was needed to make 12-bit molds). I didn't record the 17-bit one separately, as the 17s weren't a current concern at the time, and only just noticed it again after making a much more ugly 56-glider synthesis of it!:

The following synthesis is a combination of several useful results falling out of a doomed attempt to create the wrong object, and then building it the wrong way to boot. These two 17s aren't on the hard list - I was trying to make #350 but accidentally put the loaf on the wrong way! Still, a few useful converters fell out of the process. Incidentally, the base 16-bit still-life is reduced by 1 (using the 2-glider claw-to-beehive converter). The beehive-to-mango converter is less obtrusive (but costs 1 more glider). The mango-to-feather converter is much more expensive, but also much less obtrusive.
What's most ridiculous about this synthesis is that the whole reason I went through all the above convolutions was that the standard beehive-to-loaf converter won't work for #350. However, it DOES work for these objects! Building them the old easy way (row 3) costs 41 (w/loaf) and 49 (w/feather), while building them the new convoluted way (rows 4+5) costs 47 (w/feather) and 54 (w/loaf), so the old way is best for the loaf, but the new way is best for the feather:

(Sadly, reversing this to make #350 won't work, as the mango version is stable, but the intermediate feather one isn't.)
The following miscellaneous syntheses are not related to each other:
The recent beehive-to-long-bookend-with-hook converter is very useful, and solves more than .5% of remaining still-lifes, including one 15-bit one (for the same cost as before), and this 16-bit one (that is reduced from 31 to 11 gliders):

Some failed attempts that need further work:
It seems like #143 (Valentine) is closely related to #289 (Half-Valentine? Broken Heart?). A modification of the predecessor for the former gives the latter. Also, the former can almost be converted to the latter (shown are generations 0 and 37):

This is the same as mine, but yours uses a cheaper weld (which should also be applied to #216)
Sokwe wrote:Also, the last step from this synthesis can be used to solve #138. Here are two similar ways to get there:
Sokwe wrote:#198:
See above for completely different ways to do these less expensively.
mniemiec wrote:#214 is listed as solved, but I don't have it in my list. When was that posted, and by whom?
Sokwe wrote:I posted a solution to a related still life on January 4 that made this still life trivial (see here). I actually found the synthesis sometime in December, but I assumed it was already known so I didn't post it. Here is #214 and three related still lifes (Edit: it turns out that this was not correct
):
Last week I was collating all the syntheses I had listed with the unsolved object list, and when I looked at #214, I saw that I did indeed already have a synthesis for it, attributed to you - so this was totally a bookkeeping error on my part.
Sokwe wrote:Here is a similar-looking 17-cell still life that isn't on the list but can be synthesized from 5 gliders (possibly already known):
I had an incremental synthesis for this taking 11 gliders, but this 5-glider one is new to me. This is of particular interest to me at the moment, as I am attempting to list every object (and pseudo-object) buildable from 6 or less gliders. (No, I'm not attempting any kind of exhaustive search by smashing 5 or 6 gliders together, but whenever one comes up, I add it to the lists.) I've currently got ten 3s, a bit over 100 4s, a bit over 100 5s and a bit over 200 6s.
Sokwe wrote:#115 from a constructable 18-cell still life:
Very nice! I wasted a lot of time trying to make this one; I didn't think of starting with a bun and turning it into a snake at the very end.
Extrementhusiast wrote:Either way, #113 from a 14-bitter:
Mine is similar, but more expensive because I've been using a round-about flipper for objects of this kind (e.g. eater tail to loaf) and had forgotten about the cheaper one. This should also similarly improve #250 and #252 (and several 16s).
Sokwe wrote:#211
Mine (above) is similar, but differs starting from the beehive. To get to #211, mine is much cheaper, but to get to the loaf-related cousin, yours is much cheaper - so both paths are useful.
Sokwe wrote:In the same vein as some of the recent syntheses, #122 and #163 can be constructed from 17-bit still lifes that don't seem to be on the list:
I think my synthesis (above) of #122 is slightly cheaper - almost identical to yours but using a snake instead of an eater.
Sokwe wrote:#286 from a 19-cell still life that I think can be constructed:
I count this as taking 61 gliders, which is a bit more than my (totally different) 56-glider direct method (above).
Extrementhusiast wrote:#107 from a presumably trivial 21-bitter:
Yes. It can be made by adding a slide-around inducting block to #378.
Extrementhusiast wrote:#143 from #232:
Extrementhusiast wrote:#232 from an 11-bitter:
Yay! And three weeks ahead of schedule! This also makes #289 much closer, especially if one uses a modified predecessor.
Extrementhusiast wrote:#197 from a 16-bitter:
I did it a totally different way (see above), which I think is cheaper. But I really like this converter! It looks like has a lot of potential for other similar objects.
