No direct edgy X-to-eater factories are known. It's easy to build a circuit that synchronizes a couple of gliders to build an eater so that it blocks a glider lane -- this is done in the

stable universal regulator, for example -- which still needs to be rebuilt to do the synchronization more efficiently. It doesn't have to be set up so that the lane that is blocked is the same lane that triggers the reconstruction of the eater.

Fishhook eaters are pretty rare, and any other object with glider-eating capability is even rarer. For a direct glider-lane blocker factory, is it allowable to catch the glider and make a boat-bit (so that aircraft carriers, snakes, etc. would also be possibilities?)

There are other kinds of permanent switches that have the effect of permanently blocking a glider signal, though. Some of them also allow the signal channel to be re-opened with a single glider (equivalent to shooting down the eater after it is constructed):

You can use other H-to-Gs at the end, and/or add a few Snarks to put the output glider back on the original lane -- depends on exactly what you need this glider-lane-blocking mechanism for.
