Now we need a suitable rake to make a wickstretcher
You’d need a lot of rakes since Freywa didn’t even show the intermediate steps, so the component that is shown there may need to be a tad more expensive.
There are only a couple of intermediate steps not shown, and it's just adding a blinker and turning a tub end into a boat end. Here are a couple of full cycles, not completely optimized but probably reasonably close:
Code: Select all
x = 205, y = 187, rule = LifeHistory

There's one serious problem with a design like the zigzag wickstretcher. That recipe was carefully designed to build a chunk of zigzag that repeated every 30 cells, so that c/2 period-60 rakes could be used to build it.
By contrast, the above recipe only moves upward by 8 cells every 100 ticks, or c/12.5. We can't easily speed up the construction by building multiple sections in parallel, because each section has to be completed and cleaned up before construction can start on the next section.
I didn't really try to optimize the recipe, so it's possible that adjustments could be made to allow the recipe to be fed by 8c/80 rakes, in which case maybe something could be done with copperheads and fireships. (?) Otherwise, it would probably make more sense to use slide guns to build this wickstretcher, similar to Golly's Life/Miscellaneous/blockstacker.rle.
Rakes supplying the glider recipe in the form shown above would have to travel slower than c/12. Unless I'm missing something obvious (which I might be, but I don't think so) we'd have to use something ridiculous like Orthogonoids to produce gliders slowly enough at such a low offset.
