Brenden - If you're asking about harvesting the castings, I used to sift out worms from the castings tray by tray (worm tower with 4 active trays) but that took forever and gave me a sore back. Here's what I do now. Spread a big plastic garbage bag on the garage floor. (I don't have to watch for rain or hot, sunny days.) Dump all 4 trays into a pyramid, just as you referenced. Have some light (real or artificial) shining on the pyramid. As the worms dive lower into the pile to escape the light, I pull off the top layer of compost and pick out any big undigested bits of food or newspaper (but not really necessary). Go do something else (usually in the garden) while the newly exposed worms move even lower into the pile. Repeat as needed. For me, it's a multi-tasking opportunity and not so boring and time-consuming.
