Indoor 4 feet flow trough vermicompost bin plan

Hi everyone,

I thought I'd share the worm bin plan I've just made. Critics and suggestion are welcome!

This design has a low height so it is easier to empty a compost bin in it and also because it will sit in a basement that is less than 6' height.

I didn't put a top panel because I was thinking about simply putting a plastic sheet (the black and white plastic that is used in some grow tent.

I will also add a plastic liner (same black and white as I would put on top) on the plywood  to prevent the wood from rotting.

What will cause the castings to fall through the pipes at the bottom?

Yes!

You can look up flow through worm bin harvest. I forgot that I thought about making a tilt in the plywood floor to make the harvest easier...

use a rake or three finger garden weeder from the underside to scratch between the pipes

Basic design looks good. Make sure your dimensions minimize the scrap leftover. I can’t read the dimensions from this phone.

So I've ran into some issues.

First off, it is not 24x 1/2 inch pvc pipe, but 22x 1 inch pvc pipe (little mistake). That being said, I recommend measuring the actual outer diameter of the pipe as it was actually 1inch 1/8, which is big enough to not fit 1 inch hole. I've started drilling half of the holes before checking out if it fit (which it didn't). I only had 1 1/4 inch bit to make bigger hole and drilling into 1 inch hole has been hard on the impact driver and the drill bit. I've actually broke the bit, not the cutting end, the other end. These are the flat kind of drill. I drilled in reverse into the already made 1 inch whole and went kinda slowly to be able to make the bigger whole. It made a nasty job, but it seems good enough so far.

Another tip for drilling, place the 2 pieces on top of each other and clamp them to drill both at the same time.

Now I only need to assemble and see how it goes.

Looks good.  You must have a lot of stuff to compost.  Depending on how wet you keep it - and I am very pro-wet bin - you may find you need to remove some of the pipes in order to have the compost self-harvest or harvest easily.
