Don't know if this has ever been posted in here but this is what I did for my first false bottom and it looks awesome and its very cheap to build probably 25 bucks. I wasn't able to find the brass tank connector at lowes or home depot so I just used a stainless hose clamp to hold it on there. Here is the link on how to do it. I cannot take credit, I just found this.
