200L Grain Storage with valve for $55

[buckerooni]

OK, make that $60-$70! So this is really needed for my missus buckwheat hulls in the shed but I might make another one for my ale grains

The idea is:
- store a large amount of hulls/grain in a rodent proof vessel
- gravity-fed dispensing

What I'm thinking - a drum with a tap on the bottom, elevated from the ground
- 200L plastic drum - $10 each - https://www.facebook.com/marketplace/item/302107953627989
- 50mm bulk head - $19.20 - https://www.ebay.com.au/itm/Tank-Fi...gation-Poly-Fitting-Water-Hansen/272770838522
- 50mm PVC tap - $11 - https://www.ebay.com.au/itm/PVC-Bal...-BSP-50mm-2-Stop-Valve-Tap-Valve/272492964847
- 50mm hose tail - $5.30 - https://www.ebay.com.au/itm/Hose-Ta...gation-Poly-Fitting-Water-Hansen/282580704231
- 50mm hose - $15 from somewhere

so, all up $60-$70 in parts, with another possible $10 in postage and have to pick up the drum.

It would look like this:

Any feedback/thoughts/suggestions/improvements on this?

Thanks!

I know nothing of buckwheat hulls but would they "flow" through a tap like that? Perhaps something more like a honey tap?

Seems reasonable, I wonder how much mass you'd need in the drum to overcome the resistance on the tap for gravity feeding? ie, when will there be too little grain to flow out?

Rats will eat plastic. Steel is the only really rodent proof material.
