I chose to cast, as the store is very far from my home. Thanks for commenting

Thanks, Celsoari for posting - nice finish and seemingly no gas pores in your cast?
For degassing I use a teaspoon of "pool chock chlorine" in a foil wrap and press it to the bottom of the crucible,
flux isn't really necessary for my alloy of choice.
-Don't chlorinate without a proper face shield, gas mask, apron & gloves though...
One thing I wondered, as your aerating your sand seemed to be a dry & dusty job:
-Are you using your greensand entirely dry?
I get very nice finish with my sand just a bit moist as per Myfordboy's and Olfoundryman's recipes:

When it comes to repurposing old Al casts I can recommend scrapped Al car wheel rims,
motor and transmission parts, table stands and office chairs
(those 5-star castor chair feet provide 5-6 lbs ( a litre) of alloy each)...
Keep up the good work and good luck!
Cheers

I use slightly moist sand.
use this aerator too, similar to the image you posted. For degas I use magnesium sulfate penta hydrated (Epson salt)

Beautiful work once again my friend Celso!

Strength depends on the composition of the scrap used in the melt pot. If you use chunks of damaged wheels (cleaned & no powder coating) it's bound to be strong enough for most workshop castings.
