NW Leicestershire (LE67) I can spare half a dustbin full.Surrey, possible a tad too far.
Mansfield sand it is then

Only to get what I have reduced down in size so it can go in the pot, just to get going I will probably wizz some down with a bandsaw.I didn't realise you were just looking to make ingots, would it be worth getting some pig iron moulds (first hit on google)

Thanks for the offer I will give the pit a call tomorrow and see what kind of deal they can do on some delivered

If you've got'em, crank up the stick welder using a big mud rod and melt through the wheels like a Jedi knight with a light sabre. Did that back when I was in High School, and it was surprisingly quick cutting through an aluminium engine block.Only to get what I have reduced down in size so it can go in the pot, just to get going I will probably wizz some down with a bandsaw. ...................................

That's why I suggested pig iron moulds for making ingots, saves making moulds from casting sand, just fill them and knock the ingots out when cooled then re-use.He's not. Last time I spoke to him about this he was looking at a big furance / sledge hammer to smash up the big bits of ali so they could be melted into ingots / purified for further casting at later dates on a smaller scale. Easier to work with ingots than 20" wheels nicked from the local gentry's Range Rovers by the gypos across the road
Thats what I am doing but it wasnt part of this thread , building a big melter to get the big Ali lumps like heads ,gearboxes and wheels into ingots so I can use them in my small furnace for casting. Scrappy down the road built one that ran on waste engine oil, melted everything into ingots and raked out all the gears and valves etc when the ali stopped running, that ran into steel molds.You just need a big melter. Then pour into something suitable for remelting. I've made a melter out of a big propane bottle, that will take engine blocks,
Messing around with sand to make ingots is just daft imho, especially if you have as much as we both seem to have to melt?
Perfect! I'm collecting tins from all over...Thats what I am doing but it wasnt part of this thread , building a big melter to get the big Ali lumps like heads ,gearboxes and wheels into ingots so I can use them in my small furnace for casting.

Also consider looking for metal muffin tins at charity shops as they usually have eight or more compartments. I remember my Dad used these for making lead ingots, so should work for aluminium too.Perfect! I'm collecting tins from all over...
Guy at the boot fair is selling these for 20 quid Bob. Must be 100 of them about 9 inch diameter and just over an inch deep
muffin trays: pour ingots, wait 5 minutes, tip out, reuse. You could even use a bit of water to cool them quicker if you’re impatient. I find the round slugs are easier to stack in the crucible and quicker to melt than blocks. You’ll want to keep the crucible half full so it doesn’t freeze as you add more scrap so you’ll have plenty of time to recycle.Yes, they would be îdeal, but I would need dozens of them. I even looked at Chinese sellers.
For that money they are worth grabbing, even if only for parts trays when working on kit. I was looking at what I typically need to cast and the biggest thing is less than seven kg, if I make ingots of 2kg in brick shapes they can go straight into the crucible I have with no further messing about. Checked out the grade of alloy typically used in ali wheels and in the main its A356 which would appear to be LM25 which is exactly what I want.
Done a bit more research on smelters and think I have come up with a plan, waste oil burner bits have been ordered and should be here shortly, another propane bottle is about to bite the dust
