I want to make arrows for my bow that making, i have an idea of making a wooden mold and then finding the melting point of aluminum foil and melt it, prob is that i dont have anything to melt it with my moms oven goes up to only 500F and i need one up to 1240F
Its relatively viable to soften aluminum foil. The Adiabatic temperature of a traditional gasoline flame is 1950C. The oven backside is in shut proximity to the flame so its temp will likely be a lot hotter than the air temp of the oven. Although you consider simplest half of this temperature to account for other temperature losses you are still 300C over the melting temp. While you first activate the oven the flame get turned on at a max price and stays on except the oven warms up. Because of this the backside of the oven will get much hotter than the oven environment. Remember shopping a substitute phase for the detachable oven backside alternatively of an complete oven. You could additionally are trying taking away the backside taking it outside and use a propane torch to remelt the aluminum and wipe it off with a bit of steel wool once its softened up.
Buy the arrows. It is cheaper and probably safer.
Forget it. 1. Molten aluminum can burn in air. 2. Molten aluminum will set fire to a wood mold. - (Wood catches fire about 450 F.) 3. You haven't a clue how dangerous molten metal can be to handle.
The wooden mold will not be able to handle the molten Aluminum. You will need a foundry in order to melt down the aluminum properly, and some shop equipment to cut the arrows out of the mold. It would take an inordinate amount of aluminum foil to make an arrowhead anyway. Typically you want to melt down aluminum that is higher quality (old aluminum doors for instance). Anyway, try taking a class in foundry, it will teach you what you need to know. Do you have such a class in your High School or local community?
It sounds like you could be re-inventing the wheel here. You know you can buy aluminium rod and tube from Ebay suppliers? It would be a lot easier to make some arrows from that. If you are looking for a light and strong material, look at carbon fibre rod available from model aircraft suppliers. It's a beautiful material, unbelievably strong. I think it would make great hi-tech arrows, and it doesn't bend like aluminium.
