Mel tell you what is Fascinating is , now stop and thing for a minute what I am about to say . How the heck did they know to get metal from a stone ...... a stone is a stone. Ok my thoughts are when the builds fires they would have stones around them to hold the fire in place . One of these stones got to hot and metal came out . The first metal was copper . So a piece of copper ore it must have been . We had three periods of time . The copper age. Now that is not talked about a lot . The the bronze age . Then Iron age . Ok so they got copper . But on its not strong enough so they introduced tin . At that time they were only using logs to burn. The iron age only came about when they found they could burn coal as it got hotter letting iron ore melt. logs/ wood . Could not reach the heats to melt the iron ore . So that's how the periods came to be . One of the main reasons the romans came here was for copper/ tin and lead . Heating metal is fascinating .

I totally agree , I also think about the discovery of glass in a similar way (although glass wasn't as world changing ) . Quote Link to comment Share on other sites More sharing options...

Bowlander Posted October 27, 2020 Report Share Posted October 27, 2020 Aluminium transmits heat very , very fast ! For that reason and its low melting point we consider it none forging . You can hower cold work it but you need to keep annealing it by putting oil on it and heating it with a module flame as it work hardens Machine out a billet of a reasonable grade will be the answer , oh don't bother grinding ! Just machine , then finish with a file made for ally which only has single line cut . Going to be a ****** to buff if thats what your client is expecting , even if you do it will just oxidise, so shiny means off to the anodising plant I suspect Quote Link to comment Share on other sites More sharing options...
