Do me a favor, go to an auto body shop, have someone hand you a piece of steel, try to bend it, then have them run a torch very quickly over a piece of metal and try to bend it, not only does it quickly become mailable, long before the melting point, but if you put enough pressure on it, you will get a crack line.
It is amazing how many of these ‘truther’ sites can be debunked by visiting something as simple as an auto body shop.
Should have pinged you on 314
Or a blacksmith shop. Which may be a better analogy for these 19th Century wannabees.
