    Given that for most people, "common sense" really means "your opinion and my opinion are the same" I'd say no. Since it's your son you had a chance but if he's 17 already it's a little late for easy...

    There are zip ties with a little lever on them that can be released and reused, but I did a quick search and didn't find any that were much larger than 12" so I didn't think they'd be large enough....

    You got murdered on the tin, unless you meant $1/lb and even then you got shorted. Unless there's no market for tin scrap, last I checked it was worth more than copper.
