Is it possible to make a simple charger of my own to recharge 6V lead acid battery?

LM317 application notes show how.

So if i make one using LM317, won't i need a transformer(like one used in rechargeable torch lights with Lead-acid battery)?? Can it handle the current from mains? I mean to say won't the high voltage will damage the circuit??
Yes you will need a transformer and supply it with DC 7 to 10 volts should do.

the LM317 controls the charging current - Lots of information on the LM 317 dta sheet.
