Assuming the 1 amp charging rate is critical, the only way to make that happen is to adjust the input voltage until that 1 amp rate is reached. It's likely to need adjusting throughout the day, so there would need to be some sort of feedback loop to adjust the voltage and charging rate automatically.

I'm assuming a simple battery minder type charger would do perfect. Some auto parts stores keep their new to-be-sold batteries on these chargers all the time. If you're good friends with one of these stores, ask if they can plug your battery in for a day. Of course, if you bought the battery somewhere else(online?), I can understand you being a little embarrassed to ask them for favors...

The only route I can see to charge it cheaply and manually, would be to use a ammeter(from a early squarebody), a variable resistor, and a 15 volt power source of some sort(possibly an old fashioned non-automatic battery charger). Set the thing up in your basement on a saturday, and adjust it every hour to keep the ammeter in the 1 amp range.
