How to Trigger SCRs in a Full wave AC/DC rectifier?

I have a Full wave rectifier using 2 SCRs and 2 diodes to rectify AC to DC with adjustable voltage. My problem is I do not know how to trigger the SCRs. Does anyone have a circuit they like?

I saw this website: http://www.allaboutcircuits.com/vol_3/chpt_7/5.html

Where they advocate using a resistor and diode to trigger the SCR however I don't think it would work for me because my SCR:

States on page 2 that the triggering pulse must be less than 1ms. So if I trigger them early in the cycle to say get 90% voltage my triggering pulse could be well north of 6 ms. Or am I thinking of this wrong?
