I havew boiled on 2x3 and now use a 2x4 with a blower but the reality is you will probably be batch boiling but with the dividers it allows you to easily draw off syrup as you go I would recommend the dividers.
110 taps W.F Mason 2x3 and two turkey friers for finishing
2011 expanding to a Mason 2x4 with a blower increasing taps to about 200
2011 Hurricane Irene rips thru my small sugar bush cost me to lose 20% of taps
2014 I have reworked my lines for 2014
32 taps on 5/16 line with check valves
57 taps on 3/16 line with check valves
55 buckets with total tapped trees of 144
