Duel lines

[spud]

I was reading an article from PMRC about duel lines for your lats. The studies show they were getting close to 40 gallons of sap per tap. It said they had a spout video but i could not click on. Where do i go to get more info on this set-up?

What i was reading was (over sized lateral lines and fittings with modified spout base). Dr. Tim do you have more info on this? It sound like it would cost a lot to set up a woods this way. Would it pay? Thanks

We are researching both approaches (dual 5/16" lines and oversized lateral lines). No more to report yet. We need time to determine: does it produce more sap, what problems occur, and is it economical?

Thank's Doc.

Please keep us posted.

Do you have a link to a video on the dual lateral line system?

I run 1'' mainline with 1'' lats w/ 5/16 lats off of those(10' or less on these).
