Northern Brewer:

I used a rotary file and cordless drill to enlarge the center hole slightly to accept the rigid copper pipe which is about 5/8" OD. The stock hole is only 1/2" diameter.

Catt- Weren't you the guy who built in the "lifter" for the FB? After most of the filtering was done and the FB had collected the bulk of the hops, someone made a hook that would lift the FB and allow the wort to flow past.

Yes, but it turned out that what I thought was a clogging problem was not. What was going on was that the FB was not held down as firmly as I thought it was. There was too much slack and some small amount of leaf hops passed under the edge of the FB. These got hung up in the pump head outlet which halted the circulation. The fix was to slightly modify the pickup tube so that it held the FB down more securely. Took me awhile to figure out what was going on as the problem was not obvious. I no longer need to use the lifting rod.

I'm thinking about doing the same thing but I can't seem to tell the difference between these two...
ABT Large Hole False Bottom - 1/2" hole no elbow : Northern Brewer
and
Sanke 11.5" Stainless Steel False Bottom - False Bottoms & Screens - All-Grain Equipment - All-Grain Brewing

The one from NB costs more, doesn't have an elbow and has better reviews...but what's the difference?
