I've recently upgraded my MLT to a 70 qt Coleman picnic cooler w/ manifold. Manifold is made from 1/2" cpvc. Was less than $15 for all of the parts and fits perfectly. The middle arm connects to the bulkhead fitting with a 1/2 Cu coupling. Here's the manifold:
Slits were cut with a Rockwell Sonicrafter about every 3/16" to 1/4". Dull as dishwater but not at all difficult. The problem I ran into, however, are small plastic slivers that are hanging on to the inside of the custs. I wrapped some sandpaper around a 3/8" dowel and than helped a little, but quite a bit of crud remains:
Any thoughts on how I might resolve this problem?
