Simple hop strainer assembly
 
2 Attachment(s)

(chuckger's build)

I've purchased parts to build a hop strainer, a lot like the one in this picture (and the one in the HBT wiki). I realize this is a relatively simple assembly, but to a new brewer it could seem fancy and complicated at first glance. So, I am going to take photos and describe what I'm doing as I build my own version of this.

I bought:

(1) 4 inch PVC coupling, $1.13
(1) 3-5 inch hose clamp, $1.85
(3) 12 inch length of 1/4-20 threaded rod, $0.98
(2) 8-pack of nuts, $0.98
(1) 4-pack of wingnuts, $0.98
Total: $8.86 + tax

I already have a strainer bag whose opening is about 4.5" diameter that will work perfectly for this, shown in the attached photo. I think it cost about $3.

Both of my drill's batteries are dead, so I've been stalled for an hour or so while I wait for one of them to charge. I'll be drilling soon and should have finished pics up within a couple of hours.

I drilled 3 1/4" holes in the PVC fitting and installed the threaded rods using two nuts per rod. After that, I tested the fit on my 15 gallon kettle. I spun a wingnut onto the end of each rod and used that to center everything.

First obvious discovery is that I am going to need to get some fender washers involved with the wingnuts, as well as an intermediate locknut on each rod to restrict the washer's range of travel.

My other observation is that if the top of the PVC is level with the top of the kettle, I think the bottom of the bag will just barely dip below the surface of a 5 gallon boil. I think if I drill the 1/4" holes in the PVC to more like 3/8", the threaded rod could angle upward at a decent angle, lowering the assembly further into the kettle. I could replace the nuts that hold the rods to the PVC with nylocks (getting some fender washers involved here, too) and adjust the spacing between them to adjust how high the assembly rides within the kettle.

I did a little bit of work on it tonight. I added fender washers at each of the wingnuts, which are then held against the wingnuts with ordinary nuts. I also drilled the holes out to 5/16" and replaced the inside nut with a locknut. The rim of the PVC rests 1.5 inches below the kettle top, and the bottom of the strainer bag is 5 inches above the bottom. I will give it a try when I'm brewing tomorrow.

I tightened up the rods to bring the PVC up to the kettle's top and make everything rigid, then attached a much larger strainer bag. This was a bit too high for when the boil got down to 5 gallons, but got me through the brew session. I think I can slide the bag and the clamp down enough to get it better submerged next time.
