Hi-
I am attempting to build a home made hop stopper, and was wondering if anyone had any pointers. I am trying to keep the internal diameter of al lines feeding into my pump at 1/2" or larger, so buying a hopstopper (which I would be TOTALLY worth it to me if it had a 1/2" internal diameter) was out. As such, I need to build one. I have read of some people having problems with the very fine mesh, and some people thought 30x30 was too coarse, so I am using 35x35 mesh and 5/8 inch OD copper tubing. I also want to minimize any clogging issues as much as possible, and think I can make it less likely by bending the copper into a spiral pattern and cutting small grooves on the underside of the copper spiral. The more surface area of inlets the lower pressure on each one, and I think the less chance of getting clogged.
Here is an image of what i am proposing. I have a few questions, though.
1. Should I let the distal end of the tube be open? I am worried I might lose suction sooner if I do that.
2. How hard is it to bend this stuff? The inner part of the spiral will need to be bent into a pretty tight radius of curvature
3. Do I have to leave space off the bottom between my copper spiral and the bottom of the stainless kettle? If I rest it right on the bottom will it cause scorching issues during the boil? What about the steel mesh-- if it touches the bottom of the kettle will it cause scorching of the wort?
4. For anybody who has built one of these before- are there any design flaws that i am not considering?
5. Even though the 35x35 mess seems pretty stiff, do I need to tent it up like a pyramid in order to avoid clogging?
Thanks for any help!
