Hop Spider Build Questions

StrmStlkr · 01-09-2011, 09:09 PM

I am attempting to make a hop spider but I coudln't find any CPVC reducers. All my local Home Depot and Lowes had was smaller CPVC parts but no reducers. I found this 4" to 3" galvanized reducer and decided to use this instead. I cut the bottom of the reducer (3" side) into "fins" in hopes that that will help with keeping the paint strainer sack open for better hop utilization. Since I have cut these fins I am afraid that they will eventually start tearing up the paint strainer bags so was thinking about wrapping them in tape of some sort to keep them from being sharp.

Will this work? I am afraid that the tape may leach something into the sack after sitting over a boiling pot for over an hour. What do you guys think or suggest? If you think tape will be fine, what kind? Teflon, electrical, duct?

I have attached a picture below to cut down on any confustion of where I am having issues.

As a side question for after I get past this small hurdle, do any of you find that the 5 gallon paint strainer bags are two large for your pots? I have a 40qt pot and am only doing 5 gallon batches and the 5 gallon paint strainer bags are two large for my pot. It will easily touch the bottom which I figure is a no-no. I feel that a 1 gallon size will be two small and I cut one of my 5 gallons ones in half but the opening is now way to large to easily secure onto the bottom of the hop spider due to the elastic part being cut off. What do some of you guys around here do to overcome this?

Thanks for all of your help.

I use 1 gallon bags and have never come close to over loading them. I feel like I get great utilization. Mine is pretty simple and straight forward:

I will have to see if I can find any one gallon bags and try those. Any thoughts on using some sort of tape to cover the sharp edges?

I was going to wrap the end of an all copper heat stick with this. Heat resistant to 500 degrees according to their website. Not sure if you can make it work with the sharp edges or not, though.

Good luck.

My only concern with using tapes is that something might leach out of them when sitting up over a boiling pot for over an hour. Do you think this concern is valid or me just being paranoid?

How about rolling the corners around a small shaft like a sardine can gets opened with a key?

I'd be concerned with galvanized metal that close to my brew. I know direct heat/flames on galvanized causes toxic fumes, and that it's a no-no for direct contact with food (especially acidic things like wort), but I'm not sure if a little condensation dripping in would harm anything or not. Personally I'd rather not take the chance, but YMMV.

@Hannable1975, you may want to consider flipping your coupler upside down. The hose clamp may seem super tight, but the plastic and metal expand and contract at different rates with the exposure to heat from the boil, and it can come loose. A bag coming off with a huge hop bill inside can be a real mess. By flipping it upside down, the flange keeps everything in place.

I believe the link I posted has silicone tape. I was going to use it for a heatstick handle. Handles heat up to 500 degrees. No adhesives.

Am I wrongcaboutvits safety?

i would say to fix the sharp edges is take some clear vinyl tubing like 1/4" inch or smaller slice it straight down one side and put over the edges.

Well, I figured it out and the 1 gallon seems to be the trick. I am now worried about the point you brought up. I am too a little worried about using galvanized metal over a boiling pot of acidic wort.

Where did everyone find their CPVC reducers at? My Lowes and HD didn't have any CPVC material in the larger sizes (2", 3" or 4").
