herms return design

[Mark1964]

What do members herms returns look like ive seen all sorts of designs, shapes, and sizes just want to know what the more popular ones are like

 

[Vossy1]

Is this a duplicated question here :hmm:

 

[Mark1964]

No V not a duplicate one. Just want to know what people find the most popular

 

[Vossy1]

Might be worth starting a poll.

Stainless Aerator for me, as made by eskimobob

 

[Mark1964]

so it serves a dual purpose sparger and return

 

[Vossy1]

Yep :thumb:

EDIT...I suppose you could even use it as...errr...an aerator :lol: ...I've not tried that yet

 

[Mark1964]

might have to invest in one look alot simpler that a shed load of copper

 

[Vossy1]

eskimo makes them in various sizes as seen below

from this thread.

pm sent for a 15mm one :thumb:

I've got my name down against one too, however I don't think Eskimobob has time to make a batch at the moment so in the interim I'm getting one cloned in brass by a mate with access to the right tools.

Here's the fitting I have had made for the PT100 for the HX return, this shows wort in where the hosetail is, and wort out at the bottom where the brass compression is, this will go to the spreader/sparger. The PT100 is on the right, The housing is basically a lump of brass with a 1/2" BSP female thread at one end and an M8 hole at the other. I can trim it down a bit to get the probe in the flow.

I'll make a collar for the top of the thermos pot lid with a 15mm hole and one in the pot lid. The aerator will be able to be raised and lowered through the collar, which will have a screw to hold it at any height I want.

well that's the plan :geek: wil it work :hmm:

 

[Mark1964]

would your mate be willing to make another ill pay the going rate etc. Looks like your probe fitting will be fine :thumb:

No guarantee Mark, his company has clamped down on this kind of work so he tends to do it only to return a favour, he took the cylinder head off his disco in my barn at the weekend so he owes me one. It's all barter in Yorkshire, cash hasn't made it this far north yet I shall ask but don't hold your breath, he may want a goat or something in exchange. (he doesn't drink much so homebrew is out)

 

[beer taster]

I use a home made version of the stainless wort aerator - made from stainless nuts bolts and a washer :lol:

You can buy the plastic version from hope and grape - clicky

There's no guarantee that I will get one before the build is finished, depends on my mate finding the right window of opportunity, so I will be using the plastic one until then, nothing wrong with them, just a bit fragile, will be using one in the FV anyway. By then Eskimobob may be making another batch so I don't see it as a problem. Not sure what pipe size the plastic one takes but easy enough to make a temporary adapter.

I did get him to make 5 spacers for the front axle of my old Dexta tractor, the other four I gave away to tractor forum members who had similar issues as me. However that was before his company started throwing away all metal offcuts and clamping down on side work.

At the moment mine is just the vertical end of a piece of 15mm copper above a plastic plate that sits on top of the grain bed. I built a spinning arm but don't have space for it with the mash tun full.

You could be in luck Mark, my mate needs to do some more work on his disco so he drove it up here and into the barn before the snow came down. We rifled through my scrap brass box and he's gone away with enough to make two wort aerators/sparge/herms return doo dahs. Many thanks to Eskimobob for the dimensions :thumb:

Not sure how long it will take him but he's usually pretty rapid. Still no guarantee as he may make a cock-up or may not get opportunity to do it for various reasons but looking good :party:

How's the copper pipe wrestling going? :whistle:

 

[Mark1964]

All done for today thanks hope your mate can make them will be grand need to finish hex next week run out of bits just the soldering and a 10 mm elbow and a few washers to get now :thumb:

[Vossy1]

Simple really:

Length of silicon hose and a fishing net float, inspired by the Blichmann Autosparger
