These ones look like they have a finer grain size, I might buy one to have a look at it, they're cheap enough. I would probably drill out the plastic pipe and bond in a larger Brass one so that there's less restriction. I'd want to see how they pass water to make sure the flow was adequate. I doubt if it's a problem if you use a long one. I thought these would be ideal for sitting in the bottom of the side tanks on 1501.

The problem with these could be the flow rate, they are made to pass air into water not the other way round. I have a spare one so will do some tests. Ideally they also need to be removeable so you can reverse flush them to clean them.

Hi Jim Mike and Roger I have made a in Lin adapter to use Iwata in line gravity feed paint filters. The link is. www.anest-iwata.com.au/products/spraygunfilter-strainers/sel.3They are about 25mm long and 8-10mm dia. Jim I will send a pic to you and you might be able to post the pic. The filtets will be under my side tanks before injectors or boiler. David |

I have a small one in my zorb fish tank and it gets contaminated pretty quickly too. I have to change it annually, but then again a tender wont be full of fish crap........LOL Maybe those filters that are used on washing machine inlet feeds might do ? |

I've looked at the link and the filters certainly look interesting. Jim |

It looks very interesting and could possibly be adapted to fit the filling point as suggested by Adam. Jim  |

I did a quick test on the air stone that I have and you can pull water through it but it requires a bit of a suck (scientific term 😊) It will then symphony (syphon, bloody spell checker) through the filter after that. The one that I have is ball shaped and about 1inch across. The bar type that Roger mentions may allow more water through. May well be worth further experimentation by those interested but I have had a go at a mesh filter made from a plumbing coupling and intend to experiment further with that. I will post some photos when I fire up my pc.

I've just ordered a couple of these 6" ones to see if the restriction is an issue. I tend to turn the argument on these things round the other way and ask myself if I was trying to restrict the flow, would this be a good way to do it? My guess is that with something as long as this, you only need a tiny flow through each square millimetre to make up a significant flow for the whole thing. I don't see that it's necessary to remove it, you could always reverse the flow or use an air line if it was choked, but you'd need an awful lot of material to cover the surface of something that big. |

This is mark I of the filter I am working on at the moment, the main body is a straight 28mm plumbing coupling care of B&Q which is milled out to give the filter cage. The ends are just brass turnings and the pipe is bent over inside to pick up from the bottom. At the moment it is all soldered together but I am not happy soldering the mesh inside. this needs to be soldered to the cage to stop water going round the filter mesh and defeating the whole point of the operation. Mark II may well be glued together and the mesh a little finer. I original idea came from a YouTube video by no23mk2, I just made it a bit bigger as I have room in the tender.

Jim,
I am just setting off from work so when in the workshop I will try remember to get a photo for you!

Thanks for the photos Adam. I must say that looks to be a very elegant solution in that it filters the water, stops foreign matter entering the water tank such as particles of coal and is easily removed for cleaning.  Jim |

We are starting to get two distinct types of filtration here. One to filter the water as it is added to the tank and one to filter any stray particles that have got into the tank. I can feel the old belt and braces getting a good stretching again.

If you were really going all scale on the tender then the filter boxes serve a great place to add.....filters.....just saying (no advertising here!!!)

As a unit the rear of the tender is now complete with the lamp irons made and in place. I still have the ladder to make but I'll leave that for the time being and get on with drilling and fitting the rivets on the tender sides. With that job done I can then reassemble the tender and then make a start on the remaining fittings needed to complete the job. These are two views of the tenders rear. I couldn't help myself and just had to add a marker disc for the second photo.    Jim |

Those lamp irons are particularly good, Jim, lovely job.

Thanks Steve, they're fiddly things as you know and there isn't much detail given in terms of dimensions etc so I went back to photos.

Hi Jim, I currently have a 3.5 inch Britannia that seems to have had very little use ie stuck regulator now freed off, however the off side vale appears stuck and not wanting to force it have you any ideas as to how to free it apart from a strip down .
James.
