6" bubbler build

Postby j0sh2008 » Fri Nov 29, 2019 6:10 pm

Hey all :greetings-waveyellow:

I picked up some 6" and some 8" at the scrap yard the other day. So Ive decided to build a new 6" bubbler. I'm thinking of making a 8" inline thumper on the bottom also. If I can work out how to make it.

What volume should the thumper be? Also I'm thinking a 500mm 3" PC but I'm not sure on the RC any ideas what a good size would be ? 300mm?

Cheers

Good score, I wouldn’t go a 3” Rc though, looks like you’ve got enough 6” for the whole rig, inc the rc

Do you mean PC?

I wouldn't go 300 mm on the RC, probably no more than 150mm, but it'll also depend on what size and how many internals you put in it.

My bad. Yeah I mean 6" RC and 3" PC.

So 150mm RC and 500mm PC would be alright?

I would put baffles in the RC and PC, it will help cooling efficiency, which you will need with that much vapour through it.
Maybe keep the internal tube to 1/2" or 5/8",
3/4" is a bit big and needs a bit of mesh poked into it to work properly.

:text-+1: but I think baffles in a PC are a waste of effort.

What are baffles ?

Also would there be any benefits of having dual water inputs/outputs? In the RC. :handgestures-thumbupleft:

Baffles are partial plates inside the RC that force the water to change direction and therefore have a longer journey through the RC. They are parallel to the end plates and the input is opposite to the open end of the baffle plate. If you go for multiple baffle plates each plate will have its open end opposite to the previous plate. Checkout woodduck's RC on his mother duck build, you can see his RC plates in the photos on this post the middle plate has a section missing from it, it's the open end.

My Rc is way too big on my 6", it takes forever to adjust and only needs a tiny amount of water running though it so is touchy as hell. When I get my ass back in the shed one day I will pull it out and halve it's length I reckon. I think the sheer volume of water in such a big rc is too much of a heat sink.

What size RC would you re make it to?

Probably 150mm might even try 100mm. I like responsive rc's and I don't need to hold full reflux for long.
