Hello everyone in Megland,

I am starting this thread after failing to find the requested information through a search. Sorry if the info was already posted elsewhere.

Back on 23 December 2008 Rob Dobson posted: “You need two spacers though if you want to use a standard size scrubber.” Referring to using a "standard sized" scrubber in a tall can. I am not sure if he was referring to a standard sized Axial or Radial.

Link to that thread:

A big thanks to Rob and Deep Baloo for the tip. That gem of information got me thinking.,,

Question A:
I want to us an axial scrubber in a tall can. Is this possible and can it be achieved using the following:

1. Standard Axial Scrubber (which I currently do not have and so cannot test)
2. The spacer that comes stock with an axial scrubber for a standard sized can (also don't have)
3. The spacer that comes with a radial scrubber for a tall can (the height of this spacer is 8.5cm / 3 and a quarter inches) (now these I do have)

Question B: what is height of the spacer that comes with a standard axial scrubber for a standard can?

Question C: does anyone strongly advise against diving this setup for shallow easy dives? If so, then please elaborate.

Thanks allot in advance for your answers.

Al hi,

i reckon if you have a single spacer and a standard axial scrubber, you can use something like layers of any sort of material, as long as it is flat, so you can build the difference. as long as there will be the normal spacer, then the air will travel through the axial scrubber.

you can cut layers of marine wood, (just a thought and i hope i dont get bormbarded with this one now) so you can actually fill the gap. that one is good and solid and i dont think it would be affected by moisture.

i am wondering about the emptiness inside the can and how it would affect your balance underwater. maybe you can try? let me know how it goes.

Thanks. i would apreciate your comments on pm please.

Thanks for the lightning quick response. I've just about finished making the marine-wood spacer in my shop and am kitting up for an 800 meter dive.

Just kidding. I like that you are thinking this through with me. I am surprised when people get flamed online for brainstorming. Afterall this is a forum for discussion supposedly populated by people with an urge to explore new things and places.

I am responding to your PM now.

Thanks Al. well, exchanging ideas is a good thing. it doesnt matter if someone else might have asked the same thing before. if it was like that, then noone should have been talking, but just reading in here.

as for your idea, i find it very interesting. if you have some free time, then you might as well, explore it. just make sure that the can sits fine and it doesnt have any space, (to allow the scrubber catridge to go up and down) as i am thinking it might create some problems. but i really think that it can be done.

Hi,

Firstly, it is possible to use the standard 5lb axial scrubber and/or the radial 5lb scrubber in the tall can. You just need two spacers as you already know.

Im assuming you have the 8lb radial scrubber?? The spacer that came with this for use in the tall can is the same as what comes with the 5lb scrubbers for use in the standard can. IE, you just need something to put in the bottom of the can that is the same height as the spacer you already have, AND the spacer. I was lucky enough to have 2 spacers for use in mine, but you can use whatever in the bottom - a length of drainpipe that was wide enough to support the spacer and scrubber for example.

I used this setup many times if I was just planning a single relatively shallow simple dive. It worked well, and I couldnt notice any difference with trim.

Good luck, and let us know what you end up using.

Cheers,

Pete

Maybe walk down to the local department store and purchase a plastic/composite cutting board or two? They come in various thicknesses. Durable as can be and the material should be stable under the conditions.

I do like the drainpipe suggestion though. Get a diameter that is close. Cut it to the right height. The slice it down the side and take a piece out of it so that it fits inside, yet expands against the sides of the can. Place a spacer on top of it. It won't move accidentally and can be removed when needed.

Thanks to all of the above, that's exactly the news I was hoping to hear.
