[PSUBS-MAILIST] Scrubber

[hank pronk via Personal_Submersibles]

 Brian,That looks fantastic!  great job, but do as Alec says.  bolt the middle screen to the bottom, so the lid comes off then cut a foam piece to go between the lid and media.It will work like a charm.Hank

 But you need something to tamp the Sofnolime down as it settles. My old scrubber used a layer of foam under the lid. My new one has a cylindrical lid that slides between the two cylinders and is kept tight by bungee cords. Emile's scrubber as I recall uses springs. You just need something that will compress the Sofnolime to prevent the formation of an empty gap. If there is a gap between the top of the Sofnolime and the bottom of the lid, air will follow the path of least resistance and not get scrubbed.

Alec,    I think what I'm going to do is make a hole ( or holes) in the top lid where I can pour the Sofnolime in through a funnel.  I'm waiting to get the Sofnolime to see how big of a funnel I would need.  Then I can fill is all the way up.  When I'm done for the day I would take it apart and dump out the spent medium.  I'll fit a cork in the filling hole. Brian

Brian, it looks great and the creativity of using a pasta strainer and patio heater is vintage PSUBS. But how do you fill it? Normally the inside cylinder would be attached to the bottom of the outside cylinder, leaving a space between the two for you to pour in the granules. If the inside cylinder is attached to the lid, you would need to squish the granules out of the way when pushing the inside cylinder in. I think you might find it a bit more convenient to just unscrew the inside cylinder from the lid and bolt it to the bottom instead. You can also make yourself an annular sponge to put between the top of the granules and the lid. They will settle, and there should be no air gap between granules and lid. 
Best,Alec

All,                   Got my scrubber ready to go!   Here are some pics.  Outside is made from the screen that goes on those outdoor patio heaters, inside is a pasta strainer.  Blower is the a 7.5W 12 volt and the cover is made from Starboard.  Brian
