Anyone have experience with Ronco chemical tanks (used as dip tanks)

[Frog]

There is a guy on Digitsmith selling these tanks at about thirty dollars more than here. http://www.tank-depot.com/productdetails.aspx?part=R-R240830A
These guys also sell ones by Chem Tech

I am wondering if polyppropylene is far better than polyethylene, and how important is the $30 lid? Would a hunk of wood with a small frame added do almost as well? I figure that any evaporation is water which can be cheaply replaced.

We don't use the lid here and just top up if need be. As for what poly does what your guess is as good
as mine. I don't think the chems we use are all that corrosive anywhoo. My neighbor at the old shop dipped
circuit boards (what many of these tanks are made for) and that stuff was gnar gnar.

Once you dip you never go back Andy.

Polyethylene is the material used for the original containers for the reclaim liquids, even the highly concentrated versions, I am not worried about effects of the chemicals nearly as much as the eventual brittleness that I see all containers of this material eventually suffer, albeit usually many years if not kept exposed to the sun.

Never bought a dip tank from the, but I really enjoy my Pocket Fisherman.   All dip tanks mad of some sort of plastic will warp and become brittle to a certain extent.  The top is completely optional.

possibly more than you want to know but then again you are a compendium of knowledge
hope it helps ..............warning the author is a Ph.D.

sonny beat me to it!  I was going to talk about the Showtime rotisserie.  Day late and a dollar short.

I bought one directly from tankdepot about 2.5 years ago for the 20x24 screens. I believe it is Polyethylene-still holding up. No lid, just put a nail in the wall above the tank and use it as a brace for a piece of wood to keep the screens submerged. When done I use a piece of cling-wrap to keep the chemicals from evaporating.
On my bigger dip tank I do use the lid as the opening is much larger.

Tank depot actually sells more than one brand, and two different materials.
They also sell a more expensive one from Chem Tech, and I believe that some of them are polypropylene rather than polyethylene.

Who am I kidding? I'm probably for sure going the cheap route if I pull the trigger on this lol! $96 and $35 shipping has to be the lowest price I've seen for this oversized, overpriced Tupperware.

It was a Ronco for $98, BTW.

Good to hear. A man after my own cheap heart!

What ya gonna put in it Andy?

[Frog]

I'll cross that bridge when I get to it. I am presently using some 4/1 CCI concentrate, but I have always used a 20-30/1 from either Kiwo or Autotype in the past.
I know that you have one from CCI that you like. Which is it?

I am figuring that they only get filled about 35-40% or less, right?  five screens displace approximately 58% of the volume
About 9 gallons is all that's going in, right?

GemZyne from CCI here. Never any luck with the all-in-wonder solutions.
$30 a gallon, makes 25 gallons or so.

We will ours up to nearly the top, you never know how many screens you'll
have in there and pulling one that the solution hasn't reached the top on is annoying.

[Frog]

Yeah, I'm over estimating how much stuff the frames will displace. I was initially calculating them as parallelepipeds (the equivalent of a cube that is not equal on each side) rather than the whatever the sixteen sided frame shape would be called lol!
So, how much does your solution rise when the tank has six or eight screens in there?

[ScreenFoo]

20x24x1.5 frame displaces about 125 cu. in., if I remember correctly, that's about a half gallon.

OK, I just looked it up to double check so I don't sound any dumber than normal--it is about a half gallon.
