Greenie Bench Tubes - Diameter?

[beeg]

Thanks MickyD. Last time a couple months ago I did knot understand how to set it up. But this time after reading it, I GOT IT. You want several rods wired together for the positive connection, then the negative connection is attached to the the piece being cleaned. :)

Now the idea of using PVC is interesting. Maybe an outer pvc pipe and an inner to reduce volumn and fill with Evapo-rust and let soak. Sounds like a lazy man solution.

Nick's potato video (http://www.youtube.com/watch?v=qYgnHDB3VNI). I personally think the "potato" method is a not worth the effort for heavy rust.
I like your idea bucksaw. If you could seal off the bench tube ID with something (hey, maybe stick a potato in it....) and use a 2" ID PVC tube (area 1) and put the 53 inch long 1.875" OD bench tube into it (area 2), it would take about 12 fluid oz of liquid to fill the void. For all you math heads out there, (Area 1 minus Area 2) x Length = Volume

Sorry for getting techy but I just had to know the answer. Since I just HAD to figure it out, I just had to share the answer :-). After the day I had stripping paint off my SS, I had to make sure that I didn't mess up too many brain cells!!!!

Don't use rods. Instead, use pieces of sheet metal that fit tightly around the inside of the container. It has much more surface area and it not only cleans faster but also, you don't have to clean off the junk that gets deposited on it so often. With the rods having such a small surface area, they start to loose thier ability to attrack since they get VERY gunked up. Look at the sheet metal I use in my container. It's in my post :

Have you seen Nick's video on how he gets rid of the rust on the bench tubes the lazy mans way? He uses a potato in a PVC pipe filled with H2O. I just tried to find the video but couldn't. I'll look again or if someone knows where it is, post the link.
Here is the 8 minute video of Nick's potato cleaning.
