[TheForge] Chemical Questions ?

[Terry L. Ridder]

hello;

i will answer the part concerning large objects.
for large objects i use a 500 gallon rubbermaid 
lifestock tank. i normally use two boxes of washing
soda per tank. for anode i use  several different
items depending on what the object being de-rusted
is shaped like.

0. coffee can lids wired together to form a sheet of
anode.
1. fine mesh stainless steel screen. good but plugs up
   in a short amount of time.
2. large sections of cut up 250 gallon heating oil tanks.
   heavy to move around, mainly for large flat pieces.
3. stainless steel electric fence wire used to make chain
   mail. nothing fancy just a large piece of 1/2" diameter
   ring chain mail. this works extremely well for nearly
   any shaped object. i am able to contour it is most shapes.

small items are easy.

large coffee can with stainless steel electric fence wire
attached. immerse coffee can in tank. suspend  small object
from steel dowel again using stainless steel electric fence
wire to attach to small object. hook up battery charger or
12 volt power supply and watch the bubbles.

i have used 100lbs propane cylinders with the top cut off
for some parts. in this case the cylinder is the anode. i
only use cylinders which are not usable for other purposes.
