Rust and restoration

[novatech]

I like to buy old equipment and restore it back to working condition. I just bought an old New Idea drop seeder to plant some bluestem. Well the first thing I have to do is clean it and remove the rust. I thought this would be a good time to pass along the method I have been using fore quite some time now.

I will be putting the entire planter in a large tub made from plywood lined with poly plastic. 14 foot X 5 foot
Not till drill--around 24 thousand?
Old seeder and old harrows $20.00 plus paint and a lot of fun.

Actually using plywood concrete forms from a past job. If it blows apart then at least I'll get my driveway cleaned.

What's the volume of baking soda to water?

1 tablespoon per gallon.

Thanks. If he said it I didn;t hear it

I use something similar for cleaning copper fouled barrels except it's copper plating the other rod. Takes some pretty evil smelling chemicals to work

Is sodium carbonate used or sodium bicarbonate? Baking soda is bicarbonate. Sodium carbonate is very alkaline.

I use the laundry detergent, Don,t have a clue what it is. I have also used lye. So maybe what they are looking for is a high alkaline solution? What ever it is they call it an electrolyte.

I would put it in the box before i filled it up with water. Then screw some braces across the top to help hold it all together. I would love to see some pics of this setup.

If I do it I will get some pics. I agree it will need some bracing across the top. Th problem is I'm going to nee a larger power source. My welder is gasoline so running it that long is out of the question. If I go to the junk yard I may be able to find enough heavy duty 12 or 24 volt power supplies to do the job. Battery chargers I'm afraid would burn up.
This didn't seem like such a big deal in my head but as usual a project this large may take a lot more than what I have available.

If you figure in the cost of material and electricity it may require you might be better off having it blasted.

The power supplies are cheap at the junkyard since there is very little salvage value, about 5 bucks is all I have ever paid. The laundry detergent is cheap. The electric bill is also cause I never look at it. That's my wife's department so I don,t have to figure it into the cost. ;-) Actually on the sheet metal I will probably use ospho (spelling is wrong , but it is a chemical treatment.) That leaves me with the parts I think will already fit into what I have.
If you have never tried it you should. It is especially good on things that cannot be gotten to with a brush or sand blasting. Old tools like rusted up pipe wrenches, pliers, etc. come out great. The best use is on machine tools that you cannot leave the wire brush scratches or sandblast pits on.
There is a guy on youtube that shows how to do inside a gas tank.

Sounds like about 80% of the projects I come up with here at home. :lol:
