Post subject:  sacrificial anode for plane body?
My plane body keeps rusting and it seems there's nothing I can do to stop it. Has anyone thought of attaching sacrificial anode to a plane body to protect it from rust?

Air is a very poor electrolyte, so not going to work, short of plating the entire tool.

For corrosion protection of metal planes and tool steel, the usual practice is to combine the use of barrier films (to prevent moisture and oxygen from reaching the surface) with reduction in available moisture (dehumidify)...in other words, wax your tools with a hard paste wax or apply a higher tech barrier coating such as BoeShield, and keep the dehumidifier running.


I tried paste wax, it made no difference.

Depends what's causing the rust. If it's high humidity in your shop, you could try this, which seems to be a paraffin wax/emulsion with aluminium (or maybe zinc) particles in it. I've used it and it works OK. The 250 ml tin I bought about 10 years ago is still half full. You don't need much.

If it's sweaty/acid hands, the above may help a bit or you could try this. Never used it, but maybe worth a try. Would be better than wearing gloves.

I got some 325 mesh spherical aluminum powder, would it help if I mixed that into regular paste wax?

Maybe these would work.http://www.leevalley.com/en/wood/page.a ... at=1,43326 or http://www.leevalley.com/en/wood/page.a ... at=1,43456 I have several Climagel dessicant bags in some of my storage cabinets. These are similar to the ones packed with electronics, except they are 3" x 3". I don't know if they are actually doing anything as my shop is climate controlled, but it doesn't hurt to have extra protection.

Alex, what an awesome solution. I wonder if that foam think could be used on metal surfaces like table saws, jointers, etc

These are pretty good at resisting rust:

I don't like those planes... its harder to adjust the planes and it just doesn't have the mass to cut correctly... Plus wood can warp and shift with changes in humidity too.

I put the larger plane in the drying room for now... I really can't afford to humidity control the shop at the moment, although I wish I could because the high humidity makes me feel like crap.

How about storing it in a plastic container with desiccant? A few silica gel pouches in a tupperware box would make a cheap and easy dry storage system.

D'oh....should have read Alex's post before my reply. Guess there's another genius reading this forum [clap]

I have used the VpCI-126 bags from Lee Valley for my planes and chisels with no problems. The current batch is near its 2 year use by date.

A good evaluation of corrosion inhibiting products available for A2 steel and Cast Iron was published by Fine Woodworking in their July/August #212 issue. Their top performers for both A2 steel and Cast Iron were CRC Industrial 3-36 Multipurpose Lubricant and Corrosion Inhibitor http://crcindustries.com/auto/?s=03005, LPS3 Corrosion Inhibitor http://www.lpslabs.com/product_pg/corrosion_pg/LPS3.html and regular WD-40. The LPS3 was dinged for leaving a slight waxy/oily film on the tool which transferred to the wood if not wiped well before use. I picked up a can of the CRC 3-36 at a local auto parts store for $6.00. So far no rust.

What surprised me in the results was poor performance of most of the products sold for rust prevention like Camelia Oil, different waxes, WD-40 Longterm Corrosion Inhibitor, Boeshield T9, 3M Rust Fighter, etc. Regular WD-40 did a much better job than any of the expensive products in this test.

I read this article and to my eyes WD-40 looks equal to the CRC product. I have been using WD-40 for over thirty years and will continue to do so. I also like it's smell compared to many other oil products.

I do not know what is in my shop that causes stuff to rust sooner than usual. I had a small fire in the shop due to a stupid mistake and the smoke seem to have caused rusting (the smoke was from burning plastic and pyrotechnic compositions that may contain acids), but ever since then when I cleaned the rust off, it just comes right back. I tried WD-40 and it didn't really do much either. Now I've tried baking soda wash to hopefully neutralize any acids but only time will tell...

A phosphate surface treatment would help a lot. You can do a crude iron phosphate coating by soaking the cleaned plane body in dilute phosphoric acid for a few minutes, then oven dry it, and apply an oil. A strong phosphoric acid solution will remove rust. Here in the States, Jasco Metal Etch is a readily available product--just phosphoric acid, water, and some detergent to remove oils.

If you can find a metal painting operation, they probably use an iron phosphate spray pretreatment. Maybe they'd agree to run your planes through that. Even better would be a zinc phosphate pretreatment.

If anyone is restoring old handguns and rifles in Taiwan, they may know where you can buy chemicals for "Parkerizing". That would give you a particularly durable phosphate finish (usually manganese phosphate, I think).

Nobody does anything with guns in Taiwan, they're considered condemned contraband and possession of those is a very serious crime. It's a bit like Japan actually.

However I can get the chemicals, I don't know about parkerazations.

The burning plastic very likely released chlorine (e.g. from PVC [polyvinyl chloride] or numerous other plastics). Chlorine is extraordinarily corrosive (DAMHIKT). If you ever find a way to "neutralise" the chlorine, please let us all know! Maybe some of our resident inorganic chemists can help.

Yea, and the burning pyro comp had chlorine donor in it that forms HCl when it burns.... I don't know I just use a base of some kind like baking soda...

-What Eric Reid said. 'Ospho' is a good otc product
but may not be available where you are.
