STANLEY BENCH PLANE RESTORATION

More information available on my woodworking blog & podcast The Folding Rule Show
Step #1 – Cleaning & Rust Removal
I have been inspired by a number of resources to start using my hand planes and start on the slippery slope of a hand plane collection. Not the least of whom has been Wayne, our own Lumberjocks plane guru. Of course I have also explored a number of websites including our good friend Phil on the other side of the pond and Matt from Matt’s Basement Workshop.
Another great resource is Patrick's Blood and Gore
Most importantly I have come to realize I need these planes to achieve a higher degree of fit and finish. Plus I like the quite sounds of hand tools and the feel of a thin shaving of wood peeling out of the plane mouth. So the focus of this entry will be an old, but not so valuable, Stanley bench plane that has lived in my carpenter’s box for perhaps 25 years. I used and abused this plane for coarse fitting work on decks and fences. I also used it to hand plane a bunch of clear vertical grain construction redwood for a bed that I made for my wife and I almost 25 years ago.
I am hoping I can revive this fellow to take a place on my bench for future work building furniture and cabinets. Along with my small Stanley block plane, these will be the nucleus of my plane collection.
Today I disassembled the plane and started to experiment with electrolytic rust removal on the plane iron and chip breaker. I plan on replacing these with a Hock set in the near future. The reason I am spending time cleaning these is because I am going to use them in a multi-sized dowel-cutting jig. Also, I want to see how well this process works before dunking my plane body in the bucket!
UPDATE: Thanks to Wayne here is a great link to check out for HOCK BLADES
UPDATE: Thanks to Scopemonkey for noticing I got the polarity reversed on the first posting. Below is an updated diagram with the correct polarity. Thanks Scopemonkey!
The cool thing about this project is that I already had everything in the shop!
Use a brass brush and a 3M grey abrasive pad for final cleaning.
Some residual stubborn stains were removed with a bath in glycolic acid. I used Kaboom Shower, Tub & Tile Cleaner. After the acid bath I rinsed the parts in fresh water and ran them in the electrolytic solution for 15 minutes to neutralize the acid followed by a second rinse in plain water.
After completing the de-rusting and cleaning process all parts were treated immediately with BoeShield T-9 which is available at the Lumberjock Store. WD-40 would be a good alternative to BoeShield T-9.

UDATE: Thanks to Wayne, our own Lumberjocks plane guru, make sure you will not alter the intrinsic value of your plane or other tools by this type of cleaning process, i.e. some planes have igh collector vaule and should be left as is with age patina.
MATERIALS LIST
• 5 gal plastic bucket
• rebar pins for anode grid
• copper wire
• wire nuts
• alligator clips
• Arm & Hammer Washing Soda (sodium carbonate)
• 6/12 volt battery charger

• brass brush
• 3M grey abrasive pad
• WD-40
• BoeShield T-9
BUCKET PREPARATION
• Drill holes near edge for twisted wire loops
• Secure rebar with twisted wire
• Connect rebar anode grid with copper wire & wire nuts
POLARITY IS CRITICAL!
The BLACK (negative) lead is connected to the part being cleaned
The RED (positive) lead is connected to the rebar anode grid

SAFETY CONSIDERATIONS
Before starting, review the Material Data Safety Sheets (MSDS) for the recommended products
Use common sense – if it doesn’t feel right don’t do it
The gases generated are oxygen & hydrogen
Do this process in a well-ventilated area away from sparks or open flame
Wear gloves and safety goggles / glasses
The electrolyte solution is mildly alkaline and could irritate your skin and eyes
Wash any splayed solution off your skin with plenty of fresh water
Despite some recommendations, DO NOT use stainless steel for the electrodes as the results produce a toxic solution containing hexavalent chromate. Hexavalent chromate is a poisonous and hazardous material that requires special handling and disposal.

Great info. I’ve been wanting to try electrolytic rust removal but not gotten around to it. Any thoughts about getting a hock blade and chipbreaker?

I have a couple of old Bedrock planes that belonged to my great granfather, and I’ve been wanting to clean them up. I can’t wait to try this out. I also can’t wait to see the look on my neighbor’s face when I’m standing in the driveway looking over a bucket with a battery charger and wires running to it while wearing rubber gloves and safety goggles!

This worked out really well and I was pleased with the results. The plane body is next in the tank followed by lapping and a new plane iron chip breaker set. I guess the next project will be a shooting board thanks to you guys!

I was wondering about that, Wayne. I’m am very unfamiliar with planes, but I’ll get the numbers off of them and let you know. I may even take some pictures if I get a chance. They are in bad shape. Apparently my great granfather and grandfather really put some hard miles on them. I ran across them last summer when I found my grandfather’s old wooden tool chest. I was so excited to find them, but nobody could understand since they were just “junk”. Oh well… one man’s trash…...

Good advice as always! Just for clarity, I cleaned this plane because it has no other value than just a tool I wanted to tune-up. Obviously some tools should be left in thier original state so you don’t alter value.

Thanks David.
I would agree this plane is a good candidate for restoration. There are lots of them in service. But with some planes selling for in the multiple hundreds to thousands of dollars, it pay to determine if the plane has any sigificant collector’s value. Ebay is a good way to do it.
Check out what Bedrocks, Stanley #1s and #2s sell for. It may open folks eyes.

David, Thanks for the great information. I have just recently acquired a couple of older hand saws that were my grandfathers. I am wondering now if this may be the way to look in to cleaning them of some the rust they have accumulated.
any idea if the trick would work with them as well?
Thanks again

This will work on your handsaws. One site I saw did one end at a time. You could also just find a larger container or tank to fit the blade. One word of caution is to make sure you do not de-value the saws by cleaning and removing patina. Send Wayne a PM about this as he is a great resource in this area. In summery the electrolytic process will work for any iron or steel tool. Let me know how it goes!

Excellent website link from Wayne (as I would expect!).
Two observations. (1) The anode he is using is somewhat limiting as the electrolytic process is “line-of-sight” so what I would reccommend is a couple of long pieces of rebar connected by wire set-up with one bar down each side of the tub and perhaps one down the center with the saw suspended in the solution above the anodes (rebar). (2) The tub to look for for de-rusting a saw is one of those flat wrapping paper storage bins.
Good Luck!

Help! I’ve been all over town…granted, Wausau WI is kinda the shopping armpit of Wisconsin, and can’t find washing soda. Short of going online and spending $6.00 to ship a box here, where can I find the stuff. I’ve got a Stanley plane thats crying (rusty tears) for the treatment.
I’ve tried a hardware store, grocery store and Target. Have I missed the obvious? Is it at my local Wal-Mart?

I also had a bit of trouble locating Washing Soda. I finally found it a a local grocery store (WinCo) in the laundry supply section. I did a quick search online and found a conversation string regarding the same difficulty – excerpt posted below:
“Go to the Arm and Hammer Website, they have a product finder feature where you enter the zip code and they list stores near you that carry the product . . . “
Have you tried the Arm & Hammer website zip coade locator?
I feel bad you are having difficulty . . . hopefully another LJ that is locat to you might give some additional ideas. I did read on another website that some one used A & H Baking Soda ( a different compound ) and was successful – I just don’t have any experience other that with the washing soda.

Thanks for the info. Oxy-Clean can also be used (sodium carbonate and sodium percarbonate) and is widely available. My local supermarket didn’t carry the A&H product. I just wanted to point out that the cartoon graphic has the polarity reversed.

David,
In using this method does it also remove the japaning from the plane? I just got a Stanley 140 skew plane that I want to try this on. The japaning is in good shape but the body is quite rusty on the sides and sole.

I’ve read on other blogs about electrolytic rust removal that the japanning is not affected. I would use caution as I bet it depends what the actual finish really is – my plane had a blue jappaning which was firmly intact. After removing all the rust the jappaning had lifted in a few areas. This did not bother me as I was intending to re-apply a finish (preferably black). Also, as Wayne mentioned, make sure your plane is not a collector plane with intrinsic value. Cleaning a collector plane may alter it’s value negatively.
Let me know how it goes – I am curious!
Cheers,
David

Thanks, David! I have a plane that is screaming for this treatment! No collector’s edition, just an Ebay special I want to restore to service. I found a link to the Arm and Hammer Washing Soda: Here it is.
It cost around 9.55, delivered to my door. I might have found it somewhere else, but i figure my time is worth the 4.80 delivery fee.
I got a few others that may get dunked, too. Most have rust that is creeping up in hard to get to places.
God Bless,
Hawg

A couple of things I have picked up in my research is that the japanning is removed only if there is rust beneath the japanning. I have not been able to verify that, but I do have an extremely rusty (with some possible pitting) Stanley Bedrock 603 (which might I gloat and say I picked up for $15) which might be able shed light on this, but I haven’t cleaned the rust dust off of it to tell if there is any japanning to begin with.
By the way, do we have any electrochemists that can explain to me how to create a home nickel-plating rig? If so, ping me with a PM.

This process is pretty cool. Its cheap to set up and you can restore all kinds of tools that would otherwise be lost. Now those tools that you would have passed over at the garage sale can be picked up for CHEAP. Who is going to pay for a rusted piece of “junk”? HEE HEE HEEE we can take em home and zap em and presto brand new. I had to buy a charger to do this. I went to harbor freight and tried this one it didn’t work. I returned it and got this one and holy cow it worked. That thing bubbled like crazy! You could see the gas vapor coming out of the 5 gallon bucket. I set up a fan to blow it our of the garage. Coooool!

David,
I’ve been trying this process on my own and I’m amazed at how quickly the parts rerust after taking them out (resut is appearing within 60 seconds). You say you spray them with t-9. Do you do that immediately after they come out (while still wet?) I’m just trying to figure out how this works. Also, does the parkerizing only work when you use hot water or can you just use room temperature water? Thanks for any advice you can give!

I apply either WD-40 or T-9 after pulling out of warm electrolyte solution and drying off with a clean shop towel. Warm water works best for the modified parkerizing. Looking forward to photos of what you rescue from the rust heap!

This is what I use all the time.I have known of civil war collector buffs that use this method to clean up metal artifacts they find in my area. There are faster ways and other stuff like oxyclean you can use. I use a different power supply and a similar setup. I reworked a lot of my tools and a extra benefit is a lot of times it loosens bolts and screws. My lathe was so rusted nothing turned. I did this to some of the parts and it got them broke free with no effort at all. The bolts were like they were just tightened. Don’t use this process with anything chrome or electroplated. I restored my old truck and used the process on the metal frame that holds my vent window glass. I left the knob that was chrome plated on. It started to make the chrome release from the knob. I had to use a different frame and I was glad I had an extra. Just be safe using it since it deal with electricity and water.

I agree it is a safe procedure. I have used it for years and now have a more powerful supply I use that works fast for me. I always remind people to be safe with it. I put my supply above the tank and have it away from the tub I use. That way if I accidently spill the tub it won’t go into the supply. I also have the supply away from the tank so if it falls it won’t go into the tub. Its a quick and easy way to clean for me. Other than electricity it doesn’t cost me anything. I have a box of soda I used I bought years ago.
