BATH TIME
Just want to remove some of the sludge before I proceed. Using hot water and mild detergent with a soft brush. It leaves the parts a bit greasy, which is ok for now, it seems to protect from rust. Am I on the right track?
Sunday afternoon project:
This one required the use of a hard hammer, but I think it turned out ok. Serviceable if not pretty. Check the before and after pics.
Maine, in the next steps which method are you going to try? Electrolysis? Evapo-Rus? wire brush? etc? In any case removing the caked up grease and sludge is always helpful for the next step.
Maine: you can even just wire wheel off the rust and crud if you'd like to and maybe get a dremel in the areas the bigger wheels can't get to. I like 007's recommendation of getting the crud and as much grease off as you can if you are going to dip it in E tank, evaporust, simple green, or vinegar just to name a few.
good luck and nice work straightening out those pins.
That's exactly my plan. I've got the wire brushes and wheels, a dremel, and plenty of time. With our recent weather, I'm stuck doing chores inside.

Among other methods (wire brush, bead blasting, electrolysis, etc.) I have used wire brush the most in the past. While personally I do not mind the slow process and a lot more effort that is needed, at least for me the one big down side of this method is dealing with all the rusty dust which in addition to iron oxide and whatever other metal used in cast iron alloy, it might also contain lead, asbestos, etc from the remnants of paint.
To start with and stating the obvious most important thing is to wear proper mask/respirator and gear etc but even then if one is doing this indoors like in a garage (say in winter), the dust permeates and settles on everything. Honestly I was not too happy about the all rusty dust outside on my driveway either. If one has a well ventilated booth/cabinet this might be less of an issue (and which I do not have).
Obviously there are other types of concerns with other methods as well.
007: I'm guilty as charged for not always putting on at least a painter's mask and i might own 3 of the better ones with the cartridges. as i get ORGANIZED these will be hanging on my grinders and drill press or on a bench like my full face shield is hanging on my bench grinder that is on a stand. i also have a few ear muffs i need to put where i can see them too cause all too often we just grab the part and turn on the tool cause BAD HABITS DIE HARD.
since you seem to have a good grasp on this would you mind making a few posts on the SAFETY 101 thread and here's the link:

also I think we need you on the GET HEALTHY THREAD cause i bet a lot of the **** some of us have is caused by improper use of chemicals and tools besides the stuff we eat. here's the link for it:

I also started a thread Grinder Safety 101 a few years ago when i heard guys DIE when a stone or disk explodes so you might want to check it out and add your experience on it and sorry i don't have that link handy and i need to go get on my Schwinn recumbent bike now.
cheers and thanks again for all the good tips about safely working in our shops.
I'm not a fan of using chemicals if I don't need to. A wire brush or wheel gives me more control and allows me to select the areas I want to affect, whereas the other methods hit the whole piece regardless of what I want. So, I guess I'll brush the hell out of it and see what I'm left with. Maybe I'll change my mind after a few hours of brushing. I will definitely do a thorough de-greasing before I paint or finish it.
Outlaw has it right.
The mild sodium carbonate solution is totally safe. Compared to the minute particles of rust and broken off wires flying around in a wire wheeling session, the electrolysis solution wins from a safety perspective. But wire wheeling gets the job done quicker. Wire wheeling safety measures include using good quality particle masks to protect your lungs and eye protection or even a full face shield.

The other advantage of electrolysis is what I like to call "fire and forget", you do the quick setup and then let it electricity do the work for you (no effort on your part), you come back sometime later (might be several days depending on amount of rust) and you have yourself a nice and clean vise.
Plus the electrolyte can obviously get into every nuke and cranny (say inner crevices inside the static housing or the threads in the main bolt etc) that you can not get cleaned with wire brush and remove the rust from them.
Not 100% true. The E-tank process is basically line of sight to the anodes, so if you have a bar for an anode on one side only that facing side does much better that the back side. similarly, down in "holes" does not do as well. That said its still a great process for most rusty iron.
You can jury rig anodes to get better line of sight, but making sure nothing shorts out is important. One way to make it safer for an inadvertent short is to put a light bulb in series with the process. This makes a load so its NOT a dead short. I generally don't bother.
What is considered a good quality mask for such tasks?
I use the 3M brand disposable ones with 2 elastic bands rated at N95. If you use them regularly you can get a deal on a box of 20.
I will have to respectfully disagree on this point. Electron (technically ions) in a an electrolyte will travel through any path that is conductive and is not a line of sight issue.
Say you have a hypothetical U shaped bath tub full of water and you throw your toaster that is connected at one of end the U shape, will you stick your hand at other end of U shape that is out of site of the toaster?
Two different things gman. One is Electrical conductivity which behaves differently than Electrolysis which is more akin to a plating process. Also line of sight... Look at many plated parts. The "finish side" is great, the other side has something, but its a far cry from finished... you get similar here.
Do you get something? Yes, but best results are line of sight.
I've even had things like pliers where one side got de-rusted and the other did not. The rust at the joint prevented a good connection and only the part on the wire de-rusted...
If it were true, the guys doing motorcycle tanks could immerse the tanks and get results for the rusty interiors. They don't. They insulate the tank opening and get a wire inside and use the tank as both E tank and the part being de-rusted.
I use one of these when wire wheeling - doesn't get wet or fog up the safety glasses. Easy on/off, solid comfortable fit. Nice that they come in a resealable bag to keep the mask clean when not being used. Grab a couple when they are on sale.

It is the same as this; even comes in the same package:

I just ordered this 3M one for about the same price (scroll down for "Bought with")
Would these masks do any good if you have a beard?
This is the reason fire fighters are not allowed to have beards.Yeah, don't have a beard but did get tons of crud showing thru nose blows with the paper masks. Got a 3M and haven't looked back, use it all the time, every time now.
but while your beard my inhibit it's function, it also has some filtering qualities![]()

My tank anode surrounds the piece. I can tell when is working good by the outline of the part in the tank.
Bunk's Paramo No.3 & Morgan Chicago 45
15JAN18
The Paramo has FINALLY been completed. Its been 6 years. Damn I **** at follow through apparently. The end result is pretty nice though.
View media item 79649The color is Rustoleum Royal Blue, brush painted, two coats.
I wiped on a BLO/Beeswax/Turp mix on the bare metal parts.
I did the needle bearing mod to the lead screw, pretty cheap and easy.
I'm not 100% happy with my replacement of the missing back lash spring. I'll figure out something better later, hopefully not 6 years later though.
