Easiest way to remove rust from spindle and what paint to use

[RogerIvy]

Is there a better way than wire brush and rust remover to get this rust off?

What is the best paint to use? Some form of Hammerite?

Angle grinder with a wire cup brush will have it done in minutes.

soda blast it

sand blasting?

Fertan Rust Converter - 1Ltr - Frost Auto Restoration Techniques

Using Fertan Rust Convertor is a real easy way to achieve a corrosion free metal surface. The patented formula only targets the rust and and once all the rust has been dealt with it then protects the metal to prevent new rust from forming. FERTAN is incredibly effective in cavities and joints...

Find someone who can sandblast it!

Rust remover doesn't remove rust, it simply makes it inert and changes colour.
Rusteater used to turn the rust blueish black.
Best option is shot or sand blasting which removes all rust flakes then a couple of coats of hammerite..... Follow instructions for second coat.

Take them to a powder coater. They often have a shot blaster machine.

Soak in a bucket of Oxalic Acid.

A good way to remove rust is using electrolysis.
Find a bucket big enough to submerge the item and fill it with a mixture of washing soda and water, one table spoon of washing soda per litre and mix till dissolved.
Find a strip of stainless steel for a sacrificial anode like an old kitchen utensil, a fork or similar. This should be clamped or bent to hang over the lip of the bucket to connect the terminal.
Get your battery charger out and connect the positive to the anode and the negative to the item and switch on.
You can leave it for a full 24 hours or longer, the rust just sloughs off and you'll end up with a brown froth in the bucket, which is all the rust and a nice clean, rust free item.

Edited: I meant washing soda, not baking soda.

This is a great way to remove rust without wire brushes or shot blasting.

Shot blast then powder coat.

Because it's a spindle, you should really strip it apart before attempting most of the suggestions above, all of which would cause damage the spindle's bearings to one extent or another ?

I'm planning to strip it down anyway in order to change bearings. Having come this far it would be crazy not to change bearings. It goes without saying that I'll need to be careful not to damage the bearing housings.
I'll be cleaning and painting before reassembly with new bearings.

Could this cause damage to the bearing housings?

I think you would probably need to strip it of bearings before the electrolytic process because I'm not sure what effect it would have on an installed bearing.
If you mean the machined surface that the bearings are pressed into, then no, it will have no effect. The process will only remove rust, it has no effect on surfaces that are not rusty and therefore will not change tolerances.
If you're restoring it, then IMHO new bearings should be on the list as a matter of course, no point doing all that work only to have to strip it again later to replace bearings.
Just one more point about the process, it may be nescessary to create an attachment point in steel, a bolt or wire, to allow the terminal to be attached above the surface of the solution so that the item is fully immersed.

Thanks for this Vic, as you will see on one of my previous posts I'm stripping down to prep for painting and new bearings anyway. Would be crazy not to do this.
I could use mechanical ways of removing rust but think electrolysis could be fun.
...just don't want to damage the machined surfaces.

It is fun and I guarantee you will be amazed at how efficient the process is at removing rust. It will even take off paint that has a layer of rust under it.

There's plenty of videos on youtube showing the electrolytic process and what it does.
Like this one:

 

[Vic. Parsons.]

I've never used vinegar on the items I've cleaned because I mostly used it on cast iron hand planes and other tools.
For cast iron, I used methylated spirit to clean off afterwards before painting, anything else starts the oxidation process and a layer of rust will appear unless it's either painted fairly quickly or oiled.

cheap coca cola leave for 24 hrs minimum,, or phosphoric acid diluted,

I've used the electrolysis method with the terminals reversed, to "sharpen" dull old files. Just need to clean any oil or grease of them first, I've heard the dishwasher does a good job on them.

Completed first carrier as a test. Left on electrolysis for about four hours, washed and brushed. Painted with red oxide.
