Where can I buy or how can I make rust resistant ferrules? Answered

I'm interested in making my own tools for ceramics carving and trimming and brushes for decoration, using some wonderful mountain laurel branches that I have.  They need to be rust-resistant because they will come in contact with water and moist clay all the time.  Which is why you have to have a ferrule -- other wise, the swelling/shrinking cycle will loosen the blade or brushhead. 
I'm thinking under 1" in diameter, some as small at 3/8".  I don't have a lathe, so I can't turn nuts as I've seen on other searches.  I've seen some neat ones out there for making your own handles for gouges, but they're really expensive.  Where to go, what to do?

Get a tubing cutter from a plumbing store.
Get stainless steel tubing at the required diameters.
Cut tubing to desired length of ferrule.
Install ferrule.

Step 2: Coat tool with a waterproof finish.
              Deft would be good.
              Thin deft with thinner used to thin deft. Arr.
              Coat wood and ferrule and let soak in good.

This may be a slightly more expensive way to go about this but if you already have the tools you need and need to make them rust resistant you can try this. 

In scuba diving tanks are made out of two metals, aluminum or steel.  Since steel rusts and we take them in the water you can see the problem here.  There is a chemical solution made to coat the inside of a scuba tank that will prevent it from rusting when/if you get any water inside.  It is called "Compound O" and is made by a company called Global Manufacturing.  2 oz. of this stuff will make a gallon of this greenish looking stuff that inhibits rust.  You're supposed to let it dry on and since most scuba tanks don't get water inside of them they don't need to be treated often.  Given that it seems your tools will be getting more exposure to water you may need to play with mix ratios and drying time but I imagine if you treated your tools after every use you'd probably have pretty good success with this stuff.  One gallon will cost about $60 and since it's a 2oz. to 1 gallon of fresh water mix ratio the 1 gallon of Compound O you get should last a VERY long time.  Hope it helps.  Let me know how much success you have with it.

Anything made of copper, brass or stainless steel would work fine.

Do you have an example of what the ferrule should look like?

Use thinwall copper or brass tubing.  You can just crimp it down on the handle.  Both will eventually corrode or preferred word is acquire a patina.  But this takes a long time and won't hurt the utility of the tool.
