Thread: Update on Rust Removal Gizmo

Gentlemen,

Here is an update on my quest to discover a means of rust and blemish removal on razors while still retaining Gold Wash and Etching.

What you see here is an Air Dental Polisher and a Dental Turbine unit. It acts like a micro sandblaster and is used by dentists to remove stains and blemishes from teeth when using high grit and low pressure, or can remove cavities in place of a dental drill when using low grit and high pressure - with anything in between.

It uses sodium bicarbonate as a high grit abrasive and aluminum oxide as a low grit abrasive. Other grits are available.

The hand piece is attached to the turbine unit and the turbine unit attached to an air compressor for supply air. The turbine unit has all the regulators and mixers required, which I thought I was going to have to put together myself. It also has a water supply and foot switch to operate it off of. The water is used to contain the abrasive in a localized cloudlike area and act as a lubricant.

The Dental Turbine Unit was the hard part to track down.

The whole set-up costs about $150. I am saving some money so I can buy one and test it out - if only I could stop buying razors : -)

I will keep everyone posted on how this works out.

Cheers!
David

Maybe you could start a thread entitled "Calling All Dentists" to see if you could borrow one!

Or if you are like me you can take your toys to the dentist and let him see them. My dentist let me use an old sonic cleaner before I tried to buy my own. He uses his fo rwhat I wanted touse mine for, cleaning cartridge casing and firearm parts. I wonder what other cool used things he has that could be of benefit in my various hobbies.

Sounds like an interesting experiment.

Also in the dental realm, I have wondered if scales could be cast from the same material that caps are made from. Don't know if caps are cast or cut from blanks. I guess I should search into that.

This is an air-abrasion unit. It's not used to clean teeth per-se, but rather it's the newer version of those old prophy angle and the sandy paste that they used on your teeth when you were a kid. When I did my residency at a periodontist's office, the hygienists used these daily. If you're using them to remove rust, then yes, it will sure do that. However, it won't remove pitting or anything like that. Additionally, it will more than likely leave the surface frosted and will have to be buffed out.
