Almost any acid

>will work. Traditionally they soaked files and rasps in urine to clean and sharpen them. The idea is that they rust faster on the flatter surfaces and less on the edges, hence sharpening. Acid sharpened rasps and files can be sharper than the originals. Muratic acid, diluted hydrochloric acid works, and is readily available, for cleaning concrete and mortar.

When mixing up an acid bath always put the ACID INTO THE WATER, if you do it the other way it will EXPLODE!

Good luck

>Thanks Stephen. That sounds like a pretty important piece of information to know about.

>I place them in an electrical bath connected to a Volta pile. The bath is distilled water and sodium carbonate (washing soda). A few hours in the bath magically removes the rust. Then a few hours in direct sunlight and the files/rasps are ready to use. I never use wire brushes to clean my files or rasps. If I am working with gummy resinous woods I dust the files/rasps with whiting, (chalk or calcium carbonate) to prevent the swarf from fouling the teeth.

Re: Price for rasp re-work?

>Hey Scott--

What does it cost to have a rasp (e.g., Nicholson 49/50) redone by these guys? I can't find anything on their website.

Thanks.

>I think that I will experiment on some of my older estate sale files before I commit my 49 and 50 to this process. Thanks for the information Steven.

Sorry Dave, I don't remember...

>I used them back in the pond daze. I did notice their internet special 2 files or rasps sharpened for free to new customers.

>mine is actually not a stack of cups but a lead/acid battery, early nineteenth century improvement over the 'original' battery, unless you believe the 'Bagdad battery' story which predates Volta's work.

>So would this be similar to the electrolysis process that I have read about for rust removal using a car battery charger?

Re: Volta Pile?

Stephen in Utah

>Yes it is the same thing.

Tell and show us more

>Stephen,

This Volta Pile is really intreging to me. Would you show us some pics of yours and how you use them? what is this new "battery jar" in which you speak?

The producing/creating of electricity has fascinated me since childhood, and I firmly believe that we can produce what we need without the use of fossil fuels and by damming up our waterways. Unfortunately I have never gotten active in the persuit of electricity generation, but it still does interest me after all these years.
