Can You Resharpen the Disposable Blades for Portable Planers?

I've built many of the projects and jigs published in your magazine with great results. One I have particularly enjoyed is the Scary Sharp Jig for plane blades and chisels (June 2000 issue). I can see my reflection on the blades after I'm done - cool!

I own a Delta 12" planer with double-sided disposable blades. I would like to sharpen them with sandpaper but they don't fit in the Scary Sharp Jig. Any ideas?

Ben Moll via the internet

I can't recommend sharpening disposable blades, though I admire your thriftiness. The problem is that disposable blades are not adjustable once installed in the cutterhead. This makes replacing the blades a snap but makes them impossible to regrind. Any grinding will change their width slightly, and without a mechanism to adjust them in the head, they'll be out of alignment with each other.

You could, however, hone the knives a bit a time or two. After that I suggest you simply spend the cash to replace them.

How Can I Remove Rust From My Planes Without Destroying Their Value?

I just finished reading your article on metal-bodied jack planes in the April 2002 issue -a very interesting article. I have three jack planes that I want to fix up to use. I was wondering how I can clean the metal on the sides of the planes and what to put on them to protect them from rust. I do not want to ruin the value of the planes, but I also want to start using them more.

Unless your planes are collectibles, such as the Stanley Bed Rock series of planes, I wouldn't worry too much about destroying their value. Jack planes are as common as dirt for the most part and should be in the shop, not on a shelf.

The most non-invasive (and best way) to remove rust is to try using electrolysis. It's a fairly simple procedure you can do at home with a battery charger, ammeter and baking soda. For a complete explanation of this procedure, visit: http://users.interconnect.net/nlindsey/ rusty2l/electrolysis/electrolysis.htm

I've seen many planes treated using this procedure and the results are quite amazing. A more continued on page 18
