scribe

If I hade a good scribe I may not have been asking about my earlier thread. What is a good scribe for making center lines down the edge of the blade to grind to?

I use one I got from K&G. Does what I want. Prior to that I used a handmade one, but find the store bought unit much more accurate, and easier to use.

I adjust it to give me parallel lines about 15-20 thousands apart.

There's lots of choices. As Mike said some folks make 'em.

Here's one I made:

But now I just use a steel caliper. Easier setup. If you don't have a caliper, you need one anyway.

I have a pair of dividers but the steel is too soft to get a good line. Where can I get a pair of calipers that will have a hardened scribe on it?

I believe that you can also use a drill bit. 1/4 stock use a 1/4 drill bit etc. Put both on a flat surface and the point of the drill bit should hit the center line. That being said I got a scribe from Texas Knife Supply.

MAC tools has an excellent scribe with a tungsten tip and a magnet on the other end.it came with a plastic boot to protect the tip when not being used.$5 or $6

This took me a lot of skinned up fingers to figure out. Put the scribe in your vice and then scribe your knife edge. For the rest of you that figured this out the first time. Take pity on us slow learners.

So that's how it's done. . I thought there must be a better way.

I use a dial height gage and a tool room grade granite surface plate. The height gage has a carbide tip for scribing.

The height gage that Patrick mentioned with a surface plate is a great way to go for stock removal blades.

If you order the Surface plate from Grizzly, be sure to order something else with it...I've ordered 4 of them and got something else at the same time and they haven't charged me huge shipping fee's...

If you're forging, and want a center line scribe, Pop's or uncle Al's (I can't remember) makes one that will scribe on a distal taper which works pretty well until you get near the ends of the blade. I taped a piece of white paper to the wall and use that as a background to try to judge straightness on forged blades...
