What do you use when tracing the shape of a cab? I use an aluminum scribe, but it is very thin and hard to see when I cut cab.

Number 2 pencil and remark when required.

Number 2 pencil and remark when required. Won't it come off with the water as you are forming the cab? |

I go around the template multiple times to build up the graphite. After using the trim saw, I redraw and then again if the line fades.

I've had good results using a fine-line paint pen. Doesn't wash off or fade, doesn't stain the material, and easily scrapes off with an Xacto blade if you change your mind. You can get them at stationery, craft, and online stores (just make sure you are getting the finer tips). I'm also using the same pen to re-mark the backs of slabs in my personal collection - I've had too many adhesive labels fall off and other marks smudge off or fade. The aluminum wire you're using is good (and cheaper), but harder to draw with and harder to remove if you want to change the mark. I like the white paint as it is easy to see on any color of rock (even white), but any bright color would probably do. |

I bought a carbide tipped scribe, but agate just laughs at it, aluminum nail works good. Stay away from a sharpie marker on translucent or transparent material. Even acetone and time on the flat lap couldn’t completely get sharpie off of blue lace agate.

I read somewhere online to use a paint pen, like from Michaels or a craft store, and that it would scrape off the back with a razor blade. Haven't tried it yet.

I use old aluminium knitting needles that have differing tip widths.
Typically, I decide in pencil and mark to cut with aluminium. Each Knitting needle can be made into at least 3 scribes.....I bought a bundle of them at a garage sale for .50 cents.

I use 0.125" Brass rod. I sharpen it to a point and do a heavy scribe with my template. I use sandpaper to erase my marks if needed.

Stay away from permanent Sharpie in any color. The silver and gold ones work great but they're super thick tips. I use a regular graphite pencil most of the time, no the water does not wash away the lines but if you're cutting with oil that will take it off. I just got a fine line paint pen from Michaels but haven't had a chance to use it yet. Scribes, wires & nails are great but yes they're harder to see.
