When cutting boards for a project, it helps to mark the boards with useful information (which side is to be exposed; numbering the corners of a frame; etc.). Rather than using a pencil for this, I use blackboard chalk. Chalk is easier to read than a pencil and it’s easier to erase. Chalk can’t take the place of the fine line of a pencil, but it sure is better than a pencil in many instances.

I watched a video of Sam Maloof marking a board to cut with a piece of chalk. And then cut the board on a band saw using the chalk mark. So if it is good enough for Sam Maloof, it should be good enough for us.

Here I go against the grain… I use pencil except for the very detail (accurate) cuts in which case I use a thin knife mark. Pencil marks may sink into soft pine and present minor problems, but if you’re using hardwoods, use a pencil. This is not to say that chalk users are wrong, but I don’t even know who Sam Maloof is. As a matter of fact, I use pencils in my final prep routine.

I scribble all over the surface with a pencil and sand out the marks with a 100 paper. I again scribble and sand it out with a 120 paper. I do it again using 150 paper. I then dampen my surfaces with water (not soak) and after about 20 minutes, when the water is dry, I can feel whiskers on the surface and I sand these off with 180 paper using my hands, not a machine sanding. Anything higher in grit will close the grain in hardwood.

This works great for me, but I’m sure there are makers of fine furniture who would disagree with my final finishing method. My method works best for me and I’m sure their method works best for them!

I don’t use chalk for marking. Always a pencil. I use a white pencil on walnut but still always a pencil. I do however use chalk heavily with labeling. I like to label all my parts so as to not get confused and always ensure I’m oriented properly.

I use a Pencil also, an “HB”/ No. 2 (Same Lead by two names) and use to Sand the Marks off. PAIN!

Almost by accident I found that a Regular Eraser takes the Pencil Marks off Very Nicely!

Now I’m using one of those White Rectangular Art Erasers. It works even better.

At least 90% of the work I do is in Pine. Yes, The Pencil leaves very small grooves but I haven’t done any Finish Sanding yet. When I do, they Quickly Disappear.

I’m using chalk for the part id process, and to highlight any areas that need work.
In the midst of a pine DVD case my youngest started, getting his pencil marks out has been tough, might as well have used a knife and filled the gouge with black paint.
However, thanks to a post elsewhere on this site..denatured, or rubbing alcohol takes it off very well, my wife stands by the white art eraser as well

I use chalk when possible, but find it hard to remove from the more open grain woods such as oak. Since that’s a lot of what I work with I’m normally marking things with a pencil.

As to erasing pencil lines, I use a dedicated crepe sanding belt cleaner and/or rubbing alcohol. I’ve found that the particular wood I’m using will require one or the other, or both, to completely erase the marks.

I use chalk to label board sides, directions, etc, but I use a sharp pencil to mark cuts.

Used pencil all my life, tried chalk last fall on a cradle I built (Peruvian Walnut – quite dark) and liked it, but have since gone back to using pencil on ash, oak, mahogany and exotics.

Bernie, if you google Sam Maloof, you will find amazing designs and items he has built, and you may not agree with the style, but have to enjoy the craftsmanship.

On dark woods I like to mark them with a knife and the rub chalk into the cut lines. I prefer fine pencil for white woods and those marks are very easy to remove with a little ethanol (denatured alcohol). No sanding, no erasing if you don’t make trenches with your pencil.
