Woodworking marking gauge made from a single wood stick

Graminho, in my opinion a sweet word, is how we call this traditional marking gauge in my mother language. From Wikipedia, "A marking gauge is used in woodworking and metalworking to mark out lines for cutting or other operations.". Wikipedia also tells you: "The purpose of these gauges is to scribe a line parallel to a reference edge or surface.". You have probably already used a primitive version of this tool: when you pick a pen and draw a line parallel to an edge, by pressing your finger against the edge to maintain a constant distance of the pen's tip to the edge.

I always wanted to have one, of course :). But the ones I found were quite expensive, and that is what usually puts me to think (there's a saying which states something like "the need makes the inventor" ;)).

So I looked at my small material stock and this squared section 1.2x1.2cm (1/2 inch), 100cm (40 inches) long piece of wood draw my attention. I picked Inkscape (excellent OSS 2D vectorial drawing application) and designed this marking gauge using only this wood stick, a nail and white glue (also known as "glue for wood").

Before starting with the construction, I did a paper model of the headstock, just to have a feeling if the measures I choose would adapt well to the hand. They did.

I just found an instructable on wood chiseling.

Great job! I take it that English isn't your native language. If that's the case, great translation job too!

I asked because of your statement: there's a saying which states something like "the need makes the inventor"

Pretty close! The actual phrase in english is: Necessity is the Mother of Invention

Thanks! Ahhh... yes.... that sounds better :). In fact, in my language we have another, similar way of saying that, but it has 2 words that I couldn't translate at the time (sounds something like "necessity sharpens the apparatus (the thinking)"). By the way, I just changed the nail length from 25mm (1inch) to 20mm (3/4inch). I used a 25mm one but I think it will be more comfortable to use with a 20mm one.

My father was an Inventor, He actually had two products succeed that we frequently see; The bread bag (and the machine that fills it) and the Diatomaceous Filter (used most commonly with tropical aquariums and swimming pools). He used to tell me that the secret to invention isn't, "How to build a better mousetrap" but, "How to make the current mousetrap better, simpler and cheaper." This thinking has followed me through my profession in computer design & programming. The simplest solution is usually the best one.

I totally agree with you, and I can say that I also let the "simplest solution" guide my life. I never forget the day I saw a mention to the KISS principle in a networking book: "Keep It Simple, Stupid"! This is just soooo true.

Very nice work! What type wood did you use ? Always remember measure twice cut once
Nuno (author)  awoodcarver7 years ago
Thanks! I used "northern pine" wood, it's very light and soft. I didn't pick any special type of wood; in fact, at that store it was the only type of dense wood available. Yes, "measure twice cut once", I think it comes in all books about woodworking :)

For me, measuring twice is never enough. It's usually the third measurement that catches my previous two oversights! :)
