From scratches to slots

The plans of the diligent surely lead to success, But all who are hasty surely head for poverty

When I was at the Axminster demo day – which, as it turns out, wasn’t at the beginning of May at all. It was the 5th of April – I bought various items. Some files, some marking gauges, some Camellia Oil and the stones.

Some woodworkers like to use the marking gauges with the scratch pins untouched. This means you get a scratch on your work. A tried and tested tequnique. Others like to create knife lines instead of scratches. This is useful in that one can drop one’s chisel into the knifed line for a clean edge.

David Charlesworth, in one of his books, shows how to modify the pointed pins of a marking gauge to make them into little knives.

In much the same way as I forgot which month I went to the Axminster thing, I once again forgot to take a “before” picture. But here’s an after picture…

You can see I’ve filed away one side of the pin to give a tool which will cut a half “v” groove instead of making a scratch. The vertical part if the half “v” will end up as the show surface. In others words, if you imagine the “knife” in the wood, the waste to be cut away will be on the left, the slope side of the “v”.
To do this, I pulled the pins out, put them in the metal vise and used this…

…a diamond file, to abrade the pins. This is a dirt cheap diamond file, but it did the job on the hard pins. An ordinary file just skidded off.

I did this on three gauges. Here’s some more photos…
