Generous Donation

A generous reader, who knows well my propensity to lick windows stamps mailed me an ancient tome about gunsmithing.

It includes information about checkering and stock finishing.

I think I have a clue about why I was unable to hold a line with the 75˚ cutter but could get a pattern with the 60˚ spacer.

There's a section that talks about how some woods will take 20 to 24 lpi and some won't even take 16...

This is with proper 90˚ grooves.

My sudden uncontrolled line jumping is probably caused by the wood being too soft to accept the wider cut and the side of the diamond sloughing off.

Harder woods and finer grain structure accept smaller diamonds from more lines per inch!

I have no idea what kind of wood I've made my first attempts with, but it's definitely soft.

Thag lurning!

Thanks Miguel!

    It is my pleasure. Yes, there is Internet, but there is still a lot of info in old books.
