How to use a ruling pen

There has been a great deal of interest on how to use the ruling pen. Maybe I should try and explain a little better how I use it. Many years ago, I was an apprentice draughtswoman. In those days you were allowed to say draughtswoman, these days it is called draughtsperson. I know it has nothing to do with how to use a ruling pen but I thought a little background may help you to understand. The Engineer would pass his sketches on to the draughtsperson and the plans were then drawn to scale in pencil. Once they had been passed by the Engineer the plans were then drawn up in ink - and this is where the ruling pen comes in.

You can buy different quality pens - I use a good quality pen such as “WILD” Heerbrugg made in Switzerland, but another very good brand is “STAEDTLER”. There are ruling pens that are not as expensive to buy. I have found that cheaper ruling pens take a lot longer to run in; you will find that it is inclined to scratch the surface of whatever you are working on, be it wood, canvas or paper. You can use a very fine sand paper such as 000 and gently sand the tip of the pen to help overcome this problem. I have also found that everyone is quite different with the amount of pressure they use, so treat your pen like a feather, gently does it. Providing the pen is filled properly it should work for you.

To fill the pen, I mix the paint on my pallet to the consistency of ink. You can use an eye-dropper to fill the pen or you can just pick up the paint with your brush - whatever you are comfortable with. I find it’s best to hold the pen upright in order to use it properly. My daughter has told me that she could make a little movie of me using a ruling pen, if that would help. Please let me know.

    Thank you for the info. I’ll give it a try but have never used one before. Maybe I can get some control out of it when using masking fluid, that would be useful. Many thanks.

    Many thanks for sharing the make of ruling pen you use. I just used a ruling pen for the first time to do some small houses on a watercolor, and I wish I had known about this useful little tool years ago! I am going to purchase a better quality pen, but in the meantime I will keep experimenting with the one I have on hand. It came in a drafting kit I picked up years ago, but until I started delving into architectural illustration I confess I had no idea what it was for.
    I also don’t know how to fill it in an efficient manner — I have been dipping it into the paint like a brush, and can get enough in there to do quite a bit of work, but would love to see a video of how to do it properly!
    Thanks again for sharing your knowledge!

    Elizabeth, I am glad you have found the ruling pen useful. Only yesterday I was speaking with my daughter about making the little video. Time is always a problem for me I am afraid - maybe I need to have someone to manage my time as I don’t seem to be very good at it! I promise that it will happen soon though. Elizabeth, I just love your work - I was so impressed with your camel. It is so nice to know that there are painters who feel as I do about camels.
    Please keep in touch.
