Simple Division for Finding Equal Parts
This is a technique I used daily when I was working on the bench especially when laying out square to rounds. Most of the time, I would break the circumference of the round up into 16 equal parts on the top view of my layout. I would then proceed to developing the pattern for the fitting by using the information gathered from the top view. I would establish a triangle and using the information I would find the true lengths of the lines needed to develop the pattern. I then would establish the collar for the top of the fitting by multiplying the diameter by 3.14. Once the blank for the collar was made it was time to establish the length of one of those sixteen equal parts so we could proceed with the pattern development.
I know that one could use a calculator to find the length of the segment for the layout but I rarely did, in fact most of the time I never even knew the actual length of it. What I would do to achieve the mysterious dimension is simple. I would take my tinner’s rule and place the zero end of the ruler on the bottom left end of the collar blank. Measuring down the stretch out of the collar, I would push the ruler upward across the blank then making the ruler lay diagonally across the collar. Where the end of the ruler intersected with the end of the blank, I would set the ruler on a number that was simple to divide. Then the division process would begin. After finding the center the collar was found, I would layout the remainder of the collar into the required segments using the same technique. The “Finding Centers Fast” technique can also be used in relation to this if needed.
I know this may seem to be a lengthy process but with practice you can become very efficient. I also know there are easier ways to find the length of the segment but this process can be very useful in many situations, not only for square to rounds. Put this in your mental tool box, you may need it some day.
Hope all this makes sense.
