So I was playing with the parallel offset formula, [tan(1/2 offset angle)?centerline distance] and discovered that if you just use the decimal of the offset angle (.30 for 30?, .45 for 45?) as a multiplier, it gives you the same value within 1/32". Just something I thought I would pass on as I had never heard anyone use this method.
Offset angle. Multiplier. Difference using simple method.
45?***** 0.414213562. ** 0.035786438
30?***** 0.267949192.* * 0.032050808
22.5?** 0.198912367.** 0.026087633
As you can see the difference is less than 1/32" (per inch of center to center distance)
I think this would be easier to remember and to explain to others. I hope this proves to be a handy tool.
