Bolt Hole Pattern Calculator

I found this bolt hole pattern calculator as a result of watching one of Tubalcains videos. I'm not sure if everyone has seen it! Very helpful if you have a DRO on your mill. Just Google " Bolt Hole Pattern Calculator". It works great!

There is a (free) program to calculate bolt hole circles and a few other things as well. Check it out and download from here.

I am currently adding more features to the program. I am currently working on calculations for making worm gears and the home made hob to cut the worm wheel.

Most DRO's have that built in.

kd, not everyone here has a $1200 DRO setup. Some of us use the basic iGaging version, which can benefit from a facility like these. Even without such a simple DRO, you could use the graduated dials (with care) to follow the coordinates provided by the calculations.
