Hello all!
A few months ago, I got the McNaughton Center Saver coring jig used off of eBay. It was advertised as "used only a few times," presumably because it is difficult to set up. While searching YouTube, I came across Gavin Brunton's channel. He designed a spreadsheet to calculate and a jig to set the entry angle based on the diameter and depth of the bowl blank. I took his instructions, built the jig in CAD, and then printed it on my 3D printer.

The 3D model files can be downloaded from https://www.thingiverse.com/thing:3366592
Prints can be ordered from https://www.thingiverse.com/thing:3366592/apps/print/#apps . Note the this is a third-party service and I don't make any money off of it, and can't support any technical issues with it.
Gavin's Channel with the original videos: https://www.youtube.com/channel/UClXgFhhTjQxrOJQIT3Go61g
He has information in the comments of this video on how to get the spreadsheet he designed to calculate the angles.
