I'm not too sure about how these new scalloped edge top designs will play out. What do you think?

They look really nice to me, both still and spinning.

Gorgeous!

I am now re-reading a book titled The Symmetry of Things and this reminds of the beautiful drawings in the book. Maybe one day (when I am retired and have time) I can get myself a rose engine

Several years ago, the AAW published an article by Jon Magill on how to build a relatively inexpensive "MDF" rose engine. The article and plans are still available on Jon's site. Here's the link: http://www.whidbeyworks.com/root/MDF_Rose_Engine.html


If you're willing to spend some serious money ($5k +) on a life-changing tool and hobby, then have a look at the Lindow rose engine. It's pretty much the best turn-key "hobbist" machine/system available: https://lindowmachineworks.com/lindow-rose-engine-menu/lindow-rose-engine-accessories/


And if you have virtually unlimited cash ($85k +), and want the best modern design rose engine on earth, consider the limited availability Made machine: https://madelathe.com/

They look great -- especially the tri-color version. The scallops will cut into spin time, but who cares?

Those machines look fascinating!

If that's the one by Conway et al., I'm very impressed, ta0! Gave up a third of the way through, as I just couldn't follow their unusual approach -- despite more than a passing familiarity with crystallographic symmetry.

Actually, I found it much more intuitive than the traditional approach using group theory. I enjoyed the first section, struggled but followed the demonstrations on the second section and gave up and just looked at the drawings on the third section  I may give the third section another try. But even leaving out the demonstrations, the book is eye candy

No doubt about that. Maybe I'll have another go at it.

If that's the one by Conway et al., . . .

I just found out that Conway died back in April due to complications of covid. That such genius could be extinguished by this stupid virus is very sad

Amen.
