Your Own Design / Re: 5 Cylinder radial somewhat based on the Morton but not much
« Last post by Mike R on Today at 01:23:17 AM »George,
Great build. I love round engines.
I appreciate the difficulty with fins that size and depth. I needed effectively the same cut depth and width as you, on my radial engine and it was 13 fins and 9 cylinders.
I eventually gave up on the lathe and used a slitting saw in the mill to cut them (as well as changing to a more forgiving cylinder material than specified).
For anybody else struggling with thin fins this is another option if your patience is being tried by thin lathe bits on small machines in difficult materials.
