Is there a reason not to use a spoiliboard 1" bit to make a large pocket cutout? It would save a lot of time and I could use rest machining for the smaller areas.
Shallow depth per cut?
I don’t think such tooling has a great material removal rate — if you want faster roughing I’d suggest an 8mm collet and 8mm tool.
You can use a large bit for a pocket but as @WillAdams suggested do a small depth of cut. For a Shapeoko 3/4 a 1" bit is removing a lot of material for a trim router. If you have a SO4 Pro or an SO5 you can cut deeper but even with a spindle a 1" bit is a load. For any large surfacing bit you want a shallow depth of cut and a fast IPM. Woods like cherry and maple will burn quickly with a slow IPM. So shallow cut fast moving. With a large bit you will get a big circle on the inside corners and you can use rest machining to cut that rounded corner down smaller if that would suit your astetic of the project. You can do multiple rest machine operations with smaller and smaller bits just tell the 2 or 3 one the diameter of the last bit used.
Thx to both of you for the advice.
Much appreciated
