So, looking (again) at CNC engraving/cutting machines like the CNC 3018
(eBay, Amazon, etc). Does the panel think that using several/many passes
this sort of machine could cut 15mm oak boards?

How deep must the cuts go?
Id use a jig router for full cuts on that

CNC cut jigs might be an option tho :-)

Ta.
It needs to cut all the way through.
I haven't got a shed, a workshop, or any room for decent equipment (saw
or router table etc). And my garage is full :(

I don't see why it should not, although it will depend on how fine the
detail needs to be. For example, if you wanted (say) a wiggly 1 mm wide
slit you are going to be struggling to get 15 mm depth with multiple
passes using an end mill. AFAIK engravers usually do a single path at
one depth, do these have computerised control of the third axis and
hence the ability to do multiple planar passes (a bit like a 3D printer
in reverse).

And it might be quite slow.

Some friends of mine have one of the computerised laser cutting tools
that will do something like 4 mm ply quite neatly for craft fair type
stuff. Obviously the edge finish will drop off if you try to go deeper
but that might be OK for applications that you can hand finish to final
dimensions.

2mm per pass apparently - so 8 passes will do it! (That's the "pro"
version - not sure if the normal one has less spindle power or not)

No experience of using one, but looks intriguing - gets through 20mm MDF in a
roundabout way:

Dust clearing looks to be a pain, but otherwise quite a neat thing.

Did you go for one? Have you got it? What is it like?
