Suppose I have a roughly 100x100mm post of (green) oak, that I want to route a 1m long slot out of the back for cables - let's say 20mm wide by 20mm
deep. I have a 1/4" trim router but nothing bigger. I also have a 65mm cutting depth circular saw.
Is that something I can do with the trim router, in which case what kind of router bit would I need? Or should I do depth cuts with the circular saw
and then try to chisel out the remains? Or some combination of the two tools?
Once this is done, I'm thinking of drilling a hole at the end of the slot
and having the cables turn to go through to the other side of the post. To do that they will have some kind of turn radius, so how could I make the end of the slot gradually deeper to meet the hole? Drilling a series of
holes of increasing depth and chiselling them out is one option I suppose.
I don't really want to make a huge hole to accommodate the bend inside the hole itself.
Any better ideas?
Thanks
Theo

With your tools, I'd go for the latter. Note that it will be tough
going for a 8mm trim router (I saw that switch in units, above)
to route a 3/4" x 3/4" x 39" slot.
Set the saw for a 3/4" deep cut and build a jig to guide the saw,
don't try to freehand it.
If you have a drill press, you can hog out the waste with a 3/4"
forstner bit, then trim with a chisel.

Again, that's probably your best option.

Thanks, that makes sense. Alas it's not a track saw which would make it easier, but can probably jig something up.

That's a good thought, rather than trying to chisel out big chunks of material.
be safe enough (then tidy up the edges).

A forstner bit to make stepped depth holes might work too. I should have a play...
Thanks all,
