I suggest you get the book, "Beds", by Jeff Miller and rethink your joinery.
Consider making a knockdown bed frame. The knockdown hardware can be
mortised into the headboard and footboard with your router. The only
joinery will be on the headboard and footboard. Although best done with
mortise and tenon (easily done with your router and bandsaw and a jig), you
can also use dowel joinery. this eliminates weak miter joints and gives you
a quality, traditional bed.

hi group,

as my very first serious WW project, I'm planning to build a bed. I'd
be keen on using the knowledge and experience of the group to avoid
serious (and costly) mistakes.

The first problem where I'm stuck:
How to cut 45 degree mitres on the ends of a 90 x 7.8 x 1.5 inch
board, along the height of 7.8 inches with a 1.5 inch thickness?

Note that I'm almost a complete beginner, but still, I don't want to
go with mortise and tenon joint.

The boards are beech, I have handtools, bandsaw, plunge router.

Should I take it to a pro with a router table, or are there other
ways?

Thanks for your input:
