I'm building a Murphy bed with 18mm plywood.

I would like to use knock-down joints for the sides of the base (outer-frame). My research led me to cross dowels (see below)

When doing some tests joining with cross-dowels, I was confronted by the following challenge:

Because the planks are large, I have to use a hand drill. Drilling accurately is quite difficult. For the edge I There are jigs to help with this but they're so expensive I'd can't quite justify it. I'm considering building my own jig with wood/perspex and metal drill bushings.

Alternatively, I considered using the another type of connector that is often used vertically in knock-down beds.

Specification: Size: 52 mm, Width: 17 mm, static load Both Horizontal & Vertical approximately 250 kg

I have a hand router (in case a recess is required).

Concrete Questions

Would this type of connector be structurally as sound as a knockdown joint?

What must I consider when using such a connector?

Design: bed Cross dowels: cross dowels alternative connector: connector

    Re. using a hand drill and having difficulty in drilling accurately enough, that's easily tackled. Obviously you start from accurate layout and after that good technique will ensure the holes are plenty accurate enough, if necessary by drilling successively larger holes starting from a small pilot. But if you want to build a jig to help by all means do so, it's good practice apart from anything, if it's only for this job though no need to bother with metal bushings which will simplify and speed its construction. – Graphus supports Monica Jan 26 at 17:21
