I’m still not quite sure what went wrong. I’ll post a couple pictures and then bullet point of my process

Inside left/inside right

#

And this is outside left/outside right

#

Problem: inside has ~equal gaps that look like they should close up nice
Outside is tight preventing it from doing so

#

Process:

  • flatten pieces
  • check twist w. Sticks
  • square edge of board using reference face
  • dado stack groove in door styles and rails (contractor saw)
  • shoot ends ensuring squared edge used as reference against shooting board fence
  • use square/knife to define shoulder
  • use wheel gauge to define cheeks
  • cut shoulders w. Chisel
  • fit joints with reference face and router plane. Then non reference side with router plane and chisel when required
  • dry fit seemed good
  • glue up noticed these gaps
#

What I didn’t do:

  • check edge for twist
  • clamp dry assembly (everything looked good with no clamps)

Can I get some larger shots for context

Currently trying to fix fibres I uh … went more than finger tight with clamp before realizing the front was preventing me

#

Is there a full tenon for the center rail or just stub tenons?

#

Stub tenons everywhere

Is there any twist in the assembled piece?

#

Zero twist actually I’m surprised

#

How tight are the panels in there?

#

The edges of the visible panel bottom out before the stub tenon does in the groove (maybe 1mm clearance)

One sec

Can't draw on my phone

#

Thinking my middle rail ends maybe werent as square as they could of been when I cut joinery

#

Or the edges of styles werent 90

#

Red gaps match, everything else is tight

#

So, looks like something prevented that left corner on the panel from sitting tight in there

#

Pretty well equal yea

#

Pretty sure this is what stopped it front side

Maybe some plywood fibres got trapped in there during glue up

Ah crap, I don’t think it would of fixed the problem but uh totally glued top and bottom rails in reverse order
