Couple of other bits and bobs done
Blocks screwed to the underside of the top to keep it in place
This picture shows my original attempt at routing the hole for the plate, complete **** up.
You might have spotted that behind the section in the base where the router hangs and behind the small drawers is a space. This is where my extraction piping will go. I've got an idea on how the piping will work but still not completely sorted yet. Anyway the back propper needs to go on over this space. It will have a removable panel to get at the pipes easily and also change it about if its not working very well.
Panel jigsawed out and then trimmed straight with the router and guide rail
Corners chiseled out square
The inner edge had a thin strip of oak stuck on then it was screwed to the back of the cabinet. Sorry the photo is a bit close up, I'll take one from further back another time. You can also see a triangle of wood stuck on the inside across the corner which will support the back panel.
The insert I jigsawed out was then squared on the table saw
The insert also then had a thin edge of oak applied and a couple of blocks screwed on. These will sit inside the back frame to hold it in place and I'll just screw a toggle to th etop to hold the whole thing in place
