Sorry HG , I thought I new what you were doing but, what are the ply things for ?
The port light outer ring as below goes through the the cabin side internally the ply spacers are glassed in and the outer rings will slide inside the spacer
In the above photo SandS visualize the outer port light ring sliding inside one of those spacers epoxied to the inside of the cabin. When its all done I will use
3M 4200 sealant run a bead around the inside of the outer ring slide the outer ring into the cut out and e bend those tabs sticking up the opposite way and screw the out rings onto the spacer inside the outer ring is then been fixed permanently to the boat.
Once this is done on one side I can then install my western red cedar on the inside of the cabin walls around the port light spacer.
Then a trim cover goes over where the cedar butts end at the port light . Once thats done I put sealant 3M 4200 around the flange of the inner ring of the port light and then screw the inner ring to the spacer.
In the photo below you can see how the two parts of the port light (outer ring , inner ring) fit together when completed.
But I have a slight adjustment to make the outer rings are to wide , and as Cisco surgested a while ago will be reduced using a slitter blade ( very thin cut off blade for a 5 inch angle grinder. and re weld the out rings securing tabs.
Once the ply wood spacers have cured and are fixed to the cabin side permanently Ill slide the outer rings into the cabin side and through the spacer . Ill then mark the out ring how far in protrudes though the spacer on all 6 port lights . cut them all with the 5 inch grinder and weld the tabs back on and its ready to install permanently. In the mean time a work mate will finish off the cabin side fairing and paint work. I'm taking a port light cut out with the original cabin side paint on it to Marine timbers in Seaford for a color match .
So todays effort will be adding more mat to the stove bulk head ( but I am running low on epoxy)
Gluing the ply wood spacers into position using Bote Cote E glue its a two part epoxy thickened glue
http://www.marinetimbers.com.au/sc/105/epox-e-glue Ive been emailing Andy Miller ( a you tube ship wright) concerning the port lights over the last few weeks so I do over look any thing and stuff it up.
He had a concern that using normal epoxy between the cabin side and the ply wood spacer and then clamping may bring stress between the cabin sides and the ply wood spacer which may distort the cabin side after releasing my clamps. So the bote cote E glue will be used and clamping will be very slight just to keep them in postion while the e glue cures . I am hoping this will take up any irregularities between both parts spacer and cabin sides
so today is glue the port light spacers and if I have any resin and hardener left Ill use all I have to add more mat to the stove bulkhead and then clean the boats interior its a real dusty and dirty mess. The cleaning might happen after work on the way home next week a couple of hours every night. Ill see how it all goes together today

Taking the cut out below for color matching this week
