I think the thing to try would be to see what your natural heat decay is from the setup you propose. Eg heat it up ( using any means ) then stop the heat and note the decay profile. Unless you have insulation, you might find that you don't need any holes at all
WOW. Some real restrictions there Bruce.
A 0.5" height restriction seems quite a restriction although I cannot think of a SMT connector that I use that would be higher than this.
But it seems like a lot of work when a modified toaster oven would get you there much quicker, especially if you have other pressing jobs to do. If you need the challenge, then you’ll learn a lot in the process.
Is there a way to see inside the oven as it is operating?
I suppose it's possible to trust the gauges but I always like to verify the solder paste has turned shiney by looking through the oven window.
I suppose the top ventilation plate could be made of glass

I was having a little trouble finding my ambition, but I finally have the PCB drawer constructed. I am providing two photos, one without wire mesh and one with the wire mesh set in place, but not yet expoxied.
Since deciding to have two heating elements, I have been having trouble designing a coil, which fits well with my ceramic terminal block. As a result of this decision and difficulties with the design, I have also decided to go back to a similar wireform as the original, but instead of just one heating element, there will now be two, and instead of having a maximum temperature of 800 F, each element will be able to get up to 1000 F.
Of course these decisions necessitate the need for more wattage, which my power supply is incapable of providing. I will now need a 12V, 5A power supply. Luckily this upgrade is not too expensive, and if I decide to make more, I will certainly need a distributor to supply them.
Here is a link to the power supply that I will be using for this experiment: https://newark.com/multicomp/mc141010/adaptor-ac-dc-12v-5a/dp/02AC7188
Can't help but think you're going to want an insulating knob for pulling the drawer out, though.
