oxide layer on aluminum or brass and meat transfer

[syrah]

Does the oxide layer on these kind of housings cause enough thermal blockage to make it worth removing the oxidation before attaching them to an optical plate?

Not sure, but you may want to edit the title

Short answer: No.

@Ally... take anodised parts for example.

@BBQ's... yes, it may affect cooking times.

Thermally,no. But, if you intend to use an adhesive to attach the parts, then you will produce a much stronger bond if you remove the oxide layer from aluminum. The re-oxidation of freshly exposed aluminum is so fast that you cannot then apply adhesive quickly enough. The easiest method to solve this problem is to place a small quantity of adhesive (epoxy is a good choice) on each surface to be bonded and use a small piece of sandpaper to abrade the aluminum under the layer of glue. Attach the surfaces. The bond is excellent.

In terms of meat transfer, transfer all you have to me! Especially rib eyes.

Heat transfer, no effect.

How can I abrade something which is under a layer of glue?

Simple ...... you sand/abraid through the glue and sandpaper gets messy, so you throw it away !

Right. I avoided joking about reusing the sandpaper. The easiest abrasive I have found is the maroon, 3M hand sanding pads. Tear off a small corner, take a piece of plastic film typically used to cover food in the refrigerator, use it to keep your finger clean and the pad deforms around your fingertip. This limits the abrasion to where you want it while not slipping off your finger.

Neat trick ...much cheaper than silicon surgical gloves.

kinda off topic but close enough to post is I can attest to how fast aluminum forms the oxide layer, in fireworks some people make there own flake aluminum by getting cheap atomized aluminum and crushing the stuff in a ball mill, when you reopen the milling jar the aluminum can generate heat when the new oxide layer reforms, one guy did that with atomized magnesium and almost lost his face from the resulting fire.
