Trying to make a black terminal for an old AVO without spending any money.

So far I have a bit of brass with a 2ba thread, a collar and a head 12.25mm dia and 8mm deep. I also have a bit of acetyl with a suitable cavity bored in it.

The first attempt at sticking brass into acetyl with Gorilla Glue was a failure, it practically fell out.

Once reasonably secure I plan to turn down the outside, polish up a bit and part off and put AVO back on shelf.

Any ideas how to glue - or other methods

I don't know if this is helpful; depends on cost.

Could you knurl your brass bit, heat it up and melt it into the acetal?

I'm not familiar with what your trying to do but before dental fillings would actually stick to teeth the answer was to undercut the cavity for retention and make it non-round for antirotation then pack the amalgam in.
When Epoxy or CA don't work then I sometimes fall back on good ol' copydex or evostick

Having used JB weld for various metal working jobs with good results, they do some adhesives for plastics which may be suitable for your use. Link

GC has the remedy. Often additionally secured with a screw for further security.
