Not too hot. Too much heat will cause a metal chamber for example to expand and pull away from the epoxy endcap, it doesn't show visually until you pressurise it and it starts leaking...

I typically go for "high ambient temperature", 35-45ºC

2 - How much curing time do you save?

At the above temperature a part will cure fully in 8-10 hours as opposed to the usual 24.

I'd love to reduce curing time for epoxies but seeing as you don't do it at home, you either don't own an oven or a conventional oven is not appropriate.

Aside from not wishing to use the same oven for foodstuffs and spudgun parts, as I said very high temperatures are generally not desireable, and most kitchen ovens can't really keep the correct temperature range.
