My workshop is fully heated and Temp controlled with a Thermostat. The frame was slowly brought to room temp of approx 17deg over 3 or 4 days before applying epoxy and then workshop was kept at this temp for constant 3 days 24/7 afterwards then rails fitted after 6 days of curing.
This was using West systems 206 Slow hardener not 209 but still it caught me out, which I should have known better after doing several machines with epoxy.
Thats what i meant before, but could not explain it better. Machine,epoxy and room should be same temperature from the moment of pouring to the moment ready to mounting.

I have done some experiments and epoxy will even cure at 5C though not advisable.
