  • For me to keep it off was the challenge. I Started by working out how much I needed to eat for maintenance, through calculators and counting my calories for a couple of weeks.

    Then I just brought a small deficit of a couple hundred cals, and increased exercise; making sure to go for a walk each day, started lifting weights at the gym.

    Now im halfway to my weight goal. But it was all about setting the habits and keeping them going, turning down extra cake in the office or having a smaller lunch to balance everything out, now I dont have the same cravings I used to. Its been a slow year but I am happy with it.














  • The main one is the resin that is bring used, that will have a shelf life like paint or glue as the solvent will evaporate. The second one is fibre primers that are used to help the resin integrate with the Carbon Fibers can degrade and cause improper bonding between the fibres and layers. For fabrics this is normally over a year but for prepregs (where the resin already in the fibres but not set) is generally a year and will need testing for a longer shelf life.

    Another issue is the storage you want a cool dry environment and covered to avoid contamination from other rolls/prepregs. Additionally the other thing that worries me is although salt water is not an issue to the fibres and resins themselves when you add metal to them the salt acts as an electrolyte and will cause galvanic corrosion “rusting” away the fasteners and causing damage to the fibres in that area.

    Not to mention Carbon Fiber is best for coaxial (along the length of the tube) tension not hoop (around the tube) compressive forces. And differences in the layup and curing process can impact the viability of the final part which is why lots of places will weigh the resin and have a procedure to soak the fibres and lay them up as well as sensors to keep the pressure and temperature with a margin for curing, to keep the variability between the parts minimal.

  • I have found its more through tips from colleges and shared trauma. In my experience its the intial change to nights thats hard once I’ve done 2 my body has started to adjust.

    - either stay up late and go to sleep early morning to start transition 
    
    - nap alot during the day and use caffeine to pull through 
    

    Once on shift you need to keep active mentally and physically, being idle is the killer, make sure to take short breaks, keep hydrated, it is very easy to over snack but you need to keep eating.

    The change back after isnt too bad imho you can gey some sleep straight away and but wake mid afternoon and can start to pull back to normal.

    make sure you get paid for the rest day after when coming back to days you have worked that time you have taken the sacrifice and deserve to be compensated for it.

    Are theres 12 or 8 hour nights? One is nicer.
