"Reminds me of fitting bearings to shafts of Induction Motors when you don't have a press. The non-press technique (if offshore for example) involves putting the motor 'shaft' in a freezer overnight (to contract it) , and heating up the bearing in a pan of oil (to expand it).I wonder if heating the table part of the design in oil, would have any advantages in this design, as it does when fitting motor bearings?PS: Try the bearing fitting method described above, at you own risk (hot oil!)"
