Hi Corby, I don't have experience with the ion pump you mention but have repaired several rotators (aluminium casting) where the threads have become very worn or stripped using a product called recoil. These are manufactured in Australia but available around the world. You drill out the drill specified for the size kit you are using and then tap the hole with the tap provided in the kit. Once the hole is ready you insert the 'Recoil' using the special tool provided and then break off and remove the tang following the instructions. Result - a threaded hole probably stronger than the original. These may also be known as Helicoils. There is another method that uses a special solder but that requires heating the object up to the temperature needed to melt the solder and may not be suitable for what you want. Good Luck with the repair Regards Malcolm _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
