Oh, yeah. All the old glue will come off. There are two "former" resting places clearly visible. Original, one after that and now it sits lower, and further right.
I'll measure where it was originally, and then clean everything off. Probably acetone so everything is off before I re-attach. Taping it in position for a day after I set it, it will be there long after I die.
I may look into some heavier grease for the mechanics. The table is nice, and a new power supply will make it nicer, but the arm mechanics are very noisy... (work perfectly however).
