Managed to sit down and loose 5hrs fettling today. My other half, bless her, let me setup the B&D Workmate in the kitchen to do the work on the grinder. Having put the plug on it and made sure nothing fouled the wheel, a quick run to see how it sounded and how much vibration. Not at all noisy and the mass of the thing meant almost no vibration, I guess the grind stone is pretty close on, but a later job is to pull it off and rebalance.
I've started by stripping down the tool post/head assembly. You can see in the springs picture the new finger hammer has had some use tapping parts loose and removing pins etc. I had to clean off the thick grease with included abrasive particles, I replace this with LM2, making sure everything is cleaned. You can see the diamond stones and drill I used to remove burrs and clean mating surfaces. You don't need to de burr, but I would rather they didn't work loose sometime in the future so for me it's a job worth doing now. The horizontal motion of the grinding wheel is nice and smooth, however the lower tool post bar is gritty and has some tight spots, they will be dealt with later.
Last picture is some of the casting defects I found, nothing serious but I like to pick the loose stuff out and fill them with JB Weld. This serves dual purpose, to seal in any further loose bits and stop dirt finding its way into a hiding place for later escape.
