I've had a bit of time to apply to making my sprockets. In truth it is slow going. It's ticklish work and that's not restful. One twitch of a handle or too aggressive
on the cutting rate and much time is wasted. Unfortunately I found that when I cut the toothed disks, specifically the last group I was too aggressive when I
drilled the mounting holes around the circumference. In an attempt to trim some time and make the disks uniform in order to line up the teeth easier when mounting the resulting rings on the sprocket bodies I had drilled several disks at once.. Not the best idea. The small, #50 drill 'wandered' a bit and about half the disks have the holes too close to the outer edge. Can't really see it on casual inspection but it makes a number of disks quite useless from a functional standpoint so I'll likely use them as decorative items /spares on the models. I recall seeing a few photos of tanks that had spare sprocket rings in their stowage.

Also I purchased a number of steel sprocket disks from which to make rings from Martin at Geisswerk. I needed these to work with his tracks as they are
too tough on aluminium rings and happily they will engage properly with either the aluminium or bronze alloy track sets I'll be using. And they have the advatage of better wear and strength. Strength of my aluminium rings is a concern, they seem ok but they are quite thin by themselves.

BTW I was asked about what I'm going to do about the three non scale-like Phillips head screws in the middle of the sprockets. Either I will countersink them a bit further and seal / cover them with JB weld or similar or I will replace them with aluminium screw-rivets and make them disappear..

So the progress continues...
