Not exactly today, but I've been gnawing away at the casting I made for the gear banjo on my universal dividing head.
I still need to make the stub arbors for the idler gears, then make a start on producing the full set of change gears. The ones shown on the machine are from a set of mystery change gears I picked up, only a couple of them have appropriate tooth numbers for the dividing head and they all have splined centres, I have bored and keyed the centre of three of them whose number is amongst the ones I need. They are 14dp which seem about the right size for the job, I'm on the lookout for a cheap set of 14dp involute cutters.
A spinoff project was this slitting saw arbor so I could cut the clamp mount for the banjo, didn't want to take the vertical head off the mill. It makes use of a 30NT / 1" bore toolholder that came with a bunch of other stuff, plus a couple of the horizontal mill arbor spacers.
