Todays Project - What did you do today?

[f350ca]

Need a smaller 4 jaw for the Summit, the 16 inch only closes to a little over inch, so have to pad the jaws if I need to cut a metric thread on a small shaft. Found a deal on a Chinese 8 inch, $114, looks reasonable.
Was given a D1-8 backplate, I believe part of a chuck. A little rusty but with some Evaporust and some polishing the taper and pins came up nice.


There was a large lump in the middle that needed to be removed. The one surface was hardened, got glowing chips for the first few thou as I was facing it.


Managed to get a small indexing lip in the bore of the chuck, the back was flat, no index on the outside.


Now need to drill and thread the back plate. Will turn some of the OD off but can't quite get to the 8 inch dia of the chuck, I'd be too close to the mounting pins, they're about 7 3/4 on the outside.
Will mount it then grab the chuck body in the big 4 jaw to turn it. The spindle flange is too big to get it down to where I want it.
