Some more progress.

Spindle is shot. Bearings are pretty loose and some parts have clearance.

Drill chuck is Kawasaki! It looks like it is beyond repair, but I'm tagging it along and see if bring myself to disassemble it.

There is one thing I wonder:
This three step pulley has two bearings. They seem to be grease lubricated and shielded. However on top the pulley there are two conical holes with stamped "Oil" in them. Is this just case of using old stock pulley after product design? Someone might have changed the bearings.

The spline shaft looks very nice, but awfully skinny for my purpose. I was surprised to find that splined hub was made of plastic that appears to be nylon, judging from the looks of it.

Not sure if the pulley assembly will disassemble civilized manner.

You have come to the same conclusion as me , I just have a head but it's in good condition and the chuck cleaned up like new , now idea what to do with it .

Jeff, yours looks very much same than mine. This looks like pretty good for drills up to 10 mm. The bottom bearing looks like a very standard deep groove ball bearing. It's only a single small bearing and can't take huge amount of axial load. Original circlip had faild on bottom and had been bodged on mine.

I'm not sure yet what to with mine. I'm between rebuilding/improving it littel or making it a tapping stand for this:

It is quite interesting to know a way to do these things but it hardly cost efffective. My car repair saved a loss of noclaims bonus and my excess on my insurance cover is more than my cost of raw materials is less than having a whole new drilling machine. I had a quite uprated staking and rivetting tool which I made to improve on the earlier one which was made from three small car conrods. I had the castings and all the bits to do the headstock but the motor was a bit more than a complete new drilling machine which was only about £30 with a small vice. No holding down bolts- but who cares?

Whatever turns you on?

Cheers
Norman
