Getting the DSG into service
Well it had to sit outside for a week but its in now and I have given it a good once over. Im blown away by how little wear and abuse is evident.
It still needs to be moved another 4 feet or so back towards the bridgeport and put on some hard rubber feet. I thought the compound was knackered but it was just the bolts holding the nut on were loose, only has 0.008" backlash, cross slide closer to 0.010" still by far the least worn machine i have.

Getting the chuck off proved . . interesting, I dont really know how you are meant to remove these fastlock mounts but you kind of have to push each of the three cams down against a spring and lock them on place by turning them, then i just couldnt get the chuck to budge so i gripped a bar in the jaws, gripped the other end in the toolpost and used the carriage to haul it off. Fast is certainly not the word i would use for this, I can see why they moved to camlock so soon. The spindle nose looks very good, no dings or trapped swarf. I do not look forward to making a backplate for this.

After this i wired it in, tested the Newall dro, filled the headstock with oil and fired it up, no issues except i put wayyyyyyy too much oil in, and if all came pouring out the breather of the oil pump round the back, does anyone know if the sight glass round the back at the bottom of the headstock should be the standing oil level or running oil level?
A big mess ensued, sawdust to the rescue.
The only real wear i could find was in the feed drivetrain, the big 100 tooth gear has a flogged bronze bush in it, should be a simple fix. This thing is rugged on a whole new level, the headstock lid is a two man lift, it weighs 37 kg and is 3/4 thick all over.

Does anyone here have a DSG of this era (1952)? There are a few odd things, its metric except the leadscrew, and has roller bearings but the lowest speed range. real oddball.

Ralph are you sure that is a breather on the oil pump?
I think that it might be an oil supply line as oil pumps don't normally have a breather and if you had the oil to the level line
in the oil sight glass the oil level should be correct.
Beautiful machine m8
cheers, shed

The hole it came out of is about 3mm across by feel on the back of the cast housing that the sight glass is in, well above the level of the sight glass. There isn't enough room between the housing and the headstock for a fastener or plug to get in or out. I don't really know what the deal is I'll have to do some research.

You might be able to get to it from inside the headstock, better flex those muscles again......
