    I’m torn
    The dsg from 50’s onward are very special and capable of earning a living and have decent spindle bores.
    But made in Yorkshire
    I love Holbrooks but painfully old fashioned (except Herbert holbrooks)
    Silly spindle bore and left hand drive.
    But made in London then ESSEX!!:D

    Wouldn't call the model C old-fashioned - metric and imperial, D1 camlock, good speed range, micrometer stops. Spindle bore's a pain, but the spindle itself makes it worth it, seriously rigid - and the Model C were made in Stratford, so local to you ;)
    Mine has a label on i from the ARDE at Fort Halstead in Kent, local-ish for a Peckham boy like me, and funnily enough where my grandad worked as a toolmaker - I wonder sometimes is his fingerprints are on it :)

    i was just acknowledging your comment, not contradicting it. my bad


    I should have said, that confirms by thoughts that they have a tiny spindle bore

    Is the small spindle bore, because it wasn’t intended as a jobbing lathe. Ie, the pieces to be turned would have been cut the length, opposed to poking it through the headstock and lopping bits off.?

    Pretty much, yes - they were more or less dedicated toolroom lathes, a DSG will hog off material faster, but less accurately? Holbrook fitted as standard things like micrometer dead stops (with gauge trays like jig borers used) with trips that repeat within a tenth of a thou" on the power feeds, the quick-withdraw of the cross-slide repeats to less than a tenth (still, on my C13 that's older than I am), came standard with native collet set, immensely rigid. I've never seen a Holbrook made after WW1 with a gap bed, as that would reduce the rigidity! Most of the models had options like relieving slides and secondary gearboxes to run the cams for making TOOLS: taps, milling cutters etc., with matching spindle speed reducing attachments to give 1/8th speeds - down to 3 RPM or so for relieving. Very versatile kit.

    Accurate is accurate.

    Eee.... But you're in Essex - Traitor! :scared:

    I'd take the Holbrook, but something more recent than the B - like my Model C?
    I was well peed off that the last workplace wouldn't let me buy the H17 they expelled from the mech' workshop, I'd have made space for that...

    Haven’t got a whole lot done but been chipping away at a few things. Converted a grease gun to an oil gun and forced oil through the grease that had been pumped into all the oil ports. Dropped the oil out of the main and lead screw boxes. Cleaned the filter - it’s a funny style with heaps of very thin steel plates clamped together that you rotate every week. Wasn’t filthy but had quite a few what likes like paint chips. After a long chat with the Castrol helpline discussing the original oil spec (460s at 200*F redwood) and some penciled notes I Have some AWS 100 coming for it...

    Been waiting to clean it til after I finished lubing/servicing.

    Can anyone tell me what this knurled knob is? It will turn, but is stiff. It’s not not a filler cap like I thought, or at least not threaded... seems like some sort of adjustment?

    With the experience I've had so far on my Harrison Mill, I agree with the final statement 100%.

    Turns out it was just the lid handle - once I got cleaning I found it was an incredibly nice fitting inspection hatch. Gave it a pretty bit scrubbing with degreaser, rags and wire brush.

    Now it’s got fresh oil, cooling system tested ok it’s almost ready to go. Just need to give the race ways a final polish and work the main spindle bearings out... I’m wondering what to do hear though - someone (I assume it’s not factory) has put grease caps on the bearings. I’m still not sure if they’re plain or roller/ball. I thought being a 720 rpm (not an 850 or 1200) it meant plain, and under the paint it kind of looks like it has main caps. But now I’ve found a hand drawn diagram in the papers I have showing am opposed ball bearing system. Either way, not sure whether to flush the caps out with oil in grease gun then convert to wick/reservoir oilers, or just pump more grease in. If all the other lube points weren’t full of grease I’d think it was legit, but as in general greasing isn’t good enough for most lathe oiling I don’t see how it’s good for the most important points in the machine. Still haven’t got a dial gauge but putting a 4’ bar in the spindle and giving it a wobble nets no apparent play so I don’t think any major harm has been done...

    That is turning into a lovely bit of kit.

    Grease caps could be correct for those bearings. It'll run hot if they are over-greased though.
