Today I am cleaning up a Dawn 125mm offset cast semi-steel engineer's vice (often found on eBay AU in new or used condition).
As found it was missing jaws and had received a rattlecan all-over paintjob at some point in it's life.
Next to my 100mm SG offset:
Someone missed while welding?
Old grease, new grease:
Nut - looking a little furry:
The paint covered the sliding surfaces too:
Dynamic jaw removed:
The usual Dawn arrangement behind the handle - washer, spring, washer, split pin:
While it's a bit beaten up there do seem to be more inclusions than you normally see in Dawn vices in the casting surface - note the pits that would normally be hidden by the jaws:
A few cuts taken too far:
Some bonus metal on the slide:
After the extra metal was removed where relevant and the paint stripped, some jaws were knocked up out of some scrap plate:
The inclusions were left as-is - no filler here! Some fresh paint:
Lubed with some Castrol Spheerol LMM:
The handle is 5/8" in diameter and 10 ½" end to end (15.8mm and 267mm respectively). Next to the SG again:
As a long-standing fan of the offset vice (holding long things vertically comes in handy regularly for me) I would heartily recommend this style of vice over the standard engineer's vice. My daily vice is an offset 100mm SG unit and it has stood up to quite a beating in the time I have had it. Weighing in at a little under 40kg, it's certainly not a small or light vice but it is Australian-made quality and with care it'll still be working well in another 50 years.
Specs-wise, the jaw width is 125mm, the max opening is 145mm, the closed length is 492mm, it's 294mm wide and 231mm high. The currently available part number is 60180.
As far as age goes - this one is post-metrication, so post-1970 or thereabouts - beyond that I can't say for sure. Perhaps the markings on the nut would provide more information there but I am not aware of any specifics regarding that. The quality of the casting surface on this particular vice is not up there with the best of the Dawns I have refurbished but it does not appear to have hindered this vice from withstanding a lot of use/abuse and in the short time I used it it performed admirably with little slop and great clamping ability.
