Recently responded to a post on here about a non functioning QR vice and I suggested a broken spring may be the problem....... Well the day after I posted, guess what? The spring on one I was refurbishing gave up. Seeing as this model has not been made sine the 1930s then It has done well to last this long, but a replacement might be hard to find, unlike say a Record 521/2 0r 53.
The vice is a Parkinson Perfect 16, otherwise in good condition, even though its has spent 30 years at the back of someone elses damp shed before I got it.
Anyway, the spring fits the same as the Record, in a recess in the front jaw, flat coiled bar, but larger than the record.
Spent a while googling spring manufacturers, forums, ebay etc etc but nothing looked hopeful and so I decided to think about what exactly the spring did, and if it had to be that particular spring in that particular place, and came up with an idea that would tension the half nut againt the threaded rod but still have enough give to operate the quick release...
It took about 20 mins in all. just knocked it up to see if it would work, more a proof of concept than any thing, but it works so well Its staying as is and getting fitted like that.
Might be of use to someone else with a QR with a broken spring...........
