caotropheus Posted January 10, 2020 Share Posted January 10, 2020 I just bought from a local antique dealer what looks like a Schlegel EMF-150 bench vice. I hope the 70 USD I payed were not too much. The overall aspect and jaws of the vice are OK but the threads are shot and need repair. It opens and closes but every half a turn or so it "turns empty" as if the male and female threads disengage. Later on, I will show pictures or video of the repair. The ruler is 40 cm long, the jaws are 150 mm wide and the vice weighs 43 kg. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted January 10, 2020 Share Posted January 10, 2020 Could it be one of the "fast action" vise where you slid it to touch and then engage the screw to tighten? Quote Link to comment Share on other sites More sharing options...
caotropheus Posted January 10, 2020 Author Share Posted January 10, 2020 I do not know, I did not explore the vice yet, just brought it home, took pictures and posted. Once closed, when I turn the screw to open, it turns several times until threads engage. Something is not right... Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted January 10, 2020 Share Posted January 10, 2020 Looks like you need to pull the screw out and examine it. Quote Link to comment Share on other sites More sharing options...
caotropheus Posted January 17, 2020 Author Share Posted January 17, 2020 After oiling, the vice works very nice and smooth, the ways are really nice and there is no wiggling of the movable jaw. I inspected the threads, still work, even though there is some wear/abrasion I think I can replace the threads if needed. So, where is the problem of the vice? Well people, take a look by yourselves. the piece of paper is locked between the handle and the collar somebody disregarded vice maintenance and throughout the years the collar wear to the extent that the handle would push against it upon screwing. So much so that handle wear off bolts' head securing the collar and a bit of the collar it self. You can hardly see the silhouette of the bolts. Luckily, collar + bolts were made of a softer material than the screw/handle. The vice's screw head is half loose with a gap of 15 mm to the collar upon unscrewing Now, let's have some fun repairing it... Quote Link to comment Share on other sites More sharing options...
caotropheus Posted January 31, 2020 Author Share Posted January 31, 2020 (edited) The vice works fine now after replacing the collar. The "original" collar is 5 mm thick with the inner opening of 54 mm. I replaced it with a collar made from mild steel flat stock, 10 mm thick, 45 mm inner opening. Now the screw is in place, everything is tight and snug and the moveable jaw moves very smoothly and "precise". There is no wiggling what so ever. To remove the old collar I had to grind away the remaining old bolts' heads and it come off right away. The bolts were not tight and unscrew easily with hand pliers. I mounted the vice to this height adjustable pedestal So I had to adapt the mounting plate I used for the previous vice. et voilá Now that I look at it, the vice is really massive!
