I was tightening up my Record 52 1/2 and all of a sudden there was a snap followed by The rear bracket has come off. Apparently the pin snapped off flush with acme screw.
I took the screw out and tried driving the pin out but it won’t move. Does anyone have any suggestions? I am dead in the water until this is fixed.
Thank you all in advance.4 February 2015 at 10:15 pm #124375Is that the pin that holds the three holed plate ( for locating the two guide rods and screw ) in place?
I would try drilling it out.
Thanks j1mmy. Overnight I soaked the end of the rod in PB Blaster, a very aggressive penetrating oil. I was able to drive it out this morning. It measures 0.187 inches in diameter. Now I have to look for a pin. It may be tapered. There also appear to be a washer or 2 that are missing. I sure would like to find a blueprint of this vise.

You could perhaps try making a mold of the hole, if you’re not sure. In the past I’ve had some success using a file and W&D sandpaper to shape a nail in the drill press, it’s rudimentary but it works for the most part.
moon that is a great idea. I can enlarge the hole to take a pin diameter that I can find. I am also thinking of trying a roll pin. It seems this part simply holds the screw in position and does not take the stress of clamping. I can’t figure out why the pin would break. Perhaps something was binding. I’ll let you know how my experiments work out. Thanks again.
This is weird. I received an email from someone who mentioned that the pin is tapered. I have lost the email and his reply is not on this thread. If you are out there, I want you to know your reply was greatly appreciated and I have a couple of questions:
1. Can you tell me the length of the pin? Mine was snapped off flush and I can’t find the missing parts.
2. A picture I found on the web shows two washers. Are these flat or is one “wavy”, that is a “spring”?
I hope you see this. Thanks again.

I have attached a photo I took when building my bench of a record 53 vice which I assume will be a similar design The important thing I would think is the washer which is quite thick and a bit concave, being a bit concave will allow the acme screw to rotate in the end plate. The pin needs to be quite strong although from what I can see there is only any weight on it when the vice is opening not when closing. As long as the pin does not fall out I would think a straight one would be ok the fact that it sits in the concave part of the washer would hold it in place. The shank of a twist drill would be good.
Have another look for the washer.Attachments:

I like the design of yours better. I am thinking there never was a washer in place. I have torn the workshop apart and found nothing. I am going to try using a collar with a setscrew instead of the pin. I got that idea from another website where the guy also drilled the recesses and the rods then tapped to insert bolts. I’m not up to that. It appears the washer is key in my design to keep the dog bone in place. I’ll let you all know what finally works. Thanks for the pictures.

Screwfix Split Pins BZP 135 Pieces Product Code: 13547 £2.07 INC. VATJust in case anyone experiences a similar problem and looks at this thread in the future, here is where it stands.
I ordered roll pins (split pins) and while waiting for them to arrive I installed a collar with a setscrew. II also put a washer between it and the dogbone. It appears to be working fine. If problems develop I will replace the collar with a roll pin.
I also discovered that the dogbone was bent into a slightly bowed shape. I put the ends on two pieces of 1/2″ scraps along the edge of the bench, convex side up, and used a clamp to pull it straight. It now seats more securely on the rod ends.
So far so good.
I will add to this post should something change. As for now, thanks you all again for the suggestions, ideas, and pictures. They were most helpful. -
