Sorry if this is a bit too off topic for general, I won't be offended if it gets moved
In my quest to have a house with all the mod cons like door knobs I've rushed out and bought some of these:
All was going well until it came time to fit them #-o. No matter what I do they bind up when turned and stop the catch from popping back out.
Here's what I think is supposed to happen... The door already has a rim lock fitted through which I slide the plain knob and threaded square bar. I think the idea then is that I screw the fixing plate onto the bar and then screw the fixing plate to the door - this locks the plain knob in place. Then the other knob is slipped onto the bar, screwed to the door and the grub screw tightened up.
Where it goes wrong: if I screw the fixing place all the way up to the door the knob binds when turned in one direction because the bar is threaded so it pulls the knob tight against the lock. If I do the grub screw up the knob binds very tightly. I'm not completely sure why the grub screw causes it to bind but I think it's because the bar and knob are not quite turning about the same axis.
I've fitted two of these so far (another 10 to go) and the solution I'm using is to put the fixing plate on back-to-front (without screws) and take the grub screw out of the non-lock side knob. It's not an ideal solution but it seems to work.
I would love to know what I'm doing wrong though, this is driving me completely nuts (and I think LOML is fed up with me being in a bad mood because I can't figure it out). A million thank yous to anyone who can correct my muppetry.
