Default HOW TO renew the cable link between the private lock and the door latch

HOW TO renew the cable link between the private lock and the door latch


The symptoms of cable failure, and the means of access will be found in these threads of the Technical Help Forum:
www.the75andztclub.co.uk/forum/showthread.php?t=302103 (postings Nos. 2&4)
www.the75andztclub.co.uk/forum/showthread.php?t=302744


Materials required:
- 0.68mm dia. stainless steel wire rope from: www.tecni.uk (they sell single metres)
- 3 No. solder nipples, type BN575/55A from: www.venhill.co.uk (sold as individual units)
- Liquid flux type A8 for SS from: http://www.solderconnection.com/ (125cc bottle is least available)
NB: postage, in all cases, far exceeds the cost of the materials!
- Oddment of scrap timber, ply or MDF (about 300mm lg.)


Method:
Step 1. Create a jig by drilling 3No. sinkings, 6mm dia. X 3mm dp. in a straight line, at 134mm centres, in the scrap material.






Step 2. Saw a screwdriver slot in one face of each of 2No. nipples.


Step 3. Thread 1No. slotted nipple onto the cable, with the solder recess away from the cable. Take the end which emerges and turn it back through through the nipple, forming a loop.





Gently pull the free portion of the cable while restraining the turned-back end, until the loop is within the solder recess.






Step 4. Heat the nipple, brush in A8 flux liquid, then apply solder to fill the recess. Allow to cool.


Step 5. Thread onto the cable, in order, plastic sleeve, unmodified nipple, plastic sleeve and second modified nipple, with solder recess away from the sleeve.







Step 6. Insert the 3No. nipples into the sinkings in the jig. Pull the cable straight and cut it 7mm past the final nipple.




Step 7. Lift the final nipple and turn the free end of cable back on itself to form a loop, as Step 3. Again, restraining the turned back end, gently slide the nipple along the cable until it drops into its sinking. If the loop has not sunk fully into the solder recess, restrain the cable and push the loop so that the free end emerges beside the cable.


Step 8. Solder the middle and final nipples, as Step 4, above, and check that the previously-cut slots are clear. The cable is ready to install, but you are not there yet.


Step 9. The two ‘wheels’ in the ‘banana’ must be modified to accept the new cable as the solder nipples are larger than the Valeo swaged originals.
a) Open the slot in the lock-end ‘wheel’ by filing symmetrically to widen it, and deepen it such that the cable sits on the bottom of the circumferential groove.
b) The two sockets in the lower wheel need more care. Don’t try to drill them out as you risk fracturing the separator. Instead, file away from the separator until the nipples are a snug fit in their respective sockets.


Step 10. Use a screwdriver if necessary (hence the solder-free slots) to rotate the nipples, ensuring the cable sits fully in the groove.


Step 11. Mount the wheels in their casing and refit the cover.
