Hi all,
After many months of playing around i have finally worked out how to pull apart the classic Brown Bottle Jack.
Its such a simple yet effective design !!
Steps are as follows:
1) Find a small 2mm diameter pin on the top cap of the brown jack. This can be really hard to see - removing paint may be necessary. This usually is completely flush with the cap. The cap rotates freely.
2) Drill this pin out - make sure not to touch the sides - i.e. only drill out the pin. Don't drill the actual cap. AND NOTE - don't go very deep - you only want to go about 4-5mm. You will feel it give once you drill through pin. You don't want to drill into the sleeve.
3) Now this is the REALLY COOL Part. There are actually 3 small Ball Bearings that hold the cap onto the sleeve. These Ball bearings are located partially (1/2) embedded into the jack sleeve and the other half into a routed groove in the center of the CAP. These are spaced evenly at 120 degrees.
You can see the through the pin hole - as you rotate the cap around.
They are surprisingly easy to remove - flush with WD40 and then gently tap the jack when the PIN HOLE is correctly aligned and they simply fall out. One at a time.
Once the third one is removed you will be able to lift off the cap.
4) with the cap removed you can fully remove the jack centre and sleeves.
5) after cleaning and greasing everything simply reverse the process and the re-insert a new pin or solder (again just don't go too deep to hit the sleeve).
All the best and good luck !
