Before I start, can I say DO NOT make this tool to aid splitting your clocks unless you are confident in your abilities to perform the task.

There are people recommended on this site who can do the work for you, they will do a great job and protect your precious irreplaceable clocks.

If however you are like me, and like the challenge of doing as much renovation work as possible on your bike, then you may find this tool useful.

I bought a 4â€￾ drain pipe joint (110mm Underground coupling – single spigot) and a 4â€￾ Jubilee Clip from B&Q. The 4â€￾ joint has 4 internal tags.



1) Cut the pipe down to leave approx. 8mm of pipe above the tags.



2) Cut a section out of the pipe, do a little bit at a time, so that when you fit the clock and tighten the pipe round it, there is a gap in the pipe of approx. 5mm, this will ensure a tight fit round the clock when secured with the Jubilee Clip.



3) Fit the Jubilee Clip and tighten the pipe down most of the way.



4) Place the clock into the pipe face down and the crimp ring will sit on the tags. Tighten the Jubilee clip to hole the clock securely. You can now gently prise up the crimp ring using a 1/4 socket with a flat head screw bit inserted, working carefully round the clock.



Hope this is useful to some of you, but again I stress please DO NOT undertake this task unless you are confident you can complete it.

All the best

Neat looking tool there. Some thought went into that

I used two sharp flat bladed screwdrivers to seperate mine. One to prise open the flange - the other to lever against so's it didn't mark the casing any more than it had to be. There is a how-to on Reproduction Decals in Canada's website.

I wish someone could come up with a tool to put em back together though so's it's not obvious they have been opened

PSS have done a feature this month eye opener no substitute for experience tho

I used a Marples No 5 chisel and a lump hammer for 10 mins and then a screwdriver and pliers for 10 mins and then sent them to Al Marshall.

Nice wee touch the outside support will deff make a good difference, used to just use a screwdriver (done the job in a fashion I think) ,it was a long time ago, regards the reassembly a can seam roller would be the way to go, I used to be an engineer in the canning industry and basically the can (Clock) would as it rotated be progressively reduced with shaped discs, obviously a big machine would be no use but the principle could be used with a HAND operated set up
