"Gaffa tape" is Gaffer's tape. From the production electricians in film and television studios. It's usually fabric and flat colors to blend in with sets and floors. It is usually stronger than duct tape, tears easier, and costs more. The good stuff also leaves less residue behind when removed, if not left on too long.

Another, maybe the original tape, was called 100 Miles per Hour Tape and was sold years after fabric covered aircraft wings went out of style as it was so universally useful. As the name suggests it was rated for repair of aircraft fabric to be used up to speeds of 100 MPH. cheers, Neville Michie PS. I have a type 36 post office clock running and it has a synchronising relay that forces the phase of the 30 second output pulses to the nearest 2 seconds, by rotating the count wheel which has a cardioid cam. At a fixed time every day this relay was energised from the central site to correct any phase creep in the clocks in the regional post offices. I have occasionally thought of linking it to a GPS time source. cheers, NM On 05/03/2009, at 9:38 AM, Michael Scheliga wrote: > "Gaffa tape" is Gaffer's tape.

Food for thought, thanks. 73, Steve -- Steve Rooke - ZL3TUV & G8KVD & JAKDTTNW Omnium finis imminet

For all those out there who don't have your own BPO 36 master clock, here is a youtube video that shows the detail of the Hipp toggle in action. The Hipp is the key to these clocks excellent time keeping. http://www.youtube.com/watch?v=lmx5iy4qwhI Yes I know, the sound track IS horrible! But you can hear most of the ticks... Not my video, I hasten to add.. For more info on the Hipp toggle, just google and all will be revealed.
