Hi Guys
I`m looking for a long pendulum rod to fix a synchronome clock I`ve just got. Infact, the clock is totally missing pendulum and fixings which does make things more flexible as I can make parts to suit but I`d prefer to make them as near as possible to the original design.
The pendulum rod should in an ideal world, be made of invar, 5/16" dia by 43 1/4" length. I can`t find any 5/16" or 8mm invar of this length. The nearest I can find is 6mm but at £30, I just can`t justify the cost at present. I`m happy to have the clock working in concept and any inaccuracies I`ll just have to adjust every so often.
So basically, that leaves me using silver steel or even bright mild steel with the critical dimension being the length. The piece I purchase must be at least 1100mm. Anyone got a UK supplier of 8mm steel of this length at a reasonable price.... probably including postage if they are not North West based.
Any help appreciated!
Chris
