it's amazing how a rather expensive quote for a repair concentrates your mind....
i woke early this morning (too bloody hot in bed)... and lay there thinking about maybe fixing the tacho myself. as i have 2, both with the same problem, i figured if i bu55ered it up i still had one i could get fixed professionally.
so, i formulated a plan.... plan A, (there was no plan B)
i'd grind off the lip at the back of the bezel then i could pull the whole lot apart, make a new needle, clean everything fit the needle reassemble and glue it all back together.
amazingly plan A worked a dream... made a needle from a bit of a coke can, painted with red hammerite glued on with a spot of araldite, sprayed various bits with matt black, glued it all back together with clear sticks like sh*t.
hey presto ... £145 quid i can spend up the pub :-)
2 hours start to finish. now, maybe i'll fix the other one, and make a smaller needle. then flog one of them, 'cos i was looking on fleabay and they're listed at £100 + .... more pub money :-)
