Speedo trip reset shaft thread size?

[Matt_Harrington]

I now have my rather grubby Rev and Speedo slocks dismantled to the point where I can lavish a bit of care on them. The trip rod on my speedo is made of aluminium and is so badly corroded that is bends with ease. Does anyone know the size of the L/H thread that this attaches to the mechanism? 3mm x 0.5 x LH?? I may have some BA equivalents somewhere and so will knock up a s/steel rod to replace this corroded part once I have the size.

They are 3mm left hand thread

Thanks, Kent400. I have a 6BA l/h tap and will see if that works, if not, I'll source a 3mm one.

If the shaft is brass, then the 6BA is OK but too tight for s/steel, so I will order a M3x0.5 LH tap to do the job!
