First I covered the shaft with masking tape and marked the mid point in the mirror shaft before taking the hacksaw to them
Now in half
I then held each half in a clamp and used the drill press to drill an 8.5mm hole in each half. I then tapped a 10mm thread into each
I used a 10mm bolt with the head cut off and made a spacer with some alloy tube from B&Q
Took a bit of positioning, but I then screwed them together really tight and used threadlock for studs on them
Cleaned them up and applied plastic padding
I slid on some 25mm heatshrink and shrunk it!
I will use some tyre black on the heatshrink as it is a bit grey - but still looks better than those mirror extender things. Time will tell if VTR vibration makes them fall apart, in which case I will get some R1 types after all!
