Well I have been thinking a lot
I got a Sony Action Cam and have been look at mounting it on my Tom I have tyred a few place's and been in a lot of pain thinking about it...... Well at last I have come up with the Best set up in the World
I got a Manfrotto 492 Ball head here.
I removed the bushing (down to 1/4")
Then tapped out the inside (which was 5mm) to M6
Here's the Tap
Then cleaned it, and fitted a bolt to check sizing
Then cut a bolt and fitted a nut and washer
And then fitted it in place of my old top cap and bolt
Then I mount up my Action Cam
How I can adjust it to not only be pointed out front but down to my front wheel, side way's, or back to my crank's/feet e.t.c.
Have a go
