Back into the shed this afternoon to do some more work on the bucket.
I wanted to make sure that while the rangefinder could rotate down towards the face of the bucket I didn't want it to be falling backwards if it came a little loose.
First thing I did was find a suitably sized nail and then drill a hole through the base of the rangefinder.

Then , with the rangefinder secured in the upright position I drilled through the hole in the base into the helmet. (Thanks eqdizzle for the idea for this

)


Then re-attached the rangefinder in the lowered position and again drilled another hole to mark the end point of the rotation.

With both holes drilled I then used the point of the nail to mark the arc between the two holes by holding it in while rotating the rangefinder.

I then drilled a few small holes along the path and gradually joined them together.

A little filing later and we have a channel for the metal peg (nail) to travel through which will prevent the rangefinder from rotating too far forward or back.

I then measured the length required and cut down the nail and glued it into the base of the rangefinder.

The next job was to see to the fixings for the visor. I'm following a method suggested by Pointoforigin.
Using the shortest chicago screws I could find and some scrap ABS from the armour trimmings ....

It's kind like making snap plates for TK's.

and then glued in place, the plastic plates should help hold the chicago screws in place as I wasn't confident that trying to glue the base of the screw to the helmet would hold.
So some glue, clamps and magnets later ....

I'll have to leave it until tomorrow to make sure the glue has set properly to see if it's going to work.
