first i wanna say i like how you did the earpiece. when i was making mine i didnt have the forethought to slice it beforehand. so i had to think up a way to do it after finishing. i decided to use bondo as a kind of cast. i covered the otherside with vasaline after cutting the bolt holes and slots for the nuts and resining them into place. then i appliedthe bondo and tightend the screws to cast the side. it works well and i cant see the crack so im happy lol










Hello again,
(firstly, this is quite a lengthy and wordy post, so if you're not in a reading mood, sorry)
Thank you, badfishman, Bobasbounty, and lord magneto for the kind words.
And crank, if youre excited to order one, im even more excited to see my work in the hands of another skilled builder to see what they do with it.
Now lets get down to it, just been working on the final ear cap, the one that cover the rang finder stalk pivot point, if that doesn't explain which i mean, stay tuned the the photographic evidence.
So i couldn't see a sturdy way or practical way for that matter how to attach this ear cap using the nut and bolt method i had previously used on the other ear caps so i went with magnets.
First, decide on the magnets, i chose wrong, but i think it will work for my first go. i went with some neodymium magnets which is really only ones to use, 4mm dia @ 1mm thick, they aren't quite enough strong though, didn't provide as much hold/pull as i had hoped for, which will explain the amount i used.

i had intended to just have two points on each ear cap, not the 5 i ended up with, but as i said, i wasn't happy with the amount of pull with just 2,3 or 4 points so decided on 5, which was lucky because as you can see i was running out of space.

Now i had the two parts of the ear cap attached, i went about attaching them to the helmet.
For this, i was only using a single nut and bolt to hold these in place, which is also the bolt that the range finder stalk pivots on.
Because of this it would not hold it's rotation, and could spin, so i decided to use dowel pins to lock in place.
First drilled the holes through the ear cap and test fitted the dowels.

Then lined it up where i wanted the ear cap and drilled through the helmet

I wasn't happy with the one on the right of the picture, so i drilled in the middle as well

That is just held in-place with the dowels.
Then bolted on, along with the outer cap held on with the magnets

You may have noticed the stalk isn't present in the above pictures, well there is a reason...

Haven't decided on how to resolve this yet, i have a few options though in mind.
Thank you for your attention, i'll let you go now.
