Helmet chin cup needed

[Rickyt]

Hi troops, where can I obtain a chin cup for the helmet? I've looked everywhere

I've got one if you'd like it.

What's the best way to attach the chin cup? Glue the bands to the inside of the helmet?

Get a strip of elastic, some snaps, and four 1x1" scraps of ABS. Cut two slits in the chin cup to accommodate the strap. Use the ABS to back the snaps on both the fabric side and the helmet side (this prevents them from pulling through the elastic and gives better purchase to the helmet). Put the button side of the snap on your strap--remembering to thread it through your chin strap--and glue the flat side of the snap (CA glue works well) to the inside of each cheek.

 

If you position the snaps right and get the length of the strap right, it'll apply gentle tension to help hold the helmet on without crushing your jaw. I suggest doing one cheek and the strap, then playing with the position/length until you're comfortable before gluing the second snap in place. Or you could go with a more complex adjustable slide if you really want.
