How to attach the liner to the SSH-36 helmet?
1. Rivet three rivets for the aluminum corrugation. Two of them are located on the sides of the helmet and fasten the helmet and chinstrap fittings at the same time. The third one is in the back.
To keep the rivet head round, you need to prepare the working surface (anvil): drill a recess according to the shape of the rivet head. Then connect the parts: rivet, helmet, mustache fasteners on the inside of the helmet. Before finally fixing everything, you need to check whether the mustache is optimally placed for attaching the corrugations. To do this, attach the corrugation with holes to the whiskers on the sides of the rivet and make sure that they are flush with the corrugation holes.
2. Attach the corrugation to the helmet. Connect its ends and "stick" the holes on the mustaches of the fasteners on the sides of the helmet. To do this, you need to bend the mustache in a U-shape. But before bending, attach the corrugation and adjust the distance under it at which the ends of the mustache will be bent (the width of the U-shape) so that the corrugation easily docks with the mounts and helmet without gaps. With the back mustache we fasten the corrugation with an overlap.
It happens that the corrugation as it is does not fit very tightly to the helmet when joining the holes. Then you can stretch it a little or even file to widen the holes in it. So that in the end the liner sits in the best way. After fastening, the corrugation can be slightly pressed against the helmet with your fingers.
3. Paint the helmet and fasteners. If the helmet is in good condition, and it is not planned to paint it, then you can pre-paint the corrugation separately. And after fastening all the details, carefully tint the rivets from the outside.
4. It remains to fix the soft part of the helmet. In places of fastening near the helmet, unsewn "pockets" are provided. It is necessary to attach the liner to the helmet, mark the places for the holes for the tips of the mustaches of the mount (so that the unsewn pockets cover the mounts). Holes should be made in pockets so that the fabric covers the pressed ends of the mustache.
And so that the fabric of the pocket does not interfere with making holes in the cardboard and the shock-absorbing sponge, yyou can put the open pocket on a handle or stick, fixing it firmly. And punch holes with a knife or a sharpened screwdriver. Now you can fix the liner by putting holes on the mustache of the fastening, unbend them to the sides and close the pocket fabric.
