Hi I am currently building my first dio, I am A person who likes everything to look to the best of my abilities. I Know how to make the weapon slings myself or I have got some from manufactures online, My question is how to attach the Slings to the rifle butts and towards the end at the barrel.
Do you just glue them or attach a peice of wire first then attach the Sling Please if anybody knows Any ideas it would be greatfull and the more Ideas the better I have looked threw lots of photos from other dios but none really let you get a good look at the attachment points. Any, And I mean Any advice I will be very thankfull.

My process is this
Cut the sling from foil from a wine bottle or yogurt peal back lid or tape. Cut it a bit long to accomodate fold overs on both ends. Don't forget to add extra for the 'slack'.
Cut a small 4mm to 6mm long piece or wire.
Wrap it around a pair of square end pliers to make a buckle loop - make it wide enough to fit the sling through.
Stick the end of the sling through the hole, fold it over 1-2mm then super glue (CA) the strap back over the buckle on onto itself.
Then repeat at the other end - adjust the length for the slack end.
Then I roughly bend the sling to it's position in the diorama and superglue the buckle to the weapon.

I don't have any really good photos - here's one you can kinda make out the buckle at the top, the slack at the bottom, the buckle at the bottom. It's lareger scale, but my process is the same.

The strap on the gas mask container is the same basic process

One more from me
Check out this review - there are two photos that show the straps a bit.
Review

Most modern weapon slings utilize what's called a three bar slider. (generally more than one) It's nothing more than a piece of flat plate with two slits parallel to one another.

They're very simple to make:

Sandwich a strip of .010 styrene between two Plastruct channels of the same width and cement with liquid cement. After it's dry you can slice off as many as you like, as thin as you like. Change the spacing in the slots by changing the angle of your cuts. Way cheaper than photo etch.

I use masking tape.
Take a strip and apply it to a piece of glass,then paint the one side to your desired color.
Next,using a ruler and a sharp Xacto kife,cut in the widths you need.
Using the knife gently lift one end and pull the section off.
Again stick it to the glass and cut at the length you need.Use the underside to apply it to the gun stock and run it where you need it,i.e around shoulders.The sticky side will hold it in place until you have it were you need it.At this point add a small drop of glue to where ever it connects to the gun,figure etc.
When dry,piant any of the underside that shows.
Also works well for equipment tie downs.

do you have any diagrams or photos of this proceedure?
