What kind of belt should I make

[Camano Ridge]

Skeeter, this should answer your question. The buckle is attached to one side of the buckle, the loop to the other side. THere is a hook on the back of the buckle that hooks in to the metal loop on the other side.

I want to make something like this with 4" wide belt with 1 1/2" billets
the wider belt will provide a little back support.

Thanks, Camano.

Thanks for all your comments.

If you want back support have you looked at the mounted rigs.  They have some other features, but they do have back support.
