Do you want to build quality goggles made of metal instead of plastic or tin but you don't have access to a lathe ? Here is a set of 2 rims, precision machined from brass alloy, 2" outside diameter (52mm). suitable for 45mm round lenses (also included)
the lenses are optical quality grade, polycarbonate (anti shatter), suitable for outdoor activities, 100% UVA/UVB filtering, clear smoke tinted, made in France
other dimensions possible, email me for a request if you have a special project in mind. aluminium alloy rims can be made too.
