the frame consist of six different wooden pieces,Two pieces sandwiched to together making up each of the two “pins”. And two pieces sandwiched to together with the lenses in between making up the main frame.



How to glue the pins:

Start by making a mold with the preferable curve, an example showed in pictures below, the width of the mold shod be about 60mm. Just cut a plank with a slight curve. When gluing you apply wood glue to bout pieces of wood, then hold them together to make the glue stick. But don’t use too much glue it might get very slippery when you apply the clamps. The clamps used are standard spring-loaded wood clamps. Start by applying a clamp on the flat end of the pins, try not to make the two pieces slip out of alignment. Then apply more clamps to secure the pieces firmly to the mold. Try to remove excess glue to prevent the wood form gluing to the mold.



Keep in mind the two pins needs to be mirror images of them self, so don’t make two with the same bend. What is really cool is that the pins naturally form a slight bend towards the end because of torsion stiffness of the wood, caused by the grain direction in the laminate.

Keep the pieces in the mold to the glue is fully dried 1-5 hours, depends on the glue used. Normal wood glue works great. The shape will then be permanent.

How to glue the main frame:

Start by making a mold with the preferable curve, an example showed in pictures below. When laminating the pieces with the lenses in between. Start by doing a dry test to see that everything fits correctly, the same goes to the pins.

The main frame consist of two different pieces

one 2.4 mm thick piece with a counter sink the same debt as the thickness of the lenses used, normally 0.4-1mm. see pictures below.

And one piece 1.8 mm thick without a countersink, see pictures. The outline of both shapes is added as a pdf.

If you are using a laser cutter you will need 3 pieces instead of two. The

third piece will have the same thickness as the lenses used. This piece will be sandwiched together in between two identical 1.8mm pieces whit a smaller diameter around the lenses, compared to the piece in the middle. See picture of the 1.8mm piece.

Make sure the “inside” of the frame is sanded smooth before proceeding to the gluing proses.

Add tape to the lenses to prevent glue from sticking and scratches to be formed. When gluing, make the 2.4mm piece with the counter sink the back piece and the flat piece the front piece of the frame. This order works best. Gluing of the frame is difficult alone, but simpler with a friend (recommended). Add glue to bout the pieces of wood, use as little glue as possible to prevent the pieces from slipping, and glue form spilling over the lenses. Normal wood glue can be scraped off the lenses quit easily. Place clamps to hold everything together.
