In this video I build a small picture frame from MDF. Because of the shape of the mitre sledge, it is difficult to create a pre determined measuring system to help position the flip-stops. This is because the thickness of the moulding effect where the measurement is taken. I measured and cut corresponding side by eye, gradually moving the flip stop until I was happy with the rebate matching the pre-bought matting.
I cut the rebate using the table-saw, however I could have also used my router table for a better finish. I may have also painted the moulding before cutting the mitres, but I would only do this if I was making a large number of frames.
I use a simple homemade four corner mitre clamp to assemble the frame: http://youtu.be/LCXvVVh8bvw – In retrospect I should have glued and vee-nailed each corner before clamping. This would have allowed the glue to dry while being kept in place. It is not necessary to have an air powered wedge/vee nailer – over the top – and I only have one because I bought mine second hand. A simple wedge pusher will suffice.
Painting the surfaces I applied a primer first, allowed to dry before sanding with fine grit paper, and undercoating. Each additional level of top coat should be sanded between coats depending on the type of finish you desire. Painting the moulding with a roller before cutting and assembling will produce a better finish.
To cut the glass I used a t-square – http://youtu.be/c7Pa6DvR4dM – to guide my scoring, and apply cutting oil to the glass scorer. Always try to score once, in a smooth action and use a thin piece of dowel to rest the glass upon when snapping. Compressed air is used to clean the glass and matting before everything is assembled. The back board is attached with a framing point inserts tool, although simple pine nails could be used , after which brown tape is used to seal the edges.
