This morning I walked over to see how progress on this new home was coming along. There was a large truck there at lunch time , but I could see what he has been doing.
I made a frame from 1x2 inch furring boards. Some came off the old curtain and I had one new board that I used. I build the frame on top of an old card table. I predrilled all of the holes and then counter sunk them so I could drive the screw deeper into stiles. I found some old white dirty six mill poly in house five. I attached to the frame with small straps of wood and with screws.
This photo is from yesterday to see the comparison of today's photo.
The is the finished look. I put on a pair of pipe clamps at the top twelve inches from each side. I then drilled two holes in a slight angle down. I put a cross brace which is black horizontal piece. I can lift the cover up or down to put or take it off the bolts.
Comments and questions are welcome.
