A Swing Bridge instead of a Duck Under

[ngauger]

Now - you can attach the bridge. Place the framework in the opening.

If you are using the Horizontal 2 X 4 as the base - you should have the 2 X 4 even with the layout height.

If not; set the height 3/4" (Thickness of 1 X6) below the level of the layout. You can use scrap wood under the vertical support to rest it on. line the vertical 2 X 4 up with the support and screw ONE SCREW through the top hinge. This will take the weight off and let you let go so you can align everything. Put a second screw through the top hole of the bottom hinge.

It should swing out very smoothly and you should have a space between the end of the horizontal 2 X 4 and that alignment block.

Open it & get the 1 X 6 and cut it to the length of the opening above the closed bridge:
Lay it on the layout edges, across the opening, and mark it underneath, along the edge of each end of the layout. "cut it right along these lines"...

This will give you a board that should drop right in and lay on the frame you built (close the bridge again). It should fit just a bit loose. When you drop it in - inspect BOTH ends - this new board should be level with both ends of the layout.

It should be a smooth transition from bridge to layout on both ends. If it is - You re fine - if not - you will have to raise up either end of the layout with shims under the legs or re-attach the hinges. Remember - you can also glue a shim to the bottom of the 1 X 6 at the "Opening" end as I did above.

Once you have it level - Attach it to that horizontal support 2 X 4 with screws. Then screw the rest of the hinge screws in. AFTER you have attached and aligned the 1 X 6 again!!!!!

Then try to open it.. It won't open - because you need to cut it.. Get a wood saw - or hack saw (takes longer)..and cut as shown below. (red line).
