Gun Sight for Blind Nailing

I often had trouble correctly placing an air-driven nail when the lower piece was hidden by the upper, such as attaching the roof of a bird house or a shelf on the inside of a cabinet. If I missed the edge of the inside piece, it could ruin the work. I solved this by creating this jig: Two equal length pieces of thin wood separated by a wood block, creating an opening large enough for the upper piece of wood. When I slide the jig over the

Formula Makes Picture Framing Easier

upper piece, the bottom part of the j ig is stopped by the lower piece and the upper part shows where to place the nail.

I have a great tip for making picture frames, which I figured out after messing up a few. I'm a do-it-yourself woodworker, and I know there are a bunch of us out there that build picture and mirror frames for around the house. Figuring out the outside dimension of the frame is always a little tricky.

This is an example of the formula that I've come up with to make framing easier. Stock width: 2"

Rabbet width: - V2"

Moulding width, less rabbet =1V2" Multiply by 2: x 2

Add this to picture dim. = 3"

Using Duct Tape for Easier Bent Laminations

Add this dimension (3") to the height and width of the picture to be framed. For an 8" x 10" picture, a 2"-wide frame moulding with a 1/2" rabbet, the outside dimensions should measure 11" x 13". And if the pieces are then mitered, you know the outside dimension lengths of your horizontal and vertical members.

While building an Arts & Crafts-style rocking chair with curved arms, back rails and rockers, I discovered another great use for the ubiquitous duct tape.

Anyone who has ever done any wood bending by laminating thin strips to achieve the desired thickness knows it can be a mess. Glue gets everywhere: on the finished faces of the piece, on the clamping cauls and on your jig. Aligning the pieces during clamping also can be a struggle. My answer to this sticky problem is duct tape.

When preparing for a glue up, I cover the face of my bending jig and my cauls with duct tape, to which glue does not stick. Glue squeeze-out inevitably gets on the outside faces of the top and bottom board and is very hard to remove from the curved surfaces without a lot of sanding and scraping, which can

leave the surface uneven. To prevent this problem, I also cover the outside faces of the top and bottom board of the lamination with the tape before gluing.

The last step before moving to the j ig after applying the glue and stacking the boards together is to wrap each end of the bundle with duct tape. This keeps them aligned during clamping.
