In order to achieve a uniform clamping pressure on a small box I decided to use the Wolfcraft Band Clamp. However it did require some special additions to achieve the desired results.
One photo shows the components in the unclamped position. There are (4) wood corners; a riser under the clamp to center the clamp vertically on the box; and a “strap guide block” to help direct the clamping pressure of the strap.
The distance between the straps at the clamp body is 4-1/2”, a distance too close to the outside dimensions of the box. The “strap guide block” draws the straps to the center of the box thereby evenly distributing the clamping force around the entire box.
I have not used the supplied corners as yet. The projects on which I used the clamp I felt needed a longer contact area so as to distribute the clamping force more evenly on the box corners. Thus far I have made project specific wood corners. On the inside of the wood corners I used Epoxy glue to attach Plexiglas to help prevent any glue from the box contacting the wood corners.
I made a number of boxes with this set-up and they all came out good.
