|The Russell Jennings Mfg. Co auger bit box for their "Fig 100" bits (double thread lead screw)|
The box is 10 1/2" x 4" x 3 7/8" high and the walls and lid are 7/16" thick
|Underside of lid has the label. Top tier has bits #4 to 9 (1/4" to 9/16").|
Second tier has #10-13, bottom has #14-16.
|The box is put together with with box joints, each finger is about 5/32" wide|
|But note that there are three nails reinforcing each corner - one nail for each tier|
|The lid has a crack|
(At one time I sanded the lid, removing the patina. The horror!)
|Box bottom inset within carcase|
|Note the two nails holding the box bottom in place|
The hardware on this box is interesting. Each tier is secured to it neighbor with small clasps.
|Clasps on front of box - all work perfectly. They are attached with round-headed nails.|
It looks like the upper nails on the middle clasp are not original.
|The back of the box showing the hinges|
|Back portion of the three-knuckled hinges.|
Hinges affixed with round-headed screws (not "clocked" - an obvious faux pas).
|Where the hinge comes up on top of the lid, it is affixed by a single countersunk flat-head screw|
|First tier bits below the rim of that tier|
|Second tier bits higher than the rim of the tier|
|5/16" recess in underside of first tier|
|Third tier is similar, except the recess in the underside of tier 2 is only 1/4"|
|See the groove?|
|And this shows the underside of the middle tier and it's clear that it fits into a groove|
|One of the grooves can be seen from the outside of the box|
No matter which it is, there is a cross-grain situation in this connection. It certainly wouldn't need to be glued, but it seems solidly in place. There is plenty of room for the tray to expand and contract, as there is about 1/32" of space between the tray and the front/back of the box.
|An 0.029" shim fits between the tray and the back of the box|
|The saw kerf split the finger I'm pointing to|
|This was because the square tapered parts of the #4, #5 and #6 bits' shanks are too|
large to fit in their half-pipe compartments.
