The most critical quality control factor was the fit between the tenon and the mortise
. This variable was controlled by matching the drill used to bore the mortise
with the hole-saw used to cut the tenon.
Because of the potential contribution of shoulders to bending moment capacity, an exploratory study was undertaken in order to investigate the characteristics of the "shoulder" effect and, if possible, to develop a practical expression for estimating the bending moment capacity of round mortise
and tenon joints with shoulders.
King is using Sosman & Landis "half mortise
sheave for flats." What technology did other theatres in Columbus use that caused the scene changes to be so noisy?
(a) Full-scale model; (b) elevation of the full-scale model; (c) dissembled view of the bracket set; (d) dovetailed mortise
and tenon joint.
STEP 4: Mark the length of the mortises
in the stiles.
In general, joints with tenons 15 mm in width and without tenon shoulder failed as a result of fracture of the tenon, whereas joints with tenons 15 mm in width and with tenon shoulder failed as a result of glue-line fractures, splitting of the tenon and indentation of mortise
Inclusion of knee braces (with end tenons) into frames constructed with round mortise
and tenon joints can be difficult because the tenons on the ends of the knee braces along with the tenon on one of the members (usually a beam or post) must be inserted simultaneously into their associated mortises--a problem also encountered in conventional rectangular mortise
and tenon joint construction (Chappell 1983).
With the piece thus formed, I shaped the end corners to fit the stock trigger guard mortise
. A good eye with a steel buffing wheel, or even a flat file, will do well here.
The air flew from 10 mm--wide mortise
. The schematic layout of the air outlet towards the inclined wall is pictured in the Fig.
But there are also some very capable rim deadlocks that are recommended for doors that lack the thickness to fit a mortise
rack bolts are unobtrusive and extremely secure as they are fitted into the door and frame.
To avoid this, place a metal rod or piece of plywood in the track to prevent an intruder forcing the door open and fit mortise
bolts at the top and bottom.
