Jig for transferring the exact length and end angles to a new stair cap.
2 - 1/4" x 1 1/2" Hex head bolts
2 - 1/4" x 1 1/2" Flat head bolts (countersunk)
4 - 1/4" Wing nuts
4 - 1/4" Flat washers
1 - piece of lumber cut to fit jig (~10mm x 20mm)
I cut this on my table saw, shaving slightly until a perfect fit
Length is determined by the width of staircase - I cut mine so the jig was centered on
the adjustment when in place on stair tread.
The holes in the lumber for the countersunk bolts are drilled slightly undersized so
the bolt "threads" into the board.
Ever tried to layout 'enclosed' staircase treads????
Decided to build my own stair tread caps. First measure and fit went pretty good, but not as good as I wanted. Thought there must be a tool for this job and searched online. After looking a few designs over I choose to design and print my own rather than drop $100 to $150 on a commercially available one.
