Twin-Pin Board Edge Center Marker
Two 6 mm steel dowel pins press into 6.05 mm bores 100 mm apart, with a pencil clamped exactly halfway between them. Set the pins on either face of a board up to 94 mm thick, twist until both pins touch, and slide it along to draw a true centre line. The 8.2 mm pencil bore has a 2.5 mm split and an M3 pinch screw with a captured nut, so it grips pencils from about 7.4 to 8.2 mm. The bar is 120 x 24 x 12 mm.
1:6 And 1:8 Dovetail Marking Gauge
A two-ratio dovetail marker. A 10 x 14 mm centre fence hooks over the board edge, and one of two trapezoid blades lies flat on the face. The 1:6 blade suits softwood and the 1:8 blade suits hardwood; both edges of each blade are at that ratio, so you can mark tails leaning either way without flipping the gauge. It measures 90 x 120 mm overall, the blades are 3 mm thick and 80 mm wide at the fence, and each blade has a 6 mm hang hole.
Nine-Offset Pencil Scribing Gauge
A 150 x 55 mm flat scribing plate for marking cabinets, countertops, shelves and trim to fit wavy walls and floors. Ride its straight edge along the wall and trace a line 5, 8, 10, 12, 15, 20, 25, 30 or 40 mm away. Each station is a 60° cone ending in a 2.4 mm hole, so the point of any sharpened pencil (standard or carpenter's) settles on the same exact line. A 16 mm tall rib along the back works as a grip and keeps the plate from flexing.
Pipe And Dowel Straight-Line Marking Saddle
This 120 mm inverted 90° V-saddle sits on any round stock from about 8 to 40 mm OD, including 8 mm rod, dowels, 1/2–3/4 in EMT and 1/2–1 in Sch 40 PVC (21.3 / 26.7 / 33.4 mm). Because the V always centres itself, a pencil run through the 100 mm slot at the apex draws a line exactly along the top of the tube. Rim ticks every 10 mm let you mark evenly spaced, in-line drill points for drip manifolds, dowel pins or cross-bolt holes.
Four-Radius Corner Rounding Template
A 100 x 100 x 4 mm hooked template with a different corner on each side: 1/4 in (6.35 mm), 1/2 in (12.7 mm), 3/4 in (19.05 mm) and 1 in (25.4 mm). Hook the 6 mm fence lips over the corner of a board or panel, then trace or flush-trim the arc so every corner of a shelf, lid or plate comes out the same. Through-holes next to each corner (one dot for the smallest radius, four for the largest) tell you which radius you're on.
Sliding Fence Marking Gauge
A print-in-place woodworking marking gauge: a 150 mm trapezoidal (dovetail) beam with a sliding fence captured around it, locked by an M4 screw into a heat-set insert (5.5 mm bore, 8 mm deep) that clamps down on the beam. Fence is 44 x 22 x 24 mm and sets the scribe distance from 22 to 140 mm; an M3 grub or pointed screw self-taps into the 2.6 mm hole at the beam end to act as the pin, and a 90 degree V-notch in the fence face lets the same gauge ride round stock to scribe a dowel or pipe centerline.
