This is the micro-adjuster I made for the fence on my ELU TGS173 flip-saw (Equivalent to the
DeWalt DW743). Its made from a few small off-cuts of Oak, two M6 roof bolts ( M6 means a 6mm thread with 1mm thread pitch, about 1/4”), an M6×25mm (1”) repair washer, a regular M6 washer, three M6 nuts, a small piece of 120grit paper(yellow in the picture) and a locking lever.
Pic 1 shows the assembly from the adjustment wheel end ( the large repair washer ).
Pic 2 shows it from the threading end. The small block to the left of the main body is pulled tight against the table edge. As the table is folded steel this only has to grip onto 3mm (1/8”) of steel and is held tight by the black locking lever (with the red top).
Pic 3 shows it in place on the saw, The adjustment wheel has ten notches cut around its circumference (I later numbered these for easier reference). This wheel is attached to the main adjustment screw. On the top of the main body is the reference line and two wood screws, one cross head one slotted. These are used to remind me if I’m adding to the blade/fence distance or making it smaller ( + or – ), it can do both.
Pic 4 shows the M6 tapped hole I made in the fence to take the main adjusting bolt. The main adjusting bolt screws into the fence stock.
Pic 5 is the sawyers eye view
As the thread pitch on an M6 bolt is 1mm, each tenth of a rotation on the main adjusting wheel is 0.1mm or about 4 thousandths of an inch. with the adjuster locked to the saw table and the fence just loose I have a range of about 35mm (1 1/4”) over which I can adjust to 0.1mm before I have to move the adjuster.
It cost pennies. I figure if it breaks I’ll just make another. I’ve been using this one for five years now.
