I created my own version of a guide rail parallel guide for repeatable cutting smaller stripes with a track saw.
For clamping I used M8x16 srew and nut.
Th rod is 12x1 aluminum form my local hardware store. I made them 500mm long which is suitable for my needs. Of course you can change it to any length suited for you.
For design I used onshape. If you need to change it for your own needs here are the model files:
Furthermore I added a knob for the screw head, which is not shown on the fotos.
The author marked this model as their own original creation.
