Rail support

  • Pre-fabricated rail supports will be available for purchase separately from a kit.
  • Rail supports can be 3D printed (needs testing)
  • DIY rail supports are made from standard aluminum bar 1"x1/8". Make them from SVG templates, according to the instructions in Howto section. To mark the holes in the bar for 6-32 screws, clamp the bar with an angle piece in a vise as shown (pic__) and use 3/16" dia transfer punch touching the inner wall of the angle when punching. This will ensure that the holes are accurate. Todo: add pictures.



Gather parts. You will need one rail support piece for each 3" of rail length. 12" rail is shown here.
