Digital File Only This file contains all the pieces to make the ramp and attached grind rail, two sizes of detachable grind rails and little connector pieces to connect the pieces together. (Other pieces sold separately.) This does require 1/8 inch wood and you make have to adjust the design depending on the exact size of your wood. The size I used was .125". The grind rails do have to be glued together and I sanded them to make them a little more round. The design includes Engrave, Score and cut lines. I have happy to help should you have any questions please ask I am happy to help. Chris Terms of use: - Digital assets are off limits.
