I just wanted to share how my 4" inch half-pipe PVC board hangers came out…
It is a simple concept. Take a 4" inch diameter PVC pipe (see how the 100 mm MBS wheels fit the pipe with precision ), cut it to desire length per your board’s wheel to wheel width; then slice the pipe all down its length; drill two 3/8 of an inch holes at the half mid section; two smaller 3/16 of an inch holes separated 1/2 and 1-1/4 of an inch from the edge respectively; with a saw cut a square out PVC section following the two larger holes contours (this will allow for the truck, bushings and kingpin to fit in when you hang the board).
P.S.: Don’t give me much credit because I copied the idea from this site…
