Step 1: Parts and Tools List
1 - 1-3/8" PVC T Connector
1 - length of 5/8" wooden dowel
2 - flat washers
1 - 1/8" x 2" #6 machine screw
3 - #6 hex nuts
1 - Package of assorted tie wraps
(black paint - if desired)
(epoxy - optional)
Step 2: Shaping the T Connector
Once that was completed, I cut half of the length-wise section (opposite to the "T" protrusion). This provided the base section that is needed for the mount.
Next, cut a "slice" of the 5/8" dowel about 3/4" wide, this will be place in the top of the "T". It will be our extra "handlebar" space for mounting the Forerunner 305 bracket (See drawing in this Step).
Now you can drill the 1/8" holes in the dowel section and the PVC "T" (see drawing) to attached the dowel to the "T".
The last modification to the T connector are cutting two notches (~3/4) in the "T" protrusion for the Forerunner mounting bracket.
With the holes drilled, you'll insert the 1/8" bolt thru one side of the PVC, place a nut on the bolt, then a washer, the dowel, the other washer, another nut, then thru the other side of the PVC with a last nut on the end (see "top-down" drawing). Using the screwdriver and wrench to tighten the bolt and nuts against the dowel and sides of the PVC.
Once the parts are assembled, (including attaching the FR305 bracket to the dowel section of the mount with tie wraps) - you can use some epoxy to further secure the dowel to the PVC. I placed tape over the top of the "T" along side of the dowel and FR305 bracket. Then turned it upside down and applied the epoxy through the "bottom" inside of the "T". Allow the epoxy to cure completely before painting.
