Step 1: Parts Needed
1 Used Leather Belt or Strap
1 Steel handlebars (the older the better)
10-32x2 Round Slotted Brass Machine bolts (2)
#10 Brass Finish Washers (4)
10-32 Lock Nuts (2)
Brass drywall screws (2)
Step 2: Tools Needed
7/32" Titanium Drill Bit,
Dremel cutting tool (or hacksaw),
Step 3: Preparing the Parts
Next make sure that the handlebars are clean, if they are stainless steel they will shine up nicely with some 0000 steel wool. Once shiny you can clear coat them to prevent oxidizing.
Step 4: Drilling the Handlebars
2) Make a mark on the top of the handlebar tube on each side.
3) Using a center punch, provide a starting point for your drill on both sides of the handlebar. Without a starting point the drill will naturally want to roll as it drills. If you don't have a center punch just start drilling slowly.
4) Drill all the way through the top of the handlebar and ensuring that the drill is level, continue drilling through the bottom portion of the tube. You should be able to see straight through the hole when done.
5) Repeat for the other side.
