Bare Bones Bicycle Fork Jig

Step 11Done!

Done!
You're basically done! You can file a notch into the end of one the joinging plates and glue a small piece of tape measure to the short piece of extrusion to show how much fork offset the jig is set to. Don't forget that different steerer tube sizes will sit at different heights in the V-block so you will have to have one notch indicating the offset for each steerer tube size.

Otherwise, set your offset for 1 1/8 steerer tubes, and shim up your 1" steerer tubes to the same offset. Either use a piece of 1 1/8" x .058 tubing split in half lengthwise, or a piece of 1/16" thick flat stock folded over at 90 degrees, sized to sit in the V-block.
