There have been a few questions about the tablet setup shown at MADE and on Instagram. If you have a tablet in your shop, as many do for Di2 setup, dock it at your truing stand and have it work double duty.
How to make one? Browse photography accessories to find a holder that fits your tablet. The Islandix tablet is an older iPad mounted with an AliExpress tablet holder. The holder is fixed to the truing stand using an AliExpress clamp with articulating arm. The install required no modification to the Park Tool truing stand and doesn’t rely on pre-drilled holes.
