Bought this a couple of years ago thinking I was going to use it heaps. Turns out that wasn't the case and it's been sitting around gathering dust since then.
Yours for £50 (£75 on Wiggle). Collection Shoreditch/Dalston preferred, but I can also post.
Here's the official description:
Designed especially for the home mechanic, the TS-8 allows accurate wheel truing at an economical price. Accepts wheels from 16" to 29", with or without the tire mounted. Innovative sliding dropout allows quick wheel installation, no matter what the hub width (up to 170mm). Dishing (centering) is performed by simply flipping the wheel in the stand. Constructed from heavy gauge steel to resist flexing, the TS-8 can be used freestanding or bolted to a bench for extra stability.
