[QUOTE="Trickymissfit, post: 478678, member: 25383"] I built my own using a gauge pin, and the option to use a conventional gear & rack indicator or a wand type. Gear & rack indicators are well known for error built into them (most are rated at 10% lag). So if the indicator reverses direction in travel; your readings are probably flawed. Where as a typical wand type indicator is rated at about 3% for the cheap ones. An Interrapid or Brown & Sharpe Best Test are rated for zero lag in any position. Also most folks don't know that if you zero an indicator at the twelve o clock position, and rotate it to the six o clock position (upside down) the reading is flawed. There are some good gear & rack indicators that are rated in the 3% area. These will have a jewelled mechanism, and are not cheap. You can avoid much of this by using an electronic indicator, or simply buy an Interrapid that will do everything. gary [/QUOTE]
