Thinking about adding digital indicators to your truing stand but not ready to dive into visualization just yet? This post contains pointers to digital indicators you can add to your truing stand so visualization is an option when the time comes.
Islandix Wheel Analytics interfaces with digital indicators that conform to the Mitutoyo Digimatic SPC standard. This entails the use of a special cable (included with Wheel Analytics) and a signalling protocol for transmitting data on the wire. This means you can’t go wrong with Mitutoyo indicators but the market is serviced by compatible brands too.
The whole Mitutoyo 543 range is a great choice. 543-5XX and 543-7XX models are my preference; specialty 543-3XX and 543-4XX models work too if you have them already. You’ll see lots of options with different feature combinations depending on your preferences. Say, for example, you want to replace your Park Tool analog indicators with Mitutoyo 543. Look for a model with 4-48 UNF threads, which lets you re-use the nice indicator tips from your Park Tool kit. The Park Tool truing stand attaches indicators using a lug back so pick a Mitutoyo model with this feature (all model numbers except those ending in ‘B’). Compatible indicators for this specification include 543-506, 543-507, 543-783, 543-792, 543-793 and 543-796 among others. All Mitutoyo products are premium quality and the least expensive are perfectly suitable for driving visualizations.
Other brands also implement the same standard, which means there are options at difference prices. The iGaging 35-705-10 and 35-700-10 have the same data interface but cost less (you get what you pay for). Both models use 4-48 UNF threads and both include lug backs, which make them drop in replacements for Park Tool analog indicators. Again the least expensive are suitable for driving visualizations.
