I thought you needed glass? The calipers aren't. But if stainless steel slides are OK you can get come pretty decent ones from both eBay and Amazon.con for just under $100. The best of this class are the AccuRemote for 8" you buy the 12" and cut it to size. Price is $62. The serial data format is known and there is open source code available to read it. The next step up are the absolute type. Also stainless for about $125. No sure if the serial data on these been reverse engineered yet. Also on Amazon.con are the accusize brand glass scales which claim .0002" and cost about $200 for the length you need. I'm putting the $62 type in my Harbor Freight mini-mill and will use a cheap $100 Android tablet as a remote wireless DRO display. -- Chris Albertson Redondo Beach, California ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
