For any that are interested I recorded router RPM at each setting today. These are all ball park as there are not detentes for the numbers and I rounded each to the nearest 50 1, 15500 2. 16750 3. 18750 4. 20650 5, 23200 6, 27000https://handibot.com/forum/read.php?2,529,529#msg-529Tue, 15 Sep 2026 15:02:22 -0400 Phorum 5.2.22 https://handibot.com/forum/read.php?2,529,542#msg-542 https://handibot.com/forum/read.php?2,529,542#msg-542
This is really a nifty little example of how much more accessible technology is to us these days ... and a pretty clever application of it on your part.

After getting the frequency we just multiply by 60 to get the RPM.]]> Mark Evans Handibot ForumTue, 08 Apr 2014 18:33:17 -0400 https://handibot.com/forum/read.php?2,529,538#msg-538 https://handibot.com/forum/read.php?2,529,538#msg-538
