String Height on a Lap Steel

Height off the neck 

One thing to remember – Perspective affects intonation. 

The further away the strings are the less accurate your placement will appear therefore the more adjustments with ones hand are necessary until your ear/tuner tells you your on the right notes. 

Doubt me. Think little of it. Do a simple major chord then do a forward or reverse slant. How sharp or flat do you have to place the tone bar/Steel bar to achieve the right note during your slant. 

Perspective is everything. 

Just my experience. 

1. so I set it up close enough for this to not cause a major issue. 
2. Also consider your pickup and how near/far your strings are at the bridge side above your pickup. Don’t make the angle between the nut and the bridge too steep as this is counterintuitive for efficient playing.,

My current setup is:  At the nut: 8mm is 5/16th inch. and  at the bridge: 10 mm is 3/8ths inch
