[CAUT] New Renner underlever system

[Jim Busby]

List,

I might point out that Rick says the picture on the Renner site shows the posts flipped BACK, but Rick says they should be forward.

List,

A "duh" moment... (Rick Baldassin is close by and he helped write the manual. Probably should have consulted him first.)

I called Rick and he says to measure the grams "with the underlever horizontal and the posts tipped forward".  Luckily this is how I have (inadvertently) been doing it.

As I tried several methods it came out quite different. Posts tipped backwards = about 2 grams less. At rest vs. horizontal = about 4 grams difference. Rick says this will make a big difference in the touch and that using the grams recommended in the manual should give the best outcome.

Use a scale under the tray with the tray on blocks if you don't have the right gauge.
