Hey - those in #hand-tool-techniques may have seen my previous posts, but essential info:
I have a bronze LN 4. Worked great for a dozen sessions or so, then randomly while planing two sessions ago I felt like I wasn't getting good cuts or the blade wasn't adjusting correctly. The last time I uses it the blade was retracting after a few passes. I tried to adjust the lever cap, and after taking the blade out, inspecting it and playing with the distance between the CB and blade, I could no longer get the LC to stay down it would just pop up, and was incredibly easy to push down when I did get it to stay.
After talking to a lot of you, I decided to buy a new blade and chip breaker and threw the old blade and chip breaker on CIHI to recover some of the money. Several people there Dm'd me to tell me that prior to 1998, LN used a more curved CB with no etching and they claimed mine matches it. I looked up pictures and it appears it could be true. My main concern is to not spend the money on a new blade and CB if I then have the same issue.
Sorry for the book, but if anyone has any insight please throw it my way!
