I'v got problem with saddle tapered gib. Knee ways all scraped with 0.01mm between dovetails. Flat ways parallel. Saddle : gib opposite side scraped to knee with great contact. Gib angle checked by two dials to make sure it's lifting up same. All seems to be fited , but as visible on pic I can still lift up saddle 0.1mm doesn't matter how strong I'm pushing gib in pocket. What can be reason ? Gib Is shimmed with 0.5mm sheet. I'v noticed that gib and shimm are staying rigid with knee but saddle moves.
