I own a beautiful no.7 plane made by juuma : it’s a copy of Lie Nielsen , that is a copy of Stanley bed rock pattern. It has a very good steel blade and comes from the factory almost square and flat: i need only 20 sweeps on 180 grit sandpaper to get it flat. The problem is..in the frog. i notice one screw, the left one slightly becomes less tight after few minutes of work and plane position changes in left 7 right axis…what could i do?
Could be poor machining of the threads. You might want to try some loctite thread lock or similar on the screw to see if it stays put.
Use the blue lock tight , put a small dab on the threads of the screw and let it dry before installing it .
My old mechanic teacher adviced us to use laquer for finger nails to lock bolts and/or nuts. Its dirt cheap, holds relatively well on most stuff, and comes off without too much trouble (acetone/nail laquer remover).
It’s less strong than lock fluids though, and likely to ruin paint/finishes.
If its a relatively new plane, I would ask the seller if he could fix it or replace it. Restoring old tools gives me a good feeling, but repairing new stuff with production faults just don’t get me there.
