Re: Picked up a Sonix Pro. Need some help
Does is hold air? Before I went to the extent of fixing the "indent" I'd check that first.
Beyond that, is the upper tube sill round? If you get rid of the indent is the bolt still gonna be able to move or will it get stuck still?
As far as getting rid of the indent, I'd start with a file to do the bulk of the work, then switch to fine grit sand paper to get it smooth.
