Bought one of these last week to help repair some wooden window frames at Handyman Towers.
Stock removal is incredible with a 40 grit belt. Being only 13mm wide and about the same thickness it gets in anywhere.
Since used it to even up some lap joints on decking posts & sharpen my post hole digger.
Picture on the box shows it being used to open out the mortice for a door lock, can't wait to try that.
Dust collector actually works, belt tracking easy to adjust & stays tracked. Only downside is that there isn't a facility for adjusting the belt tension, so my 40 grit belt stretched a bit and stated to lose traction before it was worn out completely.
At under £40 a very useful bit of kit indeed.
