Hi everyone I have 2 questions. Any help would be appreciated.
Q1: I need some sort of protective layer that will have as little friction as possible for the ball bearings to roll on. Ive heard of spray on varnish which I'd like to opt for but have no idea what sort of matt or satin or product to opt for. Main concern is that the final surface needs to be smooth and not grippy as much as possible. Looking to only have a light tint to the wood, nothing to dark.
Q2: Tool?? I've seen tools that could cut, drill and sand hand held and easy to manuver but not sure what they are.? As have alot of fiddly angles, small adjustments sanding and cuts to make this would be handy. For this project I need several of 4 different cut shape types out of 3mm Mdf for doors and windows at final stages. (see photos) I bought a jigsaw and know I could use that and a holesaw but is there a tool that could make this easier for me than that as I'm pretty confident with a steady hand for something hand held and easier to manuver that I can use for a broad range of tasks.
