if yer out skating and an axle nut goes kaput and you cant get it on/nobody has a spare/etc you can take a few pull tabs from a soda/beer/etc can and mangle it around the axle so you can atleast skate for the rest of the session. i have a friend who swears by putting stickers under baseplates because it """prevents pressure cracks""" - not sure how true that is apparently its from some koston setup video. tiny wax/candle shavings on bushings/in pivot cups stop the squeaking (i mean tiny amounts of wax), if you wanna loosen em up you can boil bushings too. always check your mounting bolts periodically so you dont fuck up the baseplates, if your mounting bolts on top get threaded (phillips/allen whatever) try folding some paper and putting it over the bolt then sticking the allen key in - just like prom night theres alot of blind poking until you find the hole but eventually it fits nice and tight. everytime you get a new deck (every 2/3 months for me) stick all your bearings in a bottle, fill it with citrus based cleaner thats covering the bearings and shake it for a bit, let it settle, shake again then drain, clean them off with a baby wipe or some shit, dry and lube em with speed cream or whatever you wanna use. look after your board and your board will probably make you eat shit as they are unsentinent wooden toys with no regard for your safety but it's nice to maintain your board.
