hello and welcome to another video.today i am going top need to lift this pole up on my roof, there in my patioand so i need to make a lightweight and temporary sort of pulley.so let's make one. i am going to need a few bits and piecesa few tools and some materials of wood some scrap bits of timber now, you get a piece of timberof a reasonable thickness and more or less the size of the wheelthat you want in your pulley. then work out the center of thatby taking say, this distance that distance, and then goingcorner to corner to find the center.
roughly then cut that off then drill a hole down the middle of thator you can just whack a nail through but you do need a little bit of a holeso it will spin nicely in the pulley. and i am going to put it back on theremore or less. and put the nail through and nail it on there so that it will spin. and turning it over, so that nailis hanging over the edge i am going to cut the corners off. and then turn it and cut those little corners off too.
so there we are getting somethingsort of circular. now, if we want it more circularwe can put it in a vice. and use the saw to run on the top of thatboard and just trip up those little edges. if you want more precisionyou can get a hacksaw and go across those little lumpy bits sideways until you reach your guide board. and turn that around, and do that.and then finally you can use some sandpaper, to run that arounduntil you get it totally circular. if you are that perfectionist. and now to cut the groove in thereso that the rope will run in that.
take a thin piece of woodand but it up against there and with your saw, you want to run thatalong there, and go right around making a little guide cut. maybe about a millimeter or so deeplike that. and you want that to do that on both sidesso that you have got some guide lines here right around, so that you can nowput your saw on an angle maybe 45 degrees and cut from therefrom both sides if you do the angle correctly and you keep it even come from both sides
the cut should meet in the middle,then you are going to turn it and cut a bit more.using those guides as your starting point. now, to clean that up, put your saw thereand turn it sideways a little bit and just use your saw as a rasp and turn it the opposite directionjust to get those littler lumps and bumps out of it and get your curve going nicely. and if you are particular, you can use a round file and file it out a bit and maybe some sandpaper in thereif you want it really pretty. now, the next thing is the body,we are going to take a little block of wood
that is a little bit slightly thickerthan the pulley wheel and also a couple pieces of board.now if you are making a heavy duty one you want to use it a little bitthicker than this but mine is going to be light, soit is going to be, an assembly of that board, that therewith sufficient distance for the rope to pass throughand that on top, and nailed, those. and so there we have it nailed.they don't have to be strong nails because they are not what takes the weight. now, we are going to figure out wherethat's going to go. make a mark
more or less there, and with a squareyou can trasfer that to the other side so that we know where it is on this sideit's going to be central. and central obviously. and i can drill a pilot holefor the nail , on both sides. put that in, then i am going toput a nail through. now, if you want one more robustyou can use like a bolt. feed that through, then i am going to takea hacksaw blade or some thin onbject and put it in between there as a spacer and then with a hammer i am going to bend that over
if you have a bolt you are going to bolt it of course. then i am going to do a hole herefor my rope to tie it up to wherever i am going to put the pulley.the idea is that the rope that comes here transfers the weight to the pulley wheelthen to the nail to those boards. this here is reallyonly a spacer, it doesn't take any weight at all, because the rope goes through here and supports those two side piecesand takes the weight that way. so there we have it basically.we can trim those corners off we could put another block downthe other end for more stability
also i would put that maybedown here a little bit more if i was carrying heavier weightand make this block a little bit thicker as a result of that. now, here is the disclaimerand the warning this is only a lightweight pulleyand what you choose to lift with it is your responsibility.if you want to lift heavier things, make it more robust.all responsibility, is yours.
