morning guys I'm Dave Canterbury with the Pathfinder school and what we're going to do this morning is another project in our green woodworking series and we are working on small projects as we go and working up in complexity and working with different types of wood to make different projects with the hand tools that we've selected and now that we have honors we can bore holes so the next tool that we're going to make the next wooden tool we're going to make is going to be a simple wooden pulley system we're going to make a pair of pulleys so that we can compound the leverage that we have on these pulleys so that we can cut the weight in half of something that we're trying to lift with these pulleys if we have one pulley in the system and the Rope is tied directly to an object that we're lifting up you're actually lifting the same amount of weight with this rope but what that allows you to do is pull your force downward and it helps lift that weight up and does not displace any of the weight or change the amount of weight that you're pulling with the rope because you've only got one pulley however if you add a second pulley to the system one connected to a solid object and one connected from the bottom to the object you're trying to lift you cut the weight that you're trying to pull in half so we're going to make a pair of these wooden pulleys today I'm gonna show you how to make them it's very very simple it takes very limited tools to make them and I'm gonna show you a special knot that you use to set this pulley up so that you don't have to enclose this pulley and put any kind of framing on it you can just use the axle itself and the pulley and it will work very simply with a special knot called a cat's paw in your rope stay with me okay so let's discuss a few things here real fast before we get started because what we're going to do is the two components that we're going to make is we're going to make the pulley itself in the axle and we're going to make the axle out of hardwood and we're going to make the pulley out of the softer wood for right now for this project and we've got a piece of poplar here and a piece of ash okay so we're going to use ash on the inside or axl which will make it nice and strong and then raise a softer wood for a pulley which will make it easy to carve okay

what I've done is I've just taken a piece of stock here that I've cut off and I've drawn a line around it with a marker you could use your knife blade or whatever score that line just to give me a guide of where I want to put my knotch like this one okay we'll be right there in that line so these will be these pulleys will be about the same size when I'm finished now let's set those aside for a minute we're going to use our full advice again today to hold our material while we're working on it and the split vise is very good for a lot of these smaller projects you're going to want to match your kit to the projects that you plan to work on one of the main tools that we're gonna use today that I'm going to show you work to make this cut out is going to be a fro and a fro can be a very precision tool if it's used correctly and if you have the right fro now this fro is one that I recently purchased I had this made by Brad Holman at Holman blacksmithing and he charged me $30 for this fro now you just use an old broken shovel handle on the inside of it and it works out perfect but this is a major-league throw this thing is made for living things like shingles or splits and slats for boats or the side of a building and things like that this would not be something you'd want to use too much for small projects because it just has a lot of beef to it but it's great for those bigger projects so when you're building your kit decide on those types of things and maybe you want more than one fro and for me I've made this fro about two or three years ago from a horseshoe rasp and this pros lasted me a long time you can see that it's much shorter it's also much lighter and it's much thinner but this pro will do a lot of fine tasks that I might not want to use my knife for and it will also rib finer materials like for basket making or chair seat weaving and things like that you can rib those finer materials with this fro a little easier than you can with this and afro is not just a splitting tool you have to understand that the purpose for this furrow is for splitting and then levering or what levering those pieces to split something down along its grain this is not something that's just made for cutting splits off firewood and things like that it's actually made to split things down the grain by opening them up once the furrow is inside of them you can also use your throat to do quite a bit of certain carving tasks that are very simple and that's what we're going to do today so what we're gonna do is we're gonna take our stock and we're just gonna put it in our vise right here in front of us and I'll try to kind of get this to where you guys can see it if I have to I'll move the camera and you can see that nail is holding this where it needs to be and then I can put my foot in the other end just like this and all I have to do is rest my foot down there and it's gonna hold that stock right where I want it okay now all I'm gonna do is come in here and first of all score line with my smaller mallet and my smaller fro so I'm just gonna walk this line and try to get an equal cut around this piece so good - good taps all the way around scoring that line

and I'm back to the beginning now now once I have that line scored around my piece I'm just going to cut a wedge out of this thing on both sides so I'll start on one side and go around start on the other side we're gonna make a beaver chew how this thing it's gonna look just like a tree that a beavers been chewing on when we're done and then we'll smooth it up with the throw in the end and we'll move this camera so you can see a little bit

so I'm just gonna come in here at an angle I need to move my workpiece out a little bit I can't easy enough I'm gonna come in here at about a 45 degree angle and she right into that wine this is the beauty of a small fro like this is you can manipulate it real easy to get what you want you're not beating on your knife for no reason although you could use your knife for this in an emergency you could use your knife for this no problem but if you've got the fro you don't need to risk using your knife now get to the other side manipulate things a little bit just like this come in from the other side use your mallet now we're gonna get those chips are gonna get knocked out of there that would just make

now we're just gonna come in here and everywhere you see these use that we've put in here now we're just gonna come in here and clean those with our fro just like that we could get it from both sides we can turn the work around to get the other side again so we'll just go around this one first get those chips shoes out of there all those little use where that point is again I reck I relate a lot of this stuff to napping stone because there's a lot of building platforms that you're going to use for your next stroke and things like that just like when you're napping flint every time you take out a chip you've created some type of platform a ridge for the next one it's the same thing with this so now we're gonna come in here and get the other side and a smaller fro like this you can really manipulate it and use it or a carving tool you can do this same thing with a chisel but we haven't added a chisel to our kit yet so we're trying to see all the things that we can do with the tools that we have and only use new tools or add new tools when the necessity dictates it after we build our kit I'm just kind of going through here clean it up any last-minute chips out of there

that's not too bad okay and it doesn't have to be absolutely perfect you're just gonna be riding rope in there and the Rope will wear it down as it goes as well especially with the softwood now we have the makings of our pulley we have this part completed now we need to cut it off the same length as this one and bore a hole into it on Center with an auger

okay so boring a hole in this thing what we're gonna do is I'm going to take this and bury it in the stump just like this and that's gonna create a fence we're going to put this piece up against that fence and slide a wedge in here to raise this piece up right into the indention just like that and then we're gonna stand on it just like we did any other time with the foot vise put that thing just like that and that's gonna hold it still for us so that we can order out our hole the rest of the way okay at this point is just turning this into this which means you've got some carving to do you just start taking it off use those power strokes pull meat off of that thing faceted all the way around and knock the facets down and do it round just go a little at a time till you get what you need you get this side knock down ways you can start knocking meat off the other side all right so once you got your pegs cut down it's just a matter of putting them in evenly

I don't mind it it's a little bit tapered on one side and tight I just give me a better hole this one's pretty tight going in see what pretty even now some of the bark came off of this one while we were messing with it that's really not a big deal that bark doesn't need to be there anyway we could share cut the rest that off of there or just chip it off and not work too much about it if we're trying to keep up appearances

otherwise we usually call falls off really doesn't really matter for uniforms sake I'm just going to cut it off with this one and leave it on the other one the other one the bark didn't ship off of it at all this piece of wood was probably a little drier okay now we've got our two pulleys they're two different sized ones a little bigger in the other one that's not a big deal either the grooves are about the same size and we can dress these grooves up anytime we want to we can come here with a knife and dress these grooves up or we can come back in with the fro address these grooves up if you got a spot you don't like a spot right there I saw in the end I didn't really like I'm just gonna come in here with it don't push it shear that off and your rope is gonna wear that groove in there anyway as you go probably all right so there's our two pulleys now let's talk about how to set these up as pulleys to use them alright I'm gonna try to keep this camera pretty tight on this so you can see it all I got was a loop of rope here about a foot long and I'm gonna fold it over on itself as if I were making a larks head knot like this that would be a larks head knot okay but I'm not gonna make a larks head knot what I'm gonna do is I'm gonna take each one of these butterfly wings here and I'm gonna twist them three times or four it really doesn't matter I just want this fairly tight at the bottom and I'm going to put my loop through that then I'm gonna come over here I'm going to torch this one the same direction and the same number of times and put it over the top like that and if I've got them twisted even when I pull on it it should be evened up if it's not I've got more twists in one side than the other okay there we go that's what I want right there now this is going to let my pulley run inside this rope just like this we're not doing anything high-speed so you don't have to worry about wearing through the road because we're doing something at high revolutions we're doing slow pulling once we have that tied in and we're satisfied with that we've got an area right here between our not our cat's paw which is what this knots call is a cat's paw we've got a space between that cat's paw or up or not right here we've got to stop knots tied at the top and we would trap a jam knot right here from the top of bottom that was tied to either what we were lifting up to or what we're using at the top and what we're lifting from the bottom depending on where this pulley is station so up here at the top I've just got a jam not tied in here I'm gonna come in and connect that right there between exactly we're talking about right there 220 everything between the cat's paw and or not and that becomes our pulley all right and we pull down on that it's gonna hold friction right here in the cat's paw you're gonna give us our U and this and that's gonna trap or pulley on the axle just like that all right now let's put our second one on something that we're gonna lift okay so now we have 125 pound anvil sitting here on a 4x4 stand so you got a couple hundred pounds sitting there with a chain wrapped around it I have one pulley that is attached to that anvil here in the center lot of cat's paw here jammed out here this rope is doubled over so it's time to top it comes down through this pulley goes up and goes through the pulley that we have at the top right here I hope I got that the camera I think I did raise out just a little bit see ya now we have compounded the leverage for lifting so at this point we should be able to step off to the side make sure our pulleys are in line everything is taut and even okay guys I'm Dave Canterbury at the Pathfinder school and hope you enjoyed this simple project today and the green woodworking something that you can do very easily all you have to have as a single auger bit and your kit and you can replicate this easy enough with just your saw in your knife and it will help you lift loads that may otherwise prove to be difficult appreciate your views I appreciate your support I thank you for thing you do for our school for our family or for business all of our sponsors and structures affiliates and friends and I'll be back with another video as soon as I can thanks guys
