Making a Bladeless Wooden Fan - Scrapwood Challenge ep38

Scrapwood Challenge Scrapwood Challenge it's scrap, it's crap, it's firewood but some of the wood is good I'll start by picking out and preparing the wood pretty much like I do in most scrap wood challenges and while I'm preparing that wood I'll tell you about the project I'm going try and make a bladeless fan I'm very unsure how it will go and I'm not confident at all but it should be a fun project either way and I reckon it definitely lives up to the challenge part of the scrap wood challenge and by the way for those that are still asking the wood is camphor Laurel and it was given to me by a local business that make chopping boards I'm going to make the fan with segmented turning I've only done that once before that was a while back that one turned out pretty good so hopefully this one will work out okay too and hopefully the fan actually works if it doesn't then I'll end up with an interesting looking ornament I need to make three different size rings and I used an online calculator to work out the dimensions of each segment to cut the segments I'll use my wedgie sled on the table saw as that does a very accurate job these smaller rings will make the base of the fan and now I need to cut more segments for a coupler bigger rings the base rings have 6 segments but the other rings have 18 so after changing the angle on the sled I did a test with some old pine to make sure it's accurate before cutting the rest of the segments I'm using this loop made of bungee cord just to hold the pieces together while I put a couple of rubber bands on I've just turned these plywood discs on the lathe and they're going to be for mounting the rings onto the lathe but for now I'm going to use them to help clamp the rings together while the glue sets as expected the rings are moving around when applying pressure but I keep checking and adjusting until they take to each other please don't tell me about using salt to stop them moving as it's easy enough to do this without and I'll save the salt for my dinner now I'm ready to start turning but I'll quickly tell you what these pieces are and how they'll work hopefully how they'll work anyway this piece at the bottom is the base that will house a small fan that will push air up and into this ring here this is an outer ring and this one here will fit inside that will be the inner ring between the two there'll be a void and as the air pushes up and fills that void it'll get forced out of a slit at the back and the air should come through and we should have a fan fingers crossed anyway but at the moment I'm not that confident but we'll give it a go the one ends unfinished and there's a bit of a lip left on there but that's okay because we still need to shape that end for the other rings to fit on to now I need to make templates to help shape the rings and give those voids some good airflow that's the outside just about turned now it starts to get tricky I've got to turn the inside and I need to use this template here and if you look I've got to turn back in behind here I haven't got a tool to do that so I'm going to remove some of the material and then I'm going to reverse this on the chuck and work from the other side I've removed most of the material and going back to the template you can see that the front of the rim is thicker than the rest of it so I've already turned that down to the correct thicknesses now I need to get in there and do this little pointy bit here and to do that I'm going to use this diamond tool that's all done apart from the inside of that back section now that it's turned over we can see exactly where I've got a hollow out that last bit and just to show you on here it's this inside bit of the outside ring it's the next day and I've mounted the inner ring on the lathe ready to turn I need to get a good fit between the two rings but only at this end where they join where this rim is because this end is lower when it gets shaped I can start tapering this now and I can keep testing it and get this ring a nice tight fit up there up there and then I can use my template and finish the shape afterwards the inner ring is too deep it's bottoming out on the outer ring so I just need to take off around about 10mm I'm confident with a good push that will fit all the way so I'll call it done and I'll start shaping it the slit at the back is looking good it looks even and that's where the air will come from if it goes to plan I'm just going to turn the front of the two rings with them held together with that tight fit and I think that should work out fine I won't be gluing the two rings together so I'll still be able to access the fan later on and because of that I'm sanding the rim of the inner ring which will leave a set back detail rather than trying to get them flush I really like it and I reckon it looks better anyway removing the hot glue wasn't too difficult at all and it only took a few minutes now I need to fit the rings to the base and I use Sketchup to work out where to make the cuts I did that by intersecting two cylinders and then I took the base unfolded it and then printed it out to scale I was just going to go for it with trial and error but this way will get me close straight off I was going to cut this out with a coping saw because I didn't have the right size hole saw or forstner bit then I remembered I've got a really cheap set of hole saws and one in there was the perfect size as I started to drill it I realized I was going to go through part of the rim on the inside I didn't want to do that so by rocking it I managed and it worked out fine the fan will need to be able to pull air into it so the next thing is to cut some air intake holes into the base I could easily drill a series of holes and that would work but I think it's for the look I played with many different ideas including this cardboard mock-up I've decided I want to make a series of slots I think that would look great but it isn't the easiest thing to do so I've made this jig it took me about an hour to make and hopefully it should work I used a couple of dabs of hot glue to hold the guide in place I made a mistake the ends of those slots don't line up it was my fault I was careless I put this block in here to purposely put the base of the router up against and I didn't do that it was over by a few millimeters I can redo this end now it's set right the other end luckily that's the back of the fan so I can glue a little bit in there and try tidy it up I bought this fan just to use in this project and for its size it has pretty good specs as far as I could see but if it doesn't work well enough I'll look into using a computer fan instead it had heaps of good reviews and because I'm pretty useless at electrics this was an easy way to go it has everything I need the fan speed selector and also it's rechargeable too all I need to do is take the parts and rearrange them inside my fan which I think it's something even I can do first I'll cut out and make a panel with the buttons there wasn't enough material to make it into a rectangle I could have made a new panel but I thought it looked fine as it was the sides of the opening are slightly tapered so it's wedged in there pretty well and I'll use epoxy to fix it in position I made a plywood disk for the base I screwed the battery holder to that put some felt on the bottom and extended the wires I glued a couple of a small blocks inside the base to screw the disk to now I'm attacking the fan housing to get rid of any material I don't need leaving a bracket for fixing it's a bit of a mess but I did tidy it up afterwards to test it out I'm using blue tack to hold the upper rings on and make a good seal well actually work so not a disaster although I can hear the fans struggling to pull air in so I've decided to get rid of the base with the battery holder and put some feet on to raise the bass and let more air in through the underneath the battery wasn't essential and I'm not sure I would have used it anyway I did go back and countersink the holes and refit the screws later on the circuit board could do with a housing to keep the dust out plus there's a couple of LEDs in there that flash and it would hide those too the best way would probably be with a 3d printer I don't have one but I'll think of something and I'll probably make that later on that's definitely a big improvement now that more air can get to the fan that was a really fun project with lots of problem solving it worked which was a bonus and I think it looks great as well it could be improved with a stronger fan and maybe that's something I'll play with in the future but I am happy that it works hopefully you enjoyed the video if you did

"It worked, which was a bonus."

This guy engineers.

It’s scrap. It’s crap. It’s firewood. But some of the wood is good!

[u/neugo]

I love how 'bladeless' means that it still has blades, you just can't see them!

[u/justyeah]

Amazing workmanship.

I just wish he went with his first gut instinct to go with round holes in the base for the air intakes - as opposed to the horizontal slots! I reckon it would've matched the organic circular hole aesthetic of the main piece so nicely.

His channel is totally worth the visit.

One of my favourite maker channels

This guy's channel is great!

[u/Xanos_Malus]

My absolute favorite thing about Pask is that he always owns up to any mistakes he might make and is so open about the learning curve that never ends.

He makes me feel like if I just keep at it, I can do it, too.

Nice
