A 5 blade rotor. making our own replacement blades a fair bit o' resestance to rotation from the generator, therefore, balancing it on the generator shaft is probably a no=go. the owner, for whom i'm doing the work suggests balancing 2 blades against one another. But there are 5! not 2 or 4. maybe we make it a 4 blade... maybe we make sure each blade is excactly the same weight AND with CG at the same distance from center (sounds cumbersoe to get both mass And cg identical. suggestions?

My son-in-law had a broken metal cutting bandsaw blade. I did not want to bother trying to weld the broken blade, grind it smooth, and then try to temper it. I used a 12" hacksaw blade as a guide and drilled holes in the broken band. Cutting to length was easier than I expected. I used an ordinary tin snips. Drilling was easier than expected, too. I got three hacksaw blades from the band with a few inches of surplus.

Can i use fan blade as light weight helicopter blade or there is a difference in their design
Question by MuhammadK19 | last reply
I have a new powermatic 14" bandsaw with roller guides and a 3/8" blade. I would like to use a 3/16" or 1/8" blade but have heard something about "rolling out" the teeth on the blade if I use roller bearing blade guides. I assume this is due to the small size of the blade and it winding up between the rollers ( the teeth that is). Would block type guides be better or will the "carter" type roller bearing guides, properly adjusted, be OK ?

i had a cool idea for hidden blade we need 3 springs (the third one is to keep the rope strained and to activate the second trigger both springs have |dX |>0: dX1 > 0 ,dX2<0 (one spring for showing the blade, ione - for hiding , unstrained length the same) then man pulls the rope connected with the coil and this releases trigger A it cause spring 1 to reduce its length the blade appear then man releases the coil and activates the second trigger (B), which cause the blade's hiding it is only scheme, in real life it will take more springs and parts

Hey Everybody! I've been looking around and I've found many people who have made knives out of hacksaw blades, but I was wondering if it could be done with a Sawzall blade too. If I used a woodcutting Sawzall blade, then the knife could probably go through a limb of a tree faster, and then I could sharpen up the other non-cutting side, and add a handle of some sort, maybe out of paracord or Sugru. Add a Kydex sheath, and its pure DIY-ed. What do you all think? Would the Sawzall blade be sharp enough to cut a piece of wood with your arm (as opposed to the rpm of a Sawzall motor)? Would the Sawzall blade take an edge on the back? Would this be worth my time? Thank you!!!

Hi! I'm trying to make brass knuckles with a blade hidden inside it's for a cosplay. The idea is to have brass knuckles and at one point in the action of a button and out a knife inside the brass knuckles in a small compartment inside the fist. For reference I have the OTF Assassins Creed hidden blade. https://www.youtube.com/watch?v=xJx2VCH3V44 But on a small scale and with a button instead of rope. As you would do ?? Thank you very much!

I'm trying to figure out how to get the blade hub off of the bottom end of the crankshaft on my TroyBilt - Honda powered mower. There is no set screw that I can find, and it doesn't appear to be a thread off. There is a key, but I can find nothing that suggests how to get this thing off. I need to take it off so I can change the bottom crankshaft oil seal. This is a Honda GCV160 engine. Thanks for any input.

Okay. now I have a grasp on my amp (or should I say watt) draw. I now need to figure how to make this wind turbine produce what I need. I've bought a small 200 VDC motor to build my first turbine from. This is just my 1st hobby wind generator to see if I can & how well. Probably the wrong one, but it's cheap enough and sure I'll use it for something in the future. 400 rpm seems really fast to generate 12v! So that's my first question... is it? To achieve this speed , in my area (Class 2) I can expect 4 hrs a day wind of only 3-7 mph (trying to stay very modest), so I assume I need multiple blades and gearing. 2nd question; How do I determine how many blades, of what size I should make to obtain a certain rpm in a particular wind speed? Not sure I asked that correctly, so please bear with me. Once I have this generator in hand I will be able to measure the torque needed to turn it. Then I assume I need to determine a blade size and count to meet this need. If that is still not enough, I assume I will then need to gear it and re-calculate the blades. Anyone out there have the math to figure this?

Hello, I fell in love with the twin-blade ceiling fan pictured at the link below (for some reason the uploader doesn't work in either form for me) , but at over $800 I hate the price tag. I would like to try and DIY something like this for my new house, but I do not have the electrical knowledge to do it alone. I figure that if I can find two second-hand desk fans and wire them into a nice light fixture I could get the look I want without the price, but I need to know how to do so safely. I wouldn't want an electrical fire to burn down my new home! http://www.wayfair.com/Minka-Aire-Twin-Gyro-6-Blade-Turbofan-F502-BCW-MKA1488.html If anyone knows how to get these things all wired right it would be a great help!

Heylo everybody! :) I have a self-propelled mower that I am disassembling for a go-kart (probably). I've gotten everything off of it except for the engine. I know where the bolts are to take if off of the mower deck, but here's the problem: the blade won't come off. I've blocked the blade in both directions and tried to loosen the middle bolt by turning both left and right, but the mower is pretty old and the shaft and bolt are probably rusted to craps. I also attempted shearing off the bolt with a crowbar and hammer, as well as cutting the head of the bolt off with a Sawzall. The bolt dulled all the teeth on the metal blade for the Sawzall and dented the crowbar's edges. So does anybody have any suggestions? I'm really at a loss on this one. I don't have access to a grinder or plasma cutter, which would seriously help out a lot. I was thinking about picking up a cold chisel from the store, but if I'm just being an idiot and turning in the wrong direction or something obvious, I'd rather know that than lop off a bolt and lose some of the hackability of the engine. Thanks! - basementhacker

Nowadays almost all hand saws are induction tempered. It seems such a waste to throw them out all the time after they get dull. Traditional hand saws could be sharpened with a triangular file and a special tool to bend the teeth outward. I guess sharpening can be done by means of a dremel tool with a diamond disk, but what about the bending of the teeth? Any suggestions?

I have a propeller with four blades that acts as a wind direction weather vane. What I would like is for the propeller to make a whistling noise when it is rotated by the wind. Someone told me if I put a small hole or a slit in each of the blades it will make a whistling noisy which should change with wind speed. Can anyone tell me what size hole/slit I would need? Also at what angle would the slit have to be? Or can you tell me any other way to get a whistle from the blades when the wind is blowing? The blades are metal and about 200mm long (400mm overall diameter).

So i, like many others, have some strange obsession with Hidden Blades and really want one. However, i do not have the machines to make one from scratch like most of the walk thoughs on here, and since i do not have enough time at the moment, heres what i was wondering: Is there anyone out there with enough time, money, brains and skill to convert a shop bought hidden blade from spring loaded mechanism to the more realistic ring pull mechanism? I think it could potentially be quite a challenge, working around the already existing parts. I am talking about the blades on sites such as Forbidden Planet, and also i have found iconiccollectables.com selling them.

About two years ago, a number of groups at Burningman had LED displays on the blades, powered by the same Windmill. The displays on each of the the blades could be programmed with different sequences of tri-colors to form art or pictures. I am looking for someone to instruct me (an electronics idiot) or preferably build the parts necessary to put a similar unit up in the rural area I live in. The locals would be amazed (virtually no intelligence regarding technology!).

I started a set of simple bamboo wind turbine blades today. I'm using instructions for PVC pipe blades. This involves slicing up a plastic pipe (vinyl chloride is carcinogenic) but large bamboo is similar to a pipe and I've got some so why not try this natural material. If you have done this before, please share some insight :) To my knowledge nobody else has posted about this and all I've found online about bamboo blades is from large scale commercial turbines.
