If you need to move large items(Go Kart, Picnic table, or a vehicle)in and out of your back yard here is a cheap and very easy way, with 17$(if you don't have to buy any tools). If you want to make a box that looks like a professional craftsman hand made it, but don't want to spend hours measuring and hand fitting, just follow these instructions and you'll not only impress your friends, you'll even impress yourself!All of us have made boxes of one type or another. If you're anything like me, you love woodworking carpentry, but hate the tedium of finishing.
This is the first in a small series on making wooden toys from leftover pieces of wood or MDF. Easy Fill - Another Pair of Hands in the KitchenIf you ever have to fill plastic bags for freezing or storage you're more than familiar with the problem: you're holding a pot full of stuff in one hand and trying to hold open a very flexible bag to pour the stuff in with the other hand. See video for a complete over view and details to many steps that are difficult to put into words. My son came to me with a photo that he found online of a desk calendar made out of wooden blocks.
If you are a woodworker or not, chances are that you have some scrap wood taking up space in your shop or garage.
You can make an awesome looking cutting board and it only takes a few hardwood offcuts to do it. How to successfully remove a nail from a delicate piece of wood without damaging the wood itself. It's hard to think of a simpler yet more effective woodworking tool than the cabinet scraper – a flat, thin, post card-sized sheet of spring steel dragged by hand across a wood surface to leave a glass-smooth finish.
When I sat down to design this bench, I forced myself to make it as simple as I possibly could while keeping it attractive and comfortable.
As with any new project I've attempted, each step along the way is unfamiliar to me and some steps are deserving of my apprehension, while others equally as worrisome turned out to be a piece of cake. Here are three (or four) field-expedient methods for drawing curves that I use frequently when building houses and furniture. This awesome looking live edge coffee table is made using a slab of wood and some flat bar steel which I bent into shape, so no welding involved.
Plywood gets alot of stick in the guitar world, being reserved for mostly only the cheapest guitars.
A Portable Workshop for those of you that don't have much space or a compact cabinet you can carry all your stuff to work in other locations.I wanted it to keep it as small as possible for those of you that don't have much space or your car and tools share the same place. Here are the complete steps toward building a 3-stringed musical instrument, taught and inspired by the Andy Mackie Music Foundation. Hence, I decided to mount [through holes in the centre of the] 3 poles on a steel barrel [which would help with accuracy]. What I wish to know from you guys is where the mechanics of the system are optimised and can be done so further and what flaws this design might have; what changes are to be made to the positions and locations of the various components and what changes are to be made to the design itself is also something I wish to know. Do you have a closeup of how you are attaching the main bow, support pole, and anchor to the barrel?
3) Bamboo is very inferior to some woods for energy stored when flexed, but an artificial wood composite of bamboo fibers in some binding matrix may be as good as the best woods but at > ten times the cost.
I like the tried and true crossbow myself for its elegant design and ease of use plus can be precise shooting at over 100 yards. Perhaps very slight (not easily detected without precise instruments) sinasoidal variation in the bolt OD for bar codes is cheaper and better. At some point you will want to estimate the tension needed in your cords to develop the desired power.
Safety: whatever you end up with, make sure it has a foolproof way to lock out against misfires.
As for materials, my first impression, before I got to Billy T's post #6, was also the same concern about bamboo and rubber.
The general rule for struts and beams is that they tend to be stronger in compression or tension than in shear.
Another thing about shear is that it decreases in distance from the fulcrum, so you can economize by letting the beam gradually taper off. The simplest geometry would be an isosceles (or equilateral) triangle, with the base oriented parallel to the string of a conventional bow, and the apex oriented where the grip would be. If weight is no concern, then you may be able to take a leaf spring as suggested and adapt it. The last issue, which I will leave open for now, has to do with figuring out the amount of power needed to launch, and how to develop it using a spring or elastic cord.


Be sure you use safety goggles whenever you're working with springs and things that want to fly apart. One last thing: you might want to consider investing in a gauge, or making a test jig of your own, that can measure tension. I dont understand the design but the best DIY material to use for a small crossbow would be an old leaf spring from a car, cut to size with a hacksaw. The problem with leaf spring are that they are high tension, for a bow only 1 foot high, they would have a pull weight of some 20 or so pounds, unfeasible for such a small design.
All three will have a hole drilled in the middle in the barrel will be threaded through then fixed with superglue.
But it is never going to be fully pulled for a long time since there is no holding or release mechanism [like a crossbow].
As Billy pointed out, the rubber by itself propably wouldnt be strong enough to provide all the force desired. I dont get what exactly do you mean by keeping it out of shear [in context of the pictured schematic]. Wouldnt such a configration drastically reduce the amount of deformation the main bow can achieve? Bamboo is good enough since the idea is the make a small bow lasting for about 5-8 months and costing just a few dozen dollars, easy to make and quickly replaceable. I have been seeing these lamps all over the place as of late, and I simply love them, so I decided to make one for myself. In this instructable I will show how you can build a simple toy airplane, with spinning propellor!
The last picture shows 95% of the handle tools used to make this toolbox, will they all fit into the toolbox?
Taping is a precaution that can protect your rifle from splintering or cracking from falls on hard surfaces. If you do use plywood for your beer caddy you may find that cross cutting the plywood on the table saw or bandsaw leads to tear out. Giaco is a very talented maker and filmmaker whose projects I've been following for quite a while now. It features a very simple design where the wood is really in focus and has a remote control that attaches to the back of the lamp.
He asked for a couple boxes to sit on the guest sign in table, one to hold a bottle of wine and the other would hold notes from friends and family attending the wedding.

The idea behind the bow is the create a small but powerful, easy to make bow that can shoot at 130-140 fps. Also tell me if you like my design, if its original or not and what similiar or other designs you recommend. Rubber can store a lot of energy per pound, if released slowing - for example when powering a simple model airplane. There are many more ways to be bent than straight so upon release it becomes bent again, but that takes energy, which causes the cooling. Another pioneering first, Barnett has the only patent protected, ultralight, super strong Carbon riser available for Crossbows.
Hope the bolts have some ID hard to remove* so cops will know who silently killed with it from blocks away.
Bamboo seems to me to be risky although it has the advantage of being relatively strong (for grass that is!) due to its tubular geometry. Which is why this design is based on dividing the force so that low tension materials at a pull of just 5-6 pounds could provide a high powered release. I imagine they have to be just a little less tense than the maximum flex [at full pull] between the points where its attached? The strut [support pole] would have some give so that it can contribute to the rebound too. This would obviously reduce the power output, but that is exactly why I added the support pole and rebound strings, so that together it can be more snappy without being high in tension and pull weight. There are many commercially available sanding blocks, but these sanding blocks can be made quickly from scrap 2x4s and spare dowels. The problem with small homemade bows is that most materials that are flexible enough are also weak and unable to stand the tension of a single-string bow design.


The support pole and the anchor are semi-elastic thin wooden poles and they help to store energy and provide more speed to the release without the required tension by dividing the force applied and energy stored.
As you plan a steel tube and lots of other structure, you don?t seem to be concerned with the energy per pound aspect. In other words, greatest efficiency would be from a cord that's arranged like a common slingshot. One you have a sound solid frame that's lightweight cheap and easy to build you can solve the problem of creating tension using the frame for support. Keep in mind you can get the same effect by using multiple wraps of the elastic cord, attaching at the longest point from the fulcrum. Besides, this is a low value project with one primary goal in mind - a low tension, divided force system with fairly good power.
Such division of force would be inefficient at bigger scales, but this bow will be only 1 foot high, so this is the only way to keep it low tension and powerful, no? Shooting scary fast arrow speeds, the Ghost also comes complete with Barnett's AVI technology molded over laminated limbs which reduces noise and vibration up to 30%.
If you look at how guitar strings are tuned, it's a worm gear which locks without slip.
You will also have to figure out how much the cord will have to stretch versus the power power required and the length (of the arrow shaft) over which the power is developed. Besides misfires, you don't want to get whipped in the eye, or have a piece go airborne. So for best use of your material, which is fairly light for its strength, you want to try to keep it out of shear (sideways strain). That sounds pretty dangerous to me, but with adequate precautions it could develop a lot of power. The barrel would have to be threaded through a central hole which has to be drilled, but do the smaller string holes, placed together, have some effects on splintering or something?
Think of it as being oriented towards understanding and designing, developing and making a toy or a non lethal weapon.
These designs also ignore how much of the force comes not from the string but from the body of the bow, something pretty obvious in modern compund bows. The support pole stores additional energy with the rebound string which would transfer it back to the main bow causing a faster rebound.
The Aluminum flight track, CROSSWIRE Strings, and Whiplash Cams also provides a smoother, faster, quieter, and more precise shot in a compact fit. Pianos use a pin block which eliminates the gear, but it may be hard to implement for a string that is subjected to shock. Once this is known, it's possible to estimate the amount of force placed on the structure, and from there you will want to know the specs on your materials, particularly the maximum safe limits in compression and shear. Consider using a safety, a slack line that will take up the load if the cord snaps, becoming taut and holding the pieces together. You've seen this before, and also in overhead struts and beams in buildings and so forth.
Other lighter spring materials are available, but I have no idea about the cost and specs for them.
Its going to be use primarily for target practice and the focus of the project is the development rather than the use of the product. The straightner limits the pull length and ensures that maximum displacement of the main bow and support string is achieved while also working as a secondary support string.
With the ADF (Anti-Dry Fire) MIM (Metal Injection Molding) trigger system and 400 FPS speed the Ghost CRT is the crossbow to own! Obviously you can develop as much power as a leaf spring using bungees, I'm just not sure how many it will take!
At some point you may be able to devise a variable click adjustment for dialing in the pounds of tension. It keeps the support pole taut and allows it to bend just enough to maximize the rebound of the main bow but not so much so that the support string loses its optimum output of power.
The relative tensions of the strings will have to be calibrated at manufacture, and some advice on doing that is highly appreciated.
