    Make a Bird Whistle

    Thanks for that inspiration Amaries. I'm just wondering if the inside cavity was modified to be smaller if it could be a dog whistle? I could envision an image of my dog instead of a bird on it. Maybe not. I sure like your design.

  • Super Solder Inlay for your Woodworking Projects

    A friend working with the armed forces told me that the military and the medical fields still use lead solder. That was a couple of years ago. The reasoning was that in both cases they wanted the highest level of long term between failures. The solder which is lead free has been know to grow whiskers and cause shorting whereas lead/tin solder isn't prone to do that. So if it can kill you or save you it's O/K apparently but nothing in between. PS, this is a nifty project. Too bad the lead free solder works at a higher temperature. I will have to look around for the alloy someone mentioned. By the way the chap who was asking what kind of solder whether radio rosin core solder or acid flux core solder - neither one. Just straight solder with no flux as in plumbers solder. Flux would contam...see more »A friend working with the armed forces told me that the military and the medical fields still use lead solder.

    De-Rust Your Old Table Saw

    WD40 can be useful but it's not good to coat fine parts as in a sewing machine or expensive guns. Once the carrier evaporates from it there is a sticky protective film. If that's what you want fine. After you get the surface of your band saw, table saw, etc, clean simply put a small tarp over it. You will find that it does a very good job of keeping new rust off. Still a good idea to put some sort of protectant on the surface to help leep rust off but also to make the surface slick. I found a saw shop that carried a spray for applying to saw blades. I use it on the blade and also the surface of my saw table. Wow! It really makes an improvement to wood handling.

  • How to Make a Cool Dragonfly Sculpture From Scrap Steel

    Very nice, looks like it's ready to fly off. Thanks for sharing then design. Thanks also to the people who contribute their suggestions like the one about separate buffing wheels for steel and stainless. I would not have known about possible rust on the stainless because of regular bits of steel embedding in it. Must remember that for my own future projects.

    DIY All in One Solar Power Pack

    I am a HAM radio person and so require clean power to run my transceiver. I have found PWM charge controllers give me quite a nasty bazzy hash during the charge period during the day. Has anyone had experience with this? Is it just my old Morningside controller or are all PWM controllers like that and how about the other one mentioned the MPPT controllers? Do they introduce a lot of hash in the power stream? Life is a mystery and this is just another part of it all. :-)

    Steel Wool Emergency Fire Starter

    Something not mentioned is good fire starter. A 35mm film container filled with dryer lint and another container filled with dry pitch from coniferous trees. The pitch burns hot like a torch and can be used to get damp wood burning. I used to take one or two disposable lighters with me until I was on a scout trip up in the mountains. It was cold and wet and the lighter that was in my pants pocket would not ignite. The fuel in it would not vaporize. That was a shocker. I was saved by a young scout who brought penny matches in a zip lock. No one was using batteries and steel wool back then. Where we went moisture probably would have made it tricky to use. We being on the wet coast of Canada. :-)

  • SunCalc: How much sunlight is my plant getting? A Sun light Calculator for plants

    Yup they can. No more fading of upholstery close to a window if the windows are of recent design. Poor plants don't do well by them either, they don't get all the spectrum they need to thrive.

  • SunCalc: How much sunlight is my plant getting? A Sun light Calculator for plants

    This is a nifty idea. I recently had several double pane windows replaced because their seals had failed. The replacement modules are built to modeern codes and so block UV and some other parts of the light spectrum.

    Easy Thick Fluffy Pancakes

    Terrific idea about separating the eggs and fluffing up the egg whites. I've never done it before in recipes other than angel food cakes. Must give that a try on other recipes like this one. I don't much care for the suggestions by kivajiva. For one thing sugar and egg works well to build cell walls in baking. Without the sugar the baking tends to not rise as well or stay risen. Regarding the PAM spray, it works well for me when cooking pancakes on a griddle. I like the quality of the end product. I also use coconut oil to lube the griddle but PAM works better and is much easier to reapply. To each his/her own I guess. In regards to things like PAM being filled with chemicals, too late, we are all made of chemicals including the water we drink and the air we breath. Oh noooo.

    I saw something like this done as a 3D printing but then you need a thousand bucks worth of printer to do it. This is nice and easy with good instructions. Thanks for sharing it.

    Building a Shed

    Nice shed and I like the idea of no wobble. There is a problem where most of us live though and that's to do with how long a structure will last if embedded in the soil. Fence posts tend to rot after a very few years. I have taken to making a hole, inserting a cardboard tube into the hole and filling in aroundn the tube, then pouring it full of concrete. Last of all and before the concrete sets I put in a steel post holder. Later the post gets inserted into the holder and bolted together. The fence posts last a lot longer and if they ever do rot its easy to unbolt them and put in another. I would think that may be a better way to go with this little shed. Just a thought. I hate building stuff only to have the weather and bugs rot it away.

    Cracking Single Dial Combination Locks

    All of this is quite interesting. We had a young friend, a teenage girl, who really had the Master combo locks mastered. It was scarey how easy it was for her. I still don't understand fully how she did it but she could open any Master combo lock in under three minutes and usually a lot less. It was by feel and by listening. No fancey charts or anything j, just touch and listening.

    8 Life Hacks With Steel Wool

    The school janitors in my district use a tennis ball on the end of a broom handle to scour off running shoe scuff marks in the halls and the gym. I tried it and it works. You make a short cut on the ball just the right size to allow a broom handle to be inserted.

    Aerial Photography Super Affordable Kite

    A 4 lb weight fishing line would not add much to the load and may do the trick without a lot of added expense. Must try it. I just got a digital canon camera for 42 at a garage sale. Not too big or heavy so if it still works (waiting for a battery from China) it will be going up in the sky.
