In the name of aur earth clima top meeting here in denmark and the invyrement on the globe
how do you changeling to cut down the cost on power used in the shop
electric bill oil bill water bill if you havn´t think of it yet then there is always the solution to build like a gentleman (not that I say it is the right way) like a galoot only with manpowert tools like the old day´s no was thinking abaut sunpower for electric, sunheat the water both for bath and for hause heating , and hot air furnace build aut of sodapopcan´s, aircooling the unpowert way , by winmilll, solarheatet lumber kiln, magnets motors and so on let me hear and see that LJ´s is into it I now that we have startet everybody of us (recycling , reclame lumber make small project aut of scrap pieces or from the box were small peices you think that they are too good for the woodburner)
there is great info and vidio´s on youtube if you don´t now anything abaut it for my self is going for the hot air furnace build with sodapopcan´s (there is even one I think in canada who living of it)


sorry abaut the spell hope you get it or else ask

I am not sure I understand the question, or questions. But I am assuming you are asking…

“What are you doing to reduce your power consumption in your shop?”

I am NOT going to address my answer in terms on environmental impact, or the science, or lack thereof. There is simply too much conflict in that area. So let’s address the issue from the perspective of economics and comfort. Again, because everybody like to have more money in their pocket, and wants to be comfortable.

Things I have done to reduce my power consumption and increase my comfort in the shop include…

#1. Insulated the roll up overhead doors with “Reflectix” insulation. This is an alumized Mylar covering over fancy bubble wrap. It goes a LONG way to reducing heat gain in the summer months. This is in turn backed by rigid foam insulation, and then another layer of Reflectix. Since my heating, and more importantly cooling is done via electricity, this helps to keep the bill under control. #2. An in progress project is adding R-30 insulation to the attic space over the garage. This area was completely uninsulated when the house was built. The reason this is a PROJECT and not DONE is that there is decking on top of the trusses. #3. For more and more tasks, I am resorting to hand planes, sanding blocks, and my Marples pull saw. Not so much for cost savings, but because it is quicker, easier, and faster to zip through it with the hand tool than it is to set up a power tool to do the job…

For my environment, the biggest hit energy wise, cooling. If I can prevent heat gain in the first place during the hot months, and reduce heat gain into the living space at the same time, I more than negate any energy impact my power tools cause.

As far as water issues. I use almost exclusively natural finishes like Lemon Oil & Bees wax, or Boiled Linseed Oil & Bees Wax. (BLO is more durable, lemon oil has a more pleasant color and smell, ESPECIALLY on Walnut).

As far as handling solid waste, much, but not all of what I produce is burned in my BBQ pit (All the safe material to burn). Shavings and sawdust that are safe for composting are composted in a friends compost pile

and the goal for me this winther is to get enoff sodapopcan´s to build the hot air furnace

my intencion on the blog was never to go the politic way I will never do that it´s was only to here abaut if anybody had some fun with it and maybee new idéers

our shop is in our basement and there’s not much heat going into the space … so most of the woodworking is done spring to fall rather than heating it.

Here is my plan Dennis. I will not build shit that needs replaced in ten years. I will not use a finish that will not last ten years. I will do every thing I can to buy from small companies. I will use used tools and fix them when I can. More than anything I will enjoy and treasure my craft for the short time it exist as a profession.

I guess my main contribution to the environment is a tendency to use hand tools whenever it is practical. My shop is very well insulated including floor, ceiling and walls with triple glazed windows. I have to admit though that I did this mainly for my own comfort. I’m sure that producing all the insulation, glass, wood, etc. had a negative effect and I’m not sure if using all those materials make up for it. I do keep the shop heated in winter, but not too heated, just enough to keep my tools from rusting and finishes usable. When I’m using machines, my shop vacuum exhausts heat. The same goes for the machines and lighting fixtures, and altogether it makes it warm enough to work comfortably. I have always hated the idea of wasting resources and poisoning nature. To me this is just common sense.

I would like to say that it is a good thing that so many are concerned about the planet we live on, but we shouldn’t let ourselves be misled by fanatics on either side of the table. We still have to live, work and raise our families. Let’s just hope that we can do it in a smarter way than we have been doing it.

I’ve found that a set of Tyvek coveralls like used by Hazmat people go a long way in keeping my clothes clean (My wife appreciates that) and it also allows me to work in a cooler shop comfortably. I set the thermostat on about 50-52 and work there. The shop in the morning is about 42-47 degrees. so If I’m only going to be there a short time I don’t even turn the heat on.

Could We turn off the computer? By that I mean when we are not using them. Just leaving the monitoer on sleep, costs an extra $50 a year. Most people leave the monitor on sleep, instead of pushing a button to turn it off. That amber light requires electricity. Also a lot of tools still consume electricty when off ( if left plugged in), so maybe a master switch to the whole shop will help a little

Unfortunately, I do not own the shop where I work, but we do use scrap wood for heat in the winter and compress sawdust and burn that in a smouldering fire too! There are lots of big windows in the shop so we do not need that much extra light.

I am adding as much solar and wind assistance as I can. Since I did not have the large upfront cost, I am buying a solar panel at a time and putting it in place to help power the shop. I have two small wind turbines that charge my cordless tool batteries…. I have also added more windows for ambient light and will be putting in some skylights in that regard. I have my shop wired, and most of my power tools set up to run on, 220 so they use less. I am going to put in the passive cooling system that Dennis sent to me (tubes underground). I already have a semi passive heating system (wood burning stove) all in all I think I have reduced as much as I can with the current technology….but as new things come up…I will certainly consider the benefits to me and the planet.

I haven’t had time to do anything but stake out a patch on the cooler side of the shop. Mostly I will be limited by the amount of space available. I haven’t done any calculations yet…but hopefully the patch available will be just a bit bigger then required….The small loader/backhoe that I will be using is currently not available so I will give more info as soon as I can get it and get some work going.
