John, I have a C3 31. If you have not used the thicknesser for four or five days, it will not be happy until you clean and lubricate the table. If the material is even slightly damp, forget it until

Well, I can quantify this… a couple of houses ago, I had a 25x35 shop with 8’ ceilings, built out of Integra block (very hollow block with poly foam sprayed in the cavities), then insulated with 1

This is my last post – too much time typing and not in the shop today. Your 2-ton AC unit can remove about 24,000 BTU of heat, which translates to about 7KW worth of continuous energy removal

It’s counter-intuitive, but it is the way that it works. If you feel like you’re cheating the universe with your free heat, you may feel better knowing that you’re paying for much more energy

The theory of this topic is interesting. Let’s take a practical look at the situation. I have a 600 sq ft, insulated, air conditioned shop with a vaulted ceiling in Phoenix I believe the 21 year old

Please excuse my terminology if I get it wrong, Well, my simple way of thinking is, that given the energy required to turn the motor, to operate the machine ...to achieve the cutting, planing sanding

Yes – exactly. It’s rare that there’s a free lunch in life, but if you want the heat your tool makes at the same time that you want the function of whatever your tool does, then this is one of

TJ, So you are saying that in fact an electric motor is MORE efficient than an electric heater, because you get the same heat output AS WELL as the benefit of the motor having performed work...well

Marty, you’re confusing instantaneous energy vs energy over time. If you turned your 1500w electric heater on for the same amount of time as a cut on the table saw – 5 seconds or so - you would be

If all you are considering is the heat output of the machine and not the financial costs of wear and tear on motors, belts, bearings, etc., then yes, an electric power tool is just as efficient at

I agree with Brian. To take more of a devils advocate position on this topic. If all the energy was being converted to heat then we could substitute our saws for heaters. Any of you who live in cold

I was going to suggest to rerun the board after planning without changing table height. It should eliminate resistance from cutter or concern of cutting height. Imran

I agree with Brian, start with cleaning and waxing the table. That should improve your problem, but may not completely correct it. Then make sure your knives/cutters are sharp. They can also

Maybe, but foolish is relative.? My point is that it might be worth quantifying, since everything is a tradeoff. For exampling, using my previous estimate of costing $2.50/hr to make up for lost DC

TJ and others, My simple mind may have missed the point of these theories, but are you telling me that it is as efficient(financially) to heat my workshop with a running machine as it is with an

Brian, an LED light bulb might be more “efficient” in the sense that you may get the same number of lumens as a 100W tungsten bulb with only a 15w LED bulb, but that’s a different problem. The

Lumens is "work" only as metaphor, and by the same token, heating is also "work".? ?The "work" a heat lamp does is heating for example. Ask yourself this: where did the light "work" go after the

As I noted, may not make sense for you.? Obviously I'm not assessing your specific application, just noting that assessment is more complex than cfm x outside air temp.? For example, there is no

Agreed, the horse has heat, but in the case of lighting, the lumens is the “work”, we get the same amount of lumens from 15 watts (LED) as we do 100W of incandescent. Put the 100W vs. the 15W in

I am an electrical engineer who is 12 credits short of a second degree in mechanical engineering.? TJ is correct in that any energy coming into the room either turns into potential energy or it is
