Brian, put your hand on a horse that's just standing around doing nothing, and then put your hand on a horse that's been working.? ?You'll feel the heat. Part of what's confusing is the timeframe of

That assumes I have a large enough heat pump for the additional load.? I do not.

Brett, I found the fossil fuel reserves equally fascinating. I could never comprehend that much organic matter could exist in one place. That is until I learned on a Nova show that bacteria that we

The law of conservation of energy says energy can’t be destroyed, or created, only have its form changed. The actual kw usage, the “draw” you actually pay for - that energy comes into the shop

I’m not sure I agree, show me the heat involved in this: I agree that there is heat created by electrical input, but I don’t think all the electricity consumed is dedicated to heat. For example,

Was there a reference earlier to using a loading dock light arm to suspend the vac hose and power cord?? Perhaps none were long enough and or could not support the load of the hose?? There is one at

Electric motors (like pumps) only draw the energy from the power source according to the amount of WORK being done. A motor idling will only draw the energy from the source through mechanical losses

You are splitting hairs. My point is simply whatever the consumed electrical power is for a given day as measured by your electric meter, ALL of that power turns into heat in your room. Obviously if

TJ, you are presuming that a motor always runs at a constant load. That is not true. And the power consumption of a motor, and the current, depends on the load on the motor.

Brian, yes, all electrical input is converted to heat. The force to cut something turns into heat eventually as well. The power is not all consumed by the motor, but all of that work ultimately ends

No, not all energy to do the work is converted to heat. For example, your saw idles at say 1hp, a heavy cut is consuming 3hp, that’s a 2hp or 1500W increase. Picture a 1500W heater, which

The holes for the bearings are through holes, correct? Brian Lamb blamb11@... www.lambtoolworks.com

Mark, Thanks for the explanation. You are right, I just chose simple words. Law of conservation of energy is something learned early but this last bit I never realized or if I was taught/told did not

Imran, I think perhaps it's more intuitive when you realize that it's not actually "thermal loss".? It's not quite right to say that it's "loss", and likewise not right to say that this is "not true

Brian, That is where I started. At least 80% of the energy is consumed in doing work otherwise it is a pretty inefficient setup. But these guys have convinced me that the energy used to do the work is

Joel, Is there going to be that much space between the two pieces or is thus where the gears go? Randy’s version has gears on one side only, if your version is similar than is there enough depth in

You all are missing the point that a lot of the hp/watts is actually consumed doing the “work”, whether it’s sawing the wood, jointing, planing, sanding, lighting or even compressing air. It

The holes I reamed, I reamed to a slight hair below 26mm..the ID hole on the bearing is 10mm..I used a 10mm bolt to secure everything together

Randy, I guess the nut at bottom is smaller than the ID of the bearing. I have only seen smaller reamers and the nut or the threaded rod is close to the size of the reamer OD. Just was curious how you
