that is an idea I'd not considered as well. thanks.

thanks all for the time, information and thoughtful discussion. The vibration and movements in addition to seeming more once elevated, with time seemed to get worse. This precipitated me replacing the 3 drum shock absorbers and setting the washer on feet made of sorbothane. At present going...

the washer is a front loading type with axle of the drum going from the center of the front door to the back of the washer. the axle is close to horizontal. the pedestal is made for the washers and has a drawer in the bottom. the washer is firmly attached to the pedestal, essentially bolted...

Thanks Balancore for that input. I had considered mounting them on opposite sides as you describe, but put them on one side hoping to create oil current up over the top cut out and down the other side to bottom cut out and up again. the thought that the 4 resistors be a steady force for flow...

thanks Baluncore I will round up the parts to make the arrangement more clean and shortest possible runs while trying to leave enough space for cooling. I have some copper sheet 1/16 inch thick that I can use to make the connections. It appears I may have access to some high temp CE rated...

Thank you Davenn.

Thank you Davenn

the help here is much appreciated. the analyzer I spoke of did read the circuit and confirmed that there was about 305nh inductance seen at the input. I used a variable cap in parallel with the resistive network and found I could null out the inductance at about 100pf I the mid 28mhz range. it...

Dave, I thanked you for your input and your advice on the parallel cap confirmed my thoughts. to say I did not want to follow your advice is assuming facts not entered into evidence. My desires are not the only thing that figures in the project. silly as that may sound. Thanks again.

Tech99 thanks again. you're concern for the peak voltage is noted. You might be right on the PVC schedule 80 pipe. to say the hot resistors are mounted right on the plastic is not exactly true in that the mounting clips for the resistors are mounted on aluminum bars. my hope is that...

thanks. I'll work on it.

Thanks for your help tech99. by saying that if I resonate with a shunt capacitor, then the resistance will go up. Do you mean to say the impedance will go up? my thought was that the resistance will remain constant and the reactive components in the circuit will change. If my problem is...

Thanks for the help. The analyzer I have may be able to read the inductance of the resistors. I won't know till tomorrow when I return to the shop.

Thanks for the help guys. I'm quite sure the resistors are not wire wound. I know that ceramic does not conduct, I think from looking at the construction that it is probably a doped mixture that has been fired. some quantity of carbon mixed with the slip to make 50 ohms. there is no evidence...

Hi Dave thanks for getting back to me so quick. The resistors are not wire wound, but are ceramic. They are made for oil cooled dummy loads. My thought was that maybe making my connections with copper strapping as short as possible, rather than 12 ga stranded wire would reduce my...

I searched for dummy loads and found nothing on point. If there is and I missed it I apologize. If this is not correct section let me know and I will re-post. We need a high power dummy load in the 4kw range. for the amateur hf bands. The oil cooled "cantenna" type are at the most 1.5 kw...

The torpedo and rocket motor were held together by a center section. basically an aerodynamic tube split in half lengthwise. It fit over the aft of the torpedo hiding its control surfaces and chute pack. And around the front of the rocket motor. two bands, one in front and one in the back...

Thanks very much Berkeman. That makes sense to me. As I understand it he was alluding to some energy being transferred from the loss of mass. I didn't think it made sense, but he was a rocket scientist after all.

The USN used to shoot ASROC from box launchers. It was a torpedo with a rocket motor on the back. it was ballistic. The rocket fired and then separated mid flight. the torpedo continued on, a chute was deployed to slow and I think stabilize the water entry after which the torpedo went on...

Andy I appreciate your help. I hate to admit that the advanced undergrad math is probably beyond me. I am just an old curious guy. I am not in a physics program, just curious about what causes this to happen. In my mind I likened it to rf passing over a knife edge being diffracted into the...

this makes some sense to me. Can you explain just what the light is doing to present this result? I can see it bending around the aperture blade and creating one spike but why the opposite? is it a function of the optics beyond the aperture blades? In lenses that have nine blades, the...

Hi been a while, but you guys always square me away. I've recently noticed that when a night time photo is taken with the aperture closed down, (higher f number) seen in the resultant image is a starburst radiating from points of light. The general wisdom is that it is cased by diffraction...

CWaters thanks for the recommendation. found one and have it ordered. Mike

Thanks for the quick responses. It appears I might be biting off more than I can chew. regards, Mike

Hi Once again the intricacies of flight seem to be escaping me. I have taken up model flying as I think I mentioned in my "Lift- more complex than Bernoulli?" thread. So far I have been flying models with wingspans in the 60 to 70 inch range. When choosing airplanes, I noticed that in planes...

Alphazero thanks very much for the links. I found the allstar link especially thought provoking. I knew I was missing something. Mike

Hello Over the past year I've taken up the hobby of RC model airplane flying. During that time I've had many discussions with fellow modelers about lift. I've additionally read a bit about it as well. Most explanations I see like to explain it on Bernoulli's principle. That the wing...

Bob S Thanks for that. I won't be using it to convince my friend but will dig out my old texts and see if I can do a little study to make that work. Does that formula make provisions for pole numbers? As Phinds has mentioned, I've tendered a last effort which if it fails will just be...

Thanks Antitiphon He was not confused on the construction of the alternator in question. Just has long held ideas that he is reluctant to revisit. regards, Mike

Phinds Sounds like good advice. thanks Mike

Thanks JN Might be a little too high level for me as well. Mike

Phinds and KN Thanks very kindly. the finite but very large resistance argument may allow me to actually use ohms law to show him what I'm getting at. if I use a hypothetical of 10billion ohms and .000000001 amps, I can show that there is 10 volts across the output of the alternator. I...

In a recent discussion the output of a single-phase permanent magnet alternator was the topic. The alternator has a 6-pole rotor and 8 coils in series wound on 4 cores. Output is taken from the opposite ends of the series wound stator. Another fellow made the statement that with the...
