I port/polish heads for high performance engines. At present I use a pitot tube to map a port in the head. Sometimes the tube causes problem in checkin. Im wondering if there is a way of using a bare resistance wire and induce voltage and measure how quickly the wire cools or something similar...
I have exactly one of these from Shars and I tried it. Glad to see some one post on ideas. This worked but, the hone is traveling so quickly, I couldnt read it. It then became apparent that I would have to hook to some kind of PC or ?. Crap was a good idea though.

I am in the process of designing/building a automotive cylinder bore honing machine for myself. The one thing that I would like to incorporate is measuring of the bore on the fly. I really dont care about size, I am looking at bore shape. Yes I know I could use a incometer, maybe a topometer but...
Ok for an update. I am trying to methods of readings. I am monitoring the amp draw thru a current transducer and I have mounted a sensitive load cell under the motor. As thew belt pulls on the load cell, I generate a reading. Am playing with it to see which is most responsive and quickest.
Now...
Ok now you have got my good ear. The motor on the machine now is a 2hp. It does not have a name plate so I will hang a amp meter on it today. And you are correct, I do have not enough current difference to be able to hone by. That is why I like the idea of a transducer so I can narrow the scale...
Yes I am looking at torque transducers. I have started a spreadsheet with the different options along with cost. One is torque transducer, another is current transducer and another is load cells. If any one has other ideas , pass them along so I can take a look.

Yes this will work and I understand what you are saying but I need readings as the hone head Reciprocated so that I know where the tight spot is. You have to understand this is happening at 40 to 60 strokes per minute. I can read this shaft deflection, that you are describing, with a rotary...
I can do this except I can mount it on the AC motor and measure its force. Trying to figure what poundage transducer I will need. But you have a good idea
Mike: you are correct as I have a hone machine now and it measures percent load and it does it on a analog gage, but the new hone head I have built has a gear box and I tried to do the same thing but I dont pull on the motor hard enough to get a good reading. This is the way most machines work...
I am attempting to build a machine to hone the cylinders of a automobile engine. I need to be able to measure the force required to hone that cylinder. I want to be able to measure the force as it travels up and down in each cylinder so that I can determine the tight spot. I tried to measure in...
Even with the meter I have now, I can tell when the cylinder bore is small at one spot, but since the resolution is so small, it is only an indicator. What I was after is a wider range of reading, so that I don't have to stop so often and measure. Maybe I am asking for too much, but I just...

The meter is now 6 inches across. I can see the movement,but the resolution does not let me know when the cylinder is small in a particular spot. You can see it wiggle and you know it, but you cant use the meter to hone out of the tight spot. Can I rework the meter I have and just change...
I have a Automotive Honing machine equipped with a analog Percent current load meter. I only use from 65% to 75% in my honing, therefore I need to expand that resolution so that I have a meter that has a larger resolution just in the area I am operating in. I am needing some one that has...

Megasuirt may offer another alternative for me to pursue. I am already a Innovate dealer and have and am pursuing this alternative. And yes I am quite amazed at your knowledge of NGK plugs with blown Methanol. And you are correct in reading these plugs with methanol, but doesnt work as well...
Thanks Lionel
I am beginning to see what you have posted also. There is no cheap way. The one idea that I am pursuing is using a used ECM from a Nissan. It has location for 2 wide band and 2 narrow band O2's. I have one disassembled at present trying to fiqure out the wiring so that I can see if...

I build several cars for NHRA Stock and Super Stock and as close as competition is, I will kill for 5 hp. You are correct that reading the plugs will indeed tell which side of the curve you should be on. We run our engines extremely lean 13.5 afr and up to milk power, so if we are slightly...
Pat
I thank you for your suggestion and I apologize for misunderstanding your "sig". I went back and reread and now understand. At present I have 10 thermocouples and 2 O2 sensors. I have found that with a EGT, the readings can be a bell curve and I have to make of sure which side of that curve...
Pat: This is what I have now. One in each side of the collector. And I do move it around and that was when I found out that I needed more. Became very interesting as I moved the sensor
PS. I saw the posting for ENG tips. I am sorry if I broke any rules. Please inform me what I did wrong and I...
