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...
