    I port/polish heads for high perfor

    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...

    Automotive Hone Machine

    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...

    Measuring rotating Force

    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...

    Percent Load Meter

    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...

    Cylinder Hone head needed

    I have an older vertical automotive cylinder hone. I really prefer the vertical to some out today. The hone head is an older Sunnen AN model as is quite worn out. I know that in the past few years new technology has come forward to better round out cylinder bore. I would love to build or maybe...

Am getting noise and can't filter out. Have heard of Fourier but do not know how to use the calculations or if there is...

    Cooling Tower for water dyno

    Have a water brake dyno. Want to consider reusing the water as it comes out of brake. Temp is approximately 150 degrees. Need to cool down to under 100 degrees. Any suggestions on how (I) can build some sort of cooling tower to transfer heat out and reuse the water. thanks

    diy crankshaft balancer

    Want to build a crankshaft balancer. Been reading up on dual plane dynamic balancing. Looks like I will need to use piezo accelerometers or ?. What kind of software will be needed. What kind of dac card? I know(too many questions not enough answers). Any help and all help would be appreciated.
