I am having trouble performing the length check out on my Romer. I have not checked length using the bar in over a year. I recently replaced my 6mm ruby ball (they don't bounce well) and calibrated it with help from this forum. Since I had the bar out already, I installed the 15mm probe and started checking length. The conical seat distance (711.168+/-.040) came in for most of the points but never for all 5 checks. I have tried multiple times with no success. My setup consists of the bar sitting on my granite table, being held down with clay(I was told was sufficient). The arm is situated in the middle of the bar and I attempted many different articulations and also keeping the same position. I just can't seem to obtain an accurate read. The bar hasn't been called since 07' but has only been used one other time and has been sitting on a shelf for the last year. Here are some of the results:
Mike,
You are not looking for consisntant readings. You are trying to fall with in 711.208 and 711.128, your last three checks fall within thoes secs. I agree that clay is not the best bust it can be used. I used clay to do my length check and I got out of spec readings, I then use a lot of clay at diffrent locations and my resutls came out better.
