Hi Jerry! Yes, you are correct on all counts! There will be some growing pains to be sure... and I'll definitly consider all the of the parameters... One of the main reasons for the high cost, is the use of tool steel and heat treat through-out the total tool construction.. Knowing my machinist as I do, the whole tool, and every part, will be ground to within a tenth or two.. That is the only way he works! He has no less quality part in him.... when I spec parts to him, and I say it can be plus or minus .001" or .002", he says what do you want it to be in tenths of a thousandth, cuz that's what it's going to be! Any of the guys that have purchased our mag. mandrel can attest to that.. they were completely ground.... There might be a .0005" runout, because we didn't flood cool them as we ground them, and they were soft steel, but they are a much closer tolerance then if machined... Some money & time could be saved if the graduations were omitted, but if we set up to do one, we might as well do them all.... But, it is still in the research stage, and the fact that we have samples at hand, will give us a jump start on accuracy... I definitly appreciate your input Jerry, definitly some points to be considered.... till...later...GT
