setting VTF with a digital guage


Hello AGoners,
When I first purchased my VPI classic 1 I used the supplied shure stylus force guage. I decided to try a digital guage and then purchased a acoustech digital guage. My question is about the height of these guages. Both the shure guage and the acoustech digital are taller than even a 200gr LP. I have tried to make a small cardboard pedestal to place the guage on to make it level with a 180gr. record since that is what I play the most. Are you guys setting the stylus force guage on top of the platter or do you try to set the stylus force guage level with the playing surface?

Chayro, I'm pretty much with you (regardless of -- or maybe because of -- the different VTF readings I get when setting the gauge at different points across the disc or platter. And my digital VTF gauge reads to THREE decimal points, which makes it all the more absurd (IMHO of course).
Tketcham: I am not sure I understand your chart of height and weight. Could you clarify?
I will admit to investing in an Ortofon digital gauge, which is kind of pricy, but seems to put the stylus in about the right place.

You don't need a digital gauge... The Shure thing gets it approximately right...then use your ears... On the VPI arm use the large Allen wrench to move the internal counterweight (accessible from the hole in the back of the arm tube) back and forth until you hear what you like.
What range of variation are people getting? I have a cheapie digital scale I got off eBay and I don't get a variation greater than +/- 0.05g irrespective of where I put the scale: on top of platter or next to it (given my set up, this puts the scale at least .5 in. lower). I believe I can hear differences in this degree of variation. However, in my opinion, accuracy is not essential here. Precision is more important. One has to locate the correct vtf by ear anyways, so once one is around the area one wants it's just a matter of being able to locate the preferred setting again after repeated testing of different vtf's.

Even for someone like me who adjusts vta for every record, taking a scale out for every record seems insane.
