How To Control The Eager Beaver


I’m sure that there is a better term for this but my Googling didn’t reveal one.  Analog is a secondary source for me, generally confined to albums that never made it to digital.  So I got one of these 45 year old favorites from eBay and it has a common issue that I’ve had with other turntables besides my current one in the past.

  When I depress the cueing for the tonearm it skips the first few measures .  I have to manually and slowly lower the tonearm and even then it still does this about half the time.  This only happens with certain LPs.  Is it record warping?

 

  I had my dealer check the cartridge alignment a few weeks ago.

 

  Again I’ve tried Googling this and I just haven’t been able to come up with much except improper cartridge alignment and record warping.

  Just wondering what people in this Forum, who are an amazing collection of knowledge, think

rather, inward skate, inward pull, happens naturally for any pivoted arm, on any smooth surface, no groove needed to make/see it happen.

anti-skate, which we apply, counters the natural force

you want your stylus ’floating’, so it drops down into the groove and reacts equally to input from either side of the groove as well as up and down. getting the most of advanced stylus, further down in the groove, depends on proper countering of the naturally occurring inward skate.

preventing an advanced stylus from damaging grooves, from uneven wear of itself, to get the 'potential' longer life, based on straight and proper even l/r surface contact

@elliottbnewcombjr Thank you for the tutorial on using the flat side of my protractor; dang thing didn’t come with instructions, now I know how to check one of the most mysterious adjustments to my turntables. The mystery being I never know if I’ve gotten it right, only when it’s obviously wrong. 
Next up: Overhang! I just put it where it looks straight and hope it’s good. But I probably need to start another thread on the topic. 

Yes, I inadvertently said excessive anti-skating would pull the arm inward.  The point I was trying to make is that, if the skip inward is not entirely a skating force, but, the momentum from falling off the edge bead, trying to use anti-skating to prevent this action will result in excessive anti-skating while playing the record.  It is better to set the arm for correct anti-skating and avoid the problem of skipping at the beginning by setting the arm down correctly.  Some automatic tables have an adjustment for this, those that do not, require one to have the arm cued up when starting the table, then nudging the arm to the right position before cuing down, or slowly manually cuing down to reduce the momentum of the arm falling off the bead.  

you can make a quickie overhang/null points protractor if you can punch/drill/cut a hole in a piece of stiff paper to fit onto a spindle, then simply draw a line across the center of the hole, and make some marks where you want them.

overhang is easy, centerline of spindle to centerline of stylus tip,

do not tighten, loosely snug, because you may be twisting the cartridge body sideways in the headshell a bit to get the best 'straight to the lines' for the 2 null points, then tighten speck by speck, re-check when tight, avoid movement when tightening

 

 

Elliot, you meant to say that skating (not “antiskate”) occurs even on blank vinyl, but the magnitude and even the vector direction of the skating force are different when the stylus is tracing a groove. Nevertheless some do set AS using a blank area on an LP. But try as one might there is no single setting of AS that will precisely counter the skating force across the playing surface of an LP. Experience for me and many others is just to set AS at some low value (some say ~10% of VTF, but how do you quantify AS force?) and hope for the best. I still maintain that skating force is not causing the OP’s stylus to skip, at least not skating alone.
