It has been so long. I do believe that if you loosen the grub screw at the back of the arm rest/lifter platform you can twist the entire platform around the post, (take the arm out of the arm rest first and best remove the head shell) the post is threaded. One turn should do it then reposition the arm rest, tighten the grub screw, put the head shell back on and you should be good to go.
help with clearance between sme 3009 arm's tube and arms lifter assembly
Hello guys,
I’m writing to ask for your support to correctly couple a Thorens TD160B mk 2 with a a SME 3009 improved seried 2 removable headshell arm. The cartridge I use is a Benz ACE L.
I bought the arm’s base and mounted the arm, verified its null points with the protractor, regulated the pickup orientation and put the cartridge shell parallel to the LP surface with an LP on the mat.
So far so good.
The point with me is that the clearance between the arm lifter assembly and the arm tube: it is too short. When putting the cartridge on the LP the arm tube touches the arm lifter (the semi-arc on top of the lifter case) and so it the stylus does not touch the LP at all.
I know (or at least I think I know) all about the exagonal 1/16’’ screw to be unscrewed to rise/lower the arm’s pillar and the other to untighten and rotate the arm lifter ring. So, I screwed the hex screw to rotate the arm lifter ring to the lowest point of the thread which below the arm’s yoke, on top of the arm’s pillar, but the clearance between the arm’s tube and the lifter is still too small to any avoid contact between these two parts.
With that said, now I run out of ideas.

Please, is there anybody out there ( ) who already run into this problem and who is so kind to help me ?
An additional info: in order to correctly set the arm pillar height (it affect the VTA...) I put a small inclinometer on the top of the cartridge shell and adjusted the height of the pillar until the cartridge shell was parallel to the disc surface. Is it correct ? I think so, but prefer to ask.
Many thanks
Luca

Hello and thanks to geof3 and millercarbon ! I would tell you that a solution could be in not raising the arm but lowering it. Since the distance between the edge of the knife (the point of rotation of the arm around the vertical axis) and the arm lifter is fixed, if I rise the arm, I will decrease the distance between the arm tube and the arm lifter. If I decrease the arm height, then the distance between the arm lifter and the arm tube will increase. You can see the drawings at: https://i.imgur.com/IMQEkkq.jpg So, apart form having to lower rather than raising, picking your suggestion there's no way out than to modify the arm's height. This means not having the headshell parallel to the LP surface anymore... and a change in VTA. The point I see is that it is not a matter of the turntable type but if I need to have the headshell parallel to the LP surface (if I need to...) then the SME 3009 lifter will not work properly. So the point is: do you know if the shell has to be parallel to the LP surface to achieve the best setup for the arm or is the arm designed to work with a different inclination of the shell ? This question is rising in my mind ! Thanks Luca |
Hello Mijostyn i already screwed the arm lifter ring the lowest as possibile to the pillar's thread. So I coudl not unscrew more than this... Luca |
