Cartridge Force - Is a Little 'Over-Force' Okay?


With kids getting older and not as 'grabby', I decided to dust off the Pro-Ject 1.2, and throw on a new cartridge (Sumiko Olympia), replacing the 25-year-old Oyster. After dialing-in the cartridge to its recommended 2.0 grams, I noticed the tonearm counterweight keeps the lid/dust cover from closing. With kids around, I'd really prefer to keep a lid on it. If I move the counterweight to a position where it doesn't interfere with the cover, it weighs-in at 2.7 grams. 

My question is, does .7 grams, with this particular cartridge make a difference? Not just in sound quality (I couldn't hear the difference), but in the case of preserving the longevity of the vinyl. 

Or is there a compatible counterweight that would add a few more grams of force? I was trying to justify a whole new rig, but this little guy still (seemingly) works just fine.

+1 @larryi   my idea too.  Can find suitable small piece of metal and stick with Blutack.

In the old days we used to just tape a penny to the headshell and call it good.

@clearthinker, absolutely, it is called a "tape weight" for balancing automotive wheels. Any auto shop has them. He can place them on the bottom side of the counter weight were they will be hard to see.

It's probably easier just to make some small spacers to hold the lid up slightly when not playing records. The deck might well sound better with the lid open when you are actually listening to music.  I would not track a cartridge at close to 25% over the manufacturer's recommended downforce.

@mijostyn   I think that may be a bit gross for this application; I recall they cut them in 1g and 2g pieces.  But they can be cut down easily with a hacksaw or even a blunt knife as they are made of lead..
