Hi guys , I'm putting together a custom LP12 and am wondering if anybody out there has the exact measurements of the corner bolt hole placement above where the motor is mounted on the top plate in top left hand corner. it goes through and attaches to the corner bracing to prevent plinth rattle and enable a snug fit the top plate. Also what size bolt is used i.e. 5mm ,6mm, M3,M4 etc??? I have looked endlessly online but cant find any genuine linn info, only peoples own mods.
My top plate wont be arriving to oz for a couple of weeks but would like to get the hole drilled in the corner brace of the plinth thats secures the plate.
If anybody out there has an lp12 that can measure in from the side and back of top plate it would be a great help. hopefully one of these images works. still haven't quite figured out how to post them yet
Thanks

Hi Karl
There are 5 large bolts on the top plate - and 2 smaller ones front and back as well as a grub screw near the motor and 2 coming from underneath where the belt runs through , as well as 2 for holding the motor
do you mean the larger ones around the top plate, I will describe the motor ones, hopefully that gets you started.

The 2 motor bolt holes are diagonal opposite each other so two measurements - in fact 4 are needed to define the diagonal A. 111mm locates the bolt that is from the plinth rear outer to the hole closer to the outer frame
and B.69mm locates the bolt that is from the rear plinth - that hole being closer to the armboard than the other, and to define further relative to the side from the side furthest from arm board - same point as A above is 71mm
from the side of the plinth, and B above is 111mm from the side. The Plinth is 22mm thick. As for bolt size it looks very close to M3 - but is a high tensile allen key type Also noted there is adjustment of about 5mm on a diagonal
like a key way for placing the motor, so it is positioned I guess relative to enabling the motor pulley and given final tension, once the motor pulley functions correctly.

Hope that helps

Cheers / Chris

Hi Chris thanks for the reply, its the bolt in the top left corner of the plinth behind the motor and belt guide holes.
it goes through the plate and corner bracing of the plinth to stop any plinth rattle.
I know the older plates didn't have it but the newer ones do.

Hi Karl
My model is missing that one, the nearest I can see to the motor and belt guide is the grub screw
That one is 77mm measured from the rear plinth, and equally 77mm from the side plinth,
Its also about M3 maybe a tad smaller, and on mine has a medium thread.

Cheers / Chris

Thanks Chris I've added a url to a photo in my original post (hopefully it works), I have a suspicion its somewhere around 33 or 36mm equidistant from both edges but want to get it spot on so I will carry on the search and hopefully somebody will save the day.
thanks for your time buddy
