Linn Bedrok LP12 Plinth Upgrade

watch the video

https://www.youtube.com/watch?v=SqP4eHBSlI4&t=2s

minute 5, the shaft simply drops into the bearing with no resistance

clunk

he removes it, adds a few drops of oil, it simply drops in again

clunk again.

There is no way in the world that that can be considered fine tolerances. and what makes the clunk noise? shouldn't it be zero contact floating on oil?

minute 6, drop the tonearm post in the mount indicates no close fit either.

This video is shocking. The guy has no idea of how to put a turntable together.

Not only is the bearing housing and shaft as loose as a goose,

 he puts no oil on the spindle before insertion.

In tight tolerance bearings you always smear oil around the spindle before insertion to avoid scouring when inserting.

Unbelievable - and the video reminds me of what a rube Goldberg contraption the Linn is along with the low tech bearing and motor the size of a weenie.

@dover

The guy is Gordon Inch at Linn. I found him to be very approachable.

He’ll no doubt be interested to hear your views on turntable set up.

Let me know how you get on.

@newton_john Tonight I asked a well respected mechanical engineer if the Linn bearing that Dover and others claims is not put together accurately, is in fact that. The gentleman told me that clearly the folks denigrating the Linn bearing design really do not understand how this particular Linn bearing functions.

Dover and the other naysayers clearly have a lot to discover...as you are pointing out.LOL.

@daveyf

Thank you.

In the days before social media, we used to think every village only had one idiot.

@daveyf 

It's basic engineering - you always put a smear of oil on both parts - housing and spindle to avoid scoring. If you rewatch the video when he first puts the spindle in the first time ( with no oil on the spindle ) he puts it in on an angle - scraping the top of the bearing housing.

I rewatched the video - few other items of concern

He drops the tonearm with delicate bearings straight onto the hard surface of the table - you can hear it clunk as he clumsily puts it down. I always place arms on soft pads to protect them.

Then he checks the vertical tracking force with the arm out of level. Most folk on this forum know that the tracking force will change when the vta is altered.

He should be checking the tracking force when the arm is level.

I also notice that when he checks the tracking force he manages to drop the lid and send it across the deck and almost wipes out the cantilever.

If this is the top Linn guy so be it.
