I have also added a Joly-on bearing,
Thank you so much Nic. It took me a long time to work it out. I had to modify the motor so it would fit in a slightly smaller hole so that there was enough plywood left to bolt the bearing housing into. The bearing housing is fully enclosed within the plinth so is structurally solid and fully supported. It was difficult to achieve. I'm just about to put the other Lenco back together so I'll post some pics of the rebuild later today with a bit of luck. The pics will show the modified motor, bearing housing and top plate mounting.
Thanks Chops, I took a little inspiration from one of your builds, I made up some plastic washers to lift up the top plate so the lip is not not sitting on the plinth then cut up an eraser into four pieces & placed them between the corners of the top plate & plinth to provide some damping.I'm impressed Tony

The top plate is still screwed to the plinth by four screws in the bowl of the top plate, I have just used plastic washers to lift the top plate slightly so that the lip is not quite contacting the plinth as shown in Chops54s pics further upthread, I have placed the erasers in the corners of the top plate to prevent any potential ringing. I am new to this & realise I may not have done things entirely by the book but it seems to work just fine.If I am reading this correctly, you have put some erasure rubber between top plate and plinth (and called it damping). But what you have done is isolate the top plate (et al) from the plinth, and unless you have added some kind of damping to the top plate, then you may have made things worse. The top plate is not known for its damping ability.
