The plinth has been unpacked. Seriously well made by Carl Ellis. I’m looking forward to setting up a cart in the next few days. 

Glad you are enjoying it - Server me well for a few years.

Very happy to spot your FS in Lenco Heaven. Certainly excellent quality builds by Carl Ellis.

This plinth came up on Lenco Heaven in Adelaide and I couldnt resist grabbing it. It looks excellent made from Birch ply. 

 

@SonicArt and others looking for feet ideas. Currently using some Nordost footers which aren’t really designed for a heavy turntable. The Lenco screws down into the two little posts in the photo.

I need better feet for levelling and support.

Gaia 111 are really great feet for BB plinths and good value

I recommend you change to 3 feet rather than 4 - much more stable and should sound better.

 

In my experience you are better to level the stand

rather than using levelling feet.

You want to keep everything under the TT rigid.

 

The Gaia work well under TT's - I have used them to elminate feedback on a Garrard 401 with no loss of energy.

That's actually a very good idea - save some money as well (I was going for 4 feet because the plinth has been set up that way).  I am looking at some machined feet by @SonicArtthat look really nice.  Machined alloy with Delrin inserts.

 

The plinth has been drilled for 4 feet so I would need to find a drill press to make sure the hole I drill is straight.  It should be okay in the middle of the back section.

 

One of the guys on Lenco Heaven thought a heavy plinth wouldn't suit the Gais as too much rubber kills the dynamics and to only use it to damp problem areas.

Here is what I did on my Garrard 301.

I made sure the centre of gravity was within the triangle and nearest to the centre of the triangle as possible  for stability and even weight distribution.

 

Rather than drill the plinth I made 3 "pads" that I used the drill press to insert stainless steel inserts ( 8mm ) and then screwed the "pads" to the underside of the plinth. This way it is very easy to get the studs for your feet dead vertical without having to manhandle the plinth under a drill press.

It’s really good much better than the old stock mat - Oyaide BR-12

That’s great but mine has been sorted with 4 holes and bolt inserts installed. It will be a lot easier just to grab 4 feet from Mark.  I was tempted to go with 3 legs but that requires a lot more mucking around. Plus as well as supporting local Mark’s feet look great.  They should be really stable.

Looks Sensational. Love the plinth and feet.

The latest development includes upgrading my bearing to the long SPH. This took me longer than it should have but after a while the bearing was installed, set at the correct level and fired up. 
 

initial impressions were highly favourable. This is a serious bearing and if it was made by a company with all the marketing and admin costs of one of the big brands it would cost significantly more money.  Sien also makes bearings for Garrards as well. 
 

I was pleasantly surprised as this was more of a try and see what happened after @marcusDsuggested it. The reduction in surface noise was immediately apparent as was the separation of instruments and the bigger soundstage. 
 

Next up will be some feet from Mark at @SonicArt.

Pleased it worked out for you, I have tried pretty much all of the available Lenco bearings ( upgrades to factory and full aftermarket) and the SPH bearing has beaten them all.

[SonicArt]

looks very well made, and from what you said it's very reasonable in price too.

[PKay]

Thanks Mark, the feet arrived today and the quality is first rate. 
The feet look in proportion and very easy to set up. 
 

I’m going to give it a spin tomorrow night. The delrin is very slippery on the high gloss finish so I have left the felt pads for the time being. 

[SonicArt]

a pad I have used is a mix of felt and dense foam,  bunnings has them,  I will look for the pack tomorrow. they stick on so quite handy. The feet look good on the table,  I don't think bigger would have been better...

I might try my herbies fat dots.  I don’t want to be gluing onto the bench. 

[SonicArt]

the little pads stick to the delrin,  not the bench
