Sorry for any confusion and this long post to clear it up.
I provided those links as internet information only. I can, based on my own experience say that the Teflon washers work for me. My advice however is to take all opinions with a grain a salt, unless you know the person well and trust them and know their room/gear. I personally thought it was very interesting on that thread that there were a couple Verdier veterans with differing views on the Verdier setup. One pushed keeping the stock motor which is very good in itself for the application if setup properly (imo - more on this in a bit); and the other just went to another motor and was done with it. Can one or both be wrong ? Well I think both are right because what they did worked for them and they are happy. Nothing else matters really. Right? Its a hobby. I would encourage you to do the experiments yourself with long and short thread, otherwise you will never know the difference yourself. The amount of tweaking this table provides is incredible.
Please understand where I am coming from as well. I will ask you - What is your personal objective in this hobby ? Whether you answer or not is up to you.
My objective. I used to chase my tail changing components. That has stopped for me for vinyl. Now when I want to know where I stand with my vinyl tweaking, I set up an LP and a 15 IPS master tape dub of which I have managed to find and buy a few - of lps I like and own. I start the record with the tape about 10-15 seconds behind the LP. I can switch between the two on the preamp instantly and hear differences in my room. So I tweak my vinyl to get as close to the tape as possible for reproduced sound in my own room period. That is my own objective. If you were to start a post - How many use Reel to Reel as their reference source for reproduced sound? I think you will be surprised how many there are out there.
I can therefore recommend seeking out a pro 15 IPS tape deck and have it calibrated properly. Then hunt down 2 or 3 master tapes to use as a reference. There is a learned technique in hunting tapes. It is a very revealing exercise when you compare 1) 15 IPS master tape dubs and two different TTs using the same tonearm/cartridge on each and 2) tape and two different tonearms/same cartridge on the same table. This is where my opinion (earlier) of my Verdier with the stock motor comes from. I base everything on what I hear not measurements. The day I can no longer do this by ear I will still listen to music - but I will pursue my other hobbies stronger.
The Verdier platform I currently use has been custom made by local Mennonite workers near the area I live in. It is a four foot slab of maple with welded steel legs that has a special shelf underneath on which hundreds of pounds of sand can be loaded onto. So it is a solid stand. As you are aware the type of rack you need will depend on whether your turntable has a suspension or not. The Verdier uses a suspension. Dealing with structure feedback can be done in a couple of ways imo. Some choose to spend $$$$ on isolation platforms. I chose to learn how structure feedback worked and dealt with it my way. If you browse my virtual page I have provided my own findings based on my personal experiences. Look for the tag called structure feedback / spl testing. I should probably update it.
My current pulley to spindle distance is about 24 inches. The dealer I purchased the Verdier from was a veteran owner of many years and he told me he used between 20 and 25 inches. He gave me the tied threads of the various lengths he had tried that he had.
But let me say something that I really feel is important with this Verdier table based on my experience. One of the guys in that thread I linked talked about it too. We all know that wires and interconnects, etc.. affect the sound. Well the thread type and distance is at the source so its effect is multiplied and the final sound will be based on your own gear and your room. So you really need to do the experiments on your own and use what works in your own room.
If you dont have a wide shelf you can mount the motor on a separate stand and experiment with long thread. That will produce a different sound again than the motor being on the same stand as the TT. Remember the TT has a suspension the TT motor does not. The top magnet represents part of the platter on the Platine. Many imo - set up the thread too high. Look at dealer pictures. This is unstable. The thread is best imo set up very low on the platter and set up loose I can flick it with my finger when a record plays. The motor set up in stock form low for leverage not on points. Have you ever tried to move a really heavy couch in your room by yourself? Is it easier pulling it from the top, middle or the bottom of it ?
The above is my current opinion so far and it may change as I live with this table.
Again sorry for the long post. Hope this clears up the confusion. Feel free to pm or ask questions on my virtual page. Have fun.
Cheers
