Building high-end 'tables cheap at Home Despot II

“For those who want the moon but can't afford it or those who can afford it but like to have fun and work with their hands, I'm willing to give out a recipe for a true high-end 'table which is easy to do, and fun to make as sky's the limit on design/creativity! The cost of materials, including 'table, is roughly $200 (depending, more or less), and add to that a Rega tonearm. The results are astonishing. I'll even tell/show you how to make chipboard look like marble and fool and impress all your friends. If there's interest I'll get on with this project, if not, I'll just continue making them in my basement. The next one I make will have a Corian top and have a zebra stripe pattern! Fun! Any takers?”

Here's an idler assembly question. There are these little washers that slip onto the bar that holds the idler wheel. My first question is, are there supposed to be two of them, one on the inside and one on the outside? I have two assemblies and I've jumbled things up a bit, so I forget the way it was originally set up. Also, one of these washers snapped in half. Does anyone know what they're made of? Size? Where they can be purchased? Right now I only have one placed on the inside and I think iI'm getting a vibration that seems to have robbed me of some of the magic.

Thanks,
Glenn

I think we brushed over this question previously.I refer to the bearings in the Lenco spindle bearing.I think that actually they are designed to have a slight play in them if we can credit the Swiss designers with having thought this issue out.I believe that some form of grease was used as the original lubricant and for damping of vibration purposes as well.If a bearing is too tight as say in the Rega table,as many have discovered,it has a lot of disavantages when lubricant is lost.The speed becomes too fast(dry bearing effect)and all damping properties are lost.With the Lenco they knew they were using an oil retaining metal compound and also applying grease.There had to be some way to retain the needed lubricant rather than forcing it right out of the bearing well which would happen in practice.Therefore the give in the Lenco is intented to be there and it is an error to use bushings that are too snug as proper damping and lubrication and speed stability will be lost.Not to mention the wear coming from running on an overly "dry" bushing.

Hi Glenn, there are indeed two little teflon washers, one on either side of the wheel. These silence the scrapings of the wheel, and should be greased on both sides for best performance. Good luck finding one, can't remember if this was addressed over the years.

Glen, I misread your question the other day. I bought some teflon washers that are approximately the same size (ID) from McMaster Carr. I havent had a chance to test them though. Its definately worth a try.

A new white one is born.
It sounds wonderful with the Mayware arm and Grace F-9 cartridge. What a difference VTA makes with this one! That's been a lot of fun to learn and play with.

It is an untweaked L75 that just sits loosely on stilts (screws) on top of a super heavy "sand stone" plinth with some white paint splashed on.

Now I have some fiddling to do with my plastic Technics 3210 + Adcom cartridge to see if it can catch up :)
