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?”

You would think the spelling would have been corrected in the thread title for VII, if this is indeed an upgrade ;-}}

Hi Everyone,

This is my first post, and I thought I'd managed to get hooked just as the thread disappeared...

I've got myself a LEAK delta version of the Lenco, metal idler wheel and all. I've made a new (very ugly!) plinth from left-over chip-board and pine, but I just can't stop the motor vibrating. I've cleaned and re-greased the bearings and bushes at both ends, and tried to get the spring-loaded screw just right, but no good. The 6 mounting springs seem fine too. Any ideas?

Hi Fishwinker,

It seems you are the point where you’ll need to adjust the block that surrounds the armature.
1- Remove the motor from the Lenco and place it on a resonant surface (I find Styrofoam shipping block to be excellent).
2- Hot-wire your motor’s AC, but don’t plug it in yet.
3- Remove the back plate so that you can remove the armature.
4- You’ll see four Philips head screws on the block – break them (the crack of loosening for the first time in a long time). Retighten to “to snug” all except the screw in the 4:30 position as you look at it head on. Leave this one a little looser since it’s hard to get at with the armature remounted spinning.
5- Remount the armature and back plate.
6- Plug in the motor.
7- With the armature hopefully spinning, back off on the three accessible screws until you can move the block orientation.
8- Adjust till you get smooth running.
9- Tighten up the three screws then unplug the motor.
10- Use a 90-degree Philips head driver or a tiny Philips screwdriver to tighten the last screw. You’re done.

I'd add that you need to first check that the wiring is correct (and of course the red transport screws are undone), as noise and vibration is a sign of improper wiring as well, in which case adjusting the armature (which is a very good idea in its own right) will not work. Since you have a Leak, it appears you are in Europe, and if not in Europe, then you need to check the wiring anyway. Good luck!

Jean,

Where are my manners? Thank you for the very kind words, and as I wrote you in an e-mail, it’s what any Lenco renegade would do – but, perhaps a bit too renegade – in that I’m not all too comfortable fielding the header responsibilities with all of this (e-mails and tech queries) – I’m still a novice in some ways and you’ve got the full grasp of the global picture here.

Let’s hope that the restoring of the old thread is in sight at the good offices of AudioGon and that the confusion being experienced by newcomers will end.

Sail on, Admiral Nantais!
