Building high-end 'tables cheap at Home Despot II

Hi Fishwinker,

Been brooding about what could be causing your motor vibration ... and I'm still brooding ...

In the meantime, take a look at 4yanx's post from a while back and see if it applies.

"As a further aside, we've found that the proper "tension" placed on the nose end screw is such that it the cupped end just seats onto the end of the rotor spindle and allows free travel of the "springy" doo-dad (less than a millimeter). Too little tension causes slop and too much causes restriction. It is a very fine line and impossible to "see". It helps when you get it right to have one person hold the motor casing with one hand, and a small screwdriver set in the slotted end of the screw with the other, while a second person FIRMLY tightens the hold down nut. In our experience, tightening that nut otherwise almost always results in the screw tightening a bit along with it and mucking up the works. Too, if the nut is not secured tightly enough, it backs off - the screw along with it. On out first couple, the doo-dad was so frozen that we didn’t even know it was supposed to “give”. Getting the proper tension was a BEAR until we discovered that."

Is there a numeric designation on the GL Delta Lady?

Hi Mario,

Thank you very much for your continuing support. I've been listening to it as-is a lot today, and I love it. However, now that it's running, I've realised that it seems to be running too fast - the slider needs to be a lot closer to 33 than 45 when I'm playing a 45. If there's nothing wrong with the motor, and unless something very strange has happened to the electricity supply, I'm thinking that this must mean that the whole rotor/cone assembly is too far towards the nose bearing. I'll try adjusting the nose screw again tomorrow, but I honestly couldn't find any particular point at which the vibration reduced. It really is quite pronounced, and you can actually feel the plinth vibrating when the motor's running(the transport screws are completely free and the motor is suspended freely on its springs).

Hi, Fishwinker,

Another suggestion, I have run into a Lenco that actually had the cone assembly bent so that the rotor/cone assembly wobbled sideways, which also caused the idler wheel to wobble back and forth. To diagnose this, take the platter off, tun on the motor and see if there is any wobbling in the idler wheel or rotor/cone. If so, unless you can manage to straighten it out, you'll probably need a new motor, unfortunately.

Hi Fishwinker,

From your wiring above it seems like you have a European motor set for 220v. What is your local a.c.?

Is the Lenco in it's original plinth, with the springs intact?

Have you removed the motor to test on the bench? Did it still vibrate badly?

Apologies if you've mentioned this already, just trying to catch up.

Regards

Well, I decided to visit the good offices of AudioGon this morning which happen to be in my hometown, at least, the nuts and bolts part of the mission. After getting over the novelty of a virtual member dropping by the virtual mothership (a first, I was told), I had a pleasant chat with the moderator on duty.

Sadly, it appears, that despite gallant efforts, the old “Despot” thread has not been found and the likelihood of its recovery is growing doubtful. It also appears that the new thread will continue to fall under AudioGon’s now universal policy of moderator review on all postings.

It is my belief that AudioGon should not be second-guessed over exercising their prerogatives in this matter. We’ve had a long run and AudioGon has provided an excellent platform to allow us to have our unfettered discussions.

It is about how and whether this run should continue that we should now calmly reflect on.

My case for pressing on, is rooted in a meaning of continuum – to flow like an uninterrupted river with tributaries and distributaries. People get on or off at their pleasure – but this “old man river” needs to keep rolling along for many of us. The alternative, I fear, will be the occasional Lenco/Idler related post that will be short-lived and thin soup because of its fleeting nature and lack of full, round table discussions. The “Despot” thread has been a Kiosk and it is ours. We’ve known it would be there as surely as the rising sun, and it has allowed us to build a hobby into something a little more special. It has been the long term camaraderie, I believe, that has lent it that special luster – allowing people to check back in, catch up and be genuinely welcomed.

By the way, welcome back Bornin!

My selfish stake in this is only wanting that continuum. There is no stake for me as being “the leader of the pack” – because I’m not. I just happened to restart the thread because of desperation over its absence, an act that I’m beginning to regret. There are others far more knowledgeable than I.

But as Jlin has demonstrated, there are archives that can be called on, even if some of that knowledge base has elected to depart, for the time being, over the unfortunate, yet understandable row that has developed.

About that row, I will only say this. Jean’s control had its purpose in establishing the discipline over his innovations as he (and most of us) applied them to the Lenco. New innovations by new originators have, at times, been encouraged, cautioned or discouraged, under Jean’s close (too close - for some) tutelage. The results of these innovations have sometimes been applauded and sometimes ignored. The course of human dynamics of the whys and hows in all this is too great a minefield to warrant further treading. But I’ll only add this: Innovation is what the original thrust was about – and it should continue to have its day in its furtherance.
