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?”

"Has anyone filled in the center-top of the platter aside from the mumetal mod?"

Yes, I have. In fact, I have very seriously modified the top of the platter with great success. It did require modifying the spindle itself, however.

Hello again,

Mine is Delrin plate, but my entire approach to the project was different in that I scrapped most of the Lenco, and designed in the potential to scrap all of it. My view is that the one superior feature of the Lenco is the fact that the idler wheel rides on the underside of the platter, rather than the rim. This opens a myriad of possibilities, including the replacement of the entire platter itself. Also, Lenco's implementation takes stress off the bearing assembly, and opens it to endless possibilities, as well. That one feature is worth the price of admission. The stock motor, etc., are ancillary, and trivial by comparison.

It is the fundamental idea of how the idler engages the platter that makes the Lenco different. In many other respects, it is inferior to some others, but they don't measure up when it comes to the engagement idea. What a point of departure it is for one who is willing to swim in uncharted waters!

Mounted new RB300 w/ Denon 103R. Need advise, please.
Did some tweaking with new armboards. New armboard is approx. 2-3mm below top plate. ***Where is yours?

I played an LP

1. seems fast. Timed it and it is about 33rpms in 56 seconds. However, on this table (Lenco 75/S) the slowest adjustment is 33 and I cannot slow it down. Other table goes down to 16 allowing for adjustment.

2. in the middle of the LP, the stylus skipped, not advancing. I lifted and advanced, the stylus would not drop onto grooves. Could be my armboard is too high (thick)*** I placed another mat on top of the first and LP played all the way through. However, #1 and 3 still a problem.

3. Lots of sibilance, i.e. thick and smothered sounding "s" sounds. Could this be related to new Creek phono stage not broken in. Or cart adjustment?

Digital scale reads 1.6 g tracking force.
Not sure about VTA and cart alignment, just eyeballed.

Any ideas?
Thanks from Oreegunn

Problem # 2 may be that your lift mechanism is interfering with the tonearm. Check to see if the flat part that supports your arm is not bent upward. I am not sure if this is the case for number 1 but the notches that set the speeds i.e the 33 45 78 and 16 on mine can be shifted slightly by loosening the screws that hold them in place.
