Walker Prelude Quartet users with VPI 16.5


I have been using the Walker Prelude system with my VPI 16.5 for about 2-3 yrs now. I have been happy with the end results, but I have a few questions to ask for anyone using
the same combination. One, is how many LP's do you do in one session? I like to do the 1/2 mix and get about 8-10 Lp's in each session. But those of you using the 16.5, how hot does you RCM get? Also do you use seperate vacuum tubes for each step? I use 2 tubes one for step 1 & 2 and the other for 3 & 4. How wet do you get the LP for each step. Also for all 16.5 owners how much "wobble" do you get on your platter? Mine seems to move (up and down not side to side) more as the session goes on. I spoke with Mofimadness about his and he states his older 16.5 has always had some wobble to it. But I notice that as the machine warms up it increases to the point that if I apply scrubbing pressure 180 deg. from the vac. tube it can actually lift the vac. tube enought to lose full contact. Once the machine cools this movement is considerably less. Any feed back will be helpful and appreciated.

Thanks for your replys. I am as you suspect cleaning with the record spinning, and it does make complete sense to me now that I am causing the motor to overwork and produce more heat. I think you have given me a solution to look into. It never occured to me to scrub with the platter stopped. Markd51, I was one of those that had 4 wands and recently reduced it to two as it was just to time consuming and confusing as to what step I was on. The motor mounts is something I will look at, good advice, thanks. I do use the MoFi brushes and like them better than Walkers. Sbank, I tried the Vortex and was not pleased after 2 phone calls to Lloyd on set up and a concern about scraping along the vinyl, I gave up and got a refund. I think it wan't well received since it is no longer offered. You must have set yours just right to get good results, I think it made great sense in it's design. But executing it in the field must have been too difficult as the dealer I returned mine to, said he had most of them come back. Thanks to all I think you have me going in the right direction on solving the heat issue and the wobble.
I had also thought of a cooling fan, but maybe these suggestions will avoid me doing that.
Markd51, the more I have thought about this I think that a cooling fan is in order here. When you installed your fan did you cut any additional holes for added air movement?
And did you add the fan and a switch or just wire the fan to the motor?
Thanks for you help.

Thank you so very much for this information. It will be very helpfull in solving this issue. Replacing the platter was a good idea too. My thought was to install some rollers underneath to support the platter, and with the acrylic platter you used that would provide a smooth race.
Very good ideas indeed.

I had actually though about calling VPI about buying a cooling fan, but they are out till May. I will investigate into the platter as well. I have adjusted the wand as I use a LP12 felt mat on mine. I have removed the platter and think I can fabricate a roller support system for either this platter or the acrylic. I see what you mean by the motor supports, that solves my mystery as to why it wobbles more when hot, the rubber is softening with the heat. I am looking forward to fixing this once and for all.
Thanks again for all your help.
