Walker Prelude Quartet users with VPI 16.5

Mucho good advice so far.

Agree that considerable downward pressure from brushes while the platter is spinning, will cause more drag, and no doubt cause increased platter motor heat.

A cooling fan mod will solve that.

Me, I generally apply fluids, with platter rotating, then once the record is covered, I stop the platter, and give those cleaners some time to do thier job. I'll very lightly-gently scrub the record in sections with the platter motionless.

A spare wand dedicated for just the final rinse step I think is a good idea. I have hear some going to the lengths of having a different wand assembly for each, and every step, but I think this is a bit overdoing it.

I myself, notice what you say about platter rock, and have recently considered replacing the 4 rubber standoffs that connect the platter motor, to the motor mounting plate, with either aluminum spacers, or nylon.

I know places like the home improvement stores carry such in their hardware sections.

I feel if there is less rock-play, the vacuum wand will be able to maintain a more uniform contact across the record.

Whatever the standoff's lengths are, the new spacers would need to be the exact same length, so as not to alter platter height. Mark

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.

Theo,
I've discussed these seemingly strange heat issues occuring with some of the VPI 16.5's with numerous folks, in a number of forums.

It seems a mystery that some experience it, and some don't. In any case, I don't believe Harry Weisfield had marathon cleaning sessions in mind with the 16.5. At least not in stock form. No doubt why the more expensive offerings do have fans.

Harry recently commented about the 16.5 in one forum, saying that the vacuum motor has been the same for a long time, so, the only other variable I can think of, is the platter motor.

My own 16.5 displayed a very hot platter motor after short usage, and hence, I installed a cooling fan, and it has helped considerably.

Whether some motors were a different model, a change of internal design, or other issues, such as inadequate gearcase lubricant where the motors were made, I cannot say?

The slight bit of rest in between steps helps, but the 16.5 doesn't possess much in the way of cabinet ventilation to let heat escape.

I think all will agree that even the finest cleaners need some time to do their jobs. An instant on, and off doesn't give any cleaner sufficient time to properly work. I see no benefit though, letting a rinse step sit for a prolonged period of time on a record.

A rinse water I usually apply, spread the best I can, and take off quickly. If I feel there might still be remnants of cleaners left behind, I simply repeat the rinse step again. Mark

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.

Hopefully the moderators will let me post this link, which is an article I authored some time back. Hopefully this will save some bandwidth going into too much detail here.

My methods, and procedures are but one way. I trying thinking as logical, and keeping a professional frame of mind. As mentioned, a switch could've been utilized.

And while the particular fan I used may not be any longer available, a similar sized fan, with similar wattage consumption, and CFM rating should be no trouble finding.
