Alcohol / Pinchrollers

Alcohol / Pinchrollers

2007-11-24 by Hessel Herder

Hi all,

I just installed the new Streetly frame into my M400 and am now in process of realligning te pressure pads / pinchrollers.
The old original tape set just needed too much 'push' to make them play ok

I already gently oiled some of the pinchrollers which stuck,that seems to work fine.Can I clean the rollers with alcohol or would that ruin them?

Cheers,H

Most of us drink the alcohol and wind up forgetting about the mellotron for another day.

But the the next day tho,hung over and set to sort out the Tron ( as if one could )

In the studio it used to be practice not to clean the Studer rollers with isopropdyl /alcohol as it made them swell / uneven.Not sure if Trons use the same material for their rollers

Regards,H

That's what I've always used. Fortunately, I never got the two kinds of alcohol confused.

Gentlemen, any other liquids our esteemed colleague should try?

Caveat: make sure all the excess oil is wiped away.  Tapes don't like oil.  The alcohol roller dip is quite acceptable (and preferable).
 
You may want to consider slightly catilevering the edges of the rollers.  They tend to wear concave with age.  Cantilevering provides a better surface to grip the tapes and reduce the possibility of tapes being skewed (and skewered).

If you must use alcohol, denatured alcohol works fine. Oiling pinch rollers is a temporary fix, at best. Oil attracts dirt and the rollers eventually stick again. I usually pop the roller out of the key spring (carefully) and clean the axle with a Dremel tool and a wire wheel. Then I clean and deburr the inside of the hub until it spins freely on the axle. I then reinsert the axle and roller into the spring. and re-peen the axle ends. This is a permanent fix. The roller will never again require oil.

Hi Frank,

I have used WD40 on making pinchrollers spin again.
Once treated as such,will your way of cleaning them avoid any possible attraction of dirt?

WD40 will dry out in a days, if not hours. It's a short-term solution
at best.

If you want a slightly better alternative then try Servisol which
appears to last much better.

Can you use Graves 190? Whatever's left over could then be mixed
with beer and punch for a little Hop, Skip and Go Naked.

An odd request, but why not? I'll trade you some for a couple of new
tape frames. Let's see....Mk II 3 violins, flute, and Tenor Sax on one
and M300b, Oboe, and that new vibrato-y Cello on the other.

Any fluid you use to lubricate pinch rollers will eventually make them worse. The only proper way is to remove the roller, polish the axle, hone out the hub and reassemble. There is nothing on a properly cleaned and restored Mellotron that needs oil except the motor shaft where it passes through the bushings.

Hello-
I agree that oils should be avoided in lubricating
the 'tron. But, penetrating oils (like WD-40 or
3-In-1) and silicone based oils, should be avoided
completely. Even though they can evaporate, the
solvents in them tend to make things dissolve
unexpectedly, or soften. If the oil gets into a pinch
roller, god knows what could happen to the tape.
Silicones tend to bond to metal and electronics,
changing their characteristics. It is very hard to
completely clean off. Get silicone oil on a circuit
board, and solder repair can be damn near impossible.
If you feel oiling needs to be done, use a pure fine
machine oil, with NO additives.

That shit is a mess. Every time I use it, it ends up leaking back out all over the place. My oiler has a long spout, but still, a few minutes after using it, towels are required.
 
 
However, oiling is fun.

Unlikely in this case, but be proud of your oiler. To lose it would be devastating.
