Tron Rebuild

Tron Rebuild

2005-09-30 by lsf5275@aol.com

Anyone here interested in what's going on with #740? This Tron was apparently torn apart way in the past. The owner at the time decided that the headblock wasn't high enough, so he (or she) completely disassembled the mane frame and re ririveted it. The reason I am describing this is because when they reassembled it, they put spacers in between the frame and the headblock channel, raising it about 3/64ths of an inch. This, in turn, put everything else out of adjustment, and caused the owner to abandon the spillbox cover because the tapes kept scraping against it. Later the current owner made a new spillbox cover with weird little spacers underneath it. I just gets weirderer and weirderer.
The good news is, I have become very proficient with my new rivet gun, and have found many new uses for it (excellent for tongue piercing). Barbells out... rivets in (so to speak).
Anyway, if anyone on the list is interested in following along as I rebuild the WORST Smellotron yet. I am shooting annotated photos as I go, and am happy to share my progress.
I am also working on a somewhat less f***ed up Tron, as well as the very warped keyboard of a another Tron. Straightening warped keys is a challenge.
Since most of what we do on this list is brag or bitch, I though I would share what I'm doing in case there are new owners or others who might have questions about their own machines and want to observe (or participate with their own ideas) in the resurrection of two (+) more Mellotrons.
This one is the most "ground up" job I've undertaken. Thanks to Martin for the Azimuth jobs on the headblocks, and Markus for the SMS 5 cards.

You're a glutton for punishment aren't you, sir? :-) Are you going to post the pics on your site as a cautionary tale? Actually, if you find a good way to de-warp keys, a friend's machine could do with being treated in the same fashion, so I'll be following your progress with interest. And good luck... :-)

Frank,

I, for one, am interested. Where are those pics?

Mellotron dentistry...

2005-10-01 by Jack Younger

Hey!
Key straightening is pretty simple in theory, but
a long careful process. Anybody needing advice can
contact me here and I will gladly take you through it.
You'll need a few things: A decent heat gun, some
good woodworking clamps, about $5 in pennies (loose),
a plastic bag and a lot of patience. The pennies and
the bag are used for an adjustable weight source.
You'll need to do repeated treatments over many
days/weeks, but it's worth it. Markus turned me on to
the method and it's quite sound. EMI103S was a
craggly, twisted monstrosity, with keys rubbing and
catching on each other and now it's as good as new!
I can't stress enough, however, that it does
require some definite skill and a familiarity with the
basic properties of wood. Do Not attempt to mess with
your 'tron keys unless you know what you're doing.
They can easily be irreparably damaged.
Cheers!

There's a very easy way to get warped keys straightened: find a good
piano technician, not just anyone, but one whose reputation people
vouch for, because Jack is right. You can severely mess things up.

A piano technician is trained to do stuff like this and a lot of their
repair time (as opposed to tuning) is spent regulating keyboards. It's
well worth spending the money and having the job done correctly.

Just my opinion...
