Hello! Apologies if i'm posting in the wrong place.

I have a Mark 1 88 key stage piano that's been sitting in it's case for some years.
I'm planning to do some maintenance, but it seems i'm missing some parts to make it stand.
Wanted to see if anyone has any stuff they'd want to sell before i go to Vintage Vibe.
I'm in need of the following:
1 front leg
2 front leg couplers
1 cross bar knob
male sustain rod part(the part of the sustain rod that interfaces with the pianos sustain mechanics)
some rubber feet, current feet are a bit worn.

My 10% expired today :'(, can I have another?

The cross-bar knob is simply a 1/4"-20 threaded knob.  I think I remember that the threaded portion has be be longer than you expect, like an inch and a half.

Hey, thanks!
Are you sure it's 1/4-20? that seems a bit small.*
I've been meaning to take measurements and order some things from McMaster.
This looks a bit nicer than the plastic: http://www.mcmaster.com/#6042k86/=14dbazt
I also got some steel shaft for linear motion which I'll be using for the sustain.
Also McMaster: http://www.mcmaster.com/#6061k425/=14dbdnj

Further more,
here are some none-skid tips that will work for legs: http://www.mcmaster.com/#2517t82/=14dc0i0
here are some cheaper ones on amazon: https://www.amazon.com/gp/product/B00004YOFZ/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

The rubber feet which thread onto the rear legs look like either 1/4-20 or m6, can you tell me which? **

*edit, sorry you're right, that's 1/4-20.
**got home and measured. seems everything is standard(not always the case).

I'd be careful with this one.  A three inch shaft would most likely have to be cut as its length is likely to hit the piano's internals.

I think I'm going to jump on some of those leg ends though.

Thanks,
Ray

Oh man, yeah, good catch.
I actually went ahead and used a caliper to measure the depth of that hole, came out to just about 1in, so with the crossbars in place something with a 1in stud would be perfect.

Here's a correct version of what was posted: https://www.zoro.com/innovative-components-star-knob-1-1-34-in-14-20-3gep2/i/G1399282/

I recommend putting some washers in the bottoms of those rubber caps to help them live longer.
Also, there's these leveling mounts that can be used for the rear legs: https://www.zoro.com/s-w-level-mount-swivel-stud-14-20-1in-base-bsw-0z/i/G0271092/

Here are a couple of photos of my Rhodes: http://imgur.com/a/VKdXf

1977 Rhodes Mark I 88. From my understanding this piano is all original, and has been sitting around for pretty much it's whole life. Sounds awesome, other than some tuning and some of the lower keys being a bit quiet.
I also had to remove the harp, as the dampening panel for the sustain was not set on the pivot pins.
Anyone know if it's common to do this while storing?
Also, the sustain action is not totally even(ie some rods dampened before others). I'm assuming this is due to the dampers not being totally even. Could someone provide some info on this?

To anyone curios, here are all the parts I used to get it standing again:

Cross bar knob:

Feet for back legs:

Linear shaft to interface with sustain lower half of the sustain rod:

I bough a 1/4" for this, i'd recommend going smaller, as the 1/4" is a bit too snug.

Thanks!
