I want to add 2 knee levers to an Emmons GS10 student model. Questions:
1. Do I need special knee levers, or will any kind be OK?
2. What parts do I need to do the job? I have nothing yet.
3. Where do I properly place the levers? (diagram needed)
4. Any Suggestions and offers appreciated.
5. Have I forgotten anything??
Thanks, Fred

Hi Fred.
Post pictures of the undercarriage so people can see and make suggestions. Just a thought. Good luck buddy!

Paul,
Sorry, but I don't have a way to do that. Fred

Re: Knee Levers
The actual knee levers don't have to be Emmons, but the bits that are connected to the changer, which is a push pull, need to be of similar dimensions to what's already on there, as some rods pass through more than one bellcrank.
Depending on what raises/lowers you're going to put on there, you're going to need bellcranks, half-tone tuners, pull/push rods, maybe some little wire hooks that connect the pull rods to the changer fingers (if you're raising), shock springs, collars, 2 cross-shafts, and maybe some spacers that go on the push rods, between the finger and the collar (if you're lowering).
Knee lever positioning depends on your preference, I always try to put an aluminium plate (about 1/4" thick) in the approximate mounting area (using any existing screw holes that might already be in the body) and mount the knee levers to that plate.
If I get the positioning wrong, I'll move the knee lever until I'm happy with the position.
If the aluminium plate looks like a piece of cheese, with tapped holes all over it (from unsuccessful trial-and-error knee lever positioning), I'll just throw the plate away and start again, with no damage done to the PSG.

Read and heed Burt's last two paragraphs! The location of the levers need to be in a position where YOU ARE COMFORTABLE! There's no sense in undergoing surgery to add another joint to your leg just to activate a pedal and lever simultaneously. Try sitting at the instrument and note where your leg passes under the rear apron. Project that position into the instrument in order to get a ball-park location.
Then read Burt's last two paragraphs again!
A word to the wise should be sufficient.
