Internal Leslie to freestanding Leslie

[Papabooly]

I'm taking a leslie rotor speaker system out of a late model Hammond spinet and putting it in a cabinet. Has anyone done this?

ive got a leslie setup that i yanked from an old organ . ive been thinking about doing the same thing ... and im sure someone else somewhere has allready done it ...

i was thinking that the cab should hold the unit as it did in the organ , so as not to mess with the tension and so on of the belt drive . i also pulled the power amp from it and was going to use it as a powered cab with the 2x12s and leslie setup like it were, was, t'was, in the organ (would also allow me to control the speed of it and such) .

i guess it could depend on what sorta setup youre gonna use it with ? me pesonally , i just like to make a lot of noise .

might wanna consider center of balance ? even though it could be neat to see the cab dancing around on stage like a drunken barfly ... til it crashes into something expensive

I've got my cabinet built, but might make some adjustments, I kinda like that dancing cabinet image.

Would you use the controls from the old organ or come up with a simple new circutry? I haven't been able to come up with a scematic of the original organ.

when i gutted the organ , a Conn from '81 , i pulled everything and traced the wires to the switches , knobs , etc and took some notes . unfortunately the notes dissapeared during one of my 'one to many moves' , and thats the real reason i havent done anything with it yet , that and the wire runs were held together with electrical tape ... ever tried removing 20+year old electrical tape ? ... everything it touched was left unmanagebly sticky ...

if i remember correctly , the leslie had an on/off switch and a knob (pot) for speed control . i think its just adjusting the amount of juice to the motor for speed and amount of signal to the speaker for volume . wouldnt be hard to figure out a real basic control circuit for it . theres alot of info around the web on leslie stuff , probably many o diagrams for simple controls too .

even though it started as a joke , it would be funny if this thread turned into a 'dancing cab' thread !
i bet noone else on this forum has a dancing speaker cabinet ... and if they do , please step forward !

Ya got my wheels turning now!!! I picture a lightweight cabinet (pressed foam board) and carrige, mounted on feet with springs and syncronized volume and speed control so that it will dance more the louder you play. Now I'm already looking for another doner organ to get another leslie.

here is a picture of the one i did a while back. i have since named it "reslie" and added a name plate on the upper left corner. it needs a new belt. the one it has is starting to dry out and crack so i twisted some string around the crack and coated it all in silicon. which has kept it from breaking but, makes a bit of a thud are it passes on the pulleys.

oh and here is a gut shot i just found.

Wow, sweet. Nice job. What did you get the components from? Mine has a stationary speaker and a rotating drum to direct the sound. Can't tell from the pics if you have an internal amp. Looks like yours will provide some large sound.

it came from an organ. i can't remember which one though. yeah on mine the speaker rotates which helped with keeping it on the smaller side. i wanted to be able to use the speaker cloth from the organ so i had to keep it small. i also for whatever reason decided it should look like a piece of furniture. i did it just for the heck of it so i built it quickly and easily.

it's only a 6x9 speaker so it isn't too loud but plenty loud enough for recording and messing around. i don't have an internal amp. just an slow/off/on switch. one cool thing is that there were 2 of these speakers in the organ. one at 4ohms and the other at 8ohms which is nice.
