Almost finished!

Dear All,
We're almost done with our Leslie speaker.
After encountering many problems with our previous sound system, we decided to just start again, with a completely new sound system: a Harley Benton HB40-B bass amplifier. This also makes it easier, as only one rotating piece is needed.
We have worked hard this weekend, and have nearly finished completely. Here are some photos:





Now all that is left to do is the half moon switch for the motor control, the cover panel, and final touches. 
Best, 

Chris M.

Treble array

Hello all,
Last week we finished the treble speaker array. We have 4 tweeters and therefore had to come up with a way of allowing the sound from all four get into the horn that we have made. We came up with an array that then converges into a fitting the same size as the horn.

We've also given the bass and horn rotor a nice black finish after plastering them up to make them nice and sturdy.
Best,

Horn rotor

Hello all,
Marco has kindly built us a horn rotor for the treble speaker. It is unlike any rotor from leslie; instead of having two, with one dummy, it has only one, that is very short, with a counterweight on its side.
Here are some photos of the beginning and the end.

Best,

Power input

Hello all,
We've just finished building the power input to the Leslie, that will work similar to a vacuum cleaner (you pull as much cable out as is needed). We have also dismantled the audio system for our Leslie, but unfortunately, the power button broke in the process.
Also, we finished building the bass rotor which will be used in our Leslie.
Best,
Chris M.

Motor System

Hello all,
We have discovered exactly how the motors of the Leslie work.
The motor is either on or off, spinning fast when it is on (440rpm).
In order to spin it at Slow speed, a metal pin of about 1.5cm in diameter is dropped onto a rubber lined disc that is on the motor. This creates rotational friction that slows the motor down to 45rpm.
We are going to use a different system, made up of gears in order to spin our Leslie.
Best,
Chris M.

Leslie 760!

Hello all,
I am delighted to announce that we have finally found a working Leslie for our project. A fellow in northern Germany is selling his studio Leslie 760 for a very reasonable price to us, and we are going to pick it up on Wednesday the 26th of October.
I would never have thought that even buying a Leslie is a feat in this area. There are people who are willing to sell, but are not capable (either it is broken or too far), there are people who have but do not want to sell, there are people who want to sell, and then suddenly decide not too, there are people who are willing to sell, but at a price much above the norm, and there are people who just don't want anything to do with us. But in the end, patience brought us a great Leslie that will fulfill our needs.
Best,
Chris M.
