Clearly these aren't start/run motors, but I'm trying to decide whether or not its an actual two speed motor set, chorale and tremolo. Anyone familiar with the Hammond Regent/know if it had a two speed internal Leslie?</P>

This construction looks strangely odd to me... but it has two motors on it... see the motor laminations? One above the wheel with therubber tyre and one below? A big 'un and a small 'un? so it's definitely a two speed.</P>
I think the oddness is where the ridged drive wheel is... it's in between the motors ON the wheel with the tyre, instead of below the Fast motor.</P>
This means they mount IN rather than ON the board, with each motor either side of the board.</P>
One advantage to the DIY Leslie approach is that you can split the power and audio input. I'm definitely going the 1/4" route so I can get a guitar effect like that one out of it. And 200 watts = KILLER! I'm going to try to find a really powerful solid state amp for my Leslie so its as loud as possible. Those compression drivers I linked you to on the other thread are supposedly 500 watts RMS...</P>
I'll definitely be needing your help when I get my motors together for this relay and speed switching stuff. It's great to know that someone such as yourself has already done the hard work and pioneered a truly DIY Leslie from pulled organ motors--I think that's one of the only ways to really do it and hope for a chorale/tremolo effect, unless you buy expensive brushless DC motors for which you can vary the speed.</P>

I avoided the relay route last time because of cost, and just switched the straight 240volts direct like we do every day when we use a light switch!</P>
Chris Clifton on Hammond Zone did draw me a very good plan though, and now I'm putting this 90W amp into my Frankenleslie I have tolook atthe relay thing, cos it's already got one built into it. I just have to figure out how to use it!</P>
Man, this past 8 months of owning a hammond has taught me both electronics and woodworking!</P>
I haven't tried to fix our car port yet though, but I may now have the skills for it....</P>
I wired it backwards so it tells me NO instead of ON!</P>
Its a DPDT or double pole double throw switch, this means ithas six pins, orthe same as two separate switches with 3 pins.</P>
The middle pin is "ground" or neutral as we say in english countries, whilepin1 is power to the fast motor, pin 3 is power to the slow motor, when the switch is in the middle it cuts power completely.</P>
The reason why I havethe secondset of pinsin there is becauseMy frankenleslie is made both from a 240V motor set..... and the Bass rotor is the leslie from out of the T500 itself..... which is secretly, inside, a117VOLT SYSTEM!! Which means it has to take power from the organ, and the switch instead activates the organ's existing relay switch...</P>
When I put in this 240V power amp I'm in for a bit of a challenge regarding this issue!</P>
Did you bid on the Hammond Regent motors, Red? I saw there was one bidder this AM. I was tempted to when I first saw that myself earlier this week, but before the bidding is over they are usually up over 50$ so I passed and got the slow motor instead. Looks like a decent deal!</p>
