Installing Lugan 3 hp. variable speed motor.
The above post correctly describes the sequence of the install, but I will say, I have been working all day installing the motor, it is not easy, even the prescribed way. First one of the keyways came out when I was lowering the motor and I didn't know it, so when I tried to reinstall the C ring it wouldn't go because the collar was in a bind. I saw something lying on the floor and yes, it was one of the keys, but when I reinstalled it there was no longer a bind and from there on it was fairly easy after having to by a 33.00 set of expansion ring pliers. It is now installed correctly. It would be quite a bit easier with two people, a luxury I don't have. Here are some pictures portraying the install. As it turns out, designing the treadmill motor adaptation was easier then the install of the stock motor on the mill. Thanks for all of the interest, the rest of the adaptation will be coming here shortly.

Treadmill motor powered Lagun mill a success, finished.
:popcorn:[url] Well, the original 1 1/4 inch pulley on the treadmill motor did it. With a 1:7 ratio it now has enough power for the mill. I powered it up today as you will see in the video and it runs fine. Spindle speed is 2000, can go higher, but motor is running cool at that speed. That is in high speed gear also runs smooth in low speed. Here are some pictures of the pulleys, I am using the same type belt as the original treadmill only larger 38 inches. I took the 5/8ths inch v belt, cut and wrapped around the large pulley and glued it with CA. The belt runs nicely on it. I am also going to try to upload a video, we shall see.
