Setting up to couple the motors4333 viewsThis is how we setup to couple the motors. Since both ends of the coupler are heated press-fit, once it's on. It's on. Forever.

Coupler almost off3310 viewsThis is the coupler when it's just about cut off.
We would cut down to the keyway in the coupler, then we could pry it open just enough to tap it off the shaft.

Cooling it all off2995 viewsCooling the coupler down to keep the bearings from getting cooked.

Getting the coupler parts off2764 viewsThen we had to mount each of the motors in the lathe and cut the remaining parts of the coupler off the motor shafts. Being VERY careful to not nick or damage the motor shafts.

Putting coupler on 1st motor2659 viewsWe heated the coupler with a torch until it was VERY hot. Then we stil had to pound it down on the shaft.
Not a good sign.

Uncoupling the motors2463 viewsSo, we tried heating and prying to get the motors apart.
Nope, isn't going to work.

2nd motor 2359 viewsThen we quickly lowered the 2nd motor down into the coupler, and once again had to do some pounding.
Another bad sign.

Examining the result2241 viewsHere we are looking at the result, and finding that the motors had NOT pressed far enough into the coupler.
We had a 1/2" of extra space to deal with.
We were going to just add a 1/2" spacer, until we did some measuring, and found that the motors were NOT coupled straight. There was a definite wobble.
