Looking through Google Images for a suitable electric motor test set up, I came across a member of RC Groups (Sandancer) who recently purchased one of these:
Infinity Hobby
There is also an upgrade to enable larger motors to be tested:
Infinity Hobby
The test bed has a capacity of up to 30kg of thrust enabling a wide range of motor/propeller combinations.
I have no idea what that is in Imperial, but the electronic scale used in the test bed can be selected for ounces and pounds.
Here it is in use shown in Sandancer's blog:
