Yeah, that distance is accounted for with the angle iron I will be attaching to the unistrut in a similar way as @mrfugu’s implementation here UniStrut Frame designs
In my case, there will be angle iron attached to the front face of the unistrut, onto which the bracket will be mounted.
This is likely easier drawn, unfortunately I am not at home with access to Autocad at the moment. Maybe this will suffice:
Where the yellow is the framing, the black is the unistrut, the maroon is the angle iron, the green is the motor bracket, and the purple is the motor.
That said, I suppose it does depend on where the balance point of the sled winds up, but since I am planning a steel sled, I am hopeful that the balance point will end up being not more than a couple inches from the work surface, in which case that setup should work fine.
Out of curiosity, what kinds of balance distances in the z-axis are people finding?
I am anxious to get it put together, unfortunately full time work and commute coupled with small kids and all their activities doesn’t leave a lot of time to tinker in the workshop.
