I’m the guy who cut the bad mount off and welded on a more fitting one.

Had the same issue with a 1000lbs capacity “Pittsburgh” stand purchased a couple months ago. The “Big Red” version with the proper fit may no longer be available. Everything seems to be IKON or PITTSBURGH now. HF didn’t publish ID spec for the mount tube. Don’t think QSC publishes an OD for the cradle post either. Did HF change design spec or supplier?

Ended up welding a 2.5” / 63.5mm ID steel pipe, maybe 6” long to the HF beam. 3.5mm difference. Added a 1/8” steel sheet - cut to the ID circumference and rolled up - as a bushing for a good fit.

If you go this route then remember to weld the new pipe 90* to the HF beam like the original mount. The beam is not 90* relative to the stand or floor when bolted to the rolling part of the stand. But the cradle pipe is 90* to the beam. The beam is on an angle which forces the engine / cradle weight against the pipe to keep it stable. This is in reference to the 1000 lbs capacity Pittsburgh stand… don’t know if all their stands have the same design feature. Maybe HF isn’t aware of all their features….
