    Openbuilds countersink holes are more accurate than China

    Posted by David Suffield on Feb 1st 2023

    I had to replace the c-beam double wide gantry plate I bought from China with Openbuilds double wide plate because the countersink holes on the China plate where not deep enough to clear the low profile bolt heads.
