💡 What steps ensure correct threading when mounting custom table bases? Clearing oxidation off the contact face guarantees the best electrical arc for proper fusion. - Polish the installation area until it shines bright before aligning the female thread vertically - Strike a small tack weld first to lock position then proceed with full penetration passes - Chip away slag carefully so the internal thread stays untouched and perfectly sized This handy setup keeps your threaded holes perfectly aligned for heavy duty rigs.
