Double Miter Corner Joint - how I mark out - cut with an angle grinder, and tack weld. @GavinClarkdiy

Uploaded January 2021 | Updated September 2026, 1 hour ago

I make a Double Mitre Corner Joint using square tubing, showing how I mark it out ready to cut, I cut the square tube with an Angle Grinder and tack weld it together.

I give my thoughts on this joint, leaving the weld without grinding it flat would make this joint look awesome on a project.

The Brand of the Drill bits and cutting/flap discs is "Alpha" If you can't get them at your local hardware shop, here is a link to Alpha Tools: https://alphatools.com.au

Always use all the correct safety gear, and use your tools safely. I am not a good role model for this.

Hope you found something of use in my video or at least found it entertaining.
