I hope this is the correct place to post this.
I need to create a “duct” for dust collection on my mitre saw. Its a 6 in tall box that has compound mitre cuts on the corner and I am struggling. I have searched for videos on youtube and found things that are close but I can’t get it right.
I have the in side dimensions and material thickness. Top opening is 19" x 10" and the bottom opening is 11.75" x 6.75" and I am using .75 plywood.
I thought I had the angles at 30 and 15 but when I cut them with 45 degree in the corner the angles in the corner is too steep.
if there is a tutorial that would help I would like to learn this for future projects.
