Hi Mike,
They were going to be used on my current large floor standing speaker project.
During the template project, my wife was having another one of her (please be careful sessions
. But after all that work and putting her through a week of prayers, I decided on the ½ inch box joints instead using my PC template.
Why you ask, well the reason is that in order to cut 1 inch box joints in a ¾ inch thick wood ( walnut in this case) either you have to use a 1 inch router bit or make 2 passes using a ½ inch router bit.
If you use a 1 inch router bit, you still have to make minimum of 3 passes on the dept or the joints will break and also if you are doing two boxes which means 16 sides, it would be almost impossible to get all the joints perfect due constant to dept setting.
If you use a ½ inch bit, you will have to make minimum of 2 passes at full ¾ dept. And that also means on the second out-pass, you may break a joint.
So, walnut being as expensive as it is. I decided to stick to the plan and play it cowardly safe.
