no. they dont equal out. i dont know what total length on either is because ive had this same question. your port on the second picture will be 2 inches longer then the first. i do know that. lol
well i mean the port will be the same width all the way through. what i dont know is when i make the bend i dont know how much longer to make the port.
Do i measure from the port opening to where the bend is then whatever length i still need to make the total length of the port i make with the second peice of wood for the port.
OR
Do i measure from the port opening to the back wall of the box then whatever length i still need to make the toal length of the port i make with the second peice.
port is the same width so where it bends u draw a 45 degree line there in the middle & continue the length as needed ...u measure along the centre on the port ...hope i explained it clear enough ...
