TigerTony Posted May 27, 2012 Report Posted May 27, 2012 (edited) My question with this is If I were to build a totally external port for a box out of MDF, Would it be okay if i had a bend in the port if its outside of the box? Edited May 28, 2012 by TygaTony Quote

TigerTony Posted May 27, 2012 Author Report Posted May 27, 2012 If the external port is going to be 8x5x31. The wood is .5" mdf. all external. I'm having problems Figuring out the cutsheet for it. If the port has to have a bend at 12" what would my cutsheet be? Quote
bkolfo4 Posted May 27, 2012 Report Posted May 27, 2012 (edited) Need more info. Is it 8 high x 5 wide, or 8 wide x 5 high? Is the port bending up/down, or left/right? Is the 12" dimension the inside or outside edge of the port? What are the external dimensions of the box?

TigerTony Posted May 27, 2012 Author Report Posted May 27, 2012 .5 mdf. Box height: 17 width and deph 18. port will be 8 height 5 in width. 31 length. its totally going to be external of .5 mdf. The port bend should be around 15-16 in. i remeasured my trunk to see what it is. Im getting confused on how the port will be cut from the wood. for each piece. Quote
TigerTony Posted May 27, 2012 Author Report Posted May 27, 2012 (edited) Would these be correct? I kinda just tried to figure them over a drawing. I get so confused with sketchup sometimes Port outer side 1: 8 Height 15 Length Port Outer Side 2: 8 height 15 length Port inner Side 1: 8 height 10 length Port inner side 1: 8 height 10 length I redrew this because it looked so cluttered with the .5" marks for the MDF thickness. but its all .5 mdf Port top + bottom : width - 6 in Length 1 - 15 length 2 - 15 length 3 - 10 length 4 - 10.

TigerTony Posted May 28, 2012 Author Report Posted May 28, 2012 Bump before i go to sleep. Just need a second check on my measurements before I cut them in the morning so i can get the box finished and everything in morning before it hits 90. lol. Quote
bkolfo4 Posted May 28, 2012 Report Posted May 28, 2012 The port in that drawing is only 25" long. Need another 6" to be 31" long (the port length is determined through the center of the port).

Port outer side 1: 8 Height 15 Length Port Outer Side 2: 8 height 21 length Port inner Side 1: 8 height 10 length Port inner side 2: 8 height 16 length Edit: Caught an error with the Top and bottom. If it is wrong. On my drawing its 15" for the side. wouldn't it be 15.5. and then 10.5? or would that be fine how it is at the 15 and 10. Port top + bottom : width - 6 in Length 1 - 15 length 2 - 21 length 3 - 10 length 4 - 16. Edited May 28, 2012 by TygaTony Quote
