Title: What size rods for Brodak wing ribs?
Post by: Mark Mc on January 26, 2018, 04:09:38 PM: Can anyone tell me what size hole Brodak wing ribs use for building on a wing jig? I have a profile Oriental kit in the closet, and was wondering what size rods to get to build it.

Is there some reason you can't just open the kit and measure the size of the holes in the ribs?

Of course there is. Two reasons in fact.

1) Dozens, if not hundreds of Brodak kits have been built by guys here, and I figured someone would know off the top of their head without me making another mess digging the kit out before I have the bench cleared and ready to go, and

2) It's fun watching people hold it in and scream at their computer screen, "WHY DON'T YOU JUST OPEN THE BOX AND LOOK!!!"

So, how's that working for you so far? You could have opened the kit, measured the holes, bought the CF rods, built the wing jig and had the wing finished by now. Hang in there Buddy, hope you get an answer. H^^

Have you opened the box yet?? n1

Post by: wwwarbird on January 29, 2018, 05:49:19 PM: The holes are either 1/4", 5/16", 3/8", 7/16" or 1/2". It's also possible that there aren't any. If there is anything else I can help with just let me know. D>K

Post by: Mike Haverly on January 29, 2018, 07:01:55 PM: Better yet, follow the instructions. I'm betting you don't need rods for that wing.

Post by: Leester on February 17, 2018, 10:48:39 AM: OK Mark, How long has the kit been in the closet ??? If it is a laser cut kit it will have 5/16" wing jig holes. Check the Brodak web site and find the Profile Oriental and under additional items it list's the wing jig and states the jig will only work if the holes are for 5/16" rods. So if it's Die cut NO jig holes Laser Cut YES.
