Hi Gang

  The cutout detail  (6W6)of the top and bottom cutout on the rib blanks (except rib 9) is 10 mm wide. Should that not read 5 mm??

 I have made the rib blanks and am just about to make the cutout for the spar doublers on the top and bottom.

 . Since the spar doublers are only 5mm thick, why would the cutout be 10 mm??

 Is this a misprint??

 Thanks for your help in advance.

Hi Ron,



Have a look at 6-W-3. If you look at the spar details you will see that the spar cap is 1/4" material, approx 6-7mm. Then the doubler which is 0.032". The cutout needs to clear the doubler and the spar cap, hence the 10mm.



So I have used the 10mm cutout in my cutting blocks. In fact what I have done is left that section in the cutting block and drilled the relief hole only, so I can use the cutting block to drill the hole through the metal blank in the correct position, then trim the cutouts later.



Hope this is not too ambiguous.



Regards, Glenn

Thanks for the reply Glenn.

 Was kind of thinking that the gap did not need to be a wide as it was. Mark Townsend (CanZac Aviation) also explained this to me. 

 The idea you had for your cutting blocks is a good one!

 Thanks again for the reply

 Ron

Hi Gang

 On the rear ribs, the top, bottom and spar flanges are bent in the same direction (according to note on the bottom right of 6-W-6). of course they are installed either facing inboard or outboard as stipulated.

 

  Watching the Metal working DVD I noticed that Rib 3 has the spar flange bent 90 degrees opposite to the rest of the flanges. What other ribs have this?? Not clear, at least not to me in the plans. Anyone know where this info is?? 

  Actually, I think I am staying up too late at night in the workshop. Sorry for asking so many questions. Just when I think things are as "clear as mud" I end up second guessing myself.

Hello Ron,



I don't know which flanges you are referring to, I finished

all ribs and am assembling the wing, but all flanges on each

of the ribs are bend in the same direction. Rib 4 is different

in the sense that the left and right rib are swapped so the

wing locker has the smooth side. Also on the rib with the

bell-crank the flanges for the two rear lightening holes are

in the opposite direction.

This is the way I did all, did I do it wrong or .......

Hello Ron,



I have seen Randy's pictures, I agree, these seem to

be bend the other way, I don't know how this fits

with my drawings. I think this is an issue with an

older design, if you look on the Zenith web site with

their free example drawings then 6W6 (from 2000)is

different from my drawing and indeed states that the

rib flanges for a number of the ribs are bend the

other way. They may have changed this for fabrication

convenience as it is easier when working with a single

form block to bend all flanges the same way.

Even the photo guide is confusing, one of the pictures

shows the rib supports (the small vertical L-angles on

the inboard side of rib #1-4), but all the drawings

show these supports in between the rib flanges so on

the outside of rib #1.



Regards,

	Maarten

  I agree with you. On the DVD metal scratchbuilding video and on Randy 

 Bryants homebuilding site there are pictures of the ribs with the spar 

 flange on the rib bent 90 degrees in the opposite direction (see 

 http://www.n344rb.com) and you will see what I mean. Until I can confirm 

 whether or not this is the correct way, I am holding off on my 1-4 ribs.

  Cannot find any reference to this in the plans, but I am sure it is 

 there somewhere one way or the other..

 Will keep you posted on what I find out

 Ron

Hi Maarten

  I phoned Roger at ZAC this morning. Just got off the phone. As per our drawings, all the spar flanges on the ribs are indeed bent in the same direction as the top, bottom and rear flanges of the rib.

 Apparently the older plans did this differently. Still, I am happy to put my mind at ease that I am going down the right path. 

  It is sure nice to have people to talk to and email to clarify any problems that are encountered.

 Mark Townsend up at Can-Zac is also especially helpful....and I am sure that he must shake his head when he sees my name on his call display when the phone rings!!! LOL
