I am working on the (1st) wing of my HDS TD VW Project. I thought I am the last to build this "dinosaur" [Wink] However, I did flip over once for now. Clecoed the skeleton and rear top skin, then flipped over onto a super simple holding device made out of scrapped shelves and some lumber , I had lying around. (see: http://www.petersprojekt42.de/PDRM0114_JPG_view.htm ) took about half an hour to complete. I ripped the contour from the second pair of rear ribs I have. Totally true and level and gives me the opportunity to move the assebly around on the table. I intend to complete the whole thing in clecos before I start riveting.

I see these brackets are held to the Rear Rib # 7 with (3) each A5 rivets. As the bracket receives force from the control cables through the bellcrank the brackets are pulled in to the rib, but as the bellcrank transmits that force to the aileron the brackets are receiving shear forces and transmitting that load through the A5 rivets to the rib. My question is: I do not understand the forces involved here to cause those rivets to fail in this location. Are rivets by design stronger in shear than in tension? I don't see a lot on tension force here - what am I missing? Also, are AN bolts stronger than rivets in this situation? No, I am NOT doubting the designer here, I'm just trying to understand this situation. Can't you tell I am at this point in wing construction? Thank you everyone for the suggestions, directions, and contributions made on this list for the benefit of everyone.

Goodings" Subject: Zenith-List: Re: Wing skins - getting it flat and straight! --> Zenith-List message posted by: "John M. Goodings" I read about builders who spend considerable time getting a work table absoutely flat and level. Let me suggest another approach which certainly worked for us. My son and I built our 601HD on an 8' x 4' sheet of 3/4" particle board laid across two saw horses; nothing was braced or levelled. However, I am a huge believer in right angles, straight lines and measurement. Wherever a right angle is called for (ribs on spar, etc., etc.), we used a large carpenter's square to make it a true right angle. Our rivet lines are dead straight; a stretched thread is very easy to use. The two halves of the aircraft (opposite wings, etc.) are dimensionally identical. If you do this, it MUST come out right. (Actually, it didn't; the overall left side of the fuselage from the very front to the very back is 1.5 mm longer than the right side!). When the wings were mounted with the aircraft on its gear, the tips are the same height from the ground within a mm; I'm sure this is partly luck. The aircraft first flew straight and level; like all Zodiacs I know about, it had a slight tendency to turn to the left. This was cured by a ground-adjustable trim tab 200 mm x 50 mm on the right, rear, middle aileron, angled down very slightly. No additional adjustment is necessary with one or two people in it. Presumably, one is holding a little more or less aileron, but it is not noticeable; essentially, the aircraft flies hands off, but I tend to fly it with my right wrist draped over the Y on the top of the stick. My point is, I don't think new builders should get uptight and stressed out about perfectly flat tables absolutely level. But I would spend effort in getting things straight, at right angles and dimensionally accurate. ________________________________ Message 5 _____________________________________ Time: 07:43:59 AM PST US From: LarryMcFarland Subject: Re: Zenith-List: Rivets for Aileron bellcrank bracket --> Zenith-List message posted by: LarryMcFarland Tracy, If you've not tensioned the cables past 20 to 25 lbs and not created a binding condition on the aileron crank arms, you should not see a problem. In flight, if you horse the controls around hard, you could conceivably have enough repeated force to damage the mounting area of the rib or loosen the A5s. Seriously doubt A5s would give it up without other things going on. I don't fly heavy on the controls at any time because of the risk of something working loose, or worse, over-stressing things. The walking action of the aileron control rod on the belcrank creates a tension on the A5s side to side and does a bending action on the rib if the forces are high enough. Yes, riveted fasteners are twice as vulnerable to tension as shear.

If you happen to have access to a simple transit or dumpy level for construction and site work, this can be used for wing frame leveling and setup to easily obtain a ridiculous degree of accuracy. By using this instrument set in the corner of the shop, and using shims, exact table leveling means nothing. I use strips of wood with spring clamps to rest on top of the spar ends, make a mark where the crosshairs hit, then move it to the other end and adjust as needed. Takes me about 20 min. to set up an XL wing dead level with the spar at the required 9 degrees.

I got reamers of the proper sizes (5/16" and 3/8") to drill the wing attach plates (CH601-HD), and the alphabetic size drills to go with them (N and U). So, tonight I made some holes in some scrap material, for practice. I expected the bolt to fit very tightly, but nope! They go through easily. Not too loose, but not tight. Same with both sizes. Then, for comparison, I made a hole with a regular 3/8" drill bit, and the results were similar, if not a bit tighter! Am I doing something wrong, or is the difference supposed to be that subtle? Here's how I made the holes: started with small drill bit and replaced it with a large one. Drill hole and repeat. Below is the sequence for each final size. Hole for AN5 (5/16"): 1/8", 13/64", 1/4", then N. Hole for AN6 (3/8"): 1/8", 13/64", 1/4", N, then U. Hole for AN6 (3/8"), no reamer: 1/8", 3/64", 1/4", N then 3/8" Note that the material was clamped to the drill press table all the time. I did have to lower the table one or two inches in order to mount the reamers. This is the only thing I can think could have thrown the process off track. One more question: to avoid the adjustment step, I could cut the reamer's shank. Does anyone see a problem with this? Thanks in advance for your toughts / comments / blank stares.

You can get precision ground aircraft bolts. If you can find them as surplus they are reasonable.

Perhaps you can select AN6 bolts that run toward the maximum diameter. The corresponding close tolerance bolt, AN 176, has a max diameter slightly greater at .3742 and the minimum is .3737. For a 5/16 AN5 bolt you could substitute the close tolerance AN175. Again the minimum diameter is larger for the close tolerance bolt. Bolt strength is equivalent in each case.

When Crawford had them, they were selling them $46.00 per thousand and $22.00 per thousand for the A4's... I ordered 4000 of the A4's from them today... After doing the math, I think I'd be better off buying the minimum order of 8000 of the A5's from Crawford, at $368.00 and maybe trying to resale what I have left over... The A5's is where I'm really struggling right now, as I'm fresh out of em'! and I need them before I can proceed with my wings... Thanks!
