Aug 13, 2023     Elevator Assembly - Continued       Category: Tail Feathers
Ok. Back to the project. Used long bucking bar to install rivets on the rear spar of elevator. Not an issue at all, #3 rivet gun @ 37PSI. Used PVC pipe on pop- rivet squeezer for leverage on inner LP4-3 blind rivets. Rear spar LP4-3 bilnd rivets were easy with the Harbor Fright Pneumatic Squeezer. Front Spar a little difficulty with rolling rivets (mostly cosmetic, sorry Tony B) I think we need to use other longer dies for the pneumatic squeezer as I suspect the long travel may be the issue.


 
Jan 03, 2023     Back Riveting Ribs to Skin - (3 hours)       Category: Tail Feathers
Getting pretty fast back riveting the -3.5 rivets used 35PSI #2 gun, for the -3's dropped it to 30PSI. All went well except found, after finishing the top right skin, there was a rib without sub-dimples, Ope! (Mary!!!!!) Drilled out 8 rivets without an issue, dimpled rib, then promptly set the 1st rivet at 90PSI! (wrong hose) Oh, well, something wrong on all sub assemblies will humble a builder.... just a slight deformation on the upper skin. in retrospect, I probably should have just left it alone the 90PSI rivet was pretty flat, but still had 7 nice rivets to take up the slack and it was in the center of the rib. Shhhhh!


 
Jan 02, 2023     Elevator Assembly - (9 hours)       Category: Tail Feathers
Started assembling Elevator, riveted Tip Ribs, had missed the 6X end dimples (can't use DRDT, needed pneumatic squeezer) Also, sub-skin dimpled 6X holes at skin/counterweight overlap. Seems rivets don't sit as flush after expoy primer, unsure if from under dimpled or excessive primer. So I re-dimpled one set of counterweight skins, appears to have helped. (Cannot feel any rivets with rub test before re-do, but was optically annoying) Ran short of about 5X -5 rivets for doublers. unsure why, maybe too many previous misteaks. Ground down a few -6 rivets to length to make up difference. Will order more just for stock. Elevator horns, little tough to install rivets into holes, again, suspect too much primer in holes, scraped out primer for install, and actually just reamed a few holes. Prepped back rivet plate and re-waxed.


 
Dec 30, 2022     Elevator and Trim Skin Dimple, Priming Innards - (12 hours)       Category: Tail Feathers
Mary dimpled the 4 elevator skins and the 2 trim skins. I prepped the paint booth for priming and added additional masking of rear spars for foam ribs. Epoxy primed all elevator and trim tab parts that were previously alodined. Counterweights trimmed, Fubar'd one weight, so I re CSK hole on other side and filled front side, each set weighs in at 1125 gms. Prepping the lead weights, rough cut weights on bandsaw with a 6-TPI blade. The blade normally used for cutting the aluminum ribs is a 24-TPI blade, too fine for lead. A farrier hoof rasp made short work of the remaining trimming, as well as the high ridge on the back side of two of the counterweights.


 
Dec 29, 2022     Prep and Alodine Elevator and Trim parts. - (7.5 hours)       Category: Tail Feathers
Alodine preparations, cleaned all metal with acetone. Alodined all elevator parts and trim spars/hardware, hanging to dry.


 
Dec 26, 2022     Etch Prime Elevator Skins - (7 hours)       Category: Tail Feathers
Elevator and trim tab skins prepped for Etch Priming with skins masked for foam ribs. Used orbital sander with maroon scotebright to clean off micro scratches. all parts primed with SW P60G2


 
Dec 24, 2022     Trim Tab Horns - (2 hours)       Category: Tail Feathers
Used opposite tab with cleco to mark cut lines on trim tab horn. Assures adequate hole spacing to edge.

Nov 24, 2022     H Spar Rivering HS-1015 Stringer - (8 hours)       Category: Tail Feathers
Ah. The dreaded HS-1015 Stringer Invisible Rivets. I have been riveting in a horizontal position placing the frame on two banker boxes with a soft blanket to position. For the invisible rivets I balanced the tungsten rivet bar on my first two fingers and pushed up on the rivet. After placing the rivet gun on the skin, I reposition the rivet bar to "feel" a horizontal position. A known burst of the gun set the rivet to pretty darn close to what I wanted. I used a telescoping mirror to inspect results, all worked well! (Black Gorilla tape is used on bucking bar to protect stringer from damage.) PM me for a video of this technique if desired - dl


 
Nov 23, 2022     Bottom and Top Skins - (7.5 hours)       Category: Tail Feathers
Riveting Nose Ribs. After IA look of progress, installed forward spar with pop rivets and began riveting skin to forward spar.


 
Oct 29, 2022     Elevator Parts placement and Tip Ribs - (4.5 hours)       Category: Tail Feathers
Adjusted tip ribs for match counterbalance of skin. Bend closeout tabs and ream holes as necessary.


 
Oct 28, 2022     Elevator Gusset - (7 hours)       Category: Tail Feathers
Tip Ribs adjustment, really scratched up. Installed gussets and reamed holes to final size.


 
Oct 05, 2022     Tip Ribs - Long Day - (6.5 hours)       Category: Tail Feathers
OK. Spent considerable time tweaking the Inboard and Outboard nose ribs to straighten them so as to align to the Counterbalance Skin. Finally got what I deemed acceptable, Reamed the 3/32, 1/8 and 3/16 holes, no problem. (Page 9-2 Step 4-6) Then on to Step 7-8 for the Shear Clips. Finished the night with Page 9-3 Steps 1-3, for the Close-Out tabs. Used a part from a metal bending brake covered with blue painters tape to protect. DId NOT use rivet gun set on low, simply tapped with a piece of white oak scrap full length of tab.


 
Oct 04, 2022     Elevator Tip Ribs, Spar Adjustments - (1.0 hour)       Category: Tail Feathers
Verified spars were still at 90 degrees. Didn't like the looks of the original tip ribs from Vans (E-903, E-903), so I ordered replacements. These tip ribs are not much better, in pretty bad shape, scratches, some corrosion, serious Scotchbrite work was needed on them. I will Alodine and Epoxy prime but still, needed to repair before attempting to shape.

Prepped Ribs/Misc parts for Alodine Process, (Scotch Brite defects and Acetone wipe) Let parts cure for a few days before epoxy priming them, also (scotch brite was completed before dimpling) and primed inside of skins


 
Apr 24, 2022     Counterinking HS Spars - (8 hours)       Category: Tail Feathers
Decided to jump ahead and perform Step 8, Pg 8-8 to countersink both HS spars, doublers and ribs. My process will have these items Alodined and epoxy primed, thus wanted to do machine work prior.


 
Mar 05, 2022     Rudder Counterweight Install - (4 hours)       Category: Tail Feathers
Had fun forming the LE for the Rudder Counterweight. After folding skins I found I was slightly off on my initial fold line. to prevent a crease I took the lead weight and carefully used a propane touch to melt the outside edges and have the molten material flow towards where the screws would soon come though skin. Allowed to slowly air cool and then tamped remaining slight high areas with ball peen hammer to final dimension counterweight. I also etch primed the overlap skins for protection. The apparent "Line" in the finished primer image is actually from a double prime, I moved the blue masking tape and thus have extra layer primer toward seam. Came out sweet! (Was able to defer page 7-10 Step #4 as there is zero "pillowing" )


 
Mar 04, 2022     Rudder Leading Edge - (12 hours)       Category: Tail Feathers
Went to Lowes for the 1 1/4" dowel for rolling the LE. Cut a small 6" piece off the roll for the smaller LE at the top of the Rudder. NOTE: If dowel diameter is too small, i.e. 1"; the leading edge radius will be too small with the edges meeting in a V, if the diameter is too large, i.e. 1 1/2" the LE radius will be too large with the edges meeting with a large gap, i.e not flush. I used a pipe wrench and vise grips which allowed me to relax and hold rolled LE skin in position as all the metal slowly stretched (solo operation). Duct tape was all I used on the skin and dowel. I also used my fingers to final shape the last 1/2" of the skins to make a nice overlap (See progression images) Be patient, learn YOUR technique. I also etch primed the skins due to the overlap both on the LE and the Rudder counterweight. Bought the "Harbor Fright" pneumatic riveter which after adding oil and practicing on scrap, worked just fine (used a rag over outlet as it sneezes oil when tilted on its side)


 
Mar 03, 2022     Rudder Trailing Edge - (10 hours)       Category: Tail Feathers
Jig set up for the pneumatic riveter and special flush rivet tool (Cleaveland Tool) set the trailing edge rivets in 4 stages of setting (light touch just enough to hold into hole, 1/32 more, 1/32 more, then final seat), initial squeeze was on the centermost rivet, then #10 left, #20 left, #10 right #20 right, then #5 L-R, #15 L-R, then marked remaining A-B-C-D. Pneumatic riveter was on a caster cart, thus able to roll left and right without disturbing position of trailing edge.


 
Dec 31, 2021     Rudder Innards Assembly - (2.0 hours)       Category: Tail Feathers
Assembled the innards for the Rudder. Pneumatic Squeezer really made things smooth and sweet! Also, took VS and Rudder skins into paint booth to Scotch-Brite inner surface and clean with M.E.K. Will touch up with SB and Acetone before acid-etch priming interior surfaces.


 
Dec 29, 2021     Assembly of Vertical Stabilizer (sans skin) - (12.0 hours)       Category: Tail Feathers
Assembled parts for Vertical Stabilizer, times included making a leveling jig for the pneumatic squeezer, countersinking a few missed holes on rear spar doubler and etch priming results. Good practice drilling out deformed rivets. Will ask Wife for assistance on riveting skins. VS all ready for skins. But will assemble Rudder next as I need to etch primer the interior surfaces of the 3 skins. (Note: While proofreading entry and images I noted a missing AN426AD4-7 rivet! Dumbass!)


 
Jul 01, 2021     Still on the road Category: Tail Feathers
Still on the road working, usually off just before OSH, then we'll be back in the shop. Look for me at OSH, I'll be wearing a ball cap and sunglasses, oh, and a Hawaiian shirt
 
Apr 26, 2021     Back to Work Category: Tail Feathers
I'm back to work for a while. Won't be in the shop until further notice.
 
Feb 02, 2021     Rudder - (10 hours)       Category: Tail Feathers
Lots of prep for Rudder skins. Then cleco assembly to check if match drill (reaming) is needed on holes. Some parts are now final drilled from Vans so I can check sizing, inspect and debur as needed, then dry assemble for fit. Trailing edge piece is final drilled also. (Lucky-Dog!)


 
Jan 22, 2021     Rudder - (6.0 hours)       Category: Tail Feathers
Assembled bottom rib, attached rudder horn for final drilling (reaming) and MACH CSK. Built up all stiffeners and reamed #30 holes. deburred all holes, getting ready to dimple skins.


 
Jan 17, 2021     Finishing Up Vertical Stabilizer - (8.5 hours)       Category: Tail Feathers
Finished dimpling skins and spars, machine countersinking areas. Ready for conversion coating and priming. Going to jump to rudder at this time.


 
Jan 13, 2021     Vertical Stabilizer Rear Spar Day - (5 hours)       Category: Tail Feathers
Fun Day! Machine shop fun. All focus on Rear Spar, reaming, countersinking doubler, rough assemble VS sans skin.


 
Jan 12, 2021     Vertical Stabilizer - (5.5 hours)       Category: Tail Feathers
Match drilled Vertical Stabilizer rear spar and assembled for final drilling 1/8 holes tomorrow.
This build incorporates the SB-00002 Dated November 5, 2020 for the RV-10
Which changes the RV-10 bottom rudder hinge bracket. New part VS-XXXX (i'll look it up tomorrow) installed.


 
Jan 11, 2021     Rudder Stiffeners - (6.0 hours)       Category: Tail Feathers
Finished trimming, deburring and polishing up Rudder Stiffeners. Problem with a large shop is when you set down a small piece of aluminum, there are a lot of places your need to look to finally find it. Also designed tooling and jigs for new drill press and scroll saw.
