Priming - Wing Ribs and attachments 14-3-4

Image
I took advantage of a break in the rain to work on priming the wing ribs and attachments. As with previous priming, I first wiped of any markings on the parts using acetone, however since there are a number of similar parts to be primed here, I also attached labels to each part so that I could easily identify its place in the wing. Wing rib attachments cleaned and tagged for easy identification I labeled the parts by their wing side (Left or Right) and rib position (pictured above, the 1st and 7th rib starting at the inboard end of the right wing) Ribs were labeled similarly R1 to R15, and L1 to L15 I then used EkoEtch to clean and etch the aluminum surface. I did take the labels off the parts for this, but was careful to keep the parts organized. All wing rib attachment parts were etched and left to dry thoroughly prior to priming Wing ribs were etched outside as it was easier to clean them off with a garden hose due to their size Slowly working my way through all 30 ribs, 2 at a time

Using the clecoed left wing as a reference again, I continued to dimple the right wing parts prior to priming.  These include the Upper flange on all but the 4 most inboard wing ribs (except the holes that attach to the main spar) Lower flange on the 2nd and 3rd inboard most wing ribs (except the holes that attach to the main spar) The flap hinge rib holes that attach to the skins (expect for the inboard most flap hinge rib holes that attach to the top skin) Remaining holes in the rear spar top flange Top skin J-channel stiffeners Torque tube bracket flanges Rib flanges dimpled as described in the plans, with the exception of also dimpling the holes along the bottom of the second and third inboard most ribs (because those are easier to dimple now) Rear spar upper flange fully dimpled (except for holes that were previously countersunk) Skin stiffeners dimpled and ready for priming These were all dimpled using the DRDT-2 and pneumatic squeezer, however I again ran across a few gotchas fo

Wing Rear Spar 15-5-3

Leaving the left wing temporarily clecoed together as a reference, I started to dimple the right wing parts.  This includes dimpling the Lower flange aft tab on all the wing ribs 26 inboard most holes in the top rear spar flange Holes in the bottom rear spar flange that attach to the ribs Rear spar lower flange holes dimpled where the ribs attach Rear spar, 26 inboard most upper flange holes dimpled  These were all dimpled using the pneumatic squeezer, however I ran across a few gotchas for which I came up with the following solutions Dimpling the rear spar top flange using the squeezer was very tight due to the angle of the flange (less than 90 deg. from the web), and the yoke sliding across the web as the dimple dies came together left a fine scratch in the surface. I'm not worried about these as I will later prep the surface prior to priming, but to prevent the scratches for now I put down some masking tape, and this worked very well to fix this issue. Initial dimpling attempts

Mods - Aircraft Specialty (hose kit), Beringer (wheels and brakes) and Control Approach (rudder pedals) - delivery and inventory

In preparation for receiving my RV-10 fuselage kit from Van's, I decided to place orders for some third party items that I am planning on using in my build.  First off are Beringer wheels and brakes. I was very impressed with what I had seen online of the quality of these components, and placed my order for this kit at the end of 2023. In addition to the standard Beringer wheels and brakes for the RV-10, I have decided to include the following options Parking Brake ALIR Anti-Skid Regulator Sensair TPMS I had previously opted to remove the standard Grove wheel and brake option from my RV-10 fuselage kit order, and Van's honored that deletion when final payment was requested for that kit, so that also helped to offset the cost of the Beringer components. In addition to the Beringer items, I also ordered the RV-10 wheel and brake hose kit from Aircraft Specialty Flightlines, and in fact placed the entire order for hoses and Beringer components through ASF. Since I am also planning

Continuing on with preparing the wing parts for assembly and riveting, I took the W-1002 and W-1003 wing skins along with the wing walk doublers, and starting with the right wing deburred the edges of one set of skins and doublers. I then clecoed the right wing ribs and rear spar assemblies to the main spar. Next I took the set of top J-stiffeners for the right wing that had been match drilled using the main spar back in section 13, and inserted them into the notches in the wing rib top flanges. Note there are 3 holes that overlap where the J-stiffeners nest. Top skin and wing walk doubler edges deburred and ready for mounting Ribs clecoed to main spar and J-stiffeners inserted into rib notches I carefully took the W-1002 top skin (shorter one) and clecoed it to the main spar flange where the wing ribs also attach. I was then able to insert the forward wing walk doubler behind the skin, and cleco it in place. After clecoing the J-channel to the skin, I was able to slide in the aft wing
