This blog was created to detail the construction of a French ultralight designed by Claude Piel called the Onyx. It is built with sitka spruce and aircraft grade birch plywood. I will be fitting it with a Koenig SC-430 2 stroke radial engine.

I started tonight by marking the anti-tab rib locations and cutting the ribs for clearance of the trailing edge. Then I cut two 24" pieces of piano hinges into nice 4 inch sections. I played around and rivited a nut plate to one of the 6061 drag spar fittings. I finished the night by gluing one of the end ribs onto the anti-tab lower skin.

Sometimes I struggle with what I should or should not put in these posts. I spent part of my time this evening trying to get the control horn for the anti-tab worked out; I ended up scrapping that piece. I did order the aluminum from AS&S today so I will remake all of the structural fittings that have already been made. I decided that the main wing spar fittings should be made from 4130 so I ordered that too. I feel more comfortable with a bent piece of 4130 as part of a critical structure than a bent piece of aluminum. I also believe that the wing attach bolts are less likely to oval out the holes in 4130 than in 2024-T3.
I cleaned up the excess glue on the anti-tab and called it a night.

I put the second and third coats of varnish on the tab facing spar tonight then I glued the anti-tab trailing edge to the lower surface plywood. I put some more thought and research into the structural fittings for the plane. They are specified as 6061-T6 on the plans but 2024-T3 is the equivalent to the material on the original design. I will be remaking all of these parts now. I would have done this the first time if I had known that the extrusions were available.

I've probably botched the name of this spar a couple of times but I will try to be more consistent. I got home and cleared out the driveway right after work. Thankfully, my wife made a late dinner so I could work at that nonstop. I decided to glue the web to the tab facing spar.

Well, here we are in December and almost to the end of another hunting season so it is time to get back to some aviation related activities. I still haven't completed my flight training but I am hoping for nice weather next Monday. With Christmas around the corner I had to remove my fuselage from the living room. This required a reorganization of the workshop, materials, components, and workbench. If you remember, I left off working on sheeting the D cell for the leading edge of the canard. I was frustrated because it wasn't working out and I had to remove my first attempted section. I knew that I needed to get back down there and just fiddle around a bit and tonight was the night that I finally worked up the gumption to do it. I forgot how powerful it is to just be in the same room as your project. I spent a lot of time just admiring what I had accomplished so far. This led to some cleanup of excess glue here and there, then some organization, then marking the piano hinges to be cut another day, and ended by cutting and marking a new plywood aft web for the spar facing tab on the canard. I intend to glue it together tomorrow night. I needed to ease back into building with a non-threatening project like this and I'm not sure that it's the best time to skin a wing with our low humidity.

Well, after removing the tie down straps I noticed the the plywood was only glued to half of the spar caps in between the ribs. I decided to remove the plywood and try again. I have developed a new strategy that I intend to follow for the next panel. In the mean time, I have been cleaning up and reorganizing the workshop. Happy wife, happy life.

I cut and scarfed the two outer panels of plywood for the canard leading edge last night and then set up for gluing things together. I started tonight by squeegeeing a thin coat of T-88 to the inside of the plywood and then applied a coat of straight T-88 to the top and bottom of the spar and to the front edge of the leading edge stringer. I mixed up a couple of batches of epoxy and micro balloons and applied it to the edges of the foam ribs where they will meet the plywood. The final part of the night was spent wrestling the plywood to a nice fit on the ribs and spars. I used the wrong kind of tie down straps though, I think that I may invest in some ratchet straps for the rest of the panels.

Tonight I finished my scarf jig to the point of proof of concept. I wanted to make sure it worked before wasting too much time. The finished product is excellent so I will be working on the finishing touches over the next couple of days. I want to be able to use this jig for the rest of the scarf joints in this whole project.

After my last post I attempted to glue 2 pieces of the leading edge plywood together flat on a board. I tried to bend it around a nose rib after it cured and the interior plies of the plywood cracked radiating from the scarf joint. I was also very unhappy with the quality of the glue joint so I decided to start over. The first step in my new plan is to build a scarf joint jig using some melamine and a laminate trimmer. I was hesitant to make this post until I knew whether or not it would work but I have received a considerable amount of pressure from some of the readers of this blog requesting an update on my progress.
On the flying front, I have been very frustrated with my instructor, his schedule, weather, and lack of a DPE. The last two training flights were very unpleasant weather wise; so much so that I was ready to quit flying. I'm not sure what the next step is at this point. Just being honest here is all.

I cleaned up some excess varnish from the canard assembly tonight and then moved it upstairs with the other airplane parts. I decided to try sanding the scarf joints for the canard leading edge ply and sanded 4 of the 6 pieces tonight. I think that I will go back to my previous method for scarfing the plywood after I finish up the next 2 pieces; I think that the finished product is better with routed joints.

I didn't take any pictures from the last few work sessions as I have only been varnishing the same parts. I am now done with the varnish so I will move on to scarfing the leading edge plywood over the next week.

When I got home tonight the garage door was already open. Not a big deal, I figured my wife had her hands full with the kids when she got home. A little later we loaded everyone into the car and started pulling out of the driveway when the garage door bounced and opened again. I spent the next half hour trying to get the stupid thing to work to no avail so I called the installer back out to fix it. This is their 3rd trip back out and I think that they are getting tired of me. After all that adventure I went downstairs and started planing the leading edge stringer. I put another coat of varnish on the forward face of the canard spar and as I was applying the varnish I noticed that one of the nose ribs had slid while the glue was curing. I decided to wait for the varnish to dry before attempting my repair. After dinner and a movie with my wife I removed the offending rib and glued it back into place.

I started tonight by cleaning the excess cured epoxy off of the scarf joint in the leading edge stringer. Once it was cleaned up I mixed a batch of slurry, epoxy and micro balloons, and I glued the stringer in place.

I varnished the canard spar between the nose ribs tonight after I cut and glued the scarf joint for the nose rib stringer. My varnish cover must not have been sealed, so the little bit of varnish that I had left was cured. So off to Wal-Mart's aviation department I went.
I made an intermediate stop at Jane's Field (KANE) in Blaine to sign the paperwork on N43044. I am officially an airplane owner!
Once at Walmart I found the last can of Minwax Helmsman Spar Varnish, Clear Satin. I was unable to find any more 1" foam brushes in their paint department. As I headed over to get my son a snack, he was my patient partner in the night's nonsense, I lamented the inevitable trip to Home Depot. I decided to check the craft department to see if there was an alternative solution there. Boy was that a good idea! Instead of paying $0.63 per brush, they sell a 4 pack for $0.97, even better than that is the 25 pack for $4.98. That's only $0.20 each.

Now I fought the urge to title this post with a condom joke so I deserve credit for that. I marked and cut the notches in the nose ribs tonight that will hold the leading edge stringer. As I removed the stringer from its storage location, it broke into 3 pieces; so I will be gluing it back together over the next couple of days. I figured that my bad luck was out of the way so I mixed some epoxy with some micro balloons and glued the nose ribs to the spar.

Woohoo, my Blogger app is working again! I learned something this weekend, never use packing tape on plywood. I have spent about 3 hours cleaning off the residue. After that I drilled the mounting holes in the spar for the forward hinge fittings and I cut the spar tips at an angle. I finished the weekend by tracing the locations for the foam ribs and playing around placing them in their approximate locations.

I freed the canard spar from the build table tonight and then I removed the extra plywood from the edges of the spar with my plane. Then I removed the packing tape from the plywood that I had used to close the vent holes while I sealed them with varnish. I cleaned the tape residue from one side of the spar and that was about all I could handle tonight.
I was thinking more about a name for the airplane tonight. Every plane deserves a name and I believe that I have found a fitting name for this one. Due to current events, I have chosen the name Nikolina.

I checked the straightness of my plywood masterpiece this morning and it was slightly off. So tonight I used spacers against my straightedge to keep things in line. Before gluing the next scarf joint, I cleaned up last night's work.

I bought the book on Google Play called Avions Piel today for about $15 which may seem like a lot for an e-book that is in another language but there are 20 pages dedicated to the Onyx line of planes and 8 pages of pictures including the prototype that was built by M. Gangloff. I am not very good at French, as previously demonstrated but I can follow most of it. I typed it out in Word just in case a kind soul will have mercy on me and translate it into English. I wish the author would translate the whole thing into English as it looks to be an excellent resource.
I cleaned up last night's scarf joint tonight and then glued the second scarf joint that will end up in the middle of the canard spar sheer web. The grain directions at this joint are perpendicular to each other.

I brought my single piece of 1/16" 45 degree bias Baltic birch aircraft plywood to work today so I could cut it into 4" strips and cut scarf joints on the strips. These strips will be used for the shear webs on the canard spar. I figured it would be best to get this out of the way so I don't run out of things to glue this long holiday weekend.
I sized and glued four more vertical supports into the canard spar tonight. The twist is starting to disappear; I hope that this trend continues.

I had 20 minutes of free time before dinner tonight, so I cleaned the glue off the canard spar. After dinner, Maverick and I went to the Home Depot for some tape. He wanted to get a new flashlight so we found that first and then we started our quest for clear packing tape. You may recall from earlier posts that I like to use packing tape on my work surface because glue won't stick to it; or you may not. I found the tape but they didn't have a legitimate tape dispenser (they only had the crappy plastic ones that are a rip off and not reusable) so I enquired at the paint counter to find outif they had real tape dispensers. The person at the counter told me they did not but I could check in the moving department anyway. Anytime a Home Depot employee tells me that they don't carry an item I am encouraged because they are always wrong! I went back to the moving department and grabbed a tape gun and a couple of extra rolls of tape and I was on my way.
I checked the level on my workbench because of the twist in one of my spar caps and one corner was slightly off. I leveled everything and then set to work marking support locations on the spar and workbench. Then I applied tape to the work surface where I would be gluing supports in the spar. All of the vertical support members were then fitted in place and checked to a nose rib to make sure that I had the proper length. Each support member required some trimming on the band saw for optimal length. I completed the night by gluing the seven vertical support members in place. I need to figure out my shear web layout so I can machine my scarf joints soon.

Well, tonight was the night. I glued the forward hinge mounting blocks to the upper and lower spar caps. This means that I now have a spar and not just two spar caps. I had to size the blocks down in my planer to get the correct height to match the foam ribs and get the thickness to match the spar caps. When I was clamping everything together I noticed that one of the spar caps had a slight twist to it. I believe that this will go away once I glue the plywood shear webs in place. I just need to make sure that the webs are glued 100% flat.

I marked the location for each vertical member on the upper and lower cap strips and then cut the lower cap strip to its proper length. I trimmed the lower cap strip so they end at the outboard side of the last vertical ribs. I am not 100% sure that it was the right decision, but sometimes you have to make a judgement call and let the cards fall where they may. This will affect the way the wingtip foam is attached; for better or for worse, only time will tell. The next step was to glue the four 200mm hinge mounting block reinforcement strips to the upper and lower cap strips.

I got out the old block plane and cleaned up the top canard cap strip last night and then glued the third and final lamination in place on the top cap strip. I got up this morning and cleaned up the previous night's work. Things were getting a little messy so I vacuumed up the little shavings and chips that had accumulated. Then I glued the only lamination together for the bottom cap strip. I cleaned up that assembly tonight when I got home from the Twins game. I should be able to glue on the two forward hinge attachment reinforcement pieces tomorrow.

I ended up going out for my second solo cross country on Tuesday. Even though I logged 2.1 hours as p.i.c., I was unable to land at my first destination due to higher than expected winds, heavy turbulence, and being a low time / low skilled pilot I decided to tuck tail and return to my home airport. The experience did shake me a little but I will get back in the air soon, just not too soon.
My shipment of epoxy and hardware arrived from AS&S today! That is a good way to start the evening. I should have gone out and mowed the lawn but I was tired and my allergies were acting up a little so I decided against it. After dinner and taking care of the kids, I went down and glued the first lamination together of the top spar cap for the canard. This is a simpler spar as there are only 3 laminations making up the top spar cap and only 2 laminations making up the lower spar cap.
We made it to 5,000 hits on the blog this week. Not an astounding amount of traffic but pretty cool none the less.

I placed my hardware and T-88 order with Aircraft Spruce this morning. I promptly received a ship notice for the order this evening. Way to go AS&S! Meanwhile I spent the bulk of my night rebuilding the selector valve on my pool filter.
I managed to reward myself with some time to work on the airplane. I pulled the planer out of the garage and planed the spar caps for the forward wing. I finished the night by cutting the spar caps to length and cleaning up the workbench a little bit.
Sorry that there's no pictures tonight, a pile of wood just isn't that exciting. I hope to get some more solo XC time in tomorrow.

I spent a lot of time over the past few days doing take offs for hardware since the plans don't call out anything except the diameter of the hardware in only a few cases. I'm pretty sure that I have it figured out at this point with some exceptions.

I picked up my laser cut 4130 parts today for the front landing gear and the torque tube brackets. They tack welded the nose gear fork together; it looks pretty cool IMHO. I cleaned up the forward face plywood on the second rudder spar tonight, then I cut the holes for the rudder control horns in the forward faces of the rudder spars. I might have made them a little too big. Maybe I will end up filling them a little bit later on in the project. This is one of those details in the plans that is really missing the required information because the control horn needs to pass through both spars and attach to a bungee cord but neither hole is given.

I cleaned up the excess plywood from the forward face of the rudder spar that I glued together last night. I glued the forward face to the second rudder spar also. To finish off my night, I collected the prints together so I can complete some hardware take offs so I can get the hardware along with my next order of T-88 which needs to be placed soon.
I had another solo cross country scheduled for today, but the weather didn't cooperate.
