Well the friend of mine that is also helping out with our build has just finish load testing our complete carbon fiber horizontal stabilizer with 550 lbs. He's a wizard with this stuff! Anyhow we hope to install this when were finished the wing with the exception of installing the bottom skins, for TC inspection criteria.

Well had a great weekend in the shop! Very productive! We have officially completed the sanding of the wing to profile! It took a lot of effort to get it as perfect as we could. Then we fitted the bottom skins to trace the outline so we can mask for varnish and glue, as well as set locations for wing inspection panels. We also got a start on our wing tips. Next will be to finish the wingtip blocking then bond in the top skins! Really hoping to have the top skins in by the weekend!
As usual thanks for stopping by! IMG_2151.JPG IMG_2152.JPG IMG_2154.JPG

Well I've been working my full time job all weekend, but have tomorrow off and will be spending the entire day in the shop. Hoping that tomorrow will be a big day. Plans are to match fillet/scarf sand the trailing edges to the ribs and the lower skin. If I can get that done, then we will be all set to start in on permanently installing the top skins.
Thanks for stopping by my little corner of torment!

More progress being made yesterday! We were able to finish profile sanding the wing ribs to trailing edge strips to lower skins. This was an important step to make sure we had a smooth as well as large bonding area when bonding the lower skin on to the wing and were it meets the top skin. Found a couple low spots that were more then what my personal preference is happy with, so I bonded in some filler blocks and will sand them to profile later this afternoon and then should be ready for top skin installation! These pics were taken before we finished, so these pics still show a bit left to go.
Thanks for stopping by!

Well it finally happened this past weekend, we were able to get the top wing skins bonded in place! It was nerve racking, and it almost came down to the last ounce of glue. I really thought I had enough to do it and have enough remaining to do a few other small pieces I have left. But after everything was done I only have 3 ounces of unmixed glue remaining! but it all worked out and am rather pleased with the results. This evening I will begin pulling staples out and flip the wing over to do a close inspection of how everything laid down and to ensure proper squeeze out and no gaps. Next project is to fit and install the complete tail section so I can start ordering cables and fabricate the elevator controls.
As usual, thanks for stopping by!

Well we pulled the tack strips up and was able to get the wing out of the jig and into a stand to inspect all the glue joints for even squeeze out, and to make sure there are no voids. We did very well! Happy to say we finished the detailed inspection with no defects noted! So now we set the wing aside for a couple weeks while we fit and rig the tail assembly to the fuselage so we can fabricate the pushrod tube for the elevator system and take measurements for the rudder cables. Once we get that finished I can order the cables, and then move back to installing all the internals in the wings and prep it for interior varnish and wing close out inspection with the MD-RA (Transport Canada)

Good morning all. Well I've been away for work for 2 weeks, got home on a Friday evening then left for Reno the following Sunday afternoon. Was there for a week then back home. Spent the week taking care of a few things around the house and was able to finally get back into the shop this weekend. Being out of the shop for a month has set me back a bit so I don't think were going to make it to Reno races this September with our racer. Which I think is the smart thing, prevents me from rushing to get it done and tested, maybe before its ready. So I will continue with my rigorous build schedule as planned and when its done its done. Things are really shaping up to be a fast airplane! I've taken a few suggestions from some smart people in this forum as well as added a few things of my own. More to follow!
But here we have the mock up for my rudder pedals with the brake master cylinders. This is just mock up and fitting, more adjustments to be made yet.
As always thanks for stopping by!

Hey all, were still at it. Seems the smallest of pieces generally take the most effort..Took me 2 days in the shop to get these 2 sets of aileron control horns made and fit in a manner that I was pleased with. but pretty excited that they are done! next step is to permanently install the wing side aileron mounts, then I can fit the ailerons to the wing. hoping to have the aileron functioning by the end of the weekend and hope to post a video!

well the wing build continues! got all the internals in and fitted, so I can make measurements for the required bushings and spacers to locate the outboard bell crank in the proper position. Also got to match drill all the aileron hinges to the hinge mount brackets. Hopefully today I will be able to drill and rivet in the anchor nuts. I still need to figure out how I'm going to bend the aileron counter balance weight so that it is parallel to the wing chord so to speak so that way the bottom skin relief fairing can be a small as possible. As well I still need to add some addition clearance for the main pushrod tube in the wing to account for any flexing that might occur so it doesn't bind up the control. The video is short but it is showing the aileron moving from the wing root bell crank. Keep in mind all bolts, and bearing were not secured or rigged properly. It was just to confirm clearance.
As usual thanks for stopping by!

Well work continues. More with the wing and some on the fuselage. Getting closer to a close up inspection. Started building the aileron balance weight cove, where the balance weight will live. Then a bit more on the fuselage as I traced out the horizontal stabilizer in preparation of cutting the carbon skinand the top close out panel for the tail group.

Dunno why but this picture just made my morning. Mixed construction parts on an evolving drawing with mixed tools including a circle template and lots of tape to transfer measurements and write notes. Just the epitome of a project underway. Thanks for sharing.

Hey Jay,
Thanks! Glad you enjoyed it! Its comments like yours that really drive home why I enjoy this forum so much, always lots of wisdom as well as random people giving small "kudos" to aid in keeping up the builders motivation! Thanks for that!

I try to do something every day, no matter how small. Somedays I get in the shop for an hour other times I might be down there for 10 hours. I try to make the task/goal obtainable with the time that I have that day in the shop. I like to see small goal get finished in the time I have, it makes me feel like the project is always progressing. It might be something like, "rivet 8 nut plate to the aileron hinge" for those days that I have only an hour. Other task might be to make templates, remove the tail assy, cut templates, re-install tail and check fitment and repeat as necessary (takes hours). So I keep a large white board filled a section for smaller tasks, and section for larger tasks. One pitfall of this system is that I often have completely different areas of the aircraft under construction at any given time. So I find the white board handy to keep track of it all. Also nothing more satisfying as permanently wiping a task from the white board!

Racer being interviewed is asked,” You must be brave to build a racing plane?” Racer, “I don’t know about that, but it sure is scary if I screw up cutting out spots in the bigger pieces.” Interviewer, “Oh, I can see that; being dangerous if you cut wrong.” Racer, “Not worried about that, if I screw up I’m last on the list to get another part. It will take two years to get another. And then the wife won’t stop nagging that this is a waste of money. “

Sure looks fast, sure this isn’t a gold winner?

TFF,
We sure hope so, we aren't expecting to win gold, but we really are hoping to at the very least be a contender!! Oh and truer words have never been spoken in regards to the wife!! HAHHAHAHA

It's been awhile since I posted but we've been away for 10 day to the races in Reno, and away for work. BUT we have been in the shop as much as possible. We've been able to spend the last 2 evening in the shop and have made some good progress.
Here's a list of the latest progress;
-entire bottom of the wing sanded/cleaned from the excess epoxy drippings/runoff
-decided and located on the location of the bottom skin access/inspection panels
-routered out the lower skin for the aileron counter balance weight relief
- scarfed together the plywood face plates for the leading edges
-And a pic of the airplane at a local car show we were asked to display at
More work continuing this evening!
As always, THANKS for stopping by.

Well I've been out of the shop for a while. Had to spend the month of oct and the first part of nov prepping and installing 115 fence post for my wife's horse pasture before the frost went in the ground. It took a lot more effort then planned on due to plenty of rain and trying to maneuver a skid steer in a muddy field. BUT its done and I am back in the shop.
I was able to finish up and paint the elevator pushrod tube, install it and run the cables. Also built a quick simple jig to lock in the starting point for the fuselage aileron, and bell crank to aileron pushrod tubes, and installed them. Lter this week I am hoping to put the wing on the fuselage to make the necessary preliminary rigging in the wings to check for clearances and function before prepping to close up the wing. I also got the pitot and fuel tank vent lines run in the leading edges. as well as started on the static system. So slowly pushing ahead, hope to be closing the wing by the end of November!
As always, thanks for stopping by, enjoy!
