I recommend you get a pneumatic cleco tool, after I built my RV wings I got a bad case of carpel tunnel. You will take those things in and out a million times before you are done.

How did those cap strip turn out? What you can expect. Looking at the photos of the cut strips. You can see that the 1st strip that I cut off the 4'x12' sheet had some residential edge stress left in it from the T3 tempering process. The little twist in #1 strip making it unacceptable. The next 13 strips that I cut off are as straight as an arrow, well within acceptable tolerances. Final width dimensions 1.255- 1.275. & There is enough material left over from the 4x12 sheet for a second set of cap strips. Cheers to ya all!Comment

a few more questions for you about the Evolution saw
there does not seem to be many retailers selling the saw in Canada, on the Homedepot.ca site they have a saw but its an orange version that does not seem to have the guide like your model has. Did you buy it directly from Evolution?...Amazon.ca does have it but I thought id ask you to see if there was a Canadian seller I could support...the amazon model looks like an similar version of yours
did you cut all you spar C channel with that saw also...I was wondering if it could handle that thin material if it was supported and the guides go that wide....or did you use a shear or other method to make those
does your evolution saw have 2 parallel guides for the front and back...or one guide the whole saw length..it looks like there is different guides between models..
ThanksLast edited by way_up_north; 02-18-2021, 01:15 PM.

Perfect looking ribs. You have a long way to go so make sure you have the radio on and do not take any long breaks. Breaks grow into weeks then months. It takes discipline to cross the finish lines. We hung pictures of nice looking Bearhawks and other aircraft that had features that we would like to use as a visual goal. Most important if you have a wife and/or family make sure that you still make time for them. Celebrate those MVP days and hoist an occasional beer to the milestone. (MVP=Major Visual Progress). You are off to an excellent start being able to build quality parts as it will give an amazing set of wings. I grin every time I look down our wings as they are clean smooth pieces of art that started out the same as you have. Plan, look ahead and have the materials waiting so the work flows through all its stages seamlessly. Congratulations on a great start.Comment

Spar layout & construction. I struggled with the possibility of being out of alignment front to back, drilling an incorrect sized hole in the wrong spot. Who knows! I am confident I could find away to make a mistake. Simply because the Main & Rear Spar share so many common measurements between them. So this is my solution. I made one pattern for both main & rear spars that are associated with each other on a full scale 8" x 8" x 15' piece of scrap I had laying around. This will also serve as a pattern during the assembly riveting process. Hit that like button if you find this stuff interesting! Cheers & happy building.You do not have permission to view this gallery.

Figure I post a weekend cheerleading picture. All layouts have been confirmed & drilling has commenced. Used a laser level to level the entire assembly up. So far the is good! Hair straight back. However I did start with the rear spars caps. Lol cheapest material if I do have a screw up:rolleyes:You do not have permission to view this gallery.

I want to share more information about layout & drilling caps strips with anyone who is reading these posts. It is very important when stack drilling multiple layers to make sure the entire stack is level. I am mean perfectly level use celecos to hold the caps strips assembly together. Drill in groups, front & back cap strips together lined up as they will be riveted on to the spar cap. Develop a system to keep track of which strip goes where! Keep your cutting tools & drill bits sharp. Doing this right means everything will line & your rivets will simply slide into the assembly with proper tolerances.

Hello, we have had some really cold weather here in CYQU - 45°C Craziness. However no fear here! We are all done pre drilling all spar caps. Moved on to jig construction. Here are some pictures of how the progress is going. Any questions feel free to ask or DM me would be best. Not overly talented at typing.You do not have permission to view this gallery.

Really making big progress now. Spars are going to be assembled very quickly on this jig. I could not find any measurable deficiencies with is jig. The jig worked out really well. Very pleased with myself. :cool: enjoy the pictures pound up the likes. ​​Comment

Good evening nothing out of the normal Just general cheerleading. Figured I would show you where I'm at on my right hand for rear spar & I moved to lightning holes that were conflicting with the pocket rib stations. Basically the two holes at either end of the aileron were moved. Inbroad holes 1.75 & outbroad 1.5Comment
-
I double checked my interpretation / calculations of the dimensions from the drawing. I am correct. However there's interference on either end of the aileron with the aileron skin 0.020 pocket rib stations on the rear spar.
Resulting in my decision to relocate to the lightening holes.Last edited by Sir Newton; 02-17-2021, 11:56 AM.

When you first posted your jig, i didn't understand what you were doing. Now seeing the spar on it, it makes perfect sense. Very cool.Comment
