The pages on this web site document MY procedure and assembly of my Carden Edge 540I am by no means a professional or "master" builder and these procedures may not be the best methods for you.
Carden provides a nice construction guideline and color photos as an aid to building their kits.
I have chosen to build things in a little bit different order than they lay out in their manual

See How to figure out your beveling The wing will be thicker at the root end (left side) than the root end (right side) Determine the amount of angle you want and lay it out on the thick end (end view) Layout the same angle on the thin end (end view) Notice that the width at the top and bottom of the LE or TE is wider on the tip end than on the root end (i.e.. the root end almost comes to a point but the tip end is wider from the edge of the bevel to where the LE or TE meets the foam core) |

Work Bench I don't have plans, but I keep getting requests, so here's a little note on how I build my benches Essentially it's 3/4" ply, 8 feet long and 30" wide ( or whatever you feel like making it.) The ends ( uprights) are also 3/4" ply, cut to the height and width I want the bench, . I cut the left over 18" length wise into 6" wide strips, and cut off 1-1/2" from the length. This permits them to slide under the bench between the end panels These pieces are glued and screwd ( with 2" long screws) on the UNDERSIDE under the front edge, rear edge, and down the middle. These lengthwise pieces turn the bench into a bit of an "I beam" and make it very strong lengthwise. I put a pice of drywall on the table I use for building ( gluing etc) so I can stick pins in it. Easy to throw away and replace as needed. I have 3 of these benches in my workshop !! On the bench that I skin my wings and foam parts I use 2 pieces of 3/4" ply for the top. This provides a much sturdier surface. Since concrete floors are not always level I have leveled this table from end to end, side to side and also diagonally, so it is extremely level and warp free. I also have center supports made of 3/4" ply screwed onto the front and rear "under beam" that go down to the floor. I cut these perfecly to length after the table has been leveld and check for no bowing. these support more load on the table and prevent it from "wowing" in the middle. When I skin my big wings I put YET another piece of 3/4" ply on the top of the table, at one end / corner, as the "under pad" for my foam cores. This piece is cut slightly larger than the size of my 40% wing panels, about 2" bigger all around. I have a second piece that I put on top of the wing cores, on top of which I place my foot square cement patio stones. They weigh 20 pounds each and are easy to handle This upper pad helps spread the load out evenly over the wing core. I leave the cores to cure ( I use Probond) for 24 hours. |
