Hope everyone had a Merry Christmas or enjoyed the Event that you celebrate at this time.
Did you all get all the neat airplane goodies that you wished for???
Glenn's day job has eased up somewhat and is now able to devote more attention the the Real important things...........airplanes.



Well we're going to get back at it with the top wing. It will be built in "one" piece and is about 96" long.
We will start by building up two "I" beam spars front and rear, then will be connected with horizonal shear webbing top and bottom making one big, strong box spar like the full scale.

Status: offline 		To try to keep the spars as straight as possable, I rigged up a clamping fixture to glue the parts in.
First I clamped a 1" square piece of alum. tubing, (about 4' long) close to the edge of my table. I then clamped
a 1/4 x 1 1/2 length of alum. bar stock to the back side of the sq. tubing. This worked very well for me.



Each spar section (36 inches long) is made up of 3 pcs. of 1/4 x 1/2 spruce, plus one pc. of 1/8 x 1/2 balsa.
You first laminate the 1/8 balsa to one of the spruce strip. You will need to do this on 5 pcs.

Status: offline 		The spruce strips were all pretty straight, you will always get some bow in them. Just arrange the
bowed sides so that when you clamp and glue them they come out as straight as possible.


Here you see how I layed the parts out and clamped them down. Oh, and don't forget to line
the fixture with wax paper, don't want to glue the spar to it.


I then placed several clamps down the full length. I then took a small piece of nylon block and lightly
tapped the top and bottom rail to make sure they were seated to the alum. tubing. Also did the same
thing to the webbing.
After I was sure every thing was as straight as I could get it I then ran a bead of thin CA down each
side of the webbing. Gave the CA a good time to set, unclamped it, turned it over and reclamped
everything again making sure it was seated again and CA'd the other side.
Again after the CA set, I went back over all the joints with thick CA.
Now, just four more to do.

camper, gutted it and will fix it up to haul the big birds.

Status: offline 		Ok, got the other four spars all glued up. One piece you will get the two pcs. for the spar
center sections. The center pcs. are about 18 1/2" at the wide point \ / .



I mitered the ends at a 60 degree angle to get a lot of surface for glueing.



Note that both splices on both I-beams will be in between the cabane attachment points, so
along with the shear webbing between the beams and 1/32 ply leading edge sawtooth sheeting,
it should make for a very light and strong wing.

Status: offline 		I set my champing fixture back up for glueing the spar sections together. Also drilled some
small holes in the mateing parts for the glue to lock into.



Mixed up some epoxy and coated both parts and clamped them together snuggly.



When set, I'll do the other three joints and I'll have two finished I-beams.

Here's the center section.

Status: offline 		Note the two ribs to the right side of the center section are 1/8 ply. This is where the
cabane attachment location will be. A 1/4 x 1/2 piece of spruce will be glued across these
two ribs in the notch just forward the front spar. A similar piece will be glued in between the ribs
just aft the rear spar. The reason the rear block is not notched in is that the rib being thinner
there the notch would break into the edge of the spar hole and weakening those ribs.
The cross blocks is where the cabanes will be attached.



Another shot of the ribs. Also the holes that the spars slide into are sized so that is a snug fit.
The wing is now ready to start assembling but I believe I'll start that tomorrow. I told Miss Mary
that I'd take her out to dinner this evening so need to start getting ready for that.



HAPPY NEW YEAR EVERYONE

With the under camber the TE of the ribs are pretty thin, so to keep from possibly breaking
these ribs I spaced the wing up so that it just clears the table top. I used 1/2" blocks seven
places under the spar beams, and clamped them down. I did not clamp them tight, just snugged
them down so that nothing would move. If all works well, it will come out nice and straight.

Status: offline 		Starting with the center section and working to the tips I used squares to align each rib,
when satisfied I used thick CA to tack two places on each beam.



Here we have all the ribs nice and square and all tacked in place.



I will now go back and double check each rib to make sure they're square and spaced correctly.
For final glueing I like to use thin CA so that it wickes into the joint well. When set I will go
back over it all with thick CA.

Status: offline 		That looks absolutely great! I have not had the pleasure to build a full kit by Glenn but I am doing his fabric now, installed a full cockpit kit and used his 2 piece cowl on my BUSA DR1. I may have to go after the DVI I think. We are lucky to have someone producing such products for all of us fans of WW1 aircraft. I will continue to admire this thread with great interest.

Status: offline 		Hi Del--good to see you making progress with the DRI--looking forward to the next steps-I have my DVI wings all ready for covering and the fuselage is 7o% done - just made the seat frame from thin wall stainless steel tubing -tailskid and undercarriage is finished and the dowled framework came out very good ,looks great with the wheels temporarily attached!--I am using a Zenoah 74 cc twin and will have to make a new muffler for it ,so there is still plenty to do, the tailplanes and rudder are not even started yet,but my Spandau 08/15 guns are finished as well as the controlstick which was abit of a nightmare to make!--I am just recovering from dental surgery and have to take it easy for a while--love your work and best wishes jo-go
