undercarriage in progress...... drilled holes in the table top to locate ( hold ) the wire so i could bind in copper wire and heat it up and solder. good time to check the angles alignment

After Stuarts build marathon i was inspired and started to assemble more parts, got Gwyn to laser cut some nice 3mm ply for the false LE ...... Which i thought was balsa for some reason. The front top and bottom ply wing skin will be butt joined to the false ply leading edge and will cover over the TRAILING EDGE.

Just wanted to show the cut quality of the ply Gwyn did for us. With even my average building board and really average skill i still managed to have a near perfect joint line. one thing that confused me for a while is the ribs 1 - 4 to make sure i had the spar outer tube going in a downwards angle from r1 toward r4 PLUS remember to tilt r1 so that when the spar is added it is a positive wing dihederal......i ordered a few spare r1 and general ribs just in case..... yes i am that guy!!!

Here is another interesting item, cut the wing tip false LE early to the angle you need for the slanted wing tip - after double checking to make sure u have the correct "top " of the wing. The ribs for holding the wing LE pin dowels have holes in the wrong space but since you need to fill a lot of areas with solid balsa for added strength u seem to be able to just sand away what you dont need - i made some rings and will cut away what i dont need.

Well this is it for now....starting the other side and will team up then fill the solid balsa and then the skins, just trying not to stuff up and make the left a left and the right a right wing !!! Join then reinforce / double check etc etc .....

One thing i did do was to tack cyno the ribs / tube and spars first with medium cyno then wood glue all sides and pack with lots of weight and leave to dry for 2 days.....so far so good.

The false leading edge is balsa. No harm to make it in 3mm ply but it will make the wing heavier and it is a little more difficult to shape prior to sheeting.
