MK111 wing construction., Mk111 aileron control.

Wing tip G25 mod I put the plate under the ASI and the Dcell skin for a smooth finish which in the end gets covered anyway. The large box section was hand hammered to fill the gap, you can see the smudges left behind by the nylon mallet.

And the finsihed wing shrunk and sounding like drum, the tell tale sound that lets you know the tension on the skin is just right. Its best to keep the heat away from the aeras that have already been done as the flow of hot air will loosen up the panel prevously shrunk as can be seen here. no big deal to fix but its better to limit the shrinking to only what is needed to stop the scolloping effect on the trailing edge, which I managed to aviod sucsessfully by carefull heating.

more of the tip and wing ready to be shrunk, ready for finish tape and painting. Its a good idea to wipe the inside of the clear surfaces with a soft damp cloth to clean the finger prints and dust off then warm any excess moisture out with the heat gun before you seal up.

Great job Wayne! Looks like it's really coming along nicely. You are really getting close to finishing this up. Keep the pics coming too, we all love to see what everyone is up to.

Just a pic of the heat gun it was a medium priced unit @ $65.00, it has varible heat from 150c to 650c, I set it at 500c for the clear stuff and 350c for the Dacron.
My test gun was a $20.00 job, In the end any cheap heat gun or source will work and I prefer to go slow and 'chase' the ripples out with control and always let the air flow go away from where you have done, a 'ghosting' effect is visible from the heat so you can see where you up to, I did not stop until the entire panel was finished usually about 6 or so minets each at the most. You could go faster but when your arm starts to get tired be carefull not to touch the tip of the gun on the plastic you wil get away with small touches at that heat or less, but if push the suface hard it will melt and you will have to patch it up.
A really good idea is to hang the power cord in the middle to allow reach and not put excess pressure on the clear stuff whilst shrinking as you can see the cord here doing just that.

Then when all the heating is done you get to put the wings back on.
