Getting on a bit......
After what feels like an age since I last sat at the modelling table, I had a quieter weekend this weekend, and decided to use as many spare hours as possible on the model.
I was getting bored with the wing, and wanted it finished...... It had gone on too long.....
I got started with the hand and upper arm....
Once I had completed the main parts of the upper arm, It was time for the first attempt at fitting the wire armature with spray foam........
I had done a few small tests to see how the foam reacts. Generally, it expands to thee times the initial volume. If by accident you put too much foam in a place, the foam will expand and fill the cavity more than you want. The foam needs a place to escape as it is expanding, this is important, otherwise the pressure of the expanding foam will blow the model apart at the seams. So, it is always better to add more if you do not have enough on the first fill. The foam uses moisture in the air to cure and harden. I used a very fine mist sprayer, like the ones on a perfume bottle, to spray a VERY SMALL AMOUNT of water into the cavity to be filled. First, I placed the pre-bent armature in position in the arm. I then sprayed in a small blob of foam, filling just under a 1/3rd of the cavity...... And, watched and waited with trepidation......
I needn't of worried, the foam filled the lower part of the arm perfectly.
I put in just the correct amount. The lower arm section is now filled and is very strong and withstands the crushing forces of my fingers....
Once the foam had cured, I attached all the nails to the ends of the fingers, to complete construction of the left wing.....
It was at this point, I had an idea...... When I looked at the pictures of the head of my model, the dragon looks like he has been around a bit and is not a young dragon anymore....... With this in mind, I felt that the trailing edges of the membranes of the wing, we too 'clean.' Fine for a young dragon, but this 'Grumpy-Old-Man' I was building needed an aged weathered look.......
With terror in my soul, I attacked the wing with scissors, hole punches and sandpaper. I tried to create a slightly ragged finish. I think it looks great. What do you guys think??? I feel it peronalizes the model as mine ...

Next, I hardened all the nail tips, and other weak areas with ca glue and then made a thorough check of the joints and any edges that I had missed with colour and touched them up with water colour pencils and a fine marker. Once I was satisfied with the finish, I sprayed the whole wing with three coats of varnish.
I will be back in a moment with final pics of the completed left wing.......
