Just a few new pictures to start with.






Getting a head.
Sorry for the title. What you see in the photos is the second attempt at the hammer head. The first one I made was a complete disaster. I made a skellington of plastic beams and discs and covered it with a thin (0.5mm) thick skin for plastic. Looked great when finished it but the next day it looked like a dead marshmallow. All the panels had sunk in. The fumes from the MEK glue had softened the plastic from the inside and they had sunk in. I had not cut holes in the bulkheads to let the fumes out. Lesson learned.
Head Number two.
Lessons learned.
1, Make it out of thicker plastic sheet
2, Cut holes in the bulkheads to get the fumes out.
With this in mind I went about redesigning the head. I made a model of the head out of PU foam minus the thickness of the plastic sheet 1.5mm.
I planned to heat the plastic in the oven and while hot form it over the model using an old t-shirt stretched over it to give an even pressure over the whole model skin while it cooled. It worked like a dream and my son and I got it down to 10 minutes, 6 in the oven at 160°C and 4 minutes cooling off over the model. I made six half parts four very good ones and two in reserve.
Next I made a flat main bulkhead running the whole width of the hammerhead and to this I fixed all the other bulkheads. The formed parts where cut to a template I made of the model and fitted together with the main bulkhead running down the centre line.
Once it was all glued up I put it out side for a day just to make sure all he glue fumes were out of the model.
Cutting out the main cockpit window and the sensors bays was a long and difficult job I was not expecting this, but as I transferred the data from my computer model to the real world things didn’t work out. In the end I did it by eye and I’m happy with it but it was two evenings work to get it correct.
I planned to have a cockpit in my model with a few flashing lights just for show. I went the cheap way. The cost of a circuit board and led lights if I went this way would be 40 euros as this model is on the cheap I went with bike back lights some wire and LED lights the lot cost me 15 euros and I’ve got 6 blinking pattons to play with.
Thanks for reading, more next time if anyone has any question please let me know and I will answer them. Sorry it’s been a long time since I updated the blog two much work and life getting in the way.
