Life size Buzz's right arm started
Dear all
So I have made aa start on the final arm which is Buzz's right arm (the saluting arm). It is completely different from the other arms. Its method of construction kept nagging me that I knew this from somewhere else. Then eventually it hit me, large pipe bends like in the photo below So as usual, starting at the narrower "hand" end there was the former and first couple of sections Once joined I decided to reinforce the former join on the inside (see below) Then I started adding the next part of the arm which is not a full ring After this part the next few sections are all "segments" which meet at a single point (which is the inside of the elbow) I knew from my work on the 1/4 scale model, for the arm to work this "meeting point" had to be spot on. So I was very careful at this stage and tried to be as close to perfect as I could. I found getting all the curvature just right quite tricky Although slow progress it is fitting together really nice, so is paying off. Currently it reminds me of those air vents you see on the decks of steam ships in old films (picture below of what I mean) I am sure they have a special name but no idea what it is. Regards Kevin

I don't know either.
I am a little surprised that six hours after you have posted, no one has jumped in with the answer

Excellent post, thank you gotham.
Sadly no prize (not even a witty reply)! Regards Kevin

more on life-size Buzz's right arm
Dear all
So time has been in short supply for a while so progress is slow but at least still happening. So the parts are getting interesting and also more complicated to hold to get the gluing done since I have to get the glue tube inside the arm and "around the bend" to get the nozzle on the tabs. And then the final ring of the top of the arm is reached And attached Next up is the former and then.....more strengthening Regards Kevin

Dear all
So I now needed to fit the former to the top of Buzz's arm. As you can see the shape of the top of the arm it is not a "natural" curve and does not close up naturally. Also it has an important "sharp corner" so I had to clamp the former in place first before carefully gluing the former in place Next was to start strengthening. First up was to add an extra layer on the outside of the ends of the arm (below is a picture of the wrist end added) The it was time to add the first strengthening layer on the inside. That took a lot longer than expected. This arm is "very curved in all directions" (if you get what I mean) so this meant the strengthening parts could not be very big at all. Too big and they could not be deformed enough to be completely in contact with the arm which meant that essentially lots of air pockets were being made with no strengthening achieved. It was also a bit of a contortionist job getting to all the different parts of the arm and being able to press down firmly on all the bits of paper. I was quite nervous that I might puncture the arm. Eventually I managed it Now I just need to do it all again. Thankfully the the second layer is easier since the model is stiffer so has more resistance, hence easier to press down on. Also you know it can be done. Regards Kevin

Paper modelling - a relaxing pastime 😊
