RE: B-36 build thread and free plans
Mike, Mike, Mike, .... Hmmmm
Anyways, great photos! First, I see that you place them REALLY close together. You probably get more parts per sheet, but my extra spacing allows me to stray a bit. My scroll saw sometimes takes an unexpected turn. For me, the wood is cheap and disk sander takes off excess wood very quickly.
I hadn't used rubber cement with my paper templates, I used photo adhesive. This adhesive made it easy to remove the paper templates if you get to them in an hour or two but if you wait a few days it can be rather difficult to get the paper off. I also noticed that if I sprayed the photo adhesive on both the balsa sheet and the paper, the paper would shrink. I recreated my ribs a second time and sprayed only on the balsa sheet.
I will take this opportunity to comment about a scroll saw blade that I just came across. It appears to be a blank scroll saw blade with no teeth that has had very durable sanding particles adhered to it. I purchased a set last weekend at Menards and they work rather slick to sand the inside edges of very small areas. For example it would work well on the notches that I saw in the parts shown in your photos. I just thought that I would mention it.
