Tonight I spent some time with the wing fold mechanism on the Devastator.
These are two pictures that I took from my book by Steven Ginter. They show the details pretty nicely.
This gave me an idea. I didn't care about the wings being able to fold and then straighten back out to the flying position. This was one of the toy like features that were incorporated into the kit, along with the "deployable" arrestor hook.
So I studied this for a few minutes and came up with the idea to simply cut off the wing hinge pivot pins. They are two small rods molded into the upper wing halves.
You can see them in this picture.
Once this was done, the friction of the plastic actually is tight enough to hold the wing in the folded position. Plus now I don't have to fool with the small plastic squares that go inside the wings and are designed to hold the hinge pins in position as the wing is folded / unfolded.
In preparation of the Aluminum paint, I decided to glue the landing gear in place. This will make for a stronger joint, since no paint will be contaminating the plastic, and will allow the glue to adhere better. Normally I try to scrape off any excess paint at the glue joints, but by gluing the landing gear on first it will save me a step.
I wanted to replicate the small gussets found on the upper surface of the outer wing. You can see these in the wing fold detail photos. There are four of them on each side.
So out came the Waldron punch sets...
After determining the size needed to fabricate the holes that are in these gussets, I cut some plastic sheet material into a small narrow strip. Then I measured out enough material to make nine gussets, in case I messed one up.
Here's the punch set in action:
After the holes were punched, I cut the gussets into small triangular wedges to represent the gussets as seen in the photographs...
Here the gussets are glued into position:
Here both outer wings have been completed.
The next step was to fabricate the wing folding locking pin mechanism. It's pretty visible in the pictures. The Ginter book also has a factory engineers diagram showing just how it was built on the real plane. Pretty clever engineering by Douglas.
Once I had the locking mechanisms completed and glued into place, the next step was to drill out several holes that are seen in the detail pictures. Once this was done, I test fitted the wings in place again. Everything fit pretty good...
Here's a close up of the wing locking pin mechanism. On the real plane it was cable operated. The large round part is supposed to represent the cable drum... it's close enough for me.
Here's a final picture from a slightly different angle... It's starting to look more like a TBD.
Lastly, I drilled out the wing fold pivots. There are two different sized holes in teach part. Three holes in each... These should be painted silver if you're building a "Yellow Wings" plane, and should be "Blue Gray" like the rest of the wing fold interior if your building a camouflaged plane.
Next step: masking for "Aluminum" paint...
Please stay tuned. Thanks for looking and as usual, comments are encouraged.
