Estes Puma #7256 Build, Part 5, Dowel Guns and Wing Glue Line

GOTCHA: The instructions say to cut the dowel into 1" section. They should be cut into 1 1/2" long pieces. The outside edge of the wing is 1" wide, if the dowels were 1" long the dowel wouldn't extend forward beyond the joint.
In a blog comment, BAR Geezer mentioned this mistake in the instructions. Scigs 30 also found the error on his TRF build.

The tabs on the wing joint needed filling.
After sanding and another shot of primer/filler the dowel was glued on under the joint.
The dowel serves as a gun detail but also strengthens the joint.


The primer on the wing glue line was scraped off for a stronger glue joint.
On the left a line of glue was set down the line.
TIP: On the right side I'm evening out the line by pinching my thumb and forefinger together making a upside down "V". Run this down the glue line making an even bead of glue.

The center line of the wing was pressed into the glue bead.

    I’ve been playing catch-up, reading a lot of your old blog posts. I am amazed at the number of times you’ve found errors in the instructions. I’ve noticed it myself, but it’s been spread over a number of years, so it has not sunk in until now. I love the old Estes instructions with lots of text that go along with pictures. The new style from Estes are often very confusing, particularly the way dimensions are drawn.
