Batter Up Build Part 9 Contact Cement and Fins

Here's the first fin on the handle of the bat.

Remember, for contact cement to work, both adjoining surfaces get a brushed coating. Let the wet cement dry until it is dull, it should be dry to the touch.

Position carefully before pressing the parts together. The quick, strong grab will surprise you!

It's pretty apparent by the picture why I used extended tabs to glue on the fins. They probably wouldn't stick with any other glue except for the contact cement.

These fins do flex a bit from the root edge but are plenty strong for flight. The flex (and give) may help soften a hard landing.




The launch lug standoff was also glued with contact cement.






Here the excess glue is being rubbed off with a sharpened dowel. It'll take a few minutes to roll off the excess glue into little balls, but it will come off.

The lug standoff contact cement joint is very strong!
